gridView RowEditing

[davebat]

I have the follwoing function which loops through 3 datagrids on my page and should disable all other edit buttons when one edit button is clicked.

Protected Sub DisableEdit()
        Dim c As Control
        Dim content As ContentPlaceHolder
        content = Page.Master.FindControl("contentplaceholder1")
 
        Dim grid As GridView
        Dim frow As GridViewRow
 
        For Each c In content.Controls
            If c.GetType() Is GetType(GridView) Then
                grid = CType(c, GridView)
                For Each frow In grid.Rows
                    If (frow.RowType = DataControlRowType.DataRow) Then
                        If Not frow.RowState = DataControlRowState.Edit Then
                            Dim btnEdit As LinkButton = frow.Cells(8).Controls(0)
                            btnEdit.Enabled = False
                        End If
                    End If
                Next
            End If
        Next
 
    End Sub

I call this on the RowEditing of each gridview, unfortunately RowEditing Occurs when a row's Edit button is clicked, but before the GridView control enters edit mode. Which means it turns them all to false but re-binds the gridview that called the fucntion, which in turn renders all fo the controls visible.

Does anyone know of a workaround for this, or the correct event to use that will fire after the control enters edit mode
