Property Value

Type	Default	Description
DefaultBoolean	Default	One of the DefaultBoolean enumeration values.

Available values:

Name	Description
True	true. DefaultBoolean.True has a constant value of 0, while the standard true value corresponds to a value of 1. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
False	false. DefaultBoolean.False has a constant value of 1, while the standard false value corresponds to a value of 0. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
Default	The default behavior determined by the control’s logic.

Remarks

If the AllowDragDrop property is set to Default, the column’s behavior is controlled by the ASPxGridViewBehaviorSettings.AllowDragDrop property.

Concept

• Bands

• Move Columns

Example

Declaratively:

ASPX

<dx:ASPxGridView ID="Grid" runat="server"... >
    <Columns>
        <dx:GridViewBandColumn AllowDragDrop="true" >
            <Columns>
                <dx:GridViewBandColumn AllowDragDrop="true" >
                    <Columns>
                        <dx:GridViewDataTextColumn FieldName="CompanyName" />
                        ...
                    </Columns>
                </dx:GridViewBandColumn>
            ...
            </Columns>
        </dx:GridViewBandColumn>
    </Columns>
</dx:ASPxGridView>

In code:

C#

ASPxGridView grid1 = new ASPxGridView();
grid1.ID = "grid1";
Page.Form.Controls.Add(grid1);
...
GridViewBandColumn band1 = new GridViewBandColumn();
band1.AllowDragDrop = DevExpress.Utils.DefaultBoolean.True;

GridViewBandColumn band2 = new GridViewBandColumn();
band2.AllowDragDrop = DevExpress.Utils.DefaultBoolean.True;

GridViewDataTextColumn textcol = new GridViewDataTextColumn();
textcol.FieldName = "CompanyName";

band1.Columns.Add(band2);
band2.Columns.Add(textcol);
