How to add empty group header item

I am using group by expressions to divide my grid into groups. I am using data that can exist in one of two groups, Group A and Group B for example. In some instances, data from one of the two groups is not present in the data source. I would still like to display a group header for the empty group and indicate that there are 0 (zero) records in the group. How do I go about adding a GroupHeaderItem to the Grid?

LoadRtfContent within Radeditor

I am trying to use radeditor to edit a file. The steps I need to go through are

- read the file (rtf or docx) from the web server and load it into the radeditor
- save the changed version back to the webserver (though upload)

I was reading the example that used the LoadRtfContent method but I dont see the same for the radeditor that I have placed on the form. Was this feature added in a specific version of Rad ?

Invalid date

I am typing in a date of '5/3/1958' and 05/03/1958' for a date of birth and am getting a yellow triangle (which signifies an invalid date format).

I have the following html:

<

telerik:RadDatePicker ID="terSubDOB" runat="server">

</DateInput>

</telerik:RadDatePicker>

What is wrong with my format?
