Private Sub GridViewregisterMsg_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridViewregisterMsg.RowCommand
        Try
            Dim gvRow As GridViewRow = CType(CType(e.CommandSource, Control).NamingContainer, GridViewRow)
            Dim index As Integer = gvRow.RowIndex
            Dim row As GridViewRow = GridViewregisterMsg.Rows(index)

            Dim regmsgRunno As HiddenField = CType(row.FindControl("regmsgRunno"), HiddenField)
