  • How to html encode the output of an NHaml view (or any MVC view)?

    - by jessegavin
    I have several views written in NHaml that I would like to render as encoded html. Here's one. %table.data %thead %tr %th Country Name %th ISO 2 %th ISO 3 %th ISO # %tbody - foreach(var c in ViewData.Model.Countries) %tr %td =c.Name %td =c.Alpha2 %td =c.Alpha3 %td =c.Number I know that NHaml provides syntax to Html encode the output for given lines using &=. However, in order to encode the entire view, I would essentially lose the benefit of writing my view in NHaml since it would have to look like this.... &= "<table class='data'> &= " <thead> So I was wondering if there was any cool way to be able to capture the rendered view as a string, then to html encode that string. Maybe something like the following??? public ContentResult HtmlTable(string format) { var m = new CountryViewModel(); m.Countries = _countryService.GetAll(); // Somehow render the view and store it as a string? // Not sure how to achieve this. var viewHtml = View("HtmlTable", m); // ??? return Content(viewHtml); } This question may actually have no particular relevance to the View engine that I am using I guess. Any help or thoughts would be appreciated.

  • Why would it be a bad idea to have database connection open between client requests?

    - by AspOnMyNet
    1) Book I’m reading argues that connections shouldn’t be opened between client requests, since they are a finite resource. I realize that max pool size can quickly be reached and thus any further attempts to open a connection will be queued until connection becomes available and for that reason it would be imperative that we release connection as soon as possible. But assuming all request will open connection to the same DB, then I’m not sure how having a connection open between two client requests would be any less efficient than having each request first acquiring a connection from connection pool and later returning that object to connection pool? 2) Book also recommends that when database code is encapsulated in a dedicated data access class, then method M opening a database connection should also close that connection. a) I assume one reason why M should also close it, is because if method M opening the connection doesn’t also close it, but instead this connection object is used inside several methods, then it’s more likely that a programmer will forget to close it. b) Are there any other reasons why a method opening the connection should also close it? thanx

  • Update panel in Tab Container

    - by Sam_Cogan
    I have a tab container with 5 tabs, each tab contains an update panel. When the user initially opens the form, they can only see the first Tab, the others are set to visible=false. Once they have completed the first form, the hit save which sends a partial postback to save the data to the DB. Once that is saved, I then want to set all the other tabs to visible, however this does not work at the moment, I am assuming because the tab container is not contained in an update panel. How can I get this to work, do I need to put the tab container in it's own update panel, which will obviously then contain all the other update panels, or should I not use an update panel in the first tab and do a full page postback?

Is this doable?

  • A good way in Visual Studio to have user entered time frame?

    - by Ben
    Hi, Does anyone know of a good way to have a user enter an amount of time (hours and minutes) using visual studio controls? At the moment i have two numeric up downs, one for time and one for minutes that i then parse to create a timespan. The only other idea i have is a text box that a user can enter a "00:00" time in, and validate the input. Both of these ways seem a bit bad (in UI terms) though. Any ideas? Thanks

