Hi,

I remember already asked this but don't remember the thread so here we go,
I have a RadComboBox in one of my column.

When I scroll the combobox, it is dynamically changeing the widh if the ComboBox and this gives a bit of sickness
Is there a way to say to the RadCombobox that it must stay teh samw witdh means, the width if the longer line in the RadComboBox ?

Thank you

Hello Marc Roussel,

Probably the workaround was to set the Width of the RadComboBox via the EditorStyle of the combo column:

<telerik:GridViewComboBoxColumn  ItemsSourceBinding="{Binding AvailableCountries}"  DataMemberBinding="{Binding CountryID}"
    Header="Country"
    DisplayMemberPath="Name"
    SelectedValueMemberPath="ID">
    <telerik:GridViewComboBoxColumn.EditorStyle>
        <Style TargetType="telerik:RadComboBox">
            <Setter Property="Width" Value="200" />
        </Style>
    </telerik:GridViewComboBoxColumn.EditorStyle>
</telerik:GridViewComboBoxColumn>

However my RadComBoBox is added by C# code behind at runtime.
Do you have the equilavent in C# ?

Hello Marc Roussel,

The code will look something like this:

void clubsGrid_DataLoaded(object sender, EventArgs e)
{
    var comboColumn = this.clubsGrid.Columns["CountryID"] as GridViewComboBoxColumn;
 
    var style = new Style()
    {
        TargetType = typeof(RadComboBox)
    };
    style.Setters.Add(new Setter()
    {
        Property = RadComboBox.WidthProperty, Value = 200
    });
    comboColumn.EditorStyle = style;
}

Hi,

Thank you for the hint.
However, this is causing some trouble as having a fixed width makes some value in the combobox not entirely visible and making my combobox larger isn't an option.  What it must do in fact is having it autowidth as it does actually making the ComboBox the widh of the longer value in the list but stay that width when scrolling because there's no point of having the width of the ComboBox readapting according to what we can SEE.

So do you have any property to set the comboBox to audowidth but not AUTOWIDTH during the scrolling ?

Hi Marc Roussel,

I agree that this is not expected as the RadComboBox does not behaves the same when put outside the gridview.

I have logged the problem in our public issue tracking system and you can track its progress here.

I have updated your Telerik Points
