Unable to add column names to child/parent template in Hier. Grid

Hi,

I am getting an error throw when I try to add the column names to the child and parent relations in a hierarchical gridview. I am using your WINForms sample, except that I changed the datasource to Entity Framework 4 .edmx, and am using .Net 4.0 on a WIN7 OS. I've attached 2 files, 'Form1' shows the results. All works fine, except the child grids are not linked to the ContactID on the grid (the relationships are defines properly in the .edmx). 'Relations' shows the results I'm getting when I try to set them in the properties window.

Thanks

Steve

[Solved] Context Menu's

Hello

Can anybody tell me how I can detect where the context menu is clicked, in particular I'm looking to detect a right click in the blank space below rows (see attached file.)

The following snippet stops the right clicking on the header, and allows right clicking on a row, but I can't seem to find out when the "whitespace" is clicked? - Any clues?

Many thanks

Terry

Hi,

I want to add the some Combobox,TextBox and Button on the DockTabStrip or Top of the ToolWindow of RadDock Control.
But i am not getting any way to do this.

And my anathor problem is that i rounded the shape of the e.DockWIndow with FIllPrimitive and BorderPrimitive properties that rounded
the upper portion of the ToolWindow but back portion of the control is looking odd/rectangle.

The Snap Shot of my problem with code over it is attached with this thread (dock.png).

Please review this problem as soon as possible.

private void radDock1_DockStateChanged_1(object sender, DockWindowEventArgs e)

{

try

{

e.DockWindow.Text = strCaption;

FillPrimitive fill = (FillPrimitive)((ToolTabStrip)e.DockWindow.DockTabStrip).CaptionElement.Children[0];

BorderPrimitive border = (BorderPrimitive)((ToolTabStrip)e.DockWindow.DockTabStrip).CaptionElement.Children[1];

fill.AutoSize = false;

fill.Size = new Size(e.DockWindow.Width, 35);

border.Shape = this.toproundedshape;

}

[Solved] Exception- AvlEnumerator:version mismatch

Hello,

I have recently upgraded to "RadControls for WinForms Q2 2010 SP2" and since then, occasionally, I'm getting this exception:

AvlEnumerator:version mismatch

The relevant call stack is:

at Telerik.Collections.Generic.AvlTree`1.Enumerator.CheckVersion()
at Telerik.Collections.Generic.AvlTree`1.Enumerator.MoveNext()

What can be the problem? I couldn’t find documentation for it.

Thanks,

[Solved] Hierarchy Template Problem

I've followed this tutorial for binding hierarchy data:

http://www.telerik.com/help/winforms/gridview-hierarchical-grid-tutorial-binding-to-hierarchical-data.html

The data is displaying properly, and the Parent level template works as it should. However, the child level template is not working at all. Whether I use the grid property builder or the template collections interface, I can not customize which columns are visible or change header names etc. It always shows every single column from the table adapter. I need to be able to use foreign keys which are invisible, not to mention renaming headers or resizing columns.

Thanks for the help.

Multiple Page Heights

Can the PageView control be programmed to support multiple page heights. I've got a couple of pages that will be fixed content, but then several that will have grids, so their heights should be resizable. Is this possible? If so, please point to examples.
Thanks!
