Custom Filtering Row Example

[Szymon Wantuch]

Hello,

I am currently trying to create custom filtering row as based on example in the documentation.
However, while the row displays nicely in designer, it never shows.

I've tracked problem to the grid's Loaded event: inside the handler when I use GetChildrenOfType<GridViewHeaderRow>() it returns nothing. VisualTreeHelper also shows children number as zero. How do I fix it?

Best Regards,

Hi Szymon Wantuch,

 Do you mean this example? We updated that particular example from our Q1 release and it has been reworked rather extensively.

The RadGridView's Loaded event fires before the GridView's visual tree has been completely built so that's why you can't find the GridViewHeaderRow. You're better off handling the RowLoaded event and checking if the loaded row is of type GridViewHeaderRow. If so, attach the filter row. You can examine the new version of the example for additional insight.
