ASP.NET 2.0 equivalent for e.Item.ItemIndex ?

Hello,

I'm raising an event in a datagrid when clicking on a deletecommand button.
I want to get the selected value of the datagrid.

In ASP.NET 1.1 I did this whit e.Item.ItemIndex
In ASP.NET 2.0 I can't use this anymore because EventArgs e has only the
properties/methods tostring, Equals, getHashcode and getType.

Does somebody know a solution for this ?

thx,

Use the ItemCommand event:

It should work just the way you're familiar with because
DataGridCommandEventArgs still has the Item property.

Protected Sub dataGrid1_DeleteCommand(ByVal source As Object, ByVal e
As DataGridCommandEventArgs) Handles dataGrid1.DeleteCommand

lbl.Text = "Deleting row number " & e.Item.ItemIndex
myDataView.Delete(e.Item.ItemIndex)
dataGrid1.DataBind

End Sub

Hi, this works but e.Item.ItemIndex returns the number of the row in the
datagrid, but not the datakeyfield.
How can i see this ?

thx

Are you asking how to get the primary key value for the row in
question? If you are then use the DataKeys collection property of your
DataGrid.

'Within the DeleteCommand (or ItemCommand event handler and filtering
for the delete command)
datagrid1.DataKeys(e.Item.ItemIndex)
