How to set focus on a ComboBox cell and open the combo box.

[Jon]

Hi..
I have a button that adds a new row to the grid. I need to set focus to the new row and open the first cell - which is combo box and set focus.
I have tried the following but it does not work.. any ideas?  thanks

 

this.gridPO_det.ScrollIntoViewAsync(new_det

 

, (f) =>

{

 

GridViewRow row = f as GridViewRow;

 

 

if (row != null)

 

{

 

GridViewCell cell = row.Cells[0] as GridViewCell;

 

cell.BeginEdit();

Dispatcher.BeginInvoke(

new Action(() =>

 

{

((

RadComboBox)cell.GetEditingElement()).IsDropDownOpen = true;

 

}));

}

});

Hello Jon,

You may create a separate style for the editor element in the GridViewComboBoxColumn. For example:

Window.Resources>
    <Style x:Key="ComboBoxEditor" TargetType="telerik:RadComboBox">
        <Setter Property="IsDropDownOpen" Value="True" />
    </Style>
</Window.Resources>

<telerik:GridViewComboBoxColumn Header="Nationality" 
EditorStyle="{StaticResource ComboBoxEditor}"                                             DataMemberBinding="{Binding CountryID, Mode=TwoWay}"                                                DisplayMemberPath="Name"                                                                                                                    SelectedValueMemberPath="ID"                                               
SortMemberPath="Name">
