Hi,
I'm trying to print/preview the complete results from a merge - the code below only outputs the currently selected merge record. I can scroll thru all merged records on screen but not print or preview the "whole" document. Dim provider As IDocumentFormatProvider = New DocxFormatProvider()
                Dim openDialog As New OpenFileDialog()
                openDialog.InitialDirectory = Session.WorkFolder & "\letters"
                'openDialog.Filter = "Documents|*.docx"
                openDialog.Multiselect = False
                Dim dialogResult As DialogResult = openDialog.ShowDialog()
                If dialogResult = System.Windows.Forms.DialogResult.OK Then

                    Using stream As Stream = openDialog.OpenFile()
                        RichTextEditor.Document = provider.Import(stream)
                    End Using

                    RichTextEditor.Document.MailMergeDataSource.ItemsSource = WkLetters
                    RichTextEditor.UpdateAllFields(FieldDisplayMode.Result)
                    RichTextEditor.MailMerge(True)

RichTextEditor.PrintPreview

                End If



Any help would be greatly appreciated.

Regards,

Lee.

Does anyone have any ideas what might be causing this error?

System.NotSupportedException occurred
  HResult=-2146233067
  Message=CultureInfoConverter cannot convert from (null).
  Source=System
  StackTrace:
       at System.ComponentModel.TypeConverter.GetConvertFromException(Object value)
  InnerException: 
My code looks like this:

If you copy a hyperlink from Outlook (or any Office app I expect) and paste it into a RichTextEditor box then try to modify the text... the control will crash.

To duplicate this bug:

1. Create a hyperlink in Outlook to \\server\folder1\folder2\folder3\somefile.txt

2. Copy the hyperlink and paste it into a RichTextEditor box.

3. Place your caret after the \ before somefile.txt

4. Press backspace until the control crashes (takes less than 20)

The control will start to act very weird with overlapping text before it finally crashes with the following error:

-----------------
Index was out of range. Must be non-negative and less than the seize of the collection.

I've tried setting AutoInsertHyperlinks to false but it still crashes.  Any ideas?

Thanks!

I have a radChartView and also a radGridView. I want to put Chart View on new row of Grid View. How can I perform this ?
here is my Chart View sample data code :

I try this code but a row was added without any value :

hi,

i am trying to inherit the RadGridView control and create a predefined list of columns.

if i create the columns in the constructor of the control and using it in a form (winform app), the visual studio designer will add the same columns a second time from the InitializeComponent() method.

what is the suggested way to do this?

thank you,
alez

Why deleted my post? I need the help! Please! How to change background color item, where value = 1?

I am vs 2010 user and vb developer. I have seen Telerik Rad Controls and how they perform and can only say that this is an amazing developer's tool! My problem though, is the fact that I already have 90% of my vb application in vs2010 designed using winform controls and was wondering whether there was an easy way to convert the already existing controls and forms to telerik?

Thanks,

Hello

I use the RadRichTextBox component (version 2014.1.402.40)

It's works with other source, but one specific source create this problem.


My simple code :

var htmlProvider = new HtmlFormatProvider();
radRichTextBox1.Document = htmlProvider.Import(mail); // ERROR / IndexOutOfRangeException

The HTML Source :

<html><head></head>
<body style = 'font-family:Arial, Helvetica, sans-serif; font-size:12px;'>
Bonjour,
<br><br>
<br><br>
<br><br>

<table border=0 style = 'font-family:Arial, Helvetica, sans-serif; font-size:12px;font-weight:bolder;'>
<tr>
<td rowspan=4 style="width:80px;"></td>
