求助：关于ASPxgridview

ASPxGridView中 GridViewDataComboBoxColumn 怎么实现下拉

解决方案 »

  1.   

    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？

    你的KeyID有两个？去掉一个试试
      

  4.   

     <dx:ASPxComboBox ID="ddlCJ" ClientInstanceName="ddlCJ" runat="server" ValueType="System.String"
                            Width="120px" TextField="JGMC" ValueField="JGBM">
                            <ClientSideEvents SelectedIndexChanged="function(s, e) {ddlQJZC.PerformCallback(s.GetValue().toString());}" />
                        </dx:ASPxComboBox>

    下拉列也要设置一个DataSource吧
