I am loading in a user control on page load and events are never firing. The user control loads fine with the correct information. it contains two dropdowns and an
calendar control. The dropdown selection changed event is never fired. I am not sure if there is something wrong while control is being rendered.

I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.
Here is what i am trying to do I have a multiview and two views in it so based on click event the link the views change
[code]....
apparently they are not firing on first try. The reason i am doing this is the two views have tables with different images to be used in building my menu.
What am i doing wrong? or why is the click event firing on second try?
I am using the following code to load user control on to ASPX Page, which under a Master Page:
[Code]....
The user control name is passed as a parameter on the URL.
Inside the user, there is a LinkButton. The link button has a simple server side code for OnClick event.
Everything is working fine on the production machine, but, on the Development machine, I can see incorrect behaviour. I have started making some development changes on the Development Machine since several months back, and it will be very difficult to find out what caused the problem.
When I click the LinkButton inside the user control, the user control is removed from the parent page, and the OnClick event of the LinkButton is not firing.
I did debug, and found out that after I click on the LinkButton inside the user control, then the Page Load events for the master page and the ASPX page are working fine, and the IsPostBack is set to true, but the OnClick event of the LinkButton is not firing.
I have a aspx page, default.aspx, with an user control in it. Inside the user control (UC 1) there is a DataGrid. When the DataGrid is loading data with ItemDataBound, I need to dynamically load another user control (UC 2) for each row in the DataGrid. UC 2 has a Button ( BTN )with an eventhandler associated with it in code behind.
User control loading is fine, and the Button, BTN, is there. However, when I click the Button, the eventhandler is not reached, not firing, even though the page does postback. I googled for this issues, and I know the dynamically loaded user controls need to be loaded every time the page is postback. In my case, it needs to be loaded each time the datagrid is doing ItemDataBound. I did it and even hook up the eventhandler with button click event each time when the user control is dynamically loaded. I set EnableViewState to true on the Page and controls.
The following is part of the code from UC 1, AcctPaymentDetail is UC 2 in the code.

And the following is UC 2 the is being loaded:

I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.

i have a page on which i dynamically add multiple datalist controls on the oninit event of my page , on postabck i again add all these datalist controls to the page on oninit event
the template for all the datalist controls is defined using the ITemplate interface, the template defined for each datalist control contains a button which has a event handler attached to onclick event.
the problem is first time i click the button on postback i add the multiple datalist controls , the event gets fired which modifies the datatable i am using to generate my datalist controls and the datalist controls with the modified data show on the page but the second time a user clicks the button inside datalist the event does not get fired.
While I am using a "Telerik" control here it shouldn't be any different I guess;
[code]....
What happens is that the control is created and rendered;
When I change value in the Combo box a Post-Back happens.
HOWEVER, the event RadComboBoxSelectedIndexChanged does not fire. Also when I am back at the page the new value is not saved; Obviously, i recreate the control every time. If I don't I get a ViewState error. Seems to me that there some ViewState management problem, but I cannot identify it...
I want to fie event calender_dayrender forcefully in dropdownlist_selectedindex .Dont know how to give parameters (sender,e).

I have a page with in a master page. This page has a user control with a text box and a button. I also have another button on the page. As the page first loads the button_click event on both the controls does not fire when clicking the buttons. I also have an event on the enter key on the text box. This event fires which causes a post back. After post back now my button_click event fire. The button_click event does not fire on the first page_load.

I have a link button which is part of my user control. Further, the control is actually added to the control dynamically. Whilst, I can see the control, and is added to the page without any visible errors, but when I click on to fire an event which on that user control nothing happens. What is even more odd, if I add a break point to event, and then click in debug mode, I can't even reach the break point!
To try and resolve this, I have tried giving the link button ids, and ensured they unique, added override using OnInit and used the createchildcontrols method, but nothing seems to work!

I have a page books.aspx that has a control named authors.ascx.
Inside the authors control there is a "select" button I want to add some kind of listener or event handler (not sure of the correct terminology) so on the parent page (books.aspx) I can respond to the "select" button being clicked.
I have to pass the authorID from the user control to the parent page.
In my authors.ascx control I just created this event:

Now I need to write the function for SelectAuthorBtnClick and I think add some kind of listener in the parent page to listen and handle the event.
I have a control which has an ImageButton which is tied to an OnClick event... Upon clicking this control, a postback is performed and the event handler is not called. AutoEventWireup is set to true, and I've double checked spelling etc.... We haven't touched this control in over a year and it has been working fine until a couple of weeks ago.
We have made changes to controls which load this control... so I'm wondering, what kind of changes could we have made to stop this event handler from being called? There is quite a bit of Javascript going on, so this could be the culprit too...
I'm trying to get this accordian to get my data to display with a gridview in it, it renders fine, my datatable is being filled and it seem to bind but then there it no data and it skips my itemdatabound event in my code behind... Nothing loads!

I'm creating a next/previous function for my repeater using pageddatasource. I added the link button control dynamically in my oninit using the following code.
LinkButton lnkNext = new LinkButton();
lnkNext.Text = "Next";
lnkNext.Click += new EventHandler(NextPage);
if (currentPage != objPagedDataSource.PageCount)

So I am incrementing the cookie I am using to track the page number and then rebinding the repeater.
Here is the main issue. The first time I click Next, it works, it goes to Page 2 without any problems. When on Page 2, I click Next, it goes back to Page 1. Seems like the Next event is not wiring up properly.
I have a simple search user control that consists of a textbox. The textbox's onchanged event appends the entered text to another page address and response.redirects to that page. The target page reads the query parameter and displays the results. Works great the first time a search term is entered. The problem comes if I immediately enter another search term, instead of refreshing the search results page with the new query parameter, it jumps back to my default.aspx page. I'm not sure where its getting that as an address to redirect to, the only control with default.aspx as a target is a imagebutton on my master page. I've tried turing off the autopostback on the textbox but it didn't help the problem.
Here's the search user control

I have a CreateUserWizard control, for which I customized the first step.
All I did was add 3 DropdownLists to represent Date of Birth fields. So I have Month, Day, and Year dropdowns.
I have ViewState disabled at application level (disabled it in web.config).
I enabled viewstate on Month, enabled AutoPostback = true, and have a method for the event OnSelectedIndexChanged.
Depending on the Month, the values in Day can range from 28-31.
Now when I fill out the form and hit Create User, the Month_OnSelectedIndexChanged event gets fired first for some reason. I found this out by debugging. Because of this, it does not save the Day the user has picked.
I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:
[Code]....
Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.
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);
