  Hello,

  I’m using an old componentone C1Datagrid for WPF Version 3.0.20093.100. During runtime the quantity of the displayed columns are dynamically. So I’m using a variable and if its true, I want to change the backgroundcolor of the specific column.

  Its not working but the Codesnippet should explain, what i want to do:

  …
  
  For Each column In DG_Maschinenplanung.ActualColumns

                      Select Case CInt(txt_AnzahlWochen.Text)
  
                          Case 1
  
                              If column.Caption.Contains(CStr(int_WeekOfYear)) Then
  
                                  column.SetValue(BackgroundProperty, New SolidColorBrush(Colors.Blue))
  
                              End If   ...........................
  

  Could you pleas help me to make this function working?

  Thanks in advance and best regards
  
  Christoph

  Hi,

  You are using a very old version. This is out of support. We suggest you to update to the latest 4.6.2 version.

  However, to achieve your requirement with C1DataGrid Version 3.0.20093.100. You can create your custom **ItemCellContentPresenter **and can ApplyTemplate as:(see code snippet)

     public class CustomeItemCellContentPresenter : ItemCellContentPresenter
      {
          public override void OnApplyTemplate()
          {
              base.OnApplyTemplate();
              if (this.Cell.Column.Caption == "Name")
              {
                  (this.Parent as Border).Background = Brushes.Red;
              }
          }
      }

  Please refer the attached sample for the same : DataGridDemo.zip

  Best Regards,
  
  Nitin
