How to Hide Column in DataTable or GridView

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.
