GridButtonColumn Delete button

[Bob]

Hi all,

I have radGrid and I added a Delete button.  When clicked, I want to fetch the DataKeyNames value and then delete the corresponding row in my sql table.  I already have the radgrid set-up and I also have a method to delete the row.  What I cannot figure out is how to get the value of the selected DataKeyNames.  I am trying this but it's not working:

Dim

iPolicyId As Integer = Convert.ToInt32((e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("PolicyId")))

Any ideas on how I can get this value?

Thanks,
Bob

Bob,

My Delete operation works as follows. May be you could try the same.

    protected void ActivityGrid_DeleteCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
    {
        GridEditableItem eitem = e.Item as GridEditableItem;
        Hashtable newValues = new Hashtable();
        eitem.OwnerTableView.ExtractValuesFromItem(newValues, eitem);      
        int id = Convert.ToInt32(newValues["ActivityID"]);

Piyush,

I converted your code to vb.net as follows:

Dim

eitem As GridEditableItem = TryCast(e.Item, GridEditableItem)

Dim newValues As New Hashtable()

eitem.OwnerTableView.ExtractValuesFromItem(newValues, eitem)

Dim id As Integer = Convert.ToInt32(newValues("PolicyId"))

But id = 0 when I run this.  What am I doing wrong?

Thanks,
Bob

Hello Bob,

Did you add DataKeyNames="PolicyId"  in the markup for the corresponding GridTableView? In code-behind it would look like this: RadGrid1.MasterTableView.DataKeyNames = new String() {"PolicyId"}

Sorry guys, this was working all along.  I found out my client has a row with PolicyID = 0 in their database.  It just happened this was the row I was testing with.  I kept seeing the value = 0 and it threw me off.  So thanks for everyone's help.
