Hi, i read the documentation for "custom-sorting" and "Setting Sorting Programmatically" but that´s not my case.
i need a possibility to add a custom-sorting only for one column and sort with the data of a hidden column.
What´s the right way to do that?
Best regards
Martin

Hello, Martin,
In the CustomSorting event the Handled argument of the GridViewCustomSortingEventArgs allows you to control whether the default sorting logic will control the sort order of the rows (by setting the Handled argument to false) or your custom logic will be applied (by setting the Handled argument to true) via setting the SortResult.
The following code snippet demonstrates a sample approach how to apply custom sorting only for the ProductID column and leaжe the basic sorting for the rest of the columns:
Please refer to the following help article which demonstrates how to use the custom filtering logic: https://docs.telerik.com/devtools/winforms/controls/gridview/sorting/custom-sorting
I hope this information helps. If you need any further assistance please don't hesitate to contact me.

this.radGridView1.CustomSorting += radGridView1_CustomSorting;
}
private void radGridView1_CustomSorting(object sender, GridViewCustomSortingEventArgs e)
{
if (this.radGridView1.SortDescriptors.Contains("ProductID"))
{
//use custom sorting logic
e.Handled = true;
e.SortResult = e.Row1.Cells["ProductID"].Value.ToString().CompareTo(e.Row2.Cells["ProductID"].Value.ToString());
}
else
{
//leave the basic sorting logic
e.Handled = false;
}
