GridView with multiple DataSources

I have a grid view that will display columns from multiple data sources (3). The data sources are stored procedures that contain开发者_JAVA百科s a variety of columns not identical, How can i select the columns from these datasources and bind them to the Grid programtically (from code behind)???

Thanks

Create three separate datasets (one for each datasource that you'll be retreiving data from) and then merge them in code before binding.
