Hello Petr,
We usually do have an event that fires when the DataGrid generates columns automatically. However, this hasn't been implemented in UWP's DataGrid yet. You could use the Columns.CollectionChanged event in a similar fashion, but I have a better idea.
I have just realized you might be happy with just disabling IsCaseSensitive for all the TextFilterControls in the DataGrid. You can accomplish this without using a custom "MyFilterControl" or the "ColumnMarker"attached property.
Let's edit the previous example I sent.
Updated Example
Step 1. Remove the columns and go back to AutoGenerateColumns=True (the default):
<grid:RadDataGrid x:Name="DataGrid"
ItemsSource="{Binding Employees}">
<grid:RadDataGrid.Commands>
<local:CustomFilterButtonTapCommand />
</grid:RadDataGrid.Commands>
</grid:RadDataGrid>Step 2. Delete ColumnMarker and MyFilterControl classes
Step 3. Update the CustomFilterButtonTapCommand class to the following:
public class CustomFilterButtonTapCommand : DataGridCommand
{
public CustomFilterButtonTapCommand()
{
this.Id = CommandId.FilterButtonTap;
}
public override bool CanExecute(object parameter)
{
return true;
}
public override void Execute(object parameter)
{
var context = parameter as FilterButtonTapContext;
if (context.FirstFilterControl is DataGridTextFilterControl textfilterControl1)
{
textfilterControl1.IsCaseSensitive = false;
}
if (context.SecondFilterControl is DataGridTextFilterControl textfilterControl2)
{
textfilterControl2.IsCaseSensitive = false;
}
this.Owner.CommandService.ExecuteDefaultCommand(CommandId.FilterButtonTap, context);
}
}I have attached an updated version of the demo so you can see this at runtime:
