I have a treeview that is dynamically populated with nodes.   I have enabled the default context menu for the treeview.  When I use the default context menu to delete a node, how do I get a reference to the radtreenode object that is being deleted?   There appear to be no standard event handlers for winforms treeview default context menus.

Thanks.

Calling BetFitColumns (or BestFit on each Column) is not working in ChildGrivdViewTemplates.  It just sets all Column Widths to some default width (i.e. 50).  I'm binding to a DataSet filled by a SqlDataAdapter.

2009Q2 (2009.2.9.729), VS 2005 (v8.0.50727.762 SP.050727-7600), .Net2 (2.0.50727), XP SP3, Core2Duo 2.99GHZ with 3GB.

I created a project that has a MDI frame and a form. I run it and open the form in the MDI frame. It looks fine if it is not maixmized. But once the form is maximized in the MDI frame, then there is a not usable gray color space on  the bottom and right side of the form. I placed a gridview and I maximized the form, then still there is a gray space on the bottom and left side. I see it only the form is maximized.

What is happening?

I am using Linq to pull data for grid, so properties has to be set by coding such as header text, cell format, and size.
I tried below code and it causes this error, "Object reference not set to an instance of an object."

Is there any way that I can set properties by coding before data is pulled?

RadPageView will be the successor of RadPanelBar and RadTabStrip by providing different views over a collection of pages. Each page is a stand-alone Panel where controls may be added through the Visual Studio Designer. The control is fully customizable yet greatly optimized for both memory consumption and performance. It will offer better item sizing and spacing, as well as extended orientation modes over the other two controls. Read more in the following blog posts:

• RadPageView – next generation WinForms navigation control
• RadPageView for WinForms: what’s inside?

What will happen to the old controls?

The old controls will be supported for at least one year after the release of Q2 2010. Users will nevertheless be encouraged to use RadPageView since it addresses the fundamental shortcomings of the previous controls.

Is upgrading to the new controls easy?

Upgrading from the old to the new control should be easy and painless, unless you have extended the previous controls with custom functionality. If this is the case, please contact Telerik support and we will help you move to the new version. We will also try to provide an automatic upgrade tool with Q2 2010 SP1.

Videos and instructions on how to upgrade from the old versions to the new control will be posted shortly.

How do I get support for the new controls?

To get technical support, either contact Telerik support or post in the PageView Forum.

Hi Support,

I update my project to Telerik Winform Q2 2010. I encounter a problem with the new release in my project when I sort (ascending or descending) a column and then drag the column to a new position.

You can reproduce this error in the Q2 2010 Demo.
1. Select Grid View - Populate with data - Data Binding
2. Sort the Contact Name column
3. Drag the Contact Name column between the Contact Title and Address column.

This is the exception detail I obtain in my code:

Hi guys,

I'm in the process of upgrading our application's telerik version from Q2 2009 to the latest version currently listed on your site.

The app uses quite a lot of RadGrids and RadRibbonForms which was customised extensively and isn't working anymore.

Is there any demo available that shows how the mdi works for the new version where clicking on the active document would change the ribbon menu to the active document's menu?

Hi -

I am trying to display a grid with no outer border (around the outside of the grid).

I Binged and searched several options, such as setting the BorderWidth = 0, but none of the things I tried actually removed the border.

Is there a way to clear the border?

If I do have to have a border, is there a way to make it rounded?

Thanks!
