[Solved] Unload RowDetails ?

[Jim]

I have data that I dynamically load when a user selects a particular row in my gridview.  I have defined a RowDetailsTemplate and everything seems to work very nicely.

Somewhat arbitrarily an event occurs that causes much of my data that is showing in the row details to become invalid.  Is there a way to "invalidate" or "unload" the associated row details for a gridview?

I have an alternative solution to my problem but it seems heavy handed if I am simply missing some piece of existing functionality.

Thanks !

Hi Jim,

If you assign null or another template the old DetailsElement will be unloaded and the new one will be loaded. Which I think is what you are after.

private void Button_Click(object sender, System.Windows.RoutedEventArgs e)
{
    // You can do it for the whole grid
    var template = this.clubsGrid.RowDetailsTemplate;
    this.clubsGrid.RowDetailsTemplate = null;
    this.clubsGrid.RowDetailsTemplate = template;

    // Or you can do it on a per row basis using the Row's DetailsTemplate property.
}

I have prepared a small sample project and attached it. I hope it helps. Let me know if this is not what you are after.

Kind regards,
