Hello
i am adding some comumns in my code behind to a radgridview
The problem i get is that these columns are not filterable neither groupable . I have some columns defnied in the xaml and these are filterable and groupable.

So i dont understand why the dinamicly created columns are not.

Here is my code

<telerik:RadGridView Name="GridViewListeConstituants" Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="3" Style="{DynamicResource RadGridViewStyle1}" HeaderRowStyle="{DynamicResource GridViewHeaderRowStyle1}"

Margin="5" ItemsSource="{Binding listeConstituants}" AutoGenerateColumns="False" >

<telerik:RadGridView.RowStyleSelector>

<telerik:ConditionalStyleSelector>

<telerik:StyleRule Condition="enCreation" Style="{DynamicResource RowEnCreationStyle}" >

</telerik:StyleRule>

<telerik:StyleRule Condition="enCreation=false" Style="{DynamicResource RowStandardStyle}">

</telerik:StyleRule>

</telerik:ConditionalStyleSelector>

</telerik:RadGridView.RowStyleSelector>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding LIBELLE}" Header="Libellé" HeaderCellStyle="{DynamicResource HeaderCellStyle1}">

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn DataMemberBinding="{Binding UNITE}" Header="Unité" HeaderCellStyle="{DynamicResource HeaderCellStyle1}">

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn DataMemberBinding="{Binding VALEURDEFAUT}" Header="Valeur par défaut" HeaderCellStyle="{DynamicResource HeaderCellStyle1}">

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn Header="Propriétés" HeaderCellStyle="{DynamicResource HeaderCellStyle1}" >

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<telerik:RadButton Name="ButtonProprietes" Content="{Binding StringPropriete}" Click="ButtonProprietes_Click_1"></telerik:RadButton>

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

foreach (CONTEXTE monContexte in listeContextes)

{

Telerik.Windows.Controls.GridViewCheckBoxColumn maColonne = new Telerik.Windows.Controls.GridViewCheckBoxColumn();

//Telerik.Windows.Controls.GridViewDataColumn maColonne = new Telerik.Windows.Controls.GridViewDataColumn();

maColonne.HeaderCellStyle = this.FindResource("HeaderCellStyle1") as Style;

maColonne.DataMemberBinding = new Binding("RowContextes[" + monContexte.LIBELLE + "]");

maColonne.Name = "C"+ monContexte.ID_CONTEXTE.ToString();

maColonne.Header = monContexte.LIBELLE;

maColonne.Width =100;

maColonne.TextAlignment = TextAlignment.Center;

maColonne.CellStyle = this.FindResource("CheckBoxCellStyle") as Style;

this.GridViewListeConstituants.Columns.Add(maColonne);

maColonne.IsCustomSortingEnabled = true;

maColonne.IsFilterable = true;

maColonne.IsGroupable = true;

maColonne.IsReorderable = true;

maColonne.IsSortable = true;

maColonne.IsThreeState = true;

maColonne.DataType= System.Type.GetType("Boolean");

//maColonne.

}

Any idea about what this isnt working?

After some test, it looks like the problem come from the fact i a am using a data row to bind the columns data.

if i try to add a column binded this way :

maColonne.DataMemberBinding = new Binding("RowContextes[mykey]");

it wont be groupable or sortable, but if it binded directly to a property:

maColonne.DataMemberBinding = new Binding("oneproperty");

it is groupable and filterable.

But i still need to create those columns from a collection or a dataRow or something containing multiples object. So how can i do this and keep the filterable and groupable thing?
