I am using a RadGrid that contains 5 columns. The first 3 columns in the grid are a GridBoundColumn, the fourth column is a GridDropDownColumn, and the fifth column is a GridEditCommandColumn. At runtime, when the grid is populated, the fourth column (the GridDropDownColumn) displays instead of the expected data. If I change the fourth column from a GridDropDownColumn to a GridBoundColumn, the grid displays the proper data. This problem only occurs when I use the GridDropDownColumn. Is there something magical about the Grid*Bound*Column? IOWs, am I having this problem b/c the GridDropDownColumn is not a *bound* column?
I have found and reviewed the "forum log" GridDropdownColumn in RadGrid not working, which indicates that the solution to this problem is to install the latest version of the Telerick Ajax controls, but the version that I have installed (2011.2.712.40) is already higher than what is indicated in the "forum log".
I want to use the GridDropDownColumn so that when a user clicks the grid's edit button (GridEditCommandColumn), I can control which values they are allowed to enter via a dropdown list.
So the grid displays in the GridDropDownColumn when it is populated. But when I click the edit button on the grid, the GridDropDownColumn then displays valid values, instead of
Actually, to state what I just said more accurately, valid values only display in the GridDropDownColumn for that row on which I clicked the edit button and for every row that appears below the row that I am editing. But for the rows that appear above the one that I am editing, they still display in the GridDropDownColumn.
How do I resolve this problem?

Let me provide a little more detail so that hopefully someone will respond to this post.
If I assign a ListDataMember to my GridDropDownColumn, then I no longer have the issue of the HTML tag appearing in my RadGrid. But by including ListDataMember, it limits (or filters) the values that appear in the GridDropDownColumn.
To illustrate what I mean, the GridDropDownColumn is based on a DataTable, and the table contains a row for #1, and a row for #2, and a row for #3, ... all the way up to a row for #16. My objective is to always have my GridDropDownColumn show every value in the lookup table (values 1 thru 16).
The RadGrid contains a list of students, where column 1 is the student's last name, and column 2 is a value between 1 and 16. If I apply a filter to the RadGrid so that it only displays students whose last name begins with D, only 3 students appear in the grid; Doe, Davis, and Dolittle. Doe has a value of 2, Davis has a value of 6, and Dolittle has a value of 10. If ListDataMember has been specified and I attempt to edit any one of the 3 students, the GridDropDownColumn only displays values 2, 6, and 10; it has been affected by the RadGrid filter.
Since I want the GridDropDownColumn to always display values 1 - 16, I remove ListDataMember, but that is when my RadGrid begins to display the HTML tag as described in my initial post.
This is the problem that I am trying to resolve and I am sure that someone else has run into this issue before.
Thanks
The issue is already fixed. You could resolve your issue by downloading later than 2011.2.712.40 version of the controls. In the 2011 Q2 SP1 release notes is stated that the issue is already fixed.