  • Refresh page isnt working in asp.net using treeview

    - by Greg
    Hi, I am trying to refresh an asp.net page using this command: <meta http-equiv="Refresh" content="10"/> On that page I have 2 treeviews. The refresh works ok when I just open the page, but when I click on one of the treeviews and expand it, the refresh stopps working and the page isnt being refreshed. Any ideas why this can happen? Is there any connection to the treeview being expanded? Here is the full code of the page: public partial class Results : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } // Function that moves reviewed yellow card to reviewed tree protected void ycActiveTree_SelectedNodeChanged(object sender, EventArgs e) { ycActiveTree.SelectedNode.Text = "Move To Active"; ycReviewedTree.PopulateNodesFromClient = false; ycReviewedTree.Nodes[ycReviewedTree.Nodes.Count - 1].ChildNodes.Add(ycActiveTree.SelectedNode.Parent); Application["reviewedTree"] = new ArrayList(); int count = ((ArrayList)Application["activeTree"]).Count; // Move all the nodes from activeTree application to reviewedTree application for (int i = 0; Application["activeTree"] != null && i < count; i++) { ((ArrayList)Application["reviewedTree"]).Add(((ArrayList)Application["activeTree"])[i]); ((ArrayList)Application["activeTree"]).RemoveAt(0); } } protected void ycActiveTree_TreeNodePopulate(object sender, TreeNodeEventArgs e) { if (Application["idList"] != null && e.Node.Depth == 0) { string[] words = ((String)Application["idList"]).Split(' '); // Yellow Card details TreeNode child = new TreeNode(""); // Go over all the yellow card details and populate the treeview for (int i = 1; i < words.Length; i++) { child.SelectAction = TreeNodeSelectAction.None; // Same yellow card if (words[i] != "*") { // End of details and start of point ip's if (words[i] == "$") { // Add the yellow card node TreeNode yellowCardNode = new TreeNode(child.Text); yellowCardNode.SelectAction = TreeNodeSelectAction.Expand; e.Node.ChildNodes.Add(yellowCardNode); child.Text = ""; } // yellow card details else { child.Text = child.Text + words[i] + " "; } } // End of yellow card else { child.PopulateOnDemand = false; child.SelectAction = TreeNodeSelectAction.None; // Populate the yellow card node e.Node.ChildNodes[e.Node.ChildNodes.Count - 1].ChildNodes.Add(child); TreeNode moveChild = new TreeNode("Move To Reviewed"); moveChild.PopulateOnDemand = false; moveChild.SelectAction = TreeNodeSelectAction.Select; e.Node.ChildNodes[e.Node.ChildNodes.Count - 1].ChildNodes.Add(moveChild); child = new TreeNode(""); Application["activeTree"] = new ArrayList(); ((ArrayList)Application["activeTree"]).Add(e.Node.ChildNodes[e.Node.ChildNodes.Count - 1]); } } } // If there arent new yellow cards else if (Application["activeTree"] != null) { // Populate the active tree for (int i = 0; i < ((ArrayList)Application["activeTree"]).Count; i++) { e.Node.ChildNodes.Add((TreeNode)((ArrayList)Application["activeTree"])[i]); } } // If there were new yellow cards and nodes that moved from reviewed tree to active tree if (Application["idList"] != null && Application["activeTree"] != null && e.Node.ChildNodes.Count != ((ArrayList)Application["activeTree"]).Count) { for (int i = e.Node.ChildNodes.Count; i < ((ArrayList)Application["activeTree"]).Count; i++) { e.Node.ChildNodes.Add((TreeNode)((ArrayList)Application["activeTree"])[i]); } } // Nullify the yellow card id's Application["idList"] = null; } protected void ycReviewedTree_SelectedNodeChanged(object sender, EventArgs e) { ycActiveTree.PopulateNodesFromClient = false; ycReviewedTree.SelectedNode.Text = "Move To Reviewed"; ycActiveTree.Nodes[ycActiveTree.Nodes.Count - 1].ChildNodes.Add(ycReviewedTree.SelectedNode.Parent); int count = ((ArrayList)Application["reviewedTree"]).Count; // Move all the nodes from reviewedTree application to activeTree application for (int i = 0; Application["reviewedTree"] != null && i < count; i++) { ((ArrayList)Application["activeTree"]).Add(((ArrayList)Application["reviewedTree"])[i]); ((ArrayList)Application["reviewedTree"]).RemoveAt(0); } } protected void ycReviewedTree_TreeNodePopulate(object sender, TreeNodeEventArgs e) { if (Application["reviewedTree"] != null) { // Populate the reviewed tree for (int i = 0; i < ((ArrayList)Application["reviewedTree"]).Count; i++) { e.Node.ChildNodes.Add((TreeNode)((ArrayList)Application["reviewedTree"])[i]); } } } } Thanks, Greg

