Question

i have a Telerik GridView with a ComboBox Column, while filtering in this Combobox an appending list dropped down.

RadDropDownList uses different popups for its default items representation and for its auto complete suggest items. Here is an example demonstrating how to change the font of both:

 void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
    {
        RadDropDownListEditor editor = e.ActiveEditor as RadDropDownListEditor;
        if (editor != null)
        {
            editor.DropDownStyle = RadDropDownStyle.DropDown;
            RadDropDownListEditorElement element = (RadDropDownListEditorElement)editor.EditorElement;

            element.VisualItemFormatting -= element_VisualItemFormatting;
            element.AutoCompleteSuggest.DropDownList.VisualItemFormatting -= element_VisualItemFormatting;

            //this handles the default drop down formatting - when you press the arrow key to open the drop down
            element.VisualItemFormatting += element_VisualItemFormatting;
            //this handles the suggest popup formatting
            element.AutoCompleteSuggest.DropDownList.VisualItemFormatting += element_VisualItemFormatting;
        }
    }

    void element_VisualItemFormatting(object sender, VisualItemFormattingEventArgs args)
    {
        args.VisualItem.Font = new Font("Arial", 16);
    }
