[Loki]

Hi Telerik team,

i strucked in getting result in rad grid footer. bcoz itemdatabound firing twice in vb.net, result is getting doubled.

 

Dim total As Integer
    Protected Sub grdAddList_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles grdAddList.ItemDataBound
        Try

            If TypeOf e.Item Is GridDataItem Then
                Dim dataItem As GridDataItem = CType(e.Item, GridDataItem)
                Dim fieldValue As Integer = Integer.Parse(dataItem("Amount").Text)
                total = (total + fieldValue)
            End If

            If TypeOf e.Item Is GridFooterItem Then
                Dim footerItem As GridFooterItem = CType(e.Item, GridFooterItem)
                footerItem("Amount").Text = "Total: " + total.ToString()
            End If
          

        Catch ex As Exception
            Dim strExpMsg As String
            strExpMsg = className & "." & MethodBase.GetCurrentMethod().Name & "()" & "->" & ex.Message.ToString()
            ExceptionHandler(strExpMsg, ex, Me.strUserName)
        End Try
    End Sub

 

Thanks,

Hello Lokesh,

I have replied to your query in the other thread you have submitted and suggest we continue the conversation there. Please check out the following link:

With that said, for calculating totals and displaying the result in the grid footer you should use the approach described in the following thread:
