asp.net webcontrols : Urgent (please help): Post-back problem
My problem is very clear but crazy. I have a DataRepeater in my page that I have made the paging mechanisem for it with a user control. This user control contains a Repeater too. Let's call this control Paging Control. The Paging control provide some links for paging. When I click the links, It post-back and fill the main repeater in the page. It looks the paging repeater dosen't postback. When I click on the links that have generated in paging control, page dosen't poskback and the related event handler dose not get executes. so the main repeater remain empty. Because I fill the main repeater again in these links' event handler. I think there is some problems in client-side script that .NET Framework generates. Please help me. It's urgent for me to solve this problem. Thanks in advance

Other then that, post some code.
Thnks a lot for your response Leon
But there is not such property (AutoPostBack) in DataRepeater.. I think It's a problem in generated Javascript. This is another sample for the problem. A usercontrol that contains a Repeater and a linkbutton. The repeater itself contains 2 link button. When click the button, it postback and execute page_load and then it's click event handler. When click the the repeater's linkbutton, it postback and only execute page_load. It can not find and don't execute the repeater's ItemCommand Event handler.

In that case the click event will never fire. Furthermore you should handle the click-event for the button not in a specific event for the buttons itself but in the ItemCommand for the repeater (use a CommandArgument to distinguish the different rows if needed), because; let's say you got two rows, with each two buttons, so a row1.button1, row1.button2, row2.button1, row2.button2 and you click button1 --> which in that case should go to button1_click. From which row was it clicked? Use ItemCommand!
I'm using ItemCommand and CommandArgument ...
When I trace the code execution,I see that when I click the generated LinkButton, It make postback and execute the Page_Load event handler, but dose not find the ItemCommand event Handler. The generated javascript code for the generated LinkButton in the repeater is like this: href="javascript:{if (typeof(Page_ClientValidate) != 'function' || Page_ClientValidate()) __doPostBack('Issues_Pager$Repeater1$_ctl1$LinkButton1','')} " Amir [quoted text, click to view] "Leon Friesema" wrote:
