I'm trying to present a boolean column from a MySql table graphically with a GridImageColumn. I added a the GridImageColumn (myauth) and set it to emulate the boolean column (authorized). (myauth) GroupByExpression="Group By authorized" and SortExpression="authorized".
This works well, I can click on the (myauth) column header to change the sorting of the column, and I can drag the (myauth) column header to the group panel and group records. If however I try to click the sort icon on the (myauth) button added to the group panel, then the button is reduced to just a few pixels, and I loose the ability to group, ungroup, or sort by that column or any others on the grid.

Hello Raymond,
I am afraid that I am unable to replicate such behavior. Could you please prepare runnable sample that illustrates the behavior and send it to us via formal support ticket? Thus we'll be able to assist you further.

This was the entirety of the code for the project, there was no server side code.
I cant post formal ticket, wont be current till next calendar year (long story), and can't provide running sample (security issue). I will however try to replicate with a different database and without using the Devart / MySql to rule them out. Thank you though.

Well first, thank you for the continued support. Secondly, thanks of the idea, I was planning on a simple database and it hadn't occurred to me to just create the data dynamically.
This has turned into a bit of a head-scratcher. I couldn't get your sample to build without running into 'The name RadGrid1 does not exist in the current context'. My C# skills aren't that polished and I'm pretty sure I did everything right, but I can attribute that problem to my own error.
I took your code and the aspx table definition and started a new Delphi Prism project which compiled and ran, but with some odd results.
Under Firefox
I can drag the column headers, but not place them on the group panel, the cursor remains as a circle with a line through it.
Under IE
I can not drag the column headers at all. IE also reports page errors (firefox may just be ignoring them)
If I go to the RadGrid's task menu and select 'Replace ScriptManager with RadScriptManager it compiles and runs under both FireFox and IE, allowing me to group by the myauth column, but the initial problem still exists

project with radscriptmanager : http://steeltoad.com/groupsort/with_radscriptmanager.zip
Again, thank you for the help.

YES, that seems to be it. Using the DataAlternateTextField instead of GroupByExpression seems to be what was needed. I added to the code, setting the image based on the authorization column in the ItemDataBound event, and the Grouping/Sorting works exactly as it should. Thank you again.
