Adding Filter Descriptor shows Error

[azhar]

Hi Telerik Team,
        I tried to add FilterDescriptor for RadGridView, but it is not adding and shows an error message "The method or Operation is not implemented". Please let me know any other way to add FilterDesriptor or how to overcome this error.. I'll be thankful to you if given any good idea.

This is the code I've written...

For

 

 

Each d As FilterDescriptor In e.Added
          RadGridView1.FilterDescriptors.Add(New FilterDescriptor(d.Member.ToString, d.Operator, d.Value, False))
Next

I have installed Q3 version in my system.. Please Help..

Thanks and Regards,
Azharshah H

Hello azhar,

Make sure you are not using the System.Windows.Controls.FilterDescriptor.
You need to use Telerik.Windows.Data.FilterDescriptor.

Hi Veselin Vasilev,
I'm using Telerik.Windows.Data.FilterDescriptor only. I really don't know why I'm getting that error.

The Object Browser shows the following message when I Clicked "Go To Definition" on "FilterDescriptor".

Public Class FilterDescriptor

Inherits

Telerik.Windows.Data.FilterDescriptorBase

 

 

Member of

Telerik.Windows.Data

Hello azhar,

What exactly is e.Added? Can you give us the relevant code?

Hi Veselin Vasilev ,
This is the code I'm using....


Private

 

 

Sub Me_Filtering(ByVal source As Object, ByVal e As GridViewFilteringEventArgs) Handles Me.Filtering

 

 

 

Try

 

 

 

Me.FilterDescriptors.Clear()

 

e.Cancel =

 

True

 

 

 

For Each d As FilterDescriptor In e.Added

 

 

 

Me.FilterDescriptors.Add(New FilterDescriptor(d.Member.ToString, d.Operator, d.Value, False))

 

 

 

Next

 

 

 

Catch ex As Exception

 

MsgBox(ex.Message)

 

 

End Try

 

 

 

End Sub

Hello azhar,

Can you please explain what is the purpose of the code? Does the built in filtering does not work for you?
Why you cancel the event and then manually add the filter descriptors to the gridview?

All the best,

Hi Veselin Vasilev,
    I need to filter data along with empty rows. That was the sample application to add filter descriptor. i'll manually give empty value as d.Value to display Empty Rows along with Filtered Data..

Thanx and Regards,

Hi Veselin Vasilev,
I'll Use CompositeFilterDescriptor for that purpose.. But my problem is, I'm not able to add FilterDescriptor..

Hi Telerik Team,

I want to filter data and the filtered data should have empty rows. How to achieve it?
