Hello Admin,
I am a beginner in the web development and need to use telerik radscheduler in our website. I used the radscheduler with sqldatasource control. have been suggested not to use it. So, I want to use custom dataprovider but don't want to customize the advance form. Is it possible?  if yes then Could you please provide the demo project with only custom dataprovider  not the custom advance form? I have gone through some demos on custom dataprovider provided by you on some forums but all have customized advanceform. I also tried to use only custom dataprovider but failed. Also I need to add the Students And Lesson resources at runtime.
My Appointments table contains following fields:
AppointmentId
Subject
Start
[End]
LessonTypeId
InstructorId
CustomerId
RecurrenceRule
RecurenceParentId
Description
IsInactive
IsDelivered
IsEdited
IsDeleted
FlightHours
GroundHours
Comments
------------------------
LessonTypeId , InstructorId, CustomerId are the resources.

Help me.
Please reply as soon as possible.

Thanks in advance,
Roshani

i am changing column names for grid in code behind

 

 

if (fr == 1)

 

 

{

 

 

 

if (e.Item is GridHeaderItem)

 

 

{

 

 

 

GridHeaderItem headerItem = (GridHeaderItem)e.Item;

 

 

headerItem.Cells[2].Text =

 

"New Name";
}
}
It works fine.But after it i cant sortthis column by clicking on column name?

Hi ,

any suggestions on this?

Thanks

Hi,
We bought Telerik ASP.NET controls, and I'm now trying to use a RadTextBox in a stretchable layout. I set RadTextBox's Width to but in runtime I see that width is dynamically maintained by Telerik's scripts directly on <input> using "style" attribute and is always set to exact pixel value. And Telerik's scripts make the width visually correct (logically 100% in a layout) only on initial page load. If I resize browser window after page is loaded, width of RadTextBox is not updated and ruins layout.

From forum posts I see that Width handling is a known problem here. But since we are bound by contract terms to deliver application by a fixed deadline, I need at least know when the bug will be fixed by Telerik and released to customers.

Can you give us estimates on when the Width fix will be released?

Hello,

When I try to position the RadButton with to the right with:

 

.RadButton_Right,

  

.RadButton_Right .rbDecorated

  

{

  

position: absolute;

  

width: auto;

  

right: 0px; 

  

}

it doesn't seems working, but it work fines with RadTextBox or other Asp Button, Asp TextBox, I wonder what's the proper way to do it?
Because I want to have few buttons on the left, and a another Button on the right...
Thanks
