Avoid Button Click close DropDown content in DropDownButton

[Daní]

Hello,

I'm using a RadRibbonDropDownButton with KeepOpen property set to false, so, whenever user cliks outside the drop dow content it closes. Inside the dropdown content I have a RadRibbonButton, clicking on this button causes a popuo to be shown, but popup never gets visible beacause RadRibbonButton clik forces the drop down to close. How can avoid the RadRibbonButton closing the dropdown content?

thanks.

Any help?

Hi Daní,

Unfortunately, I am unable to reproduce this issue showing a MessagBox. Could you please examine my test project and let me know if I am missing something?

Kind regards,

Hi Peter,

I meant showing a popup, a telerik popup. Please replace the DropDrownButton.DropDownContent in your example by the next xaml:

<StackPanel>

                                <Rectangle Fill="DeepSkyBlue" Width="100" Height="30" />
                                <telerik:RadRibbonButton x:Name="ShowPopupButton" Content="Show Popup" Click="RadRibbonButton_Click"  />

                                <Rectangle Fill="DeepSkyBlue" Width="100" Height="30" />
                                <telerik:Popup x:Name="MyPopup" CloseOnOutsideClick="True" Owner="{Binding ElementName=ShowPopupButton}" Placement="Bottom">
                                    <TextBlock FontSize="32" Text="Hello World!!!" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                                </telerik:Popup>
                            </StackPanel>

An on the RadRibbonButton click event handler, please replace the code by the next one:

private void RadRibbonButton_Click(object sender, RoutedEventArgs e)
        {
            MyPopup.IsOpen = true;
            //MessageBox.Show("Popu shown!");
        }

You will see that MyPopup never is shown. Of course, setting KeepOpen property to true on RadRibbonDropDownButton makes the popup to be shown when clicking on RadRibbonButton

Hi Peter,

Any advice about this issue? Or maybe what I'm trying to do is not possible and I must use a RadWindow in place the Telerik Popup?

Thanks.

Hi Daní,

You can play with the Closed and Opened events of the Popup in conjunction with the KeepOpen property of the button like so:

private void RadRibbonButton_Click(object sender, RoutedEventArgs e)
        {
            this.button.KeepOpen = true;
            MyPopup.IsOpen = true;
        }

        private void MyPopup_Opened(object sender, RoutedEventArgs e)
        {

        }

        private void MyPopup_Closed(object sender, RoutedEventArgs e)
        {
            this.button.KeepOpen = false;
            this.button.IsOpen = false;
        }

All the best,
