Crash when editing pasted hyperlink text

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.

at System.ThrowHelper.ThrowArgumentOutOfRangeException()
   at System.Collections.Generic.List`1.get_Item(Int32 index)
   at Telerik.WinControls.RichTextEditor.UI.TextBlock.DrawRunGDI(Run run, RunLayoutInfo runInfo, Single fontSizeScale, PointF location, NativeTextRenderer renderer)
   at Telerik.WinControls.RichTextEditor.UI.TextBlock.DrawGdi(Single angle, Graphics nativeGraphics, Single fontSizeScale)
   at Telerik.WinControls.RichTextEditor.UI.TextBlock.PaintElement(IGraphics graphics, Single angle, SizeF scale)
...
-----------------

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

Thanks!

Custom RadGridView containing predefined columns

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

Convert Already Existing Winform components to RAD Controls

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

Can we filter the entire grid based on any child grid colum

Hi. i am quite new to telerik controls. i have a hierarchical datagrid where i am using a dataset to bind the grid that has two data table. Orders and OrderProducts. Order is parent grid and OrderProduct is child grid. Filter work well on child grid but it works on only child rows.

            ds.Tables.Add(dtProducts);
            dgOrders.DataSource = ds.Tables[0];
            GridViewTemplate template = new GridViewTemplate();
            template.DataSource = ds.Tables[1];
            dgOrders.MasterTemplate.Templates.Add(template);
            GridViewRelation relation = new GridViewRelation(dgOrders.MasterTemplate);
            relation.ChildTemplate = template;
            relation.RelationName = "OrderProducts";
            relation.ParentColumnNames.Add("OrderNumber");
            relation.ChildColumnNames.Add("OrderNumber");
