  • Help with Exception Handling in ASP.NET C# Application

    - by Shrewd Demon
    hi, yesterday i posted a question regarding the Exception Handling technique, but i did'nt quite get a precise answer, partly because my question must not have been precise. So i will ask it more precisely. There is a method in my BLL for authenticating user. If a user is authenticated it returns me the instance of the User class which i store in the session object for further references. the method looks something like this... public static UsersEnt LoadUserInfo(string email) { SqlDataReader reader = null; UsersEnt user = null; using (ConnectionManager cm = new ConnectionManager()) { SqlParameter[] parameters = new SqlParameter[1]; parameters[0] = new SqlParameter("@Email", email); try { reader = SQLHelper.ExecuteReader(cm.Connection, "sp_LoadUserInfo", parameters); } catch (SqlException ex) { //this gives me a error object } if (reader.Read()) user = new UsersDF(reader); } return user; } now my problem is suppose if the SP does not exist, then it will throw me an error or any other SQLException for that matter. Since this method is being called from my aspx.cs page i want to return some meaning full message as to what could have gone wrong so that the user understands that there was some problem and that he/she should retry logging-in again. but i can't because the method returns an instance of the User class, so how can i return a message instead ?? i hope i made it clear ! thank you.

  • ASP.NET AJAX UpdatePanel problem

    - by Velika
    I'll try and be concise: 1) I have a dropdownlist with Autopostback set to TRUE 2) I have an UpdatePanel that contains a Label. 3) When the downdownlist selection is changed, I want to update the label. Problem: Focus is lost on the dropdownlist, forcing the user to click on the dropdownlist to reset focus back to the control. My "solution": In the DropDownList_SelectionChanged event, set focus back to the drop down list: dropdownlist1.focus() Problem: While this works great in IE, Firefox and Chrome change the scroll position such that the control which was assigned focus is positioned at the bottom on the visible portion of the browser window. This is often a very disorientating side effect. How can this be avoided so it works in FF as it does in IE?

  • ASP.net getting NT user name returns administrator?

    - by JonH
    This doesnt seem to be an issue with windows XP. But I have an end user (my boss!!!) using windows 7 64 bit... In one of our apps we are grabbing the end user user name via: HttpContext.Current.User.Identity.Name.ToString.Substring (HttpContext.Current.User.Identity.Name.ToString.IndexOf("\") + 1).ToLower For me it is returning the correct user name for instance "jhermiz". When my boss tries getting into the app, it thinks he is Administrator??? Does anyone know of any alternative or why this might be happening? The reason this is an issue is because I use that user name to pull other information... This is visual studio 2003.

  • How ASP.NET MVC passes model to the view without explicitly passing it

    - by Vlad Bezden
    Here is one of the examples that I've seen on how to do validation on Controller: [HttpPost] public ViewResult Create(MyModel response) { if (ModelState.IsValid) { return View("Thanks"); } else { return View(); } } If there are validation errors, than return View() method is called without any parameters. Obviesly you have @Html.ValidationSummary() in your View and Model has all required properties attributes. The data that was entered into the form was preserved and displayed again when the view was rendered with the validation summary. My question is how data preserved? Since it was not passed to the View like return View(response); Thanks a lot. Sincerely, Vlad

  • ASP.Net User Control Template Instantiation

    - by Chris
    Hi, I created a user control that has a template container. <cc:SearchResultItem ID="SearchResultItem1" Customer='<%# ((Customer)(((RepeaterItem)Container).DataItem)) %>' runat="server"> <NameTemplate> <%# Container.Name %> </NameTemplate> </cc:SearchResultItem> This is control is placed in a repeater which lists some customers. The customer is than bound to the user control. When the name template is instantiated in the container, the customer object is not yet available, but I need to access its name because it needs to get parsed before. protected void Page_Init(object sender, EventArgs e) { if (nameTemplate != null ) { // customer is null here, it is avaiable only after Page_Init... NameContainer container = new NameContainer(customer.Id, Parse(customer.Name)); nameTemplate.InstantiateIn(container); placeHolder.Controls.Add(container); } } Question: How can I access properties set for the user control BEFORE the template container is instantiated? Thanks in advance!

