CommandArgument returns empty string.

[Renilkumar]

I have a datagrid using link button. I am setting the CommandArgument value as ..

<asp:linkbutton runat="server" 
        EnableViewState=True 
        CommandArgument='<%# DataBinder.Eval(Container.DataItem, "EmpId")%>'
....>

In the .aspx.vb file I am referring this value as..

Private Sub results_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles results.ItemCommand
   If e.CommandName = "Delete" Then
      Dim sEmpId As String = e.CommandArgument
 

The sEmpId is returning empty.
But If I hard code the value of CommandArgument as..

<asp:linkbutton runat="server" 
        EnableViewState=True 
        CommandArgument='190765
'....>

Its giving the correct value.. any idea why its not returning the value ?

Renil.

Hi,

Probably ,EmpId may be containing Null for that row.You can Debug by assigning some other column.

No its not NULL.

I had this problem too, and I solved it by disabling ViewState on the LinkButton.