  • MVC: model of type Nullable<T>

    - by Fyodor Soikin
    I have a partial view that inherits from ViewUserControl<Guid?> - i.e. it's model is of type Nullable<Guid>. Very simple view, nothing special, but that's not the point. Somewhere else, I do Html.RenderPartial( "MyView", someGuid ), where someGuid is of type Nullable<Guid>. Everything's perfectly legal, should work OK, right? But here's the gotcha: the second argument of Html.RenderPartial is of type object, and therefore, Nullable<Guid> being a value type, it must be boxed. But nullable types are somehow special in the CLR, so that when you box one of those, you actually get either a boxed value of type T (Nullable's argument), or a null if the nullable didn't have a value to begin with. And that last case is actually interesting. Turns out, sometimes, I do have a situation when someGuid.HasValue == false. And in those cases, I effectively get a call Html.RenderPartial( "MyView", null ). And what does the HtmlHelper do when the model is null? Believe it or not, it just goes ahead and takes the parent view's model. Regardless of it's type. So, naturally, in those cases, I get an exception saying: "The model item passed into the dictionary is of type 'Parent.View.Model.Type', but this dictionary requires a model item of type 'System.Guid?'" So the question is: how do I make MVC correctly pass new Nullable<Guid> { HasValue = false } instead of trying to grab the parent's model? Note: I did consider wrapping my Guid? in an object of another type, specifically created for this occasion, but this seems completely ridiculous. Don't want to do that as long as there's another way. Note 2: now that I've wrote all this, I've realized that the question may be reduced to how to pass a null for model without ending up with parent's model?

  • Cyclic References and WCF

    - by Kunal
    I have generated my POCO entities using POCO Generator, I have more than 150+ tables in my database. I am sharing POCO entities all across the application layers including the client. I have disabled both LazyLoading and ProxyCreation in my context.I am using WCF on top of my data access and business layer. Now, When I return a poco entity to my client, I get an error saying "Underlying connection was closed" I enabled WCF tracing and found the exact error : Contains cycles and cannot be serialized if reference tracking is disabled. I Looked at MSDN and found solutions like setting IsReference=true in the DataContract method atttribute but I am not decorating my POCO classes with DataContracts and I assume there is no need of it as well. I won't be calling that as a POCO if I decorate a class with DataContract attribute Then, I found solutions like applying custom attribute [CyclicReferenceAware] over my ServiceContracts.That did work but I wanted to throw this question to community to see how other people managed this and also why Microsoft didn't give built in support for figuring out cyclic references while serializing POCO classes

  • Appending data into Listview control

    - by strakastroukas
    In my webpage i use the following in order filling the listview control <asp:ListView ID="ListView1" runat="server"> <layouttemplate> <asp:PlaceHolder id="itemPlaceholder" runat="server" /></layouttemplate> <ItemTemplate> <tr> <td><asp:Label ID="Label1" runat="server" Text = '<%# DataBinder.Eval(Container.DataItem, "Ans1") %>' Visible = '<%# DataBinder.Eval(Container.DataItem, "Ans1Visible") %>'></asp:Label> <br /> <asp:Label ID="Label2" runat="server" Text = '<%# DataBinder.Eval(Container.DataItem, "Ans2") %>' Visible = '<%# DataBinder.Eval(Container.DataItem, "Ans2Visible") %>'></asp:Label> <br /> <asp:Label ID="Label3" runat="server" Text = '<%# DataBinder.Eval(Container.DataItem, "Ans3") %>' Visible = '<%# DataBinder.Eval(Container.DataItem, "Ans3Visible") %>'></asp:Label> <br /> <asp:Label ID="Label4" runat="server" Text = '<%# DataBinder.Eval(Container.DataItem, "Ans4") %>' Visible = '<%# DataBinder.Eval(Container.DataItem, "Ans4Visible") %>'></asp:Label> <br /> <asp:Label ID="Label5" runat="server" Text = '<%# DataBinder.Eval(Container.DataItem, "Ans5") %>' Visible = '<%# DataBinder.Eval(Container.DataItem, "Ans5Visible") %>'></asp:Label> <br /> <asp:Label ID="Label6" runat="server" Text = '<%# DataBinder.Eval(Container.DataItem, "Ans6") %>' Visible = '<%# DataBinder.Eval(Container.DataItem, "Ans6Visible") %>'></asp:Label> </td> </tr> </ItemTemplate> </asp:ListView> Now i would like to add numbers to the labels before they are rendered. For example currently the data displayed are like Tennis Football Basketball Nfl Nba Polo and the output i would like to have is 1. Tennis 2. Football 3. Basketball 4. Nfl 5. Nba 6. Polo Could i use ListView1_ItemCreated or the ListView1_ItemDataBound event to achieve this? If that is true, could you point me a place to start?