  • ASP.NET AJAX postback and jQuery

    - by Echilon
    I have a Textbox, a LinkButton and a RadioButtonList inside an UpdatePanel. When the button is clicked, the UpdatePanel shows matching items in the radiobuttonlist. This works fine, but I now need to make the same happen OnKeyDown on the TextBox. I'm trying to cancel all AJAX requests in progress but not having much luck. Firstly, on every keypress the UpdatePanel posts back, so only one letter can be changed at a time. Secondly, the textbox loses focus on postback. I need to show the list as normal, but OnKeyDown as well as when the button is pressed. This is what I have (control IDs shortened) $('#textBoxId').live('keydown', function(e) { if((e.keyCode >= 47 && e.keyCode <= 90) || e.keyCode == 13) { Sys.WebForms.PageRequestManager.getInstance().abortPostBack(); $('#buttonId').click(); $('#textBoxId').focus(); } }); Thanks for any insight.

  • GLOBAL loading inside each single button with Jquery in ajax calls of asp.net mvc

    - by Ricky
    I have the following scenario: I have a button\link with a image inside like this: <button type="submit" id="myButton" class="button"><img src="../../Content/images/check.png" id="defaultImage" /> SaveData!!!</button> We are OK here! Now what I need to do is: I want on the click that the image change for a loading element that is previously loaded in the page like this: <img id="loadingImage" src="../../Content/images/loader.gif" style="display: none;" alt="loading"/> And then when the load complete turn back the old button image, I ended with this code: function loader() { var $button = $('#myButton'); if (btnState == '1') { $button.find('img').hide(); $button.prepend($('#loadingImage')); $('#loadingImage').css({ 'display': 'inherit' }); btnState = '0'; } else { $button.find('img').hide(); $button.prepend($('#defaultImage')); $('#defaultImage').show(); btnState = '1'; } } This does the trick for ONE SINGLE button(since I pass its ID in the function) but, when I have for example a grid with a button on each line, I found inviable when managing a screen with many buttons do this for each of then. The main question is: How can I make this method general for all buttons/links on one specific class in the page? The goal is: Click a button, get the image and change it and stop(can be manual). I just don't wanna have to Hook ALL buttons.

  • ASP.NET putting dynamic controls on page in reverse messes up events

    - by Jimmy Geels
    I have this weird problem when putting textboxes on the page in reverse. The whole event system is messed up. Changing one textbox fires TextChange on all textboxes. I can fix this by putting the controls in a list first and then call add while iterating trough the list in reverse. But i just want to know why this fails. Heres some code (.net 2.0) public partial class _Default : Page { protected void Page_Load(object sender, EventArgs e) { InitFields(); } private void InitFields() { int nrFields; //We have a static textbox called nrElements, this determines the number //of fields to initialize if (int.TryParse(nrElements.Text, out nrFields)) { //Put all the dynamic fields on the screen in reverse order foreach(Control t in GetDynamicFields(nrFields)) { //Calling Controls.Add works fine //Calling Controls.AddAt messes up the events //Try changing different textboxes plhFields.Controls.AddAt(0, t); } } } private IEnumerable<Control> GetDynamicFields(int nrFields) { for (int i = 0; i < nrFields; i++) { TextBox txtBox = new TextBox(); txtBox.ID = string.Format("dynTextBox{0}", i.ToString()); txtBox.AutoPostBack = true; txtBox.TextChanged += t_TextChanged; yield return txtBox; } } private void t_TextChanged(object sender, EventArgs e) { TextBox txtBox = sender as TextBox; if (txtBox != null) txtBox.Text = txtBox.Text + "Changed "; } }

  • Use ASP.Net server control code generation from .ashx

    - by Matt Dawdy
    I'm trying to take an existing bunch of code that was previously on a full .aspx page, and do the same stuff in a .ashx handler. The code created an HtmlTable object, added rows and cells to those rows, then added that html table the .aspx's controls collection, then added it to a div that was already on the page. I am trying to keep the code in tact but instead of putting the control into a div, actually generate the html and I'll return that in a big chunk of text that can be called via AJAX client-side. HtmlTable errors out when I try to use the InnerHtml property (says it isn't supported), and when I try RenderControl, after making first a TextWriter and next an HtmlTextWriter object, I get the error that Page cannot be null. Has anyone done this before? Any suggestions?

