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;
