Hi,
I am generating the RadGrid (ASPNET AJAX Q1 2008) dynamically (Creating entire grid programmatically). Since the grid has child controls (as part of GridTemplateColumn & PagerTemplate) I had set EnableViewState = False for Grid as well as page (according to this article: http://www.telerik.com/help/aspnet-ajax/grdprogrammaticcreation.html). But the problem is I have “ImageButton” inside GridTemplateColumn. It has CommandName property set. When I click on the ImageButton, it does not trigger “ItemCommand” event handler. But the LinkButton works perfect. So, in order to make sure I am doing right; I had created a sample project which does the similar functionality. Here is the code:
<%@ Page Language="C#" AutoEventWireup="True" EnableEventValidation="false" CodeBehind="RadGridTest.aspx.cs" Inherits="Adc.Web.AdBid.Views.CampaignView.RadGridTest" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"/>
<telerik:RadGrid ID="rad" runat="server" runat="server" EnableViewState="False" OnNeedDataSource="RadGrid_NeedDataSource"
OnItemCommand="RadGrid_ItemCommand" OnItemDataBound="RadGrid_ItemDataBound" AllowPaging="true" AutoGenerateColumns="false"
HeaderStyle-Wrap="true" PagerStyle-AlwaysVisible="true">
<MasterTableView PagerStyle-AlwaysVisible="true" EditMode="InPlace" TableLayout="Auto" ShowFooter="True" >
<Columns>
<telerik:GridTemplateColumn UniqueName="CampaignName" DataField="CampaignName" HeaderText="Campaign Name">
<ItemTemplate>
<asp:LinkButton ID="testCampaignBtn" runat="server" CommandName="Campaign" Text='<%# DataBinder.Eval(Container.DataItem,"CampaignName") %>'></asp:LinkButton>
<asp:ImageButton ID="testCBtn" runat="server" CommandName="EditCampaign" ImageUrl="~/Images/edit_icon.gif" EnableViewState="true" />
</ItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridBoundColumn UniqueName="Status" DataField="Status" HeaderText="Status"></telerik:GridBoundColumn>
<telerik:GridTemplateColumn UniqueName="EditCampaignImage">
<ItemTemplate>
<asp:ImageButton ID="testImageBtn" runat="server" CommandName="EditCampaign" ImageUrl="~/Images/edit_icon.gif" EnableViewState="true" />
</ItemTemplate>
</telerik:GridTemplateColumn>
</Columns>
<RowIndicatorColumn Visible="False">
<HeaderStyle Width="20px" />
</RowIndicatorColumn>
<ExpandCollapseColumn Visible="False" Resizable="False">
<HeaderStyle Width="20px" />
</ExpandCollapseColumn>
<EditFormSettings>
<PopUpSettings ScrollBars="None" />
</EditFormSettings>
</MasterTableView>
</telerik:RadGrid>
</form>
</body>

param[3] = Adc.Data.AdBid.CampaignStatus.All;
CampaignPresenter p = new CampaignPresenter();
CampaignDataMiner miner = new CampaignDataMiner();
ISelfServiceViewData data = miner.GetData(param);
CampaignCollection cc = ((Adc.Data.AdBid.Campaign)data).CampaignSummaryCollection; ;
rad.DataSource = cc;
rad.VirtualItemCount = miner.GetVirtualItemCount(param);
}
}
}
}
Note that it’s a sample project for your reference. In actual project I am generating the grid programatically. Please provide the solution to this at the earliest. Some one can please help me with a better solution.

I tried this on my end and it is working well with EnableViewState set to true but i get an error when it is set to false. Try to achieve the same with EnableViewState set to true. I am not sure whether there exists any alternative to achieve this with EnableViewState set to false.
Here is the code I tried.
ASPX:
| <telerik:GridTemplateColumn UniqueName="TempCol1" DataField="ProductName" SortExpression="ProductName" HeaderText="TempCol1" > |
| <ItemTemplate> |
| <asp:ImageButton ID="ImageButton1" runat="server" CommandName="ImageCheck"/> |
| </ItemTemplate> |
| </telerik:GridTemplateColumn> |
CS:
| protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e) |
| { |
| if (e.CommandName == "ImageCheck") |
| { |
| } |
| } |
Thanks
Shinu.
