RadDataGrid detect column click

[Mark]

Hi,

I have some rather special display requirements on data in my RadDataGrid.  While I'd love to let RadDataGrid handle the sorting I think I need to populate the grid in the order I'd like.

My question is can I detect via an event or something when a user changes the sort and direction on a particular column?  If so... how?

Hello Mark,

You could detect whether a column sort action is executed through the ColumnHeaderTap Command of the DataGrid. You could create a custom ColumnHeaderTap command as described here: https://docs.telerik.com/devtools/universal-windows-platform/controls/raddatagrid/features/commands/datagrid-columnheadertapcommand.

In addition, in the Execute method you could access the Column and its SortDirection. Check below a quick example:

public class CustomColumnHeaderTapCommand : DataGridCommand
{
    public CustomColumnHeaderTapCommand()
    {
        this.Id = CommandId.ColumnHeaderTap;
    }

    public override bool CanExecute(object parameter)
    {
        var context = parameter as ColumnHeaderTapContext;
        // put your custom logic here
        return true;
    }

    public override void Execute(object parameter)
    {
        var context = parameter as ColumnHeaderTapContext;
        var sortDirection = context.Column.SortDirection;
        this.Owner.CommandService.ExecuteDefaultCommand(CommandId.ColumnHeaderTap, context);
        // put your custom logic here
    }
}

I hope this would be of help.
