DataGridTableStyle.ReadOnly Property

Gets or sets a value indicating whether columns 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 columns cannot be edited; otherwise, false.

You can also specify whether individual columns within the table are editable by setting the DataGridColumnStyle class's DataGridColumnStyle.ReadOnly property to an appropriate value, true or false.

Alternatively, to ensure that the data is not edited, you can set the DataColumn class's ReadOnly property to true.

The following code example returns the ReadOnly property for each DataGridTableStyle in a GridTableStylesCollection.

private void PrintReadOnlyValues()
    foreach(DataGridTableStyle tableStyle in dataGrid1.TableStyles)
