You can set the type of data the column will hold as the following code snippet illustrates:

var columnSpec = new DataColumn();
columnSpec.DataType = 
// Other initialisation
dataTable.Columns.Add(columnSpec);

dataGridView.DataSource = dataTable;

If you are working directly on the DataGridView then the DataGridViewColumn class has the following property:

ValueType - Gets or sets the data type of the values in the column's cells.

If you create your columns using this class rather than the more specialised classes DataGridViewCheckBoxColumn etc. this might do want you want.
