Linkbutton not fire inside the Updatepanel

Posted By:      Posted Date: September 16, 2010    Points: 0   Category :ASP.Net
I have a page with two ajax toolkit popupcontrol extenders, both have a Linkbutton inside the popup window, which is inside a panel and updatepanel. The difference is the second one (Linkbutton2) is inside a Gridview, which is also inside a Updatepanel. The first one works fine, but the second one does not fire when click on it. Please help. The code is as follows: <asp:LinkButton ID="lbnAdd" runat="server" onclick="lbnAdd_Click1">Add New... </asp:LinkButton> <cc1:PopupControlExtender ID="lbnAdd_PopupControlExtender" runat="server" DynamicServicePath="" Enabled="True" ExtenderControlID="" TargetControlID="lbnAdd" PopupControlID="pnlTemplate"> </cc1:PopupControlExtender> <asp:Panel ID="pnlTemplate" runat="server" style="display:none" CssClass="popup_template" Width="499px">asp:UpdatePanel ID="UpdatePanel2" runat="server">  <Triggers>  <asp:PostBackTrigger ControlID = "LinkButton1" />  </Triggers>   <ContentTemplate>table style="width:500px; height: 182px; border-collapse: collapse;">  <tr> <td class="style28">  </td>   <td class="style9">

LinkButton inside UpdatePanel not executing onClick javascript



So, I have a MasterPage, in which I have an ImageButton and an UpdatePanel. Inside the UpdatePanel I have a LinkButton.

<asp:ImageButton ID="imgPdf" runat="server" ImageUrl="~/Images/pdf.png" OnClick="LnkRelease1_Click" ToolTip="Document1.pdf" Width="31px" />

<asp:UpdatePanel ID="UpdatePanel9" runat="server">                                                                                    

<asp:LinkButton ID="LnkRelease1" runat="server" OnClick="LnkRelease1_Click" ToolTip="Document1.pdf" Font-Underline="false">View Pdf</asp:LinkButton>



As you can see, both components are asociated to the same OnClick event, which should open said PDF document in a new window
using javascript (Code Behind of the MasterPage):

protected void LnkRelease1_Click(object sender, EventArgs e)
     try {   if ((((System.Web.UI.WebControls.WebControl)(sender))).ToolTip != "") { string script = @"

UpdatePanel inside a WebPart

I am having problems trying to use an UpdatePanel inside a webpart, the async postback is happening (checked using fiddler and debugging the project to see the events firing), but the contents of the UpdatePanel on the page is not being updated, at the moment all I have in the UpdatePanel is<%=Date.Now.ToString%>To debug it to see if its working, but its not changing, ive tried turning off EnablePartialRendering on the ScriptManager to ensure it works when a normal postback happens and its fine.Any ideas why is not working? Thanks for any help

ReportViewer inside UpdatePanel not working


Has anyone been able to get the ReportViewer to work correctly inside an UpdatePanel?

For me the report renders fine on the initial whole-page refresh, but when I click the next page button the next page renders but doesn't allow me to navigate through the pages anymore. The toolbar says "(blank) of 0" pages and the arrow toolbar buttons for navigating between pages are all disabled.

cannot bind dropdownlist inside from button click inside updatepanel



I have a gridview inside UpdatePanel. 

Inside gridview there is a dropdownlist and a button on each row. On button click I am opening a panel through Modal popup extneder.

Inside that pop up there is again a dropdownlist. I am adding an item into this dropdownlist based on the selection from the dropdown inside gridview. 

like  ddl.items.insert(0,'xyz');

But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.

Please let me know how to fix this. I tried UpdateMode conditional and always but didn't worked. If I am not clear let me know.

Updating an ASP.NET CheckBoxList inside an UpdatePanel from a Javascript function



I have a asp.net listbox server control that is connected to a jquery plugin that can handle a client side click event for each of the checkboxes it renders.

Whenever I click on a checkbox the click event gets triggered and I make a call to

__doPostBack("UpdatePanel1"""); so that i can update the updatepanel and rebind the checkboxlist inside it.

is it possible to do the rebind first, and then update the updatepanel? how do i do that? because now, the rebind happens on the second time i click on the checkbox.

Problem with Editing image inside DetailsView inside UpdatePanel



I have a problem and I really hope you'll be able to help me.

I'm trying to add and edit an image which is located in a detailsview which is inside an UpdatePanel. After I read relevant topics in the forum I installed the Ajax Control Toolkit. Below is my source code. When I used it only for insert new image it worked great. The problem caused when I tried to implement it on the Edit mode, i.e. when I tried to edit the image and upload a different image.  Unfortunately it didn't work as I hoped. Nothing happend and the image hasn't been changed. I also tried to change the IDs (AsyncFileUpload ID) to be the same in both places but it didn't work either.

The source code:

<asp:DetailsView ID="dvMovie" runat="server" Height="50px" Width="695px"
                    AutoGenerateRows="False" DataSourceID="sdsMovieById"      
                     BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px"

ASP Image inside UpdatePanel changing ImageUrl



I have a WebForm which has an update panel. Inside the panel I have an ASP Image. I have also, 2 ImageButtons which act as the triggers for the UpdatePanel.

<asp:UpdatePanel ID="updImage" runat="server">
          <asp:AsyncPostBackTrigger ControlID="btnBackward" EventName="Click" />
          <asp:AsyncPostBackTrigger ControlID="btnForward" EventName="Click" />
          <asp:Image ID="Image1" runat="server" Width="75px" Height="75px" BorderStyle="Solid" BorderWidth="5px" BorderColor="White" />

In my WebForm, I also have an ASP Image component outside the Update panel.

The ImageUrl of those ASP Image components are loaded from a folder that is outside the WebSite root folder, using the code found in this link:


GridView not refreshing in UpdatePanel after selecting LinkButton


I need help with a GridView that appears in an AJAX UpdatePanel. This GridView contains a TemplateField with a LinkButton that displays a text value.  When the link button is clicked, the code behind needs to capture the text value of the button, and then refresh the GridView with an asynchronous postback within the UpdatePanel and display the updated output.

The post-back event is occurring, and I'm able to capture the event in Visual Studio 2010 debugger.  But, the screen contents do not change after this event occurs.  No exception gets thrown, at least from what I can see in debugger.

Portions of the sanitized code appear below.  The GridView actually appears on a page that contains 2 dropdown lists and 2 other GridViews.  There is just one UpdatePanel on this page.

<asp:UpdatePanel runat="server" ID="upMain" ChildrenAsTriggers="false" UpdateMode="Conditional">
        <asp:AsyncPostBackTrigger ControlID="grdProcesses" EventName="RowCommand" />

		<asp:GridView runat="server" ID="grdProcesses" AutoGenerateColumns="false"
		    BorderColor="#7f9db9" BorderStyle="Solid" CssClass="tblBase"
