Excel Export (Unbound Fields)


I have a Grid Grouping Control that has both bound, and unbound columns.  I am setting the values of the unbound columns in the RowDataBound event, and all is well.  Now I have a need to export the entire grid to Excel.  I am using the following code:

Dim excel As New GridExcelExport(Me.GridGroupingControl1, "C:\ReworkCost.xls", ConverterOptionsExt.Visible)
excel.ExportNestedTable = True

I have also tried "ConverterOptionsExt.All".  The problem is that the unbound cells are empty in the Excel Export.  I found a previous post on this subject at http://www.syncfusion.com/support/forums/grid-aspnet/102027 where Syncfusion stated "We can only export the bound columns to the excel/word".  I am hoping that this is incorrect, or has changed since 2011.  What is the point of an export function, if it doesn't work 100%?

I need to export a grid to Excel with all of the data intact (both bound and unbound fields).

Hi Dale,


Thanks for using Syncfusion products.


We suggest you to inherit the GridExcelExport class and override the CopyStyles method to achieve your requirement. Please refer to the code snippet below.


  Public Class mycustomExport

        Inherits GridExcelExport

        Public Sub New(ByVal ggc As GridGroupingControlByVal fileName As String)


            MyBase.New(ggc, fileName)

        End Sub



        Protected Overrides Sub CopyStyles(ByVal style As GridTableCellStyleInfoByVal rowIdx As IntegerByVal colIdx As Integer)


            Dim range As IRange = Me.Sheet(rowIdx, colIdx)


            If style.TableCellIdentity.DisplayElement.Kind = DisplayElementKind.Record AndAlso style.TableCellIdentity.Column.HeaderText = "TestCurrency" Then

                Dim nTest As Double = 0.0

                nTest = rowIdx + 1

                Dim nPi As Double = nTest * Math.PI


                range.Text = String.Format("{0:C}", nPi)

            End If



        End Sub

    End Class
