Web Forms :: Link Button On User Control Not Firing?
Feb 5, 2010
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!

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 have a user control, which is added to another user control. The nested user control is built up of a GridView, an image button and a link button. The nested user control is added to the outer control as a collection object based upon the results bound to the GridView.
The problem that I have is that my link button doesn't work. I click on it and the event doesn't fire. Even adding a break point was not reached. As the nested user control is added a number of times, I have set image button to have unique ids and also the link button. Whilst image button works correctly with its JavaScript. The link button needs to fire an event in the code behind, but despite all my efforts, I can't make it work. I am adding the link button to the control dynamically. Below is the relevant code that I am using:

Here is my requirement -
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.

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 have a link button thats text value is populated from a dataset value retrieved from a database. When the user clicks on this link button I want to somehow capture the text value. The trick is the linkbutton is within a usercontrol, and I want to do the processing from the user controls parent. I am able to get the ID of the clicked linkbutton with the use of Request.Form["__EVENTTARGET"];, however i need the text value, in this case its a job number.
I may be able to do this via javascript with the OnClientClick;
OnClientClick='<%# DataBinder.Eval(Container.DataItem,"JobNo","test({0})")%>'
When I do this I get a javascript error saying "M10725"(which is my job number being clicked) is ndefined. I dont know what this means. Do I somehow have to give the linkbutton being click a value?

I have a datalist inside of an updatePanel. Within the datalist, for each item I have a linkbutton that when clicked I would like to fire the OnDeleteCommand of the datalist so that I can delete the record.
Problem is that I can never get the event to fire, it simply does a postback and then does not fire the event specified inthe "OnDeleteCommand" argument of the datalist control.
I've read many postings with similar entries, but nothing has worked.

There are two user controls, which are built dynamically.
In the first control, I am adding a link button, and trying to attach a click event on the same. But the event is not fired.
Actually the main goal is, when the link is clicked, based on which one is clicked, I need to show second control (the values on the new controls are based on the first controls link button that is clicked).
If I use javascript, I will need to use ActiveX or is there any other way to instantiate the second control using javascript

When user logs in this text has to be changed from code but due to caching on the page none of them is changed.label I can replace with substitution control. Is there any way out to change linkbutton text now.

I need to change a standard HTML Input button to a Link button but am running into problems because the existing
code calls a javascript function. The function basically does the same as the browser back button. When I add the code and
set the property runat="server" I get a "CS1026: ) expected".
Quite new to ASP,net (VS2010) so could be going about this the wrong way.

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 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

Here's the code behind

I have a web app connected to a database. I have a ajax tab control on the page with a textbox and a button in a panel that will update the database with whatever the user types in the textbox. But I cant seem to get the behind code to work, I assume the button is not firing.
HTML Code:
<asp:ScriptManager ID="ScriptManager2" runat="server"></asp:ScriptManager>
<ajaxToolkit:TabContainer ID="TabContainer2" runat="server">
<ajaxToolkit:TabPanel>
<asp:TextBox ID="name" runat="server"></asp:TextBox>
<asp:Button ID="updater" runat="server" Text="Button" />

I have Web page that uses LinkButton control inside Template Fields of Gridview.I am trying to work on LinkButton Click event and trying to preserve the Value of LinkButton that user click, and based on that value, i want to refresh tha page data.
I used CommandName and CommandArgument property of Linkbutton, but i can use that property only in GridView_RowCommand method by checking e.CommandName expression. But the problem with that Gridview_RowCommand event fire after all other page_load activity. So the value never used in the page_load event to refresh the data in all other control.I also tried to use OnClick Method, Session variable and Hidden variable. but when i run Response.Redirect method from Gridview_RowCommand, it clear all the Session and Hidden variable values. also tried (Response.Redirect(,false)) method but never got success.
