 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. Everything works fine except Extract values function does not return any values. Please follow below code example for better understanding.

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

Hi All!

I have a radgrid that uses a SQL database for its datasource.  The fields are of type "date" so there are no times in the database fields.  However, my radgrid adds 12:00:00 AM to all of its times.  I have attempted DateFormatString = "{0:MM/dd/yy}" or "{0,d}" but neither seem to work.  Any thoughts?

Thanks,
Mark

Hi,

I have an issue refreshing a radscheduler using Telerik ajax
My page contains a RadTabStrip, one of which is containing a RadScheduler.
When I update one of my page element using Telerik ajax, I would like my scheduler to be regreshed but despite my Appointments list is being refreshed server side, the scheduler is not refreshed clietn side whereas another ajaxified field is.
I have readed many threads on the forum but i still did not find a solution

Below are some extract of the code:

.aspx


.aspx.cs


When debugging step by step, I update appointments list but it never appears correctly on client side
Moreover, if my appointment list is empty at first load, depending on my browser, the radscheduler is sometimes shrinked with a javascript error in the axd file..

If any one has a good idea....it would be greatly appreciated

Regards.
