[Solved] Am I going mad? MasterGridViewTemplate.ChildGridViewTemplates missing

Yeah that wasn't the best subject line ever.

OK so I've added a gredview to the form. Now I want to setup some hierarchy. Using the help as a guideline I'm looking for the MasterGridViewTemplate property in the properties - can't find it, so going to the property builder for the grid I look in there for the ChildGridViewTemplates, no luck with that either.

I'm using the 2010 Q2 SP1 version of WinForms....

Any ideas what is going on?

Regards,

Jon

Treeview DefaultContextMenu event

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.

BetFitColumns and BestFit Not Working in ChildGrivdViewTemplates

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.

[Solved] Maximized form in a MDI Frame

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?

[Solved] Define Column header text

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?

Private Sub frmEmployee_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

InitializeGridView()

End Sub

Public Sub InitializeGridView()

Me.rgvEmployee.Columns("EMP_ID").HeaderText = "Man"

End Sub

Panelbar obsolete as of Q2 2010. Replaced by RadPageView

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:

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.
