I have written below code

Try
            DG.TableStyles.Clear()
            DG.Refresh()
            sp_cnt = 0


            DG.TableStyles.Clear()
            tablestyle.MappingName = mdetabname
            tablestyle.HeaderBackColor = System.Drawing.Color.Pink
            'tablestyle.MappingName.Remove(0, Len(mdetabname))
            

            Do
                If sacarray(sp_cnt) <> "" Then
                    Dim tablestyle2 As New DataGridTextBoxColumn
                    ' MsgBox(TableStyle1(0).ToString())
                    tablestyle2.MappingName = sacarray(sp_cnt)
                    tablestyle2.Width = 100
                    tablestyle2.HeaderText = MappArray(sp_cnt)
                    MsgBox(sacarray(sp_cnt) & " " & MappArray(sp_cnt))

                    tablestyle.GridColumnStyles.Add(tablestyle2)
                    tablestyle2.Dispose()
                    sp_cnt = sp_cnt + 1

                Else
                    Exit Do
                End If
            Loop


            DG.TableStyles.Add(tablestyle)
            DG.Refresh()

sacarray() - I have taken different fields using string operation from 12 different select statements statement and stored it in "sacarray".
for

MappArray() - I m taking values from database and storing it in this array.

there are 50 different rows fro mapping array
these 50 rows are divided into 12 tables.

and mapping these two array in above code


At first it runs fine.
but when i try to apply different combination i m getting following error:

"Error: Datagrid columnstyle collection already contains a columnstyle
with the same mapping "
parameter name: column

please clarify how i can remove a columnstyle from a datagrid before applying new one.

I believe that you can use GridColumnStyle s.clear() to clear all column styles or GridColumnStyle s.remove(tables tyle2) just to remove that one.

Thank You very much

I stored that datagridcolumns tyle to an array before adding.
and using that array i removed datagridcolumns tyle one bye one before adding new tablestyle.

I had worked on that code for 3 days so thanx once again.....
