How to: Remove Autogenerated Columns from a Windows Forms DataGridView Control

When your DataGridView control is set to autogenerate its columns based on data from its data source, you can selectively omit certain columns. You can do this by calling the Remove method on the Columns collection. Alternatively, you can hide columns from view by setting the Visible property to false. This technique is useful when you want to display the hidden columns in certain conditions, or when you need to access the data in the columns without displaying it.

To remove autogenerated columns

  • Call the Remove method on the Columns collection.

    dataGridView1.AutoGenerateColumns = true;
    dataGridView1.DataSource = customersDataSet;
    dataGridView1.Columns.Remove("Fax");
    

To hide autogenerated columns

  • Set the column's Visible property to false.

    dataGridView1.Columns["CustomerID"].Visible = false;
    

private void BindDataAndInitializeColumns()
{
    dataGridView1.AutoGenerateColumns = true;
    dataGridView1.DataSource = customersDataSet;
    dataGridView1.Columns.Remove("Fax");
    dataGridView1.Columns["CustomerID"].Visible = false;
}

This example requires:

  • A DataGridView control named dataGridView1 bound to a table that contains Fax and CustomerID columns, such as the Customers table in the Northwind sample database.

  • References to the System and System.Windows.Forms assemblies.
