If you want to hide column in datatable dynamically, here is
the simple code for that.
You need to add this code in load event or anywhere else.
// Create new Datatable
DataTable dtStudent = new
DataTable("Student");
// Add Columns
DataColumn DColStdID = new
DataColumn("Stud_ID",
System.Type.GetType("System.Int32"));
// hide column in datatable. this will not display in
DataGridView
DColStdID.ColumnMapping = MappingType.Hidden;
dtStudent.Columns.Add(DColStdID);
DataColumn DColStdName = new
DataColumn("Name",
System.Type.GetType("System.String"));
dtStudent.Columns.Add(DColStdName);
DataColumn DColStdClass = new
DataColumn("Class",
System.Type.GetType("System.String"));
dtStudent.Columns.Add(DColStdClass);
//Adding data
dtStudent.Rows.Add("100", "Wasi", "2nd");
dtStudent.Rows.Add("101", "Shref", "3rd");
dataGridView1.DataSource = dtStudent;
Now add the datagridview on form. And run the code.
