Invisible the Group Drop Down

[Ching-Yen]

hi,

When we select the style of the PanelBar to OutlookNavPane, it will show a "group drop down" where the user can "add/remove" button...

May I know how can we hide this button (I do not want the user to edit the layout)

Please advice.

Hello Ching-Yen,

Thank you for writing.

You can hide the button in the OutlookNavPane view using the line below, assuming your RadPanelBar control is named radPanelBar1:

((

RadPanelBarOverFlow)radPanelBar1.RootElement.Children[0].Children[0].Children[1]).DropDownButton.Visibility = ElementVisibility.Collapsed;

I hope this helps. If you have any additional questions, please contact me again.


Best wishes,

Hello Ching-Yen,

Just a quick follow up on the RadPanelBar code I sent you to hide the button.

In order to make sure the button does not appear in certain scenarios, please subscribe to the ControlAdded event of the RadPanelBar, and set the visibility of the button to Hidden (as opposed to Collapsed in the code I sent you before). You have to set the Visibility of the button to Hidded in the form constructor.

Please use the code below:

private

void Form1_Load(object sender, EventArgs e)
{
radPanelBar1.ControlAdded += new ControlEventHandler(radPanelBar1_ControlAdded);

((RadPanelBarOverFlow)radPanelBar1.RootElement.Children[0].Children[0].Children[1]).DropDownButton.Visibility = Telerik.WinControls.ElementVisibility.Hidden;

}

void

radPanelBar1_ControlAdded(object sender, ControlEventArgs e)
{
((RadPanelBarOverFlow)radPanelBar1.RootElement.Children[0].Children[0].Children[1]).DropDownButton.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
}

If you have additional questions, please contact me again.
