GridDropDownColumn with onneeddatasource

[Minh]

Hi,

i'm binding my radgrid1 to an onneeddatasource. All of the columns work fine except for the GridDropDownColumn. This column fail to populate with data in regular mode.

 

 

<telerik:GridDropDownColumn DataField="_UnloadTypeName"  

DataSourceID="RadGrid1_NeedDataSource"  

FilterControlAltText="Filter UnloadTypeColumn column"  

HeaderText="Unloading Type" ListTextField="_UnloadTypeName"  

ListValueField="_UnloadTypeName" UniqueName="UnloadTypeColumn">  

 

<HeaderStyle Width="100px" />  

 

<ItemStyle Width="100px" />  

 

</telerik:GridDropDownColumn>

please help.

thanks,
Minh Bui

Hi. This may not help any, but here's a sample of what I'm using. I'm having editing issues myself, but this is working fine to get the data:

<telerik:GridDropDownColumn DataField="store" HeaderText="Store" UniqueName="store" DataSourceID="SqlDataSource2"
       ListTextField="store" ListValueField="store">
</telerik:GridDropDownColumn>

<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:MyConnConnectionString %>"
    ProviderName="System.Data.SqlClient" SelectCommand="SELECT distinct store FROM [stores] order by store"></asp:SqlDataSource>

Of course it is using a SqlDataSource2 instead of the same SqlDataSource1 as the rest of the grid. I'm not sure how they would use the same data source. Anyway, I'm just figuring this stuff out myself, so this may not be of any help to you, but I tried.

Hi,

yes...this is to populate the dropdown during insert and update. I'm having problem getting the grid to come up with the original inserted value.

Hello Minh,

When in browser mode, GridDropDownColumn looks and behaves like a standard GridBoundColumn. When in edit mode, however, it displays a drop-down control for each edited cell in the column.

Thanks,
