Question

I have a GridView with Cell 0 containing the ID that I need to pass to a Public Sub.

I cannot figure out how to pick the value from Cell 0 in order to pass it to the Sub. I have tried experimenting (see the Dimmed EventID below) but have failed. Here is my code:

Protected Sub gvAppointmentsCalls_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvAppointmentsCalls.RowCommand

        Dim EventID As String = gvAppointmentsCalls.Rows(e.RowIndex).Cells(0).Text

        If e.CommandName = "gvAdd2Outlook" Then
            Send_iCal_Call(EventID)
        End If
    End Sub

If I type the value directly e.g. Send_iCal_Call(123) then it works perfectly.

Public Sub Send_iCal_Call(ByRef Event_ID As Integer)
' My code in here
End Sub

Answer 1

Use the CommandArgument to pass the ID to the RowCommand-Handler.

For example:

CommandName="gvAdd2Outlook" CommandArgument='<%# Bind("EventID")%>'
