Add Button to Navigator

[Samantha]

Hello.  I would like to add a "Save As" button and an "Email" button to the RadPdfViewerNavigator.  Is this possible to do?

Hi Samantha,

Thank you for writing.

You can add custom buttons to the RadPdfViewerNavigator like this:

CommandBarButton btn = new CommandBarButton();
this.radPdfViewerNavigator1.CommandBarElement.Rows[0].Strips[0].Items.Add(btn);

You can remove and insert buttons also like with normal collection. You can also subscribe for the Click event of the button and change it's image.

I hope this helps.

A couple more questions related:
1.I added programmatically a button to the navigator bar. Where can I find the handler for the newly created button so I can add my code there?
2.How do you add to the new created button the save image?
3.I don't wish the users to add/modify the buttons they can see on the pdf navigator. What should I do to disallow this?

Hi TB,

Thank you for writing.

We will use the following code for reference:

CommandBarButton btn = new CommandBarButton();
this.radPdfViewerNavigator1.CommandBarElement.Rows[0].Strips[0].Items.Add(btn);

1. The button element has events just like other buttons do. The click event can be used as follows:

   btn.Click += btn_Click;

2. The button also has an Image property which you can change very easy:

   btn.Image = Image.FromFile("MyImg.png");

3. if you do not want your users to remove and add buttons you can hide the overflow button with the code below:

   this.radPdfViewerNavigator1.CommandBarElement.Rows[0].Strips[0].OverflowButton.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

I hope this helps.

This little trick:

this.radPdfViewerNavigator1.CommandBarElement.Rows[ 0 ].Strips[ 0 ].OverflowButton.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

needs to be included prominently in the docs for this control.  It was the first thing I wanted to do and I wasted a lot of time hunting it down here.

It is not exactly intuitively obvious that is the way to disable the customization menu.

How about a property at the top level ... AllowUserCustomization?

Hi Ken,

Thank you for replying.

Actually, we have documentation about RadCommandBar which is used in RadPdfViewerNavigator. For example you can see its structure here: Structure. And on the following url you can see how to use it at design time, which is very much similar to the approach in runtime: Design-Time. And here you can see how to modify the overflow button of each CommandBarStripElement.

I hope this helps.
