Web Forms :: Event Handlers Not Triggering Any Longer?

Sep 14, 2010

I've been working on a web form that has lost it's ability to respond to most event handlers, though code that I write in Page_Load still fires. No button click or text changed events will fire. This has been working for months, and suddenly stopped. I did a windiff comparison to an older version of the webform, and don't see anything suspicious.

C# - When To Fire A Custom Control Event

Jan 21, 2010

I am creating a custom control. Let's say I'm reinventing the wheel and creating a custom Button control that derives from the UserControl class(only for example)

Well, it of course has a Click event handler. Now my problem is, when do I call this event handler? I know it happens sometime between the Pages OnLoad and OnLoadComplete, but I'm not quite sure what event I can hookup to so that the Click event is raised at the same time as other control events.

Adding Event To Custom Control?

Jul 10, 2010

I am extending the TextBox class to include CustomValidator along with the TextBox. I have created properties like CSSClass for ErrorMessage, CustomErrormessage for ErrorMessage on failure. But I am not sure how to get server side validation method in the form of tag. Example:

<asp:CustomValidator runat="server" id="custPrimeCheck"
ControlToValidate="txtPrimeNumber"
OnServerValidate="PrimeNumberCheck"
ErrorMessage="Invalid Prime Number" />

PrimeNumberCheck is the method name which is passed as parameter, same way I want to pass method in my custom TextBox for CustomValidator to run on server side.

Web Forms :: Changing Custom User Control And Event Handling

Jul 29, 2010

I 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.

Force An Event Handler To Fire For A Custom Control On Every Postback?

Feb 11, 2011

I've created a UserControl that is dynamically placed onto my page during the Init event. It populates and works great, but I'm left scratching my head at how to retrieve data from it during a postback.

It's effectively a multipick combobox that is manipulated entirely using clientside JavaScript (I'm using jQuery heavily). Inside the control container element, I render an empty DIV element that contains all of the selected items. As the user selects items, I generate DIVs within that container DIV that includes some markup. Of interest to me on the server side are the contents of a couple of INPUT fields.

After selecting an item, the rendered HTML looks something like:

[code]....

I may be completely off track and this may actually be impossible (or a stupid idea). The only alternative I can think of is to emit actual ASP.NET controls and hook the built-in event handlers.

C# - How To Handle The Click Event Of A Button In A Custom ITemplate Control

Feb 28, 2011

I've created a custom control in ASP.NET for showing a pop-up message box. In my MessageBox class, I have a Content property as ITemplate like the following:

[PersistenceMode(PersistenceMode.InnerProperty)]
[TemplateContainer(typeof(MessageBoxContent))]
[TemplateInstance(TemplateInstance.Single)]
public ITemplate Content { get; set; }

I used my custom control in my page like this:

<cc1:MessageBox ID="MessageBox1" runat="server">
<Content>
<asp:Button Text="Save" runat="server" ID="B_Save" />
</Content>
</cc1:MessageBox>

Even I set the the Content property's TemplateInstance to Single, I still can't have access to the Button control.

All I want to do is to handle the click event of the button. When I assign an event handler to the button control and run the project, it throws a NullReferenceException.

Custom Server Controls :: Click Event Not Firing In Rendered Control

Apr 14, 2010

I have a custom control that renders a button. I'm trying to attach a server click event but it isn't firing. My code is:

protected override void CreateChildControls()
{
btnRangeGo = new Button();
btnRangeGo.CssClass = "divSearchGo";
btnRangeGo.Text = Resources.CORE_Resource.S0C29; // Go
btnRangeGo.Click += new EventHandler(btnRangeGo_Click);
// Tried with no luck:
// this.Controls.Add(btnRangeGo); // Needed so OnClick gets registered
// Page.Controls.Add(btnRangeGo); // Needed so OnClick gets registered
}

private void btnRangeGo_Click(object sender, EventArgs e)
{
int i = 1;
}
OnRender:
btnRangeGo.RenderControl(writer);

Custom Server Controls :: Trigger Click Event In Composite Control?

May 10, 2010

My CompositeControl creates dinamically several RadioButtonLists according to the DataSource information. These controls are added to the Controls list and rendered in CreateChildControls event.

I need to create a LinkButton that clear a specific RadioButtonList selection and do a postback, to load the DataSource information again (some selections changes the data that need to be loaded from the database). For each RadioButtonList, I've put a LinkButton and assigned the Click Event to a method inside the same CompositeControl, to do the RadioButtonList cleaning.

Unfortunatelly, the LinkButton doesn't trigger the Click Event. In HTML code, the link has the "onclick" attribute setted with the asp.net event, but when clicked, nothing happens.

Security :: Login Control - Remember Me Code No Longer Works

Jan 15, 2011

This code worked until I published a recent set of changes to the web site. It's very strange behavior that I am having trouble debugging. Basically, I implemented some custom code to allow custom configuration of login timeouts from an app settings variable.

When debugging the application, if I click remember me or not, Login works perfectly. Once I post the updated code to the live server, login only works if I have the Remember Me option unchecked. If I check remember me, it does not log in, and it cycles the user back to the default web page. If I access the site from IE on the live server, remember me works correctly.

Here is the Logged_In event handler code:

When Change CombineScripts Property To True Control Extender, It Cannot Work Longer

Jun 3, 2010

I have an ASP.NET 3.5 web application in which i am using the ToolkitScriptManager as below:

<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" EnablePageMethods="true" ScriptMode="Release"
LoadScriptsBeforeUI="false" runat="server" CombineScripts="false">
<CompositeScript>
<Scripts>
<asp:ScriptReference Path="~/JavaScript/jquery-1.4.1.min.js" />
<asp:ScriptReference Path="~/JavaScript/Validators.js" />
</Scripts>
</CompositeScript>
</ajaxToolkit:ToolkitScriptManager>

This works fine but from a performance standpoint this is not good as the pages are making a lot of requests to the webresources.axd and scriptresource.axd files. When I changed the CombineScripts property to true my ASP.NET AJAX control extenders are no longer working. What is the reason for this weired behavior and is there a fix for this?

My problem is how to create a link on the selecond level rows that posts back with custom data.

Custom Server Controls :: Button Triggering An Event In A Custom Webcontrol?

Nov 16, 2010

I built a webcontrol showing a complex user interface with a lot of javascript. Basically my webcontrol is similar to : [URL]

Now that most the user interface is working properly, I'm stuck with the following issue: I want to add a button (html button tag) which has to trigger an event. I have been able to declare the event, the event args, the delegate,etc. The page using my control may assign a handler and that handler is called correctly when I explicitely call OnServerControlClick (The name I gave to the event). I cannot make the link between the button in the user interface and the event in the webcontrol source code. When the button is clicked, I get an error message saying a dangerous Request.Form value has been detected.
