CheckChildNodes and LoadOnDemand?

Suppose you have a treeview with CheckBoxes and CheckChildNodes set, and you are using LoadOnDemand.

The user clicks on a checkbox for a parent node whose children have not yet been loaded.

What happens? Are the child nodes loaded? If not loaded, is the altered checked state of the child nodes nevertheless transmitted to the server upon postback?

Giant Exception when adding SPRadListView to site

Hello,

I have a Document Center Site Collection (home site) onto which I wanted to place this web part. I tried several times to get it working, installing and uninstalling the web part a few different times. Now, I think everything is installed correctly but when I add the web part to the page, I get the error below. Is this because I installed and uninstalled the solution so many times? I made sure the web part's feature was enabled on the site collection, and everything. Had to use Web Part Maintenance page to remove the part so that I could view the page again.

Thanks,
- Matt

RadEditor ToolbarProviderID while using RadPageView

We are trying to use the ToolbarProviderID functionality with multiple RadEditor controls. The RadEditor controls are being instantiated at RunTime. When the first RadEditor control is being created, we store the ID of that Editor to be used as the ToolbarProviderID for later Editors.

When we run, the Toolbar on the first RadPageView page where the first Editor is drawn renders as it should. When I switch to a Tab that contains an additional Editor, we encounter a Javascript error.

My question: how do we use the ToolbarProviderID when the ID of the control will not be visible because of the RadPageView hiding the control?

[Comments in RadEditor] Changing RadEditUser/Author attribute

Hi,

I am now integrating RadEditor into my collaborative appliaction. I found the feature "commenting in RadEditor" interesting as users are able to make comments on the contents. However, I just wonder how to change the RadEditorUser/Author attribute because everytime a user makes a comment, Radeditor would set the author as "RadEditorUser". This causes confusion as users cannot distingish their comments with those made by others.

Thanks
Nelson
