Custom Filter over All Columns

[ITA]

Hi,

 

using GridViewControl with about 7 Columns. I like to add a custom filter over all columns by using a Textbox above the GridView.
How can i do this, is there an exmaple somewhere?

 

Thanks a lot

best regards

Hi Rene,

You can check the Search As You Type WPF Demo as a reference on how to filter from a TextBox outside RadGridView.

Hello Rene,

You can find the online demo. You can also check our online documentation where the filtering is explained in details.

Hi Dimitrina,

sorry works fine. But one Problem. I have a "telerik:GridViewImageColumn" in man GridView and i get an error in
"CustomFilterDescription" Klass.

public CustomFilterDescriptor(IEnumerable<Telerik.Windows.Controls.GridViewColumn> columns)
 {
           this.compositeFilterDesriptor = new CompositeFilterDescriptor();
           this.compositeFilterDesriptor.LogicalOperator = FilterCompositionLogicalOperator.Or;

           // ERROR !!!!!!!
           foreach (GridViewDataColumn column in columns)
           {
               this.compositeFilterDesriptor.FilterDescriptors.Add(this.CreateFilterForColumn(column));
           }
   }

 

Thanks
