  • asp.net custom templated datalist - throws argument out of range (index) on button press

    - by MrTortoise
    I have a class BaseTemplate public abstract class BaseTemplate : ITemplate This adds the controls, and provides abstract methods to implement in the inheriting class. The inheriting class then adds its html according to its data source and manages the data binding. this all works fine - I get the control appearing with properly parsed html. the problem is that the base class adds controls into the template that have their own CommandName arguments ... the idea is that the class that implements the custom templated dataList will provide the logic of setting the Selected and Edit Indexes. This class also manages the data binding etc. It sets all of the templates ont he datalist in the Init method (which was another cause of this exception). the exception gets throw when i hit one of these buttons .. but after the ItemCommand event is being processed. The stack trace does not include any references to my methods or objects which is why i am so stuck. The Exception Details Exception Details: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

  • response.write only working IE for ASP.NET

    - by slowlycooked
    I'm using uploadify (http://www.uploadify.com/) to upload video to my site then convert them into *.flv using ffmpeg and play preview. But it dosen't fully working with firefox, chrome or safari. uploadify provides a onComplete interface, so when the script (.ashx, .php) used on your site for saving uploaded files. you can use response.write("blabla") or (echo "blabla") to invoke the javascript function that registed as OnComplete. i have test with few video files like avi, mpg, mp4, they are less then 50mb,and they all worked with all 4 browsers. However, when i was trying to upload a 75mb mp4 file, it worked in IE, but didn't working in other three. I can see the .flv file has been create in the upload folder, i can see debug messsage output after response.write("blabla"), but the javascript function was not invoked. i.e. the preview didn't play. anyone knows why? is there a timeout or something on response.write so after a period of time it wont work? e.g. 75mb file took longer time to convert than other smaller size file i tried. thansk

  • Reading an embedded file from an ASP.NET Custom Server Control an rendering it

    - by Andreas Grech
    I currently have a file "abc.htm" in my Custom Server Control Project and it's Build Action is set to Embedded Resource. Now in the RenderContents(HtmlTextWriter output) method, I need to read that file and render it on the website. I am trying the following but it's to no avail: protected override void RenderContents(HtmlTextWriter output) { var providersURL = Page.ClientScript.GetWebResourceUrl(typeof (OpenIDSel), "OpenIDSelector.Providers.htm"); var fi = new FileInfo(providersURL); // <- exception here //the remaining code is to possibly render the file } This is an example of how the providersURL is: /WebResource.axd?d=kyU2OiYu6lwshLH4pRUCUmG-pzI4xDC1ii9u032IPWwUzMsFzFHzL3veInwslz8Y0&t=634056587753507131 FileInfo is throwing System.ArgumentException: Illegal characters in path.

  • Screen information while Windows system is locked (.NET)

    - by Matt
    We have a nightly process that updates applications on a user's pc, and that requires bringing the application down and back up again (not looking to get into changing that process). The problem is that we are building a Windows AppBar on launch which requires a valid screen, and when the system is locked there isn't one in the Screen class. So none of the visual effects are enabled and it shows up real ugly. The only way we currently have around this is to detect a locked screen and just spin and wait until the user unlocks the desktop, then continue launching. Leaving it down isn't an option, as this is a key part of our user's workflow, and they expect it to be up and running if they left it that way the night before. Any ideas?? I can't seem to find the display information anywhere, but it has to be stored off someplace, since the user is still logged in. The contents of the Screen.AllScreens array: ** When Locked: Device Name : DISPLAY Primary : True Bits Per Pixel : 0 Bounds : {X=-1280,Y=0,Width=2560,Height=1024} Working Area : {X=0,Y=0,Width=1280,Height=1024} ** When Unlocked: Device Name : \\.\DISPLAY1 Primary : True Bits Per Pixel : 32 Bounds : {X=0,Y=0,Width=1280,Height=1024} Working Area : {X=0,Y=0,Width=1280,Height=994} Device Name : \\.\DISPLAY2 Primary : False Bits Per Pixel : 32 Bounds : {X=-1280,Y=0,Width=1280,Height=1024} Working Area : {X=-1280,Y=0,Width=1280,Height=964}

  • Linq ChangeConflictException (ASP.NET MVC) - occurs when submitting DataContext changes

    - by Alex
    System.Data.Linq.ChangeConflictException: 2 of X updates failed. at System.Data.Linq.ChangeProcessor.SubmitChanges(ConflictMode failureMode) at System.Data.Linq.DataContext.SubmitChanges(ConflictMode failureMode) at PROJECT.Controllers.HomeController.ClickProc(Int32 id, String code, String n) This is what I get very often. This action is done thousands of times a day, and I get this exception about once every 5 seconds. From what I understand it happens when something changes in the database in the period between creating DataContext and updating it. Am I right? What's the problem here and how can I fix it?

