Hi - I'm trying to print silently to the default printer though either the the radPDFViewerNavigator print button or the radPDFViewer default context menu.

For the radPDFViewerNavigator print button click event, I have the following:
me.RadPdfViewer1.Print(False)

This causes the document to print directly to the default printer but then right after that it still brings up the print dialog box.  Is there any way to keep the dialog box from showing?

As for the context menu print option, I can't seem to find a way to get the click event of this in order to override showing the print dialog box.

Any assistance on this will be greatly appreciated.

I am working on a Windows Forms Application that automatically loads a PDF file and then scrolls through the pages.  I am using 2 timers, one to scroll the page, and the other to check for a new version of the PDF file.  When I find a new version of the PDF file, I unload the current file and then load the new file.  All of this appears to work.  The problem is that the document does not appear unless I click on the form.  I can see the scroll bar moving.

Here is the subroutine that loads the document:

    Private Sub LoadPDFFile()

        If File.Exists(My.Settings.PDFFileName) Then
            mCurrrentFileInfo = My.Computer.FileSystem.GetFileInfo(My.Settings.PDFFileName)

            If PdfViewer.IsLoaded Then
                PdfViewer.UnloadDocument()
            End If

            PdfViewer.LoadDocument(My.Settings.PDFFileName)
            PdfViewer.PdfViewerElement.GoToPage(1)
        End If

    End Sub


OS: Windows 8
.Net 4.5
PDFViewer Version: 2014.2.715.40

I am experimenting with an application that will give me CPU Usage, Memory Usage, and I want to expand it from there. Right now it goes to two Text Boxes. I combined it into the first text box 

How do I display each value in two GridView Columns?

Here is what I have now;

Hi,

I use telerik Version 2011.1.411.2 (Runtime 2.0.50727).

I added a new colum in my database schema (for information double d_Value),

Can you explain how can I do ?

In advance, Thanks,
Richard.

Hello to all!

I've a GridViewMaskBoxColumn, where float are displayed using the exponental notation.  When I try to change a cells value, I can put the wished values, but when I leave the editor, the application crashs (even if I put only a '0')

The crash happens immediately after leaving the 'CellEndEdit'.

What went wrong in my source?

Thanks for your help!

I  have  Telerik winforms Q3 2011 SP1 version. I want to print a gridview but I didn't find RadPrintDocument. Is there any way gridview printing.

I need to disable the radbutton just before the click event is fired, and finally resume its enabled state after the click event.
I tried to create a property like this in my CustomRadButton:

But in debug I found out that the base.OnClick(e); event is asynchronous.

Can you suggest something to solve my problem?

Thanks
