RadTabControl sets focus to RadComboBox on tabchange

[Prashant]

Hi All,

I have tabcontrols with two tabs and each tab has comboboxes. On initial load everything is working as expected but if i change tab automatically focus sets to combobo control. 

I want to prevent auto focus element tab onchange, please see below sample code to reproduce issue.

 

<telerik:RadTabControl>
            <telerik:RadTabItem  Header="Location">
                <telerik:RadTabItem.Content>
                    <StackPanel>
                        <telerik:RadComboBox Width="200" x:Name="item1" Height="50" IsEditable="True"   EmptyText="Select"  >
                            <telerik:RadComboBoxItem Content="Item 1" />
                            <telerik:RadComboBoxItem Content="Item 2" />
                        </telerik:RadComboBox >
                        <telerik:RadComboBox Width="200" x:Name="item2" Height="50" IsEditable="True"  >
                            <telerik:RadComboBoxItem Content="Item 1" />
                            <telerik:RadComboBoxItem Content="Item 2" />
                        </telerik:RadComboBox>
                    </StackPanel>
                </telerik:RadTabItem.Content>
            </telerik:RadTabItem>
            <telerik:RadTabItem Header="Asset Type" >
                <StackPanel>
                    <telerik:RadComboBox Width="200" x:Name="item3" Height="50" IsEditable="True"    EmptyText="Select" >
                        <telerik:RadComboBoxItem Content="Item 1" />
                        <telerik:RadComboBoxItem Content="Item 2" />
                    </telerik:RadComboBox>
                    <telerik:RadComboBox Width="200" x:Name="item4" Height="50" IsEditable="True"  EmptyText="Select" >
                        <telerik:RadComboBoxItem Content="Item 1" />
                        <telerik:RadComboBoxItem Content="Item 2" />
                    </telerik:RadComboBox>
                </StackPanel>
            </telerik:RadTabItem>
        </telerik:RadTabControl>

 

Any help would be appreciated,

Hi Prashant,

This is the default behavior of the RadTabControl when switching tabs. What you can try is to subscribe to the SelectionChanged event of the RadTabControl and focus the RadTabItem. You need to wrap it in a dispatcher so that you can prevent the RadComboBox inside, focusing when you focus a control outside the RadTabControl and focus the RadTabItem again.

private void RadTabControl_SelectionChanged(object sender, Telerik.Windows.Controls.RadSelectionChangedEventArgs e)
{
    Dispatcher.BeginInvoke((Action) (()=> {
        (sender as RadTabControl).Focus();
    }),DispatcherPriority.ApplicationIdle);
}
