[Solved] AlternateRowBackground starting on first row

[Jarred Froman]

We are able to get the alternating row colors to work by setting AlternationCount = 2, however, we would like the alternate background/style to start on the first row.  Is there an easy way of accomplishing this?

Thanks,

Hello Jarred Froman,

 

You may track the row index and set the background of a row based on your custom logic.
For example you may subscribe to the RadGridView's RowLoaded event and based on the row index you may paint its background, as shown below:

private void radGridView1_RowLoaded(object sender, Telerik.Windows.Controls.GridView.RowLoadedEventArgs e)
      {
          if (e.Row is GridViewHeaderRow || e.Row is GridViewNewRow || e.Row is GridViewFooterRow)
              return;

          var row = e.Row as GridViewRow;
          int index = this.radGridView1.Items.IndexOf(row.Item as Item);
          if (index % 2 == 0)
          {
              row.Background = new SolidColorBrush(Colors.Red);
          }
          else
          {
              row.Background = new SolidColorBrush(Colors.White);
          }
      }

Furthermore you may also achieve the desired result using StyleSelectors. 

All the best,