  • ASP.NET Session and target blank

    - by Lennart
    Hi I have seen a few posts regarding Session and using target blank to open a new page. But I still don´t get it. Im working with an application which opens from a link on an Intranet site. I guess it uses target blank to get it in a new window. (I don´t have the source). If both windows are closed (My application and the Intranet site) it seems like the Session is destroyed. I need that to happen when my application is closed. (ie, still leaving the Intranet site open). If I use the site in my testenvironment without opening it from a page with target blank, it seems like I get the expected behaviour. Web.config has: pages enableSessionState="true" Thanks

  • Generic Type Parameter constraints in C# .NET

    - by activwerx
    Consider the following Generic class: public class Custom<T> where T : string { } This produces the following error: 'string' is not a valid constraint. A type used as a constraint must be an interface, a non-sealed class or a type parameter. Is there another way to constrain which types my generic class can use? Also, can I constrain to multiple types? E.G. T can only be string, int or byte

  • ASP.net MVC Linq-To-SQL Many-To-Many Field Binding

    - by user336858
    Hi there, The short version of this question is "Is there a way to gracefully handle database insertion for an object that has a many-to-many field that has been set up in a partial class?" Apologies if it's been asked before. Example Suppose I have a typical MVC setup with the tables: Posts {PostID, ...} Categories {CategoryID, ...} A post can have more than one category, and a category can identify more than one post. Thus suppose further that I need an extra table: PostCategories {PostID, CategoryID, ...} This handles the many-to-many relationship between posts and categories. As far as I know, there's no way to do this in Linq-to-SQL right now so I have to shoehorn it in by adding a partial Post class to the project to add that functionality. Something like: public partial class Post { public IEnumerable<Category> Categories{ get { ... } set { ... } } } So I can now create a "Create" view that automatically populates a "Categories" UI item. This is where the trouble starts. So here's my question: How do you get automatic object model binding to work cleanly with an object that has a many-to-many relationship to control? The workaround that makes many-to-many relationships possible relies on the Post object having a PostID in order to be associated with CategoryID(s), which is only issued after the Post object has been submitted for validation and insertion. Bit of a Catch22 here. Any terminology, links, or tips you can provide would be tremendously helpful!

  • ASP.NET: "Object Required" when repeating LinkButtons in an UpdatePanel

    - by MStodd
    I have an UpdatePanel which has a Repeater repeating LinkButtons. When I click a LinkButton, the page does a partial postback, then I get a javascript error: "Object required". I tried debugging the javascript, but couldn't get a call stack. If I remove the UpdatePanel, the LinkButtons do a full postback, and they disappear from the page. How can I get this UpdatePanel to work? <ajax:UpdatePanel ID="wrapperUpdatePanel" runat="server" UpdateMode="Always"> <ContentTemplate> <asp:Repeater ID="endpointRepeater" runat="server" OnItemDataBound="EndpointDataBound"> <HeaderTemplate> <div class="sideTabs"> <ul> </HeaderTemplate> <ItemTemplate> <li> <asp:LinkButton ID="endpointLink" runat="server" OnClick="EndpointSelected" /> </li> </ItemTemplate> <FooterTemplate> </ul> </div> </FooterTemplate> </asp:Repeater> </ContentTemplate> </ajax:UpdatePanel> binding code: protected void Page_Load(object sender, EventArgs e) { if (!this.IsPostBack) { this.SelectedEndpoint = Factory.Get<IEndpoint>(Enums.EndPoints.Marketing); } IEndpointCollection col = EndpointCollection.GetActivelySubscribingEndpointsForPart(this.Item); if (this.Item.IsGdsnItem) col.Add(Factory.Get<IEndpoint>(Enums.EndPoints.Gdsn)); if (col.Count > 0) col.Insert(0, Factory.Get<IEndpoint>(Enums.EndPoints.Marketing)); this.endpointRepeater.DataSource = col; this.endpointRepeater.DataBind(); if (this.endpointRepeater.Items.Count > 0) { LinkButton lb = this.endpointRepeater.Items[0].FindControl("endpointLink") as LinkButton; this.EndpointSelected(lb, new EventArgs()); } } thanks, mark

  • VB.NET template instance - passing a variable data type

    - by FerretallicA
    As the title suggests, I'm tyring to pass a variable data type to a template class. Something like this: frmExample = New LookupForm(Of Models.MyClass) 'Works fine Dim SelectedType As Type = InstanceOfMyClass.GetType() 'Works fine repoGeneric = New Repositories.Repository(Of SelectedType) 'Ba-bow! repoGeneric = New Repositories.Repository(Of InstanceOfMyClass.GetType()) 'Ba-bow! I'm assuming it's something to do with the template being processed at compile time but even if I'm off the mark there, it wouldn't solve my problem anyway. I can't find any relevant information on using Reflection to instance template classes either. (How) can I create an instance of a dynamically typed repository at runtime?

