I have a stack column in RadGrid (shown in below image) and I want to apply sorting on the both fields of that column. For the sorting these columns I had applied my own logic and I could sort the columns but I am not able to apply color on column header and the ascending descending image which comes when we use default sorting of RadGrid.
Please tell me how to apply color and image to that column while sorting and when we sort with this stack column then the column, which we had sorted previously should get the default column header style.
Or Is there any alternative to sort the stack columns?
Please reply ASAP.
