How to Implement Hierarchy Grid using NeedDataSource

Hi,
I have 3 asp.net grid nesting. For example Top grid contains List of Categories, then innergrid1 contains list of Questions, then innergrid2 contains Question's Answer options.

What will be the best possible approach to do this?

When i just changed the asp grid with rad grid it slowed down page performance drastically. So i thought of implement hierarchy grid.
If this can be done using hierarchy grid then

How to Implement Hierarchy Grid using NeedDataSource?

Because sqldatasource is not used in our application.

possible to have both 3.5 and 4.0 in the toolbox?

So I have projects that are still being built on 3.5. But I want to start my new projects on 4.0. I went and created a new tab called RadControls4.0, browsed to the latest 2011.xx 4.0 dll and added it. Much to my disappointment it nuked all my Radcontrol3.5 items and the tab as well! Is it not possible to have both dlls in the toolbox in their own respective tabs?

GridDropDownListColumnEditor width

How do you set the width of a GridDropDownListColumnEditor on the server.

I have a method tied to OnCreateColumnEditor called "CreateEditor". It looks something like this

protected void CreateEditor(object sender, GridCreateColumnEditorEventArgs e)
{
GridDropDownListColumnEditor operatorEditor = e.ColumnEditor as GridDropDownListColumnEditor;
operatorEditor.ComboBoxControl.DropDownWidth = Unit.Pixel(50);
}

But the width never gets changed to 50px. It is a lot longer than that.

Apply CSS Class not working for images in IE9

If I specify a content area CSS class like this:

img.right-align

{

float: right;

margin: 5px 0 5px 5px;

}

then the ApplyCssClass toolbar will not apply it to the selected image in IE9. It works in Firefox.
In IE9 if I right-click on the image and choose properties, then I can apply the class.
However, Clear Class from the ApplyCssClass toolbar also only works in Firefox, and Clear Class from the properties window doesn't work in Firefox or IE9.

Disable post back when Autogenerated Edit button is clicked

Hi,

We have the following grid. Earlier when we used to click the autogenerated edit button, postback never used to happen. Now after somebody changed something, a postback is firing on edit button click which is not desired. We need to fire the updatecommand when the update button is clicked inside the edit form.

TreeView not rendering when context menu on same page

I have a TreeView control that renders correctly on my page (style gets applied). However, if I add a context menu to the page my style does not get loaded for the TreeView (it renders as bullet points).

Note: My context menu is for a different control on the page, not for the treeview.

I am assuming this has something to do with both controls using the <ul> element, how can I have both controls on the same page without this rendering issue?
