DataGridViewBand.ReadOnly Property

  • Reference

Definition

Namespace:
System.Windows.Forms
Assembly:
System.Windows.Forms.dll

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

public:
 virtual property bool ReadOnly { bool get(); void set(bool value); };
public virtual bool ReadOnly { get; set; }
member this.ReadOnly : bool with get, set
Public Overridable Property ReadOnly As Boolean

Property Value

Boolean

true if the user cannot edit the band's cells; otherwise, false. The default is false.

Exceptions

InvalidOperationException

When setting this property, this DataGridViewBand instance is a shared DataGridViewRow.

Examples

The following code example demonstrates how to use the ReadOnly property to disable editing for an entire DataGridView. This code example is part of a larger example provided for the DataGridViewBand class.

// Make the entire DataGridView read only.
void Button8_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
   System::Collections::IEnumerator^ myEnum = dataGridView->Columns->GetEnumerator();
   while ( myEnum->MoveNext() )
   {
      DataGridViewBand^ band = safe_cast<DataGridViewBand^>(myEnum->Current);
      band->ReadOnly = true;
   }
}

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

' Make the entire DataGridView read only.
Private Sub Button8_Click(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles Button8.Click

    For Each band As DataGridViewBand In dataGridView.Columns
        band.ReadOnly = True
    Next
End Sub

Remarks

The ReadOnly property affects the DataGridViewCell.ReadOnly property of each cell in the band. For example, if the ReadOnly property of a DataGridViewRow changes, then the DataGridViewCell.ReadOnly property of all cells in the row will change.
