can we hide selected data in the datagridview c# code example

Example 1: c# datagridview hide column

this.dataGridView1.Columns["ID"].Visible = false;

Example 2: c# datagridview hide row selector

//Set the RowHeadersVisible to False in the GridView (it's a property)
//Or By Code:
DatagridView.RowHeadersVisible = false;
