Web Forms :: UserControl's Load Event Is Not Fired?
Mar 16, 2011I have a Page, that has UserControl1.
UserControl1 has UserControl2.
When the page loads UserControl2's Load event is not fired at all.
I have a Page, that has UserControl1.
UserControl1 has UserControl2.
When the page loads UserControl2's Load event is not fired at all.
I have a confusion regarding ajax call.when an ajax call is done why is it so that a page load event is fired when its not a ful page request.
My understanding is that a page load event should not be called on an asynchronous postback.
Can any1 explain me why this is happening?
here is the code:
aspx page:
[Code]....
aspx.cs page:
[Code]....
i have develop a custom control as shown below
[Code]....
[Code]....
Now in page load event i am trying to a access textbox (txtData) of my custome control as shown below
[Code]....
[Code]....
A breakpoint is set on FillForm() and this method is called two times but I can't explain myself why this happens. I have client side javascript code, when the form is being send, the onsubmit method is also called twice... Where do I have to search?! Is it a (known) bug? Think I could get it to work with this Thread: [URL] But why is the event fired within the onblur-event when it's fired anyway??
I need to load a web user control dynamically.
Looking at [URL] it states that the page lifecycle events are not fired.
I thought I might be able to raise the events through reflection. I cannot figure how to fire the events, am I missing something?
I have a DetailsView control bound to an ObjectDataSource within a User Control (.ascx). It appears that the DetailsView.OnDataBound event is being fired on every page load or postback.
I do not see this behavior with a similiar DetailsView directly placed on an aspx page.
I have one Button (Refresh Button), One ComboBox (containing DEV and UAT as its items) and a GridView on my asp page.
I am filling up my Grid with values from database on the ComboBox's 'TextChanged' event and Buttons's 'Click' event.
First time when page is loaded, there is no information in the grid, but when i choose DEV/UAT from the ComboBox 'TextChanged' event is fired, the grid is filled with the relevant data. That is what i want.
When i click the Refresh Button to refresh the data again, first comboBox's 'TextChanged' event and then 'btn_Click' event is fired.
I want then when a button id pressed only 'Click' event to be fired and not the ComboBox's 'TextChanged' event.
I have page having two user controls. Now I have a requirement for which i have to trigger one user control event from another user control.

Here I have gridview control with checkbox for selection of one or two records. Have one button and when clicking this , i need to get the selected records values and assign this values to the textbox which is in usercontrol1.
I have a simple Insert Query and placed it at Page Load of my page, each time the page is loaded, it runs this INSERT COMMAND twice and inserts two rows to DATABASE.
I have also set the AutoEvenWireup to FALSE, but did not solve my problem.

There is a bug in jQuery 1.4.2 that makes change event on select-element getting fired twice when using both DOM-event and a jQuery event, and this only on IE7/8.Here is the test code:
<html>
<head>
<script src="http://code.jquery.com/jquery-1.4.2.js" type="text/javascript"></script>[code].....
This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem.
