I am attempting to create a web service using the signature found in your example:

[ScriptService]
public class WebServiceName : WebService
{
[WebMethod]
public RadComboBoxItemData[] WebServiceMethodName(object context)
{
// We cannot use a dictionary as a parameter, because it is only supported by script services.
// The context object should be cast to a dictionary at runtime.
IDictionary<string, object> contextDictionary = (IDictionary<string, object>) context;

//...
}
}

As I understand it, the web service must return a RadComboBoxItemData array. However, when creating a web service using the above signature, I get an error saying the RadComboBoxItemData implements IDictionary and therefore can not be serialized. I'm sure I'm doing something wrong - but can't figure it out. 

I even took your sample code and compiled and got the same error!

Hi,

I've been using hierarchical grids for years and also your window edit for grids (http://demos.telerik.com/aspnet-ajax/window/examples/demoemail/defaultcs.aspx) for years without any problems but when I try to use the window edit technique from your above demo on a hierarchical grid I get the following error when I try to expand a child table:

Error: Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.

Is it possible to do what I'm trying to do with the demo technique or do I have to do it differently?

Thanks,

Craig

Hi All,

OK I've now done a fair bit of stuff with batch editing but have only just tried to work on it with a combo box while doing the saving myself.

I want to send the values to the server for bulk processing after the user has finished admin.  To that end after each row change I am parsing all the rows and adding the changed value to a comma delimited hidden field.  I wish there was a way to access all the changes fror all rows on teh server but until that day I need to do this fairly awful work around.

The problem that I have is that text fields are fine BUT when I am trying to work out the selected value of a combo box I draw a blank.  Sample code below.


I have tried all kinds of things but just cannot access the ID field.  Accessing the selected text is easy but not the id..

Any suggestions?

Regards

Jon

I am new to using the RadComboBox and using it as a trial basis to see if it fits what we need.

I have RadComboBox set up to use checkboxes, have Check All enabled, and being databound to a dataset.

This is set in an ASP.Net page with VB.Net as the code-behind.

So I have a few questions.

Is there an easy way to programmatically check all items in the combobox after being databound without using a for loop?

What is an easy way to get all the items that have been check marked by the user?

Sincerely,
Keith Jackson

Hi,

I would like to disable or handle the JS error popups somehow on the scheduler specially working with the webservice binding approach. 
I am receiving such as; "clone error: No target element specified"

Yes, my scheduler may be missing some data, however, I cannot determine the causes right away.

thank you

I want to show the next available time slot to the user. I.e., If user enters start date time as 3-02-2015 :09:00:00 with the length of 30minutes, we have to find out the time slot available for the given date time with 30minutes length, if there is no time slot available at the given time we need to show the next available time slot it may be some other date or some other time but the next available time slot should be greater or equal to 30minutes length.

Is there a way to do this? 

Hi there
             As i needed the culture property for telerik controls I have just upgraded my telerik version(2008) to 2010.3.1317.35. Once the upgradation done everything works fine but all the controls especially telerik RadGrid showing some style issue.
For instance the pagination has gone vertical instead of horizontal, also there are some spacing issues.
I have searched the telerik forums & followed the procedures carefully while upgrading, like replacing the old DLLs with new ones &
adding the references wherever needed. I couldnt get an idea of where im going wrong or what i need to do. Please assist me in this regard & help us sort it out as we're nearing our deployment. For ur info i've attached the screen shot & the mark-up code for that

Dear Telerik Team,

I am using RadGrid and a few splitter tricks for display and editing of large amount of data. In Edit mode, when the user keeps tabbing, the SAVE goes out of focus. Now the user has to click the right end of scrollbar to make the the Save appear all over again.

I am looking out to see if I can freeze the column that shows Update/Cancel (similar to the examples/demo shared out in http://www.telerik.com/community/forums/aspnet-ajax/grid/how-to-freeze-columns-in-radgrid.aspx)

How to make the column that shows Update/Cancel as Frozen? 

Dear All,
             I am using Telerik controls with Licensed version to my company, but some issue is occurring in RadGrid while we are using .net v4.0,
but it is working Good in .Net v2.0 with VS 2005 and same Radgrid dll for this.

When i click the RadGrid for sorting or Paging or Expanding Grid column in my application below error is occurred.
My Application is .Net Framework v4.0.(VS 2010) 
RadGrid Version: 3.0.2.0 
IE: 9.0
Operating System: Windows 7

Kindly solve this issue,
 
Thanks in Advance
