Examples

The following code example demonstrates using the RefreshPropertiesAttribute class to specify the refresh mode for a DataSource property. For a full code listing, see How to: Apply Attributes in Windows Forms Controls.

[Category("Data")]
[Description("Indicates the source of data for the control.")]
[RefreshProperties(RefreshProperties.Repaint)]
[AttributeProvider(typeof(IListSource))]
public object DataSource
{
    get
    {
        return this.dataGridView1.DataSource;
    }

    set
    {
        this.dataGridView1.DataSource = value;
    }
}
<Category("Data"), _
Description("Indicates the source of data for the control."), _
RefreshProperties(RefreshProperties.Repaint), _
AttributeProvider(GetType(IListSource))> _
Public Property DataSource() As Object
    Get
        Return Me.dataGridView1.DataSource
    End Get

    Set(ByVal value As Object)
        Me.dataGridView1.DataSource = value
    End Set
End Property
