What I'm doing in my code is generating a lot of RadChartView objects, saving them to disk, and then trying to dispose of the chart object. If I attempt to just do a chart.Dispose() when I'm done with the chart, memory related to the series data never gets released. If I clear the series' data points myself, then memory is freed when I finally do the chart.Dispose. Rename the attachment to (.7z) to see my example project. 

First I admit that I'm a newbie regarding UI design in Win8.1 - last time I did UI it was in the time of VB6 - so I may make stupid mistakes. But I've now played around for more than 4 hours, searching this forum and google'd a lot and I don't find some answers.

I'm working on VS2013, uptodate Telerik for WinForms, Win8.1 64 bit. My application is a simple test application, no custom code, just using the VS design view and Telerik UI elements. The png/icon I use are from "icon8.com" - downloaded in various pic sizes, currently I'm using the 50x50 pixel size. I imported the stuff into the resources file AND I also used a ImageList property after my first run didn't work out.

My requirement: simple. A good looking button with a simple image on it. Nothing fancy.

What I learned: if I use the image property, the image is not rescaled to the button size.
=> What I don't understand: what's the meaning of the "ImageScalingSize" parameters? I can't find an explanation in the documentation, and I don't see any effect on the bitmap if I change values (using the image property). Is there any other component using it? Should they rescale the image?

What I tried: I used (both the images from the resource file as well as the image from the ImageList) at the BACKGROUNDIMAGE parameter and IN BOTH CASES the image doesn't shop up on a Telerik RadButton. If the use the normal Windows Forms button, the image shows up. I have no idea why this won't work. Is it something with the resolution, the color depth in the PNG, the transparency setting? I tried various scaling settings (tile, stretch, center, zoom), no effect. I have no clue.

Regarding "SmallImageList": I haven't found any explanation when the SmallImageList is used. Propably a newbie question - any doc on this?

Kind regards,
Andrew

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,
Fawzieh
