I am using a data table and a datagridview. I am creating two columns in data grid view : 1)DataGridViewComboBoxColumn 2)DataGridViewTextBoxColumn. The items of datagridviewcombo are the list of all items in data table column 1. I want that the data type of the DataGridViewTextBoxColumn should be the same as the data type of the item selected from the datagridviewcombo at runtime. How can I do that.Also I want that each cell in column of datatable should be of variable data type. Pls help. thnx.
