$find is unefined

I am trying to open a radwindow that is scripted in a top base page that has frames. I have a method on my base page called "ShowRadWindow". This method does a $find for the radwindow, then a seturl and show. Withing a frame page from the page, I call a method when a submit button on the page is clicked. It in turn calls ShowRadWindow. For some reason I am getting an error back saying that $find is undefined. How do I get that symbol from my frame page calling the parent.ShowRadWindow?

Column visibility in Hierarchy grid

Hi,
     I have to make a column invisible in a childgrid based on some conditions. Some thing like i have 3 columns and i have to show/hide these columns depending on some conditions. I tried to do it under DetailTableDataBind method, but in vain. My code is something like this:
DetailTableDataBind Method
begin
                If<Condition is true>
                 Hide these columns i.e.    e.DetailTableView.GetColumnSafe("ColumnName").visible=false;
               else
                Hide these columns
end.
By default all these columns are visible and AutogenerateColumns is set to false. I also took a variable and assigned a value in DetailTableDataBind event and used it under columnCreating, columnCreated events just to make sure that it does n't work. Can somebody help me in this issue.

Using browser's default style

My company just recently bought the teleriks control. I've been asked to change the style of the telerik's control to match our current style. We currently are not planning on replacing everything with the telerik's control. We have the ajax controls by the way. For the combo box, we do not use any kind of style, it currently use the default style that is offered by the browser or the OS. Is there anyway that I can turn the telerik's control skinning off so that it will use the default style that's offered by the browser so that the style of the old control will match the new one?

Thanks in advance.

Disable hover icon when Treeview is hovered

I am using a RadTreeview (ASP.NET Ajax version 2011.2.915.40) and I want the hyperlink 'hand' icon to not show when a node is hovered. I have successfuly implemented the style below:

.RadTreeView .rtHover .rtIn
        {
           background: none !important;
           border: none !important;
           padding: 4px 3px 3px !important;
           background-image: none !important;
        }

and this removes the highlight color when nodes are hovered.

I really need to find a way to allow the mousepointer to remain the default arrow when the control is hovered. I've noticed that the hand appears as soon as the mouse enters the TreeView control - even if a node is not being hovered.

How can I do this?

$telerik.$

In the code samples here:
http://www.telerik.com/support/kb/aspnet-ajax/scheduler/setting-special-days-or-time-slots-in-radscheduler.aspx
There is a call to $telerik.$(...)

It doesn't seem to be documented in the telerik class:
http://www.telerik.com/help/aspnet-ajax/telerik-static-client-library.html

Any insight?

[Solved] Assign unbound grid edit form textbox values

Hi,

I have a grid that consists of customer details which is populated from a database. One of the customer attributes is the Sort Code. I would like to be able to bind the values of this to the appropriate textboxes when editing a customer. In the database, this item is stored as a single 6 digit code, however, as is convention, the user enters the code in 3, 2 digit text boxes. Usually one uses the

Text='<%# Bind("blah") %>'

technique, however in this instance this is not possible as there are 3 separate textboxes. When would be the best point to assign the values through codebehind? At the editcommand event (though afaik edit form items are not accessible from here)? Any help would be greatly appreciated.

Cheers,
Christian
