Problem with radtreelistview custom filtering

[Sharada]

Hi,
I am using custom context menu to apply flter on hierarchical radtreelistview.
I am binding the radtreelistview to an ObservableCollection<>.
In order to apply filter, I am using the below code

 

private

 

 

void RadMenuItem_Click(object sender, Telerik.Windows.RadRoutedEventArgs e)
{
    if ((sender as RadMenuItem).Header.Equals("Filter By Selection"))
        { 
            FilterDescriptor descriptor = new FilterDescriptor();
            descriptor.Member = strClickedColumn;
            descriptor.Operator = FilterOperator.IsEqualTo;
            descriptor.Value = strClickedColumnData;
            this.RadTreeListView1.FilterDescriptors.Add(descriptor);
        }
}

But i am not getting the desired results.
Instead,the radtreelistview displays 0 items.
Can you please share a sample project which provides a working solution for custom filter?

Hello Sharada,

I have tried to reproduce the issue you specified, but I was not able to. I am sending you the sample project I used for testing it. Please take a look at it and let me know in case of any discrepancies according to your requirements. Feel free to change the application in the way you want and send it back if necessary.
 

All the best,