  • UAC need for console application

    - by Daok
    I have a console application that require to use some code that need administrator level. I have read that I need to add a Manifest file myprogram.exe.manifest that look like that : <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3"> <security> <requestedPrivileges> <requestedExecutionLevel level="requireAdministrator"> </requestedPrivileges> </security> </trustInfo> </assembly> But it still doesn't raise the UAC (in the console or in debugging in VS). How can I solve this issue? Update I am able to make it work if I run the solution in Administrator or when I run the /bin/*.exe in Administrator. I am still wondering if it's possible to have something that will pop when the application start instead of explicitly right clickRun as Administrator?

  • Use fileupload as template field in a details view

  • Entity Relationship Multiple 1:1's

    - by Evan
    I have an application where I have a generic object (table) called Hull. Each hull in the table is unique. I have another object that has three hulls, but they are specifically the Port_Hull, Center_Hull and Starboard_Hull. Rather than create a One to Many relationship, I was trying to create a one to one relationship for each one, but this results in numerous errors unless I make the relationship from Hull to Vessel one to many (which it is not). Any idea how I go about this, or should I abandon the concept and make the vessel to hull relationship one to many and deal with lists that always have three entries? p.s. Using uniqueidentifiers as many users can be adding records while disconnected. Hull Table HullID uniqueidentifier (primary key) plus bunch of hull data fields Vessel Table VesselID uniqueidentifier (primary key) MainHullID uniqueidentifier (tried as key and non-key) PortHullID uniqueidentifier StarboardHullID uniqueidentifier plus bunch of Vessel data fields

  • How do I get many, but not all, property values from View to Presenter in WebFormsMvp?

    - by andrej351
    Hey there, What is the best way to get a number of property values of a business object from the View to the Presenter in a WebFormsMvp page? Here is what i propose: The scenario is, I have a business object called Quote which i would like to load form the database, edit and then save. The Quote class has heaps of properties on it. The form is concerned with about 20 of these properties. I have existing methods to load/save a Quote object to/from the database. I now need to wire this all together. So, in the View_Load handler on my presenter i intend to do something like this: public void View_Load(object sender, EventArgs e) { View.Model.Quote = quoteService.Read(quoteId); } And then bind all my controls as follows: <asp:TextBox ID="TotalPriceTextBox" runat="server" Text="<%# Model.Quote.TotalPrice %>" /> All good, the data is on the screen. The user then makes a bunch of changes and hits a "Submit" button. Here is where I'm unsure. I create a class called QuoteEventArgs exposing the 20 properties the form is able to edit. When the View raises the Submit button's event, I set these properties to the values of the controls in the code behind. Then raise the event for the presenter to respond to. The presenter re-loads the Quote object from the database, sets all the properties and saves it to the database. Is this the right way to do this? If not, what is? Cheers, Andrej.

  • Nullables? Detecting them

    - by Aren B
    Ok, im still a bit new to using nullable types. I'm writing a reflecting object walker for a project of mine, im getting to the point where im setting the value of a reflected property with the value i've retrieved from a reflected property. The value i've retrieved is still in object form, and it dawned on me, since i want my object walker to return null when it can't find something, (I thought about throwing an exception, but i want this to soft-fail when something's wrong). Anyway, some of the values im setting/getting are decimal bool etc... so it dawned on me that i should just NOT set a non-nullable value, but I realized I straight up don't know how to tell decimal from decimal? Is it enough to key on if the Type of the property im setting is inherited from ValueType?

  • Workflow 4.0 code activities calling other activites (persist, delay etc)

    - by Lygpt
    I have a bunch of Workflow foundation 4.0 RC code activities that consume web services and talk to databases that I want to add some error handling in. I would really like to be able to attempt to call my web service / db, catch any faults such as a communication failure and then retry the same operation in 1 hours time (after I have logged the exception). Is there a way of doing something like this? protected override void Execute(CodeActivityContext context) { Persist(); // I would like to invoke the persist activity like this if (!AttemptServiceCall()) { // I would like to invoke a delay activity like this Delay(new TimeSpan(0, 30, 0)); // wait 30 mins before trying again Execute(context); // call this activity again } } private bool AttemptServiceCall() { bool serviceCallSuccessful = true; try { myService.InvokeSomeMethod(); } catch (CommunicationException ex) { myEventLogger.Log(ex); serviceCallSuccessful = false; } return serviceCallSuccessful; }