  • Encrypting an id in an URL in ASP.NET MVC

    - by Chuck Conway
    I'm attempting to encode the encrypted id in the Url. Like this: http://www.calemadr.com/Membership/Welcome/9xCnCLIwzxzBuPEjqJFxC6XJdAZqQsIDqNrRUJoW6229IIeeL4eXl5n1cnYapg+N However, it either doesn't encode correctly and I get slashes '/' in the encryption or I receive and error from IIS: The request filtering module is configured to deny a request that contains a double escape sequence. I've tried different encodings, each fails: HttpUtility.HtmlEncode HttpUtility.UrlEncode HttpUtility.UrlPathEncode HttpUtility.UrlEncodeUnicode Update The problem was I when I encrypted a Guid and converted it to a base64 string it would contain unsafe url characters . Of course when I tried to navigate to a url containing unsafe characters IIS(7.5/ windows 7) would blow up. Url Encoding the base64 encrypted string would raise and error in IIS (The request filtering module is configured to deny a request that contains a double escape sequence.). I'm not sure how it detects double encoded strings but it did. After trying the above methods to encode the base64 encrypted string. I decided to remove the base64 encoding. However this leaves the encrypted text as a byte[]. I tried UrlEncoding the byte[], it's one of the overloads hanging off the httpUtility.Encode method. Again, while it was URL encoded, IIS did not like it and served up a "page not found." After digging around the net I came across a HexEncoding/Decoding class. Applying the Hex Encoding to the encrypted bytes did the trick. The output is url safe. On the other side, I haven't had any problems with decoding and decrypting the hex strings.

  • Setting the value of a radio button with JQuery (ASP.NET MVC)

    - by Mario
    I have 2 "lists" of (4) radio buttons {value = "0", "1", "2", "3"} in all lists. The first list needs to drive the second list (which may occur multiple times). So if an option is selected in the first list, the SAME option is selected in the second list. It sounds weird, but it has a purpose. The first list is more of a "select all" type of list, and the second list is an individual selection list(s). I have the value of the "selectall" list via JQuery: $("#selectalllist").change(function() { var str = $('input[name=selectall]:checked').val(); $(".radiolist").attr('checked', str); //This is my thinking }); The current selected value is stored in the str variable, and that is seemingly correct (I used alert to tell me what is stored, and it comes up what I expect). I just need to set the value of the next set of lists. The second line of the code I thought would set the checked value of $(".radiolist") to the stored value, but it ALWAYS set the value to the last entry (value = "3"). I'm wondering if I have the wrong attribute in the .attr('', str) call? Any thoughts?

  • Extending ASP.NET role providers

    - by Quick Joe Smith
    Because the RoleProvider interface seems to treat roles as nothing more than simple strings, I'm wondering if there is any non-hacky way to apply an optional value for a role on a per-user basis. Our current login management system implements roles as key-value pairs, where the value part is optional and usually used to clarify or limit the permissions granted by a role. For example, a role 'editor' might contain a user 'barry', but for 'barry' it will have an optional value 'raptors', which the system would interpret to mean that Barry can only edit articles filed under the 'raptors' category. I have seen elsewhere a suggestion to simply create additional delimited roles, such as 'editor.raptors' or somesuch. That's not really going to be ideal because it would bloat the number of roles greatly, and I can tell it's going to be a very hard sell to replace our current implementation (which is also very less than ideal, but has the advantage of being custom made to work with our user database). I can tell already that the concatenation method mentioned above is going to involve a lot of tedious string-splitting and partial matching. Is there a better way?

  • ASP.NET Gridview Checkbox value to DataTable

    - by Mark
    Hey all, First off, im using a checkbox to highlight a true or false value from a dataset which I want to be able to change it. Unfortunately databinding the DataTable to the GridView checkboxes doesnt work (as you probably know) as it requires it to be in "edit" mode. The way I've gotten round this is having the checkbox reading the data table value seperately rather than being databound and locked: Checked='<%# Convert.ToBoolean(Eval("myValue")) %>' So that solves checkbox values from DataTable - GridView, now I need to do the opposite having the changed checkbox values go from GridView - DataTable as it is not ready to submit it to my data source (SQL) just yet. I figure I need to run a loop through the GridView rows, thats a give'un, what I can't figure out is how to replace/update just a single value in a row of a DataTable , only the ability to add or remove an entire row by the looks of things (something I don't want to do). So can anyone offer a workaround? Or is there a way to have a databound but always editable checkbox in a gridview?

  • C# ASP.Net The type or namespace name 'Secure' does not exist in the namespace 'source_extranet'

    - by Louis Russell
    Afternoon all, I really need your help as this is a Nightmare! I was earlier having a problem with referencing a 3rd Party Dll (Here) but have overcome this problem and am now having a problem referencing my own classes! Everything seems fine at build with no errors at all but when I go to run the application it comes up with the following Compilation Error: Compiler Error Message: CS0234: The type or namespace name 'Secure' does not exist in the namespace 'source_extranet' (are you missing an assembly reference?) The line that the Error points to this line in the class: source_extranet.Secure.BackendCustomData newdata = new source_extranet.Secure.BackendCustomData(); This line of code points to a class in the same folder as the calling code class. I have scoured Google looking for an answer and haven't found anything that points me to an answer to my problem. Any help would be AMAZING!

  • Export Multiple Crystal Reports ASP.NET
