Hello
Another question from me a beginner.

It is easy to load raw DataSet to DataGrid.
What if I want to add html tags and styles tags to my DataSet before loading in DataGrid?

Is there an easier way then take DataSet1 and convert to string then add tags. Then create new DataSet2, convert string to DataRow (if this is possible - by add to collections of DataSet??) and databind DataSet2 to DataGrid.

Any simplier solution to this?

Your dataset should contain data not formatting (unless of course your data is formatting). What do you wish to achieve that requires you to modify the data? Are you just trying to establish a display of the data in a certain style? The datagrid control supports loads of styles and settings to modify the appearance of the grid.
