Grid for WPF

[ArijitM]

Hi, Iam working on WPF DataGrid (dev. by ComponentOne) with Visual Studio 2008. I wish to provide facility to
user to select "Columns" of a Table using ListBox(if possible, by clicking on Checkboxes within the ListBox) and
the Report will be generated for those selected "Columns" only. :rolleyes:Selection to be made at run time !

I have run the program on WPFDatagrid, but it is giving 2 errors.
i)Could not create an instance of type'StaticExtension'
ii)Cannot find the type 'VisibilityToBoolConverter'
I am sending the relevant XAML code as well as the VisibilityToBoolConverter.vb code
<XAML>
<CheckBox IsChecked="{Binding Visibility ,
Converter={x:Static local:VisibilityToBoolConverter.Default},
Mode=TwoWay}"/>
<TextBlock Text="{Binding Caption}"/>
</XAML>
<VisibilityToBoolConverter.vb>
Imports System
Imports System.Collections.Generic
Imports System.Linq
Imports System.Text
Imports System.Windows.Data
Imports System.Windows
Imports System.Globalization

Namespace NEW_WpfApplication_20_5_08
Public Class VisibilityToBoolConverter
Implements IValueConverter

Public Shared ReadOnly [Default] As New VisibilityToBoolConverter()

Public Function Convert(ByVal value As Object, ByVal targetType As Type, ByVal parameter As Object, ByVal culture As CultureInfo) As Object Implements IValueConverter.Convert
If TypeOf value Is Visibility Then
Return CType(value, Visibility) = Visibility.Visible
Else
Return Binding.DoNothing
End If
End Function

Public Function ConvertBack(ByVal value As Object, ByVal targetType As Type, ByVal parameter As Object, ByVal culture As CultureInfo) As Object Implements IValueConverter.ConvertBack
If TypeOf value Is Boolean Then
Return If(CBool(value), Visibility.Visible, Visibility.Collapsed)
Else
Return Binding.DoNothing
End If
End Function
End Class
End Namespace
</VisibilityToBoolConverter.vb>
Could somebody point out the error in my application ? Regards Arijit
