SelectedItems is zero

[Thanh Dang]

Hello

I'm getting value of a cell in selected row in RadGrid. I have enable Client-Side Row Selection and PostBackOnRowClick.

<telerik:RadGrid ID="RgdOffer" runat="server" CellSpacing="0"
     EnableEmbeddedSkins="False" GridLines="None"
      onitemcommand="RgdOffer_ItemCommand" onitemdatabound="RgdOffer_ItemDataBound"
        Skin="GPF" CssClass="shadow">
   <ClientSettings EnableRowHoverStyle="True" AllowColumnsReorder="True"
        EnablePostBackOnRowClick="True" ReorderColumnsOnClient="True">
       <Selecting AllowRowSelect="True" EnableDragToSelectRows="False" />
   </ClientSettings>

And from code-behind, I get the value of the cell with this code snippet in ItemCommand event:

if (e.CommandName == "RowClick" && e.Item is GridDataItem)
            {
                // String to store OfferNo
                string strOfferNo = null;

                // Get OfferNo of selected Offer
                foreach (GridDataItem item in RgdOffer.SelectedItems)
                {
                    strOfferNo = item["OfferNo"].Text;
                }

And it did work. 

But when I put my grid in to a RadDock, then SelectedItems always return 0.

I don't know why?

Can you help me explain this problem?

Thank you.

Hello Thanh,

Try the following code snippet to get the SelectedItems.
C#:

protected void RadGrid1_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
 if (e.CommandName == "RowClick" && e.Item is GridDataItem)
   {
       foreach (GridDataItem item in RgdOffer.MasterTableView.Items)
       {
        string strOfferNo = item["OfferNo"].Text;
       }
   }
}

Thanks,
Shinu.

Thanks for your reply Shinu

But your code snippet seems to miss something... I don't see Selected elsewhere. 
This code snippet just iterate through all items in the grid. But what I need is the value at selected row only.
I have tried putting if (item.Selected)but still no luck.
Would you look at this once again.

Thanks

Thank you for contacting us.

For more information on looping and extracting selected row keys you can get a look at the following article:

Hello Genti

The problem here is that RadGrid1.SelectedItems always return 0 item.
I'm wondering if RadDock or RadAjaxPanel may cause some effect to RadGrid, as I put the grid under a AjaxPanel and a Dock.
