DataGridViewColumn.ReadOnly Property

Gets or sets a value indicating whether the user can edit the column's cells.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public override bool ReadOnly { get; set; }

Property Value

Type: System.Boolean
true if the user cannot edit the column's cells; otherwise, false.

ExceptionCondition
InvalidOperationException

This property is set to false for a column that is bound to a read-only data source.

The ReadOnly property affects the DataGridViewCell.ReadOnly property of each cell in the column.

The following code example demonstrates how to use the DataGridViewBand.ReadOnly property, which is nearly identical to the ReadOnly property of the DataGridViewColumn class. This code example is part of a larger example provided for the DataGridViewBand class overview.

// Make the the entire DataGridView read only. 
private void Button8_Click(object sender, System.EventArgs e)
{
    foreach (DataGridViewBand band in dataGridView.Columns)
    {
        band.ReadOnly = true;
    }
}
