MultiSelectComboBox filter row editor wrong items order

Question

Hi,I have in my grid GridMultiColumnDropDownList column with MultiSelectComboBox filter row editor. But in the filter row editor there is wrong items order, I need A-Z order. It seems that the order is based on ValueMember not on DisplayMember, what would make more sense.Please check attached sample project and screenshot.Thanks!Attachment: data_81d6a564.zip

Hi Ondrej Svoboda, 
 
Thank you for using Syncfusion controls. 
 
In ComboBox controls items are generated by added orders only. In FilterRow, we have used the ComboBoxAdv control. So, it shows the orders based on manner, which you added in its itemsSource. 
 
Now, we have ordered this by apply the sorting for comboBoxItems. We have achieved this by overriding the GridFilterRowMultiSelectRenderer. 
 




Grid.FilterRowCellRenderers.Remove("MultiSelectComboBox"); 
Grid.FilterRowCellRenderers.Add("MultiSelectComboBox", new GridMultiSelectComboBoxRendererExt()); 
 
public class GridMultiSelectComboBoxRendererExt : GridFilterRowMultiSelectRenderer 
{ 
 
    public GridMultiSelectComboBoxRendererExt() : base() 
    { 
    } 
 
    public override void OnInitializeEditElement(DataColumnBase dataColumn, ComboBoxAdv uiElement, object dataContext) 
    { 
        base.OnInitializeEditElement(dataColumn, uiElement, dataContext); 
        SortDescription sd = new SortDescription("DisplayText", ListSortDirection.Ascending); 
        uiElement.Items.SortDescriptions.Add(sd); 
    } 
}
