WPF gridcontrol best fit all columns

created 9 years ago

Hello,

How can I best fit all columns?  Currently, my users have to right-click a column heading and select Best Fit (all columns) . I thought the below xaml would solve the issue, but it doesn't apply best fit at run-time.  Also, i noticed that after the data is refreshed the best fit is lost; do i need to set best fit programmatically after best fit and if so could you please provide an example?  If needed see attached screen shot of what I'd like to do.

<dxg:GridControl x:Name="dgTest" AutoGenerateColumns="AddNew" EnableSmartColumnsGeneration="True" Grid.Row="2" SelectionMode="Cell" OptimizeSummaryCalculation="True" ClipboardCopyMode="IncludeHeader">            <dxmvvm:Interaction.Behaviors>                <behaviors:DynamicConditionBehavior/>            </dxmvvm:Interaction.Behaviors>                        <dxg:GridControl.View>                <dxg:TableView x:Name="view" AllowPerPixelScrolling="True" ShowTotalSummary="True" AllowEditing="False" ShowGroupPanel="False" BestFitMode="AllRows" />

Hi Jimmy,

Since the Best Fit feature requires a lot of resources, it may hang the application when the DXGrid control has a lot of data. So, the control doesn't perform best fit operations automatically. Thus, you need to call the TableView.BestFitColumns method manually when required. E.g., call it once the control's ItemsSource is changed.

Regards,
Alex

      Thanks Alexander for the explanation and suggestion.  With your explanation, I'll use it sparingly and play around with it to only make use where it makes sense.

          Just implemented it after my BindData method that sets the itemsource.  It works exactly as expected with not much performance issues.
          Thanks again Alexander.
