GridView not refreshing in UpdatePanel after selecting LinkButton

Posted By:      Posted Date: October 11, 2010    Points: 0   Category :ASP.Net

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"

Dynamically creating Gridview Template - Linkbutton Click not working



I have written some code to dynamically generate template columns for gridview which works well. However, each cell in the gridview has to be a linkbutton, which when clicked does a db update and redirects to a specific url with some parameters in it.

I have attached a click event handler to the linkbutton in the InstantiateIn method but the event does not seem to fire.

Could someone please help? the code is below -

AutoPostback in Repeater in UpdatePanel is refreshing the page

Here's quite a weird problem:I've got a TextBox with AutoPostBack="true" and OnTextChanged property set.The textbox is located inside a Repeater, which in turn is located inside an UpdatePanel.Problem is - whenever the TextBox postsback, the whole page gets reloaded, instead of the UpdatePanel only.Here's how the thing looks:<asp:UpdatePanel runat="server"> <ContentTemplate> <asp:Repeater ID="itemsRepeater" runat="server"> <HeaderTemplate> <ul class="lstProducts"> </HeaderTemplate> <ItemTemplate> <li> <asp:TextBox AutoPostBack="true" OnTextChanged="whatever_Click" runat="server" /> </li> </ItemTemplate> <FooterTemplate> </ul> </FooterTemplate> </asp:Repeater> </div> </ContentTemplate> </asp:UpdatePanel> Interesting thing is, if I take the TextBox out of the repeater, it refreshes only the UpdatePanel.So is if I put a Button inside the repeater - only the UpdatePanel gets refreshed.But whenver I place an AutoPostBack-ing control inside the Repeater, the whole page gets refreshed.Any help would be welcomed,Thanks<asp:UpdatePanel runat="server">             &

Refreshing datalist in updatepanel


I have a datalist. When a user clicks a button in the datalist I change some properties and then want to refresh the datalist. However, the code below doesnt seem to refresh the datalist. Once I reload the entire page (which I dont want) the changes are visible in the datalist.
I also tried setting the updatemode of the updatepanel to "Conditional" and update manually in the dlPhotos_ItemCommand, but that doesnt work either.

In bold I've marked where I want to refresh the datalist

UpdatePanel, GridView and Timer controls used together - OnTick() and DataBind



I am currently working on a page that contains a GridView control which is bound to an ObjectDataSource control.  The ObjectDataSource invokes a method on a DAO layer class that returns a DataTable and all is working just fine.  Paging and Sorting are enabled and work ok as well.  I have "wrapped" the GridView control inside an <UpdatePanel><ContentTemplate> construct and now the Paging and Sorting occur w/o the Page reload as expected - still no problem. 

However, now I want to have the GridView simply refresh itself every 5 to 10 seconds so I placed a Timer control w/ an interval of 5000 milliseconds INSIDE the UpdatePanel.  I am sure there is more that must be wired and have had trouble finding a good article where the UpdatePanel, TimerControl, and GridView control are used together.  Examples that I have seen use Label controls and implement the OnTick event but it is not clear yet to me how to use this w/ a databound control like a GridView.  Can anyone suggest a link or 2 showing an example of this scenario. 

NOTE:  I am not currently programmatically "binding" the GridView control.  The GridView control and ObjectDataSource control are simply bound by setting the DataSourceID property of the GridView to the ID of the ObjectDataSource - they are bou

Edit LinkButton in GridView


Dear All,

I have a problem and not getting why is it so. I have a grid view and it contains some 10,000 rows without any pagination. For each Row I have a Edit LinkButton n the TemplateField. On the click of this edit LB the control should go to some Edit Page. The problem here is that after clicking on the LB the page is taking lots of time. On the other hand if I am doing pagination in the GridView and assgning page size = 10 then it is loading very fast. Can anyone please tell me what is the reason. I cant have the pagination for this gridView




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 = @"

Selecting radio buttons in a gridview with dataset from Linq Query


Hi Everyone!

I've got a gridview that will allow clients to edit options they've already entered on another page.  The gridview has three radio buttons in it each with a value of 1,2,3.  The option value in the dataset is 1,2 or 3 respectively.  I would like to have the radiobutton with the corresponding value selected in the gridview so they can see what they previously chose and will then be able to edit, if they wish.

How do I do this? 

Here's my code so far:

Dim clientOption = (From c In dc.ClientOptions _
                                 Where c.clientID = userClientID _
                                 Select New With {c.clientOptionID, _
                                                  c.optionWording, _

            'Now Populate Gridview 1 with set options
            If clientOption Is Nothing Then
                Label1.Text = "There are currently no set options to edit."

                GridView1.DataSource = clientOption
                Label1.Text = "Edit set options."
            End If

            <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="F
