View 2 RepliesWeb Forms :: Changing Custom User Control And Event Handling
Jul 29, 2010I have a custom ascx user control on my page that includes a dropdownlist. There is an onSelectedIndexChanged event handler that is connected to this dropdownlist. The first time the user selects a value, the page does a postback and the logic executes correctly. However, if the user then goes to change their selection, the event handler does not get triggered.
View 3 RepliesForms Data Controls :: Handling Events From A User Control Inside A GridView?
Jun 4, 2010I have a user control called ucTriStateButton. It raises an event when it is clicked, called TriStateButtonClicked. If I put this user control on a page, it works fine. Here is the declaration on the .aspx page:
[Code]....
When the button is clicked the method tsbTest_TriStateButtonClicked executes correctly.
The problem is when I put the user control in template field of a GridView.
[Code]....
There is no way to hook the event handler to the control in Page_Load because I cannot get a reference to tsbMorning. So I did it in the RowDataBound event handler of the GridView, where I also do a bunch of other row-specific stuff. Although this builds and runs, the event is never actually subscribed to and so never gets fired.
So the question is - how can I handle an event from many instances of the same user control within a GridView? I am calling the same bit of code regardless of which user control is actually clicked. I only need to know that one was clicked.

View 9 RepliesMVC :: Handling Unauthorized Page User Requests By Displaying A NoAccess Page?
Apr 12, 2010I have implemented a custom ErrorController with NoAccess Action returning the View "~/Error/NoAccess" (not inside the Shared folder).

C# - Handling RequiredFieldValidator Inside Of A User Control?
Jan 28, 2011I have a User Control which consists of a TextBox with a few extras, but for purposes of this example just assuming it's a plain TextBox will be sufficient. I am calling this User Control from a Web Form and would like to be able to use a RequiredFieldValidator that basically would function the same as if I used it on a TextBox on the web form. How do I configure my User Control to handle this?
EDIT:

<asp:TextBox runat="server" ID="myControlTB">
DatePicker.ascx.cs
[ValidationProperty("Text")]

Handling Dynamic User Control With JQuery
Mar 15, 2011I have a user control which I am dynamically loading in my page_load event via a method (see below). The user control contains a gridview and a label. A key piece of information has to do with how to get around the convenient feature of gridviews not rendering when their datasource is empty. In my user control I add some hidden rows so that the grids will render and the user can see just the headers (if the situation calls for it).
The nomControl is an asp:Panel on the parent page which will hold the user controls. The dsRefinedProductsNomInfo is a strongly typed dataset.
[code]....
how I should be handling my events so that my rendered grid is up to date and not showing these hidden rows. I have a feeling I am just doing things in the wrong place/order but this is my first real swim in the deep end of the asp.net pool.
Exception Handling From Private Class In User Control?
Apr 2, 2010I am part of a team that is developing a SharePoint web part. My task is to create a user control which will ultimately be wrapped in another class for presentation in a web part. Because of these requirements, I must fit all of my code in a single user control.To organize my code in the code-behind, I created a few private classes for the different objects which are represented in the database. I want to add some exception handling whereby if some sort of DB exception is thrown I can update a message on the page informing the user of the problem.
My problem is that the page-level controls are inaccessible from the private class where I'm issuing the query, so even if I catch the exception I have no way of directly accessing a Label control to populate the error. I tried to create a baseclass with an EventHandler defined, but when I throw events from the private class I'm not able to catch them for whatever reason. I'm far from an OOP expert Here is a snippet:
ASP Code:
using System;
using System.Collections;

Web Forms :: Nested User Controls - Error Handling
Jun 25, 2010I've got a .aspx page which loads a user control using the LoadControl(string virtualPath) method. The loaded control contains references to several other user controls (i will call "modules"). If such a module contains an unhandled coding error which isn't catched at compile time (e.g. division by zero), no helpful error is thrown. The .aspx page just gets an error from the LoadControl method that the control to load cannot be found (404), but in fact it contains a faulty module.
Is it possible to get the error of the module from within the .aspx page for better troubleshooting? Can I get information about, that (in this example) there is a division by zero error in module (nested user control) xy?
