ASPX

<dx:ASPxGridView ID="ASPxGridView1" runat="server" ...>
    ...
    <SettingsBehavior AllowDragDrop="false" />
    <Columns>        
        <dx:GridViewDataTextColumn FieldName="QuantityPerUnit" VisibleIndex="1">
            <Settings AllowDragDrop="True" />
        </dx:GridViewDataTextColumn>
        ...
    </Columns>
</dx:ASPxGridView>

Web Forms (in code):

C#

ASPxGridView grid1 = new ASPxGridView();
grid1.ID = "grid1";
Page.Form.Controls.Add(grid1);
...
grid1.SettingsBehavior.AllowDragDrop = DevExpress.Utils.DefaultBoolean.False;

GridViewDataTextColumn productColumn = new GridViewDataTextColumn();
productColumn.FieldName = "QuantityPerUnit";
productColumn.Settings.AllowDragDrop = DevExpress.Utils.DefaultBoolean.True;

MVC:

C#

@Html.DevExpress().GridView(settings => {
    settings.Name = "grid";
    settings.SettingsBehavior.AllowDragDrop = DevExpress.Utils.DefaultBoolean.False;
    GridViewDataTextColumn productColumn = new GridViewDataTextColumn();
    productColumn.FieldName = "QuantityPerUnit";
    productColumn.Settings.AllowDragDrop = DevExpress.Utils.DefaultBoolean.True;
    ...
