When the CellTemplate of a given column is predefined, it is expected the highlighting of the search mechanism not to be working. The control is simply not aware what element is defined within the DataTemplate. Thus, it cannot highlight its content. A possible approach that you can adopt would be to define a custom TextBox element that supports highlighting. Such solution is demonstrated in the Highlighting inline Search for RadGridView
blog post. A similar approach but through the usage of a custom column can be observed in the Custom Highlight Column
This, however, is already discussed in the Highlghting doesn't work while searching/filtering
forum thread you opened regarding a similar inquiry. May I kindly ask you to clarify whether you are experiencing any specific obstacles to implementing one of the suggested solutions?
