[Solved] How to use FilterDescription in MVVM Pattern

[Jebouy]

Hi,

I am using MVVM pattern. I want to clear the Grid Filter on a button click.

[Rossen Hristov]

Hello jeb tom,

The only way to do this would be to attach to the button's click event and clear the GridViewDataControl.FilterDescriptors collection.

        private void Button_Click(object sender, System.Windows.RoutedEventArgs e)
        {
            this.playersGrid.FilterDescriptors.Clear();
        }

I hope this helps.

All the best,

Hi, 


  I am using MVVM pattern. we are not using the code behind.  So i need to clear the FilterDescriptor in the View Model.

Hi jeb tom,

The only way  you can do this is if you bind the grid to a QueryableCollectionView and create a Command that will operate directly on its filters.

Please, see the sample project attached. It can serve as a base and you can build upon it.

is this solution compatible with the last telerik silverlight version 2010 q3?

thanks

Hi Giovanni,

I believe that there is no reason not to be so.

But my suggestion would be to download the sample project, update the binaries and try whether it works just to make sure.
