Cannot add Column Dynamically

[om]

I just started using Telerik Grid instead of MS based Grid.
I just tried to Add and clear columns dynamically into the grid but I couldn't find the appropirate functions in intellisense.
I tried "this.radResult.Columns.Add(dyncol)" but, I Couldn't find "Add" in intellisense, couldn't find "Clear" method in intellisense as either.

        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="1*" />
        </Grid.ColumnDefinitions>

        <!-- Filtering ToolBar -->
        <RadNav:RadToolBarTray Grid.Row="0" Grid.Column="0" Style="{StaticResource style_DataGridRadToolBarTray}">

                </Button>
            </RadNav:RadToolBar>
        </RadNav:RadToolBarTray>

        <!--ItemsSource="{Binding Path=Items, Mode=TwoWay}"-->
        </RadGrid:RadGridView>
    </Grid>

</UserControl>

 

 

 

 

 

At code behind side I am using following namespaces:

 

 

 

 

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

// Telerik using
using Telerik.Windows;
using Telerik.Windows.Data;
using Telerik.Windows.Controls;
using Telerik.Windows.Controls.GridView;
using Telerik.Windows.Controls.GridView.Cells;

// add using
using System.Collections.ObjectModel;
using System.Windows.Browser;
using System.ComponentModel;
using System.Collections;
using System.Windows.Controls.Primitives;

 

 

 

 

void tabPreview_Loaded(object sender, RoutedEventArgs e)
{
    BuildColumns();
}

private void BuildColumns()
{
   this.radResult.Columns.Clear(); //<-- This method doesnt show in intellisense, neither Add method will show up here
}

Am I doing anything wrong here?
