下拉列也要设置一个DataSource吧

前台：<dxwgv:ASPxGridView ID="grid" ClientInstanceName="grid" KeyFieldName="keyid" OnCellEditorInitialize="grid_CellEditor"
runat="server" DataSourceID="ObjectDataSource1" AutoGenerateColumns="False">
<Columns>
<dxwgv:GridViewDataTextColumn FieldName="keyid" Visible="false">
</dxwgv:GridViewDataTextColumn>
<dxwgv:GridViewDataTextColumn FieldName="name" Visible="true" Caption="省份" VisibleIndex="1">
</dxwgv:GridViewDataTextColumn>
<dxwgv:GridViewDataComboBoxColumn Caption="城市" FieldName="keyid" VisibleIndex="2">
<PropertiesComboBox EnableIncrementalFiltering="true" EnableSynchronization="False" DropDownStyle="DropDown">
</PropertiesComboBox>
</dxwgv:GridViewDataComboBoxColumn>
<dxwgv:GridViewDataTextColumn FieldName="description" Caption="描述" Visible="true" VisibleIndex="3">
</dxwgv:GridViewDataTextColumn>
</Columns>
</dxwgv:ASPxGridView>
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
SelectMethod="Selectrole" TypeName="Traffic.Business.BusinessAspxGridView"></asp:ObjectDataSource>
后台：

string val = (string)grid.GetRowValuesByKeyValue(e.KeyValue, "keyid");
ASPxComboBox com = e.Editor as ASPxComboBox;
if (string.IsNullOrEmpty(val)) return;
BusinessAspxGridView bus = new BusinessAspxGridView();
List<string> editor = bus.Selectruser(val);
foreach (string s in editor)
{
com.Items.Add(s);
}
为什么下拉项没有出来呢？
