Hello there,

I have changed the default Segoe font to Arial 9pt for my RadGridView using the IDE. But the drop-downlist of items in a GridViewComboBoxColumn does not follow and still displays as Segoe. There is no option in the IDE to alter it. I am trying to find out how to alter the font of the drop-down list in code please? (vb.net)

I imagine I could use VisualStyle builder but I cannot seem to export from that all the settings for a given off-the-shelf theme, and I do not havethe time to make a whole theme with all it's settings...

Thanks in advance

Hello Ian,

You can set a different font for the DropDown by subscribing to the CellEditorInitialized event as follows:

private void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
    var editor = e.ActiveEditor;
    if (editor != null && editor is RadDropDownListEditor)
    {
        RadDropDownListEditor dropDown = (RadDropDownListEditor)editor;
        RadDropDownListEditorElement element = (RadDropDownListEditorElement)dropDown.EditorElement;
        element.Font = // a font
        element.ListElement.Font = // a font
    }
}

Hope that helps
Richard

Dim editor = e.ActiveEditor
If editor IsNot Nothing AndAlso TypeOf editor Is RadDropDownListEditor Then
    Dim dropDown As RadDropDownListEditor = DirectCast(editor, RadDropDownListEditor)
    Dim element As RadDropDownListEditorElement = DirectCast(dropDown.EditorElement, RadDropDownListEditorElement)
    element.Font = New Font("Arial", 9)
    element.ListElement.Font = New Font("Arial", 9)
End If

Hi,

Glad that helped. Just one other thing. You may have already realised but it would be better to maintain a private member of the font that you need and assign that rather than create a new instance of the font each time CellEditorInitialized is raised.

Hope that helps

Hi there, I'm having the same issue, I've tested Richard Slade code, and it worked but when I type something in the autocomplete area the font changes again to the default value..

Any sugestion?

Hello Jose,

The observed behavior is expected, as the auto complete functionality has its own popup with its own ListElement in it, so you have to set the Font of the latter as well. Here is the modified snippet:
Font f = new Font("Consolas", 12);
private void radGridView1_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
    var editor = e.ActiveEditor;
    if (editor != null && editor is RadDropDownListEditor)
    {
        RadDropDownListEditor dropDown = (RadDropDownListEditor)editor;
        RadDropDownListEditorElement element = (RadDropDownListEditorElement)dropDown.EditorElement;
        element.Font = f;
        element.ListElement.Font = f;
        element.AutoCompleteSuggest.DropDownList.ListElement.Font = f;
    }
}

I hope that the provided information addresses your question.

Best wishes,
Stefan
