Hello,


Use the "GetDataKeyValue"  method to get the keyvalue of GridDataItem.

Code:

Label16.Text = GridView1.MasterTableView.Items[0].GetDataKeyValue("ID").ToString();

Have a great day... :)

I know this is an old thread, but I spend a lot of time trying to find an answer. After much trial and tribulation, I found this simple line of code that works:

Protected Sub RadGrid1_SelectedIndexChanged(sender As Object, e As System.EventArgs) Handles RadGrid1.SelectedIndexChanged

        Label1.Text = gvRegion.SelectedValue.ToString

    End Sub

Oops, the line should read:

Label1.text = RadGrid1.SelectedValue.ToString

(Sorry 'bout that, chief)

Hi Sean,

Thank you for sharing this solution!

I would like to note that this approach is suitable for scenarios with single row selection (AllowMultiRowSelection="false") and also when there is only one filed set in the DataKeyNames property of the RadGrid.

In cases with disabled RowSelection, enabled MultiRowSelection or multiple DataKeyNames, using the GetDataKeyValue method is recommended, see Accessing Raw Field Data and Key Values

Kind regards,
Doncho
