Data grid is not populated with data from data table

Question

I have created a data grid view, i have also created a data table with values now i want to add the whole data table to data grid view.

So here is my code // dataGrid is creditMemoGrid

 

creditMemoGrid.Columns[0].Name = "No.";

creditMemoGrid.Columns[1].Name = "Memo #";

creditMemoGrid.Columns[2].Name = "Amount";

DataTable table = new DataTable();

table.Columns.Add("Dosage", typeof(int));

table.Columns.Add("Drug", typeof(string));

table.Columns.Add("Patient", typeof(string));

// Here we add five DataRows.

table.Rows.Add(25, "Indocin", "David");

table.Rows.Add(50, "Enebrel", "Sam");

table.Rows.Add(10, "Hydralazine", "Christoff");

table.Rows.Add(21, "Combivent", "Janet");

table.Rows.Add(100, "Dilantin", "Melanie");

creditMemoGrid.DataSource = table; // no data in data grid

 

If i do "creditMemoGrid.DataSource = table" i dont see data in data grid. what is the problem that i am facing ?

Can anybody help me?
