How to fire an event after filtering GDBG?

[Frank Lin]

I added a gridFilterBar to a GDBG. Now I want to show a message of currentcell after filtering. Which event should I fire? The filterbar.FilterBarTextChanged event is fired before the GDBG is filtered.

Right now there is no event raised after the filter. We will add one.

For the time being, to catch this action, you would need to derive GridDataBoundGrid and override OnCurrentCellClosedDropDown. In the override, call the base class, and then you could do your ''after filter'' work as the filtering is completed by this time. Or, you could raise an event at this point so any listener to the event could act on your custom "AfterFilter" event.

Here is a derived class:

 public class MyGridDataBoundGrid : GridDataBoundGrid
 {
	protected override void OnCurrentCellCloseDropDown(Syncfusion.Windows.Forms.PopupClosedEventArgs e)
	{
		base.OnCurrentCellCloseDropDown(e);
		if(this.CurrentCell.RowIndex == 1) //filter row
		{
			Console.WriteLine("After filter, there are {0} rows in grid.", this.Model.RowCount);
		}
	}
 }

Hi,Clay
Thanks for your answer.
Actually, the GDBG OnCurrentCellCloseDropDown event isn''t overridable. There is an error to override
Protected Overrides Sub oncurrentcellclosedropdown(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.PopupClosedEventArgs).

Is there any other solutions? Actually, it''s absolutely necessary in my applicaton to fire an event and calculate remaining records after filter.

That method is overridable. Here is a class that I added to the FilterBarSample and it worked as expected for me.

Imports Syncfusion.Windows.Forms.Grid
Public Class MyGridDataBoundGrid
    Inherits GridDataBoundGrid



    Protected Overrides Sub OnCurrentCellCloseDropDown(ByVal e As Syncfusion.Windows.Forms.PopupClosedEventArgs)
        MyBase.OnCurrentCellCloseDropDown(e)
        If Me.CurrentCell.RowIndex = 1 Then '' filter row
            Console.WriteLine("After filter, there are {0} rows in grid.", Me.Model.RowCount)
        End If
    End Sub
End Class

If you do not want to do this, you can wait until the next release (I do not know when it will be available, but it is in the works). We have added an event, FilterBarFilterCompleted, that is raised after the filter has been completed.
