CRXPF0009 - AutoWidth and relative column width are used together

• Feb 14, 2023

Severity: Error

The analyzer detects that you use relative (star) values to specify a column’s Width property, and the TableView.AutoWidth or TreeListView.AutoWidth property is set to true. In this case, the GridControl does not apply relative column widths.

Examples

Invalid Code

XAML

<dxg:GridControl ...>
    <dxg:GridControl.View>
        <dxg:TableView AutoWidth="True" .../>
    </dxg:GridControl.View>
    <dxg:GridColumn FieldName="FieldName1" Width="3*"/>
    <dxg:GridColumn FieldName="FieldName2" Width="2*"/>
    <dxg:GridColumn FieldName="FieldName3" Width="*"/>
    <!-- ... -->
</dxg:GridControl>

Valid Code

XAML

<dxg:GridControl ...>
    <dxg:GridControl.View>
        <dxg:TableView AutoWidth="False" .../>
    </dxg:GridControl.View>
    <dxg:GridColumn FieldName="FieldName1" Width="3*"/>
    <dxg:GridColumn FieldName="FieldName2" Width="2*"/>
    <dxg:GridColumn FieldName="FieldName3" Width="*"/>
    <!-- ... -->
</dxg:GridControl>

How to Fix

Set the TableView.AutoWidth or TreeListView.AutoWidth property to false if you use relative (star) values to specify a column’s Width property.
