Hi,

I created an orgchart based on the rendered fields demo @ http://demos.telerik.com/aspnet-ajax/orgchart/examples/renderedfields/defaultcs.aspx.

How can i change the style of the node based on a rendered filed value? For example an employee node  must have green background while a non employee must have a blue background

Hello,

I've been searching for a solution to my problem, but it appears that my issue is unique.

I have had a working web site using RadGrid grid controls for several years until yesterday.  Orginally, this was developed in a 2008 version of Telerik Radcontrols, but I have recently updated it to Version=2013.3.1015.35 to run on a soon-to-be sunset-ed web server.  This upgrade occurred in October or so and things have been fine until a few days ago.

I had to make a change some C# logic that had been discovered to be wrong.  Once the code was tested and approved, the changes were pushed to the production server.  A few days later, it was discovered that there was a problem adding records to the back-end database and having the grid redraw itself.  In fact, the error seems to be coming from the client since it is bypassing any server side error handling that I've built.

The funny twist on this is that there is nothing really happening to the grid.  The users are selecting data from ASP controls that will then be posted back to the database and the grid will be redrawn after the users is done selecting and typing what they need.  They don't get that far.  Before there can be any finalization, the ASP form throws and unhandled exception and references a GridTemplateColumn as the culprit.(See attached).  All server-side code executes without a hitch, but as soon as the grid is being drawn, this error comes up.

Here is the RadGrid ASP.NET code for the GridTemplateColumn:
 I am not sure why this is happening and I am out of ideas.  Any help would be greatly appreciated.

hey everyone i want to reduce space between columns. how to do this. i am using itemstyle-width but its increase the space..

 HI,
I have created one form with dynamic telerik RadGRID with template columns as shown in the exmple URL: http://www.telerik.com/help/aspnet-ajax/grid-custom-edit-forms.html.

If I include Protected WithEvents RadGrid1 As RadGrid I get 'RadGrid1' is already declared as 'Protected WithEvents RadGrid1 As Telerik.Web.UI.RadGrid' in this class. If I remove that line "RadGrid1.DataSource = thedata" I get "unknown entity" for RadGrid1. What is wrong - thanks
