In My Project I need to Emabad many types of documents Like word ,excel,pdf ,picturs ..
there is a way to use teleik control to support this kind of solution.

Hello,

In Telerik RadControls for WPF we have a RadRichTextBox control that supports importing, editing and exporting.xaml, .html, .rtf and .docx. You can find more information about it here.
When it comes to PDF files, you can use the RadPdfViewer. More about it you can read here. 
Currently, we do not have a controls that support Excel, but there are several ways to embed it in WPF without using Telerik RadControls.
Displaying images in WPF is a simple task that you can read more about here. If you need a control that edits images in WPF I would suggest you to check the RadImageEditor's documentation.

Regards,
Ivo
