DataGridColumnStyle.ReadOnly Property

Gets or sets a value indicating whether the data in the column can be edited.

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

public virtual bool ReadOnly { get; set; }

Property Value

Type: System.Boolean
true, if the data cannot be edited; otherwise, false.

Make a column read-only if it contains a primary key or if its value is generated automatically (as when the DataColumn object's AutoIncrement property is set to true).

Similar read-only properties exist on other classes, each allowing more control over the access to data. For example, the System.Windows.Forms.DataGrid control can be set to read-only mode by using its ReadOnly property; the DataGridTableStyle also has a ReadOnly property, and the DataColumn class has a ReadOnly property for restricting data updates.

The following code example sets the DataGridColumnStyle object's ReadOnly property to the same value as the DataColumn object's ReadOnly property.

private void SetReadOnly()
{
    DataColumnCollection myDataColumns;
    // Get the columns for a table bound to a DataGrid.
    myDataColumns = dataSet1.Tables["Suppliers"].Columns;
    foreach(DataColumn dataColumn in myDataColumns)
    {
        dataGrid1.TableStyles[0].GridColumnStyles[dataColumn.ColumnName].ReadOnly = dataColumn.ReadOnly;
    }
}