  • Controls.remove() method not working in asp.net

    - by user279521
    I have a web app where the user can create dynamic textboxes at run time. When the user clicks SUBMIT, the form sends data to the database and I want remove the dynamic controls. The controls are created in the following code: Table tb = new Table(); tb.ID = "tbl"; for (i = 0; i < myCount; i += 1) { TableRow tr = new TableRow(); TextBox txtEmplName = new TextBox(); TextBox txtEmplEmail = new TextBox(); TextBox txtEmplPhone = new TextBox(); TextBox txtEmplPosition = new TextBox(); TextBox txtEmplOfficeID = new TextBox(); txtEmplName.ID = "txtEmplName" + i.ToString(); txtEmplEmail.ID = "txtEmplEmail" + i.ToString(); txtEmplPhone.ID = "txtEmplPhone" + i.ToString(); txtEmplPosition.ID = "txtEmplPosition" + i.ToString(); txtEmplOfficeID.ID = "txtEmplOfficeID" + i.ToString(); tr.Cells.Add(tc); tb.Rows.Add(tr); } Panel1.Controls.Add(tb); The Remove section of the code is: Table t = (Table)Page.FindControl("Panel1").FindControl("tbl"); foreach (TableRow tr in t.Rows) { for (i = 1; i < myCount; i += 1) { string txtEmplName = "txtEmplName" + i; tr.Controls.Remove(t.FindControl(txtEmplName)); string txtEmplEmail = "txtEmplEmail" + i; tr.Controls.Remove(t.FindControl(txtEmplEmail)); string txtEmplPhone = "txtEmplPhone" + i; tr.Controls.Remove(t.FindControl(txtEmplPhone)); string txtEmplPosition = "txtEmplPosition" + i; tr.Controls.Remove(t.FindControl(txtEmplPosition)); string txtEmplOfficeID = "txtEmplOfficeID" + i; tr.Controls.Remove(t.FindControl(txtEmplOfficeID)); } } However, the textboxes are still visible. Any ideas?

  • WinForms / .Net interactive world map - how?

    - by FerretallicA
    In a CD collection program, I have each artist's country of origin stored in the main database and want to display a map of the world which: Colour-codes each country depending on the number of CDs by artists in that country Allows clicking on each country to filter a list of CDs to only ones by artists in that country This is a heavily simplified version of what I'm trying to do, but if I can at least get this far the rest should be easy enough to figure out. So far the closest thing I've found to what I'm trying to do is here: http://www.synergetechsolutions.com/blog/analytics-world-map-control Ideally I don't want to be embedding Flash in my program though, and the only other solutions I've found all involve SVG which I haven't managed to get working in practice outside of a web browser control (and I DEFINITELY don't want to be embedding a browser in the forms). Something in pure managed code and either GDI+ or WPF would be preferable. Are there any existing components that would get me started, or can anyone suggest how to approach it from scratch?

  • ASP.NET client side validation with dataannotations - javascript minimumlength zero

    - by Kordonme
    Hi! I'm doing client side validation on a project I'm working on. Everything works, except for the minimumlength property of the StringLength attribute (it works when submitting and a serverside validation is done): [StringLength(50, MinimumLength = 6)] The javascript generated by Html.EnableClientValication(); is the following: // snip {"FieldName":"User.Password","ReplaceValidationMessageContents":true,"ValidationMessageId":"User_Password_validationMessage","ValidationRules":[{"ErrorMessage":"The field Password must be a string with a minimum length of 6 and a maximum length of 50.","ValidationParameters":{"minimumLength":0,"maximumLength":50},"ValidationType":"stringLength"}]}],"FormId":"form0","ReplaceValidationSummary":false}) The important thing is here: {"minimumLength":0,"maximumLength":50} It produces javascript with the wrong minimumproperty. You guys have a hint? Is this a possible bug?

  • Most efficient way to update a MySQL Database on a Linux host with that of an ASP.Net Form on Window

    - by NJTechGuy
    My kind webhost (1and1) royally asked me to go elsewhere to do something like this. I have 2 sites. One of them was developed by a .Net programmer. Now I am contracted to implement a PHP site and fetch data from the .Net site. There is an ASP.Net form that a customer fills and when they hit submit, the data gets stored in SQL Server DB. How do I also store the same data in MySQL parallelly? I cannot directly use some database connectors with ASP.Net since MySQL connectivity is not supported on 1and1 Windows hosting (biz account, no less!). What I thought of is to publish an RSS feed of entries in ASP.Net site and routinely scrape that data into MySQL on Linux host. It is an overkill, I know. Not efficient. I thought I would pick the best brains on SOF to get a different, efficient opinion. Thanks in advance guys...
