    I am looking for a way to add a search bar text box in the filter dropdown of a combobox column. For example if I have 1000 different possible values in that combobox column and want to filter to see only 5 of them, I want to be able to search for them by their name, instead of scrolling through 1000 entries with chance to miss one.

    Hi Yordan,

    You can override the DataGridComboBoxColumn's GetFilter method and provide the modified DataGridFilter as follows:

    public class DataGridComboBoxColumnEx : C1.WPF.DataGrid.DataGridComboBoxColumn
    public override IDataGridFilter GetFilter()
    var filter = base.GetFilter();
    (filter as DataGridFilter).InnerControl = new DataGridMultiValueFilterEx()
    ItemsSource = ItemsSource
    return filter;

    Please refer to the attached sample for full implementation. (see DataGridFilterSearch.zip)

    Best Regards,
