Is it possible to use the group by function in RadGrid also using the Skip() and Take() linq functions rather than pulling the entire table in every time?  We're currently using a grid that has 40000 rows (and up to 30 columns) and using the Group By functionality takes over 2 mins to complete, causing a timeout. 

Currently when I use GroupBy with Skip and Take, it just groups the entries in that particular view depending how the table is sorted (i.e. just those 50 rows) rather than the correct grouping as it would be over the full 40000 rows.  Is there any way to get this to work correctly?

Hi,

Can we customize the Progress Indicators which is shown when uploading the Files to the server? (Red, Green, Yellow one)

I want it to customize as shown in the attached image.

Thanks,

Two questions:

1. Is it possible to not require a click to use Batch Editing - e.g. Grid is always in edit mode? 
2. How do I insert an empty item into a GridDropDownColumn in batch mode? 

Thanks.​

Hi

I have a radgrid with insert/update/delete function available (NOT automatic but manual).  Behind my tool there is a user database with security settings.  I need to set the insert/update/delete function unavailable for the users that have no rights to do this and for the user who have right to do this the insert/update/delete function must be availabe.

My question is how do I make the functions unavailable? How can I do this in code behind?

Please advice.

Kind regards

Suzy

I've got a very simple page to try to start using the scheduler. At the moment all the page has on it is the scheduler.

I don't know javascript and have no script code. At the moment all I have done is create a blank form, added a scheduler control, added the radscriptmanager and radajaxmanager, in code behind loaded the datasource for the schedule and that's it.

When I run it the page is displayed and I can see, insert and edit appointments using the standard form. However, if I click options to view the advanced form I get an error:

Unhandled exception at line 23, column 5 in http://localhost:49335/ScriptResource.axd?d=nv7asgRUU0tRmHNR2D6t1FKDG35DvsT9LAUygLmmdVzKrxno8KQVmwLs8qIoJRFRSN2_iVk48PbTDpCzQFpmPsmuSwszBL8PM3oZkazX6hA33N42Fbe9eIkay7-ZsJoBG1bPh5lr6Jn8TgjwZbk5xA2&t=fffffffff11c85e00x800a1391 - JavaScript runtime error: 'Page_Validators' is undefined

The code highlighted is:

function ValidatorUpdateIsValid() {
Page_IsValid = AllValidatorsValid(Page_Validators);
}

In scriptresource.axd

I have a radgrid that inherits it hierarchy from a System.Data.DataSet. When I make a change I update the database from which the DataSet gets its data and rebuild the grid as this answer suggests. The first time the update always runs as expected and updates in the grid. After that after varying amount of changes( I can't seem to figure out exactly which one causes this) I get the following error:

JavaScript runtime error: Unable to get property 'get_element' of undefined or null reference

I hope you are able to help
