Hello,
I'm using dotnet 3.5, WPF.
XP pro SP3.
IE6.0.2900
RadControls_for_WPF_2009_1_0526_TRIAL
C#

I have created a simple RadGridView  with a GridViewComboBoxColumn column.
I have added a combobox "DataTemplate" so that the column cells will look like a combo, and not just
when pressing on one of the cells.

In the constructor of the window1, I call FillStatusComboColumn() to fill the combo with possible values.

*** The problem is that using the "DataTemplate" in the XAML causes the values in the
combobox to disappear. ***

Any ideas ?

Thanks

E. S

<telerik:RadGridView  Name="RadGridView1"
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
AutoGenerateColumns="False"
ShowGroupPanel="False"
IsFilteringAllowed="False">
<telerik:RadGridView.Columns>
 <telerik:GridViewComboBoxColumn UniqueName="Status"
                                 HeaderText="STATUS">
 <telerik:GridViewColumn.CellTemplate>
   <DataTemplate>
      <ComboBox />
   </DataTemplate>
</telerik:GridViewColumn.CellTemplate>
</telerik:RadGridView.Columns>
</telerik:RadGridView>
 

private void FillStatusComboColumn()
{
var comboColumn = (Telerik.Windows.Controls.
GridViewComboBoxColumn)RadGridView1.Columns["Status"];
comboColumn.DataMemberBinding = new Binding("ActivityType");
comboColumn.ItemsSource = GetActivityTypes();
comboColumn.DisplayMemberPath =
"Name";
comboColumn.SelectedValueMemberPath =
"ID";
}

public class ActivityType
{
public string Name
{
get;
set;
}

public int ID
{
get;
set;
}

}

private System.Collections.IEnumerable GetActivityTypes()
{
List<ActivityType> ActivityTypes = new List<ActivityType>();

ActivityTypes.Add(new ActivityType() { ID = 0, Name = "" });
ActivityTypes.Add(new ActivityType() { ID = 1, Name = "Val1" });
ActivityTypes.Add(new ActivityType() { ID = 2, Name = "Val2" });
ActivityTypes.Add(new ActivityType() { ID = 3, Name = "Val3" });

return ActivityTypes;

}

Hi Erez,

When you define CellTemplate you need to fill your combo - column ItemsSource will work only for automatically generated combo in edit mode. The grid cannot know what kind of controls you have defined in your template and that is why cannot fill/databind these controls.
