Hi,

I am running into the dreaded "A script is causing IE to run slowly" problem with expand and collapse all.  There are about 4000 items in the tree, but only about 50 or so are not leaf items.

Expand/Collapse all sample
http://www.telerik.com/help/aspnet-ajax/tree_clientexpandingcollapsing.html

I have tried both of these with no luck
http://www.telerik.com/help/aspnet-ajax/troubleshooting-treeview-script-causes-ie-run-slowly.html

Any other suggestions for getting this to not time out?  I have the same tree using Dyanmic Drive Simple Tree menu (http://www.dynamicdrive.com/dynamicindex1/navigate1.htm) and it is able to expand and collapse all just fine.

TIA

Hello Admin,

                 I'm calling a webservice method from radcombobox.
Due to slow internet speed, the Getmethod is failed to access the method.

How can I rectify this problem.

Please help me.

With regards,
Arul kumar

    

Hi i am using rad scheduler in my business application.

My requirement is to modfiy the template which appears on pop up after clicking New appointment. After going thrigh some articles i came to know that i can write the contents in <AdvancedInsertTemplate>. For this i refered sample code on your site. I created a user control and then inherited the same in  AdvancedInsertTemplate as per the example given. Everything works properly except when i click the New appointment button a window pops open in scheduler rad pane and calendar rad pane remains as it is. I want to open the popup on entire page and not in rad pane.

I searched throufh several forums and kb's to find solution but couldn't quite get the one. Any help in this regards will be appreciable. 

If I have:

var radGrid = (RadGrid)source;

 

 

var selectedValue = radGrid.SelectedValue.ToString();

 

 

(it happens to be an int)

And if I then throw that selectedValue to another grid on another page view a querystring redirect, what's the most efficient way to select the relevant grid row (supposing that row exists with the equivalent value) given that SelectedValue doesn't have a Set accessor?

Thanks,
Richard

 

Currently, I'm changing the color of different calendars using something to the effect of:

e.Appointment.CssClass = <css color>

However, I would like to set this based on an ARGB color that I'm getting through the rad ColorPicker. How would I go about doing this?

 I am trying to add dynamic text boxes inside of a edit form popup from radgrid, in a manner where a user can hit "add new text box" button and another text box for data entry would appear. I Have found a sample of code that does this in VB I am looking for some guidance on how this can be accomplished in the edit form template  

Hi All,

I have a requirement of accessing the datasource of the RadGrid on the Client side , Since i do some on the fly calculations. I need to fetch those values to be saved in the database. It is very urgent.

(Note : I am using Q3 2008 Version of the telerik)

Thanks in Advance,

Hi EveryBody, 
                         I have a RadGrid with ten Template columns in that only one column is visible at a time.
                         I want find which column is visible in the grid in another User Defined Function(not in any grid events).
                         Any one please give an idea on this.

Thank You

Hi Everyone,

Is it possible to disable/enable command items of master table when it is expanded? If yes, How?

Attached is the UI for reference.

Thanks!
