Hello, Leenah,

The provided brief information is not enough to get a complete understanding of the exact goal that you are trying to achieve. However, if you want to add specific columns in RadGridView, please refer to the following help article which is quite useful on this topic:

Note that RadGridView allows adding columns with unique names.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
