Error occured when column header click

[User (Old forums)]

Hi

 

I have used following code sample to bind the data able to
the grid.

GridControl1.BeginInit()

GridControl1.DataSource =
ds.Tables(0).DefaultView

GridControl1.ValueMember = “OrganizationID”

Dim cell As Xceed.Grid.DataCell

 For Each cell In
GridControl1.DataRowTemplate.Cells

      AddHandler
cell.DoubleClick, AddressOf Me.cell_DoubleClick

      AddHandler
cell.MouseDown, AddressOf Me.cell_MouseDown

      AddHandler
cell.KeyDown, AddressOf Me.cell_KeyDown

      AddHandler
cell.Click, AddressOf Me.SelectedValueCahnge

  Next cell

  For Each col As
Xceed.Grid.Column In GridControl1.Columns

      AddHandler
col.WidthChanged, AddressOf Me.cell_WidthChange

  Next col

AddHandler
GridControl1.Resize, AddressOf Me.grid_Resize

AddHandler
GridControl1.DataRowTemplate.Cells(“CountryID”).ValueChanged,
AddressOf Me.FormatCountryColumn

AddHandler GridControl1.DataRowTemplate.Cells(“VisitCountryID”).ValueChanged,
AddressOf Me.FormatCountryColumn

 

GridControl1.EndInit()

 

FormatCountryColumn is used to replace the
country ID using the Country name.

Private Sub FormatCountryColumn(ByVal
sender As Object,
ByVal e As
System.EventArgs)

    If TypeOf (sender) Is
Xceed.Grid.DataCell Then

       Dim cell
As Xceed.Grid.DataCell = CType(sender, Xceed.Grid.DataCell)

       If Not cell.Value Is
DBNull.Value AndAlso Not
cell.Value = “” Then

         cell.Value =
m_oCountry.GetCountryName(Convert.ToString(cell.Value))

       End If

    End If

End Sub

 

In the first time grid load code is
successfully run.

But when I click the “Country”
column header it raise the following error.

When I disable the column header
sorting facility using ,

.Columns(“CountryID”).CanBeSorted
= False then error is not raised.

But column header sorting is a
requirement.

Can you please help to resolve this?

 

Here is the error details

Also I have notice that when I
change the country ID to Country name “FormatCountryColumn”
function is executed again. ( I think event is fired again).
