Self Referencing hierarchy RadGrid - JS error

Hi There,

I have implemented a self referencing radGrid as provided in the documentation, only change made was using an image button instead of button as in the example
http://www.telerik.com/help/aspnet-ajax/grid-self-referencing-hierarchy.html

It worked fine with .net framework 2.0, we recently migrated to 4.0 and now its showing up a javascript error on click of the image button. Attaching the javascript error image.

How can I resolve this?

Thanks,
Vinay

CreateColumnEditor is fired for an Insert or an Edit?

Hi!

I'm trying to do something.

I need to have different inline editor base on the type of edition...

It can be an insert or an edit.

I want to be able to have different ColumnEditor defined in the event CreateColumnEditor of the RadGrid depending on if it's edit mode or insert mode.

The event gives object but I have no clue if it is an insert or an edit.

Is there a way to identify if the event was fired for an insert or an edit?

Thanks!

protected void RadGrid_OnCreateColumnEditor(object sender, Telerik.Web.UI.GridCreateColumnEditorEventArgs e)

{

if (e.Column is GridBoundColumn)

{

if ((e.Column as GridBoundColumn).DataField == "UserValue")

{

e.ColumnEditor = new NumericColumnEditor("UserValue");

}

else if ((e.Column as GridBoundColumn).DataField == "UserId")

{

e.ColumnEditor = new LabelColumnEditor("UserId");

}

else if ((e.Column as GridBoundColumn).DataField == "UserName")

{

e.ColumnEditor = new LabelColumnEditor("UserName");

}

Very slow RadTreeView

Hi there!
I've a problem with RadTreeView control. I'd like to create a (rather) big tree (6 levels, with 300 hundred leaves). Every node need to have a checkbox; checkboxes need to be tri-state. The thing is that I need to read the selection (of nodes) from the database, display whole tree and then the selection of leaves (and according parent nodes). Only selected intermediate nodes will have their subtree expanded. So the problem is that while I render the whole tree, the page is starting to run veeery slow (I've checked in FireBug - whole page has 211 kB!!!). I thought that LoadOnDemand would solve my problems, but it's not that easy because sometimes I'll need to have whole tree expanded (every leaf node selected). Any suggestions?
