Binding IsVisible (GridViewColumn) fails

[Stig-Arild Martinsen]

When binding the IsVisible property (GridViewColumn) we get the error message AG_E_PARSER_BAD_PROPERTY_VALUE.

Examplecode:

<UserControl.Resources> <test:ColumnConfiguration x:Key="Config" /> </UserControl.Resources> <telerikGrid:RadGridView x:Name="grdTest">

<telerikGrid:RadGridView.Columns>

<telerikGrid:GridViewColumn IsVisible="{Binding CaseNumberIsVisible, Source={StaticResource Config}}">

<telerikGrid:GridViewColumn.Header>

<TextBlock Text="{Binding ColumnName, Source={StaticResource Config}}" />

</telerikGrid:GridViewColumn.Header>

</telerikGrid:GridViewColumn>

</telerikGrid:RadGridView.Columns>

</telerikGrid:RadGridView>

The value we're binding against is a bool.

Do we have to set this in code only? We're using the MVVM pattern and would like to avoid code for this.

Hi,

Binding on properties of non control elements is not supported in Silverlight 3 - Microsoft promised fix for this for Silverlight 4. The only way I can suggest you at this moment is to change this programmatically.

Thanks for fast reply. We'll have to do it programmatically then.

In Silverlight 4 persiste this problem?
