You want to bold a specific word in a sentence, if I understand you correctly, and not the whole sentence? The only way to bold a word inside a sentence, is to use the Rich Text control, which you can compare to an editbox functionally. I don't think you can use it inside a grid, but I may be wrong.
If you want to bold the whole text in a column, you may use the column's DynamicFontBold I guess, but I have never used it myself.
