Need a RADGrid sample with ComboBoxes

[Clement]

Need a working sample of Multiple comboboxes in a RadGrid with All Editing functions.

We have a requirement of using the RadGrid for Bill of Materials where two columns need to have ComboBoxes and the 2nd combobox should populate data based on the 1st combobox selection.

Pls help

Thanks

Hi Clement,

Thanks for the link Princy and i appreciate your help !

Our Problem in Detail :

We added a Hierarchy Grid and added Master and Details View and everything was working fine with SQLDataSources.

We added EditFormSettings with our own Template and we wanted to add Multiple Combo Boxes (same as Multiple ComboBox example). So that when users select the Seal Type, SealCode is populated in the Combo Box 2.

Our Problem started here :

We are getting the following Error :

1. The name 'RadComboBox1' does not exist in the current context

2. The name 'RadComboBox2' does not exist in the current context

My Structure of the RADGrid is :

Master Table
        <EditFormSettings>
                RadComboBox1
                RadComboBox2
        </EditFormSettings>
    
        Details Table (0)

        Details Table (1)

            Details Table (1,0)
   
We are not able to access the RadComboBox 1 and 2 from the codebehind file.

Looks like we are missing the right way to reference it.

We followed the Update/Delete/Insert Hierarchy Grid Example ( http://www.telerik.com/DEMOS/ASPNET/Prometheus/Grid/Examples/DataEditing/ThreeLevel/DefaultCS.aspx ) ; which used automatic posting BUT we tried to add EditMode = EditForms and to complicate things, two comboboxes that are related and the value from the Table which gets populated is having ID (SealTypeID, SealCodeID) But when we open it for editing we should show the Description for users and while Update or Insert we need to pass the ID for the Tables.

Hope u understand the issue....

Please advice and please find our project files at http://www.telerik.com/ClientsFiles/087200_TelerikTest.zip 

We are stuck and i need help since this is the first program we are working with RAD Controls.

Thanking u in advance !

Hi Clement,

Try adding the ComboBoxes inside the FormTemplate tag as shown below.

ASPX:

<EditFormSettings EditFormType="Template"  >
 <FormTemplate>
     <telerik:RadComboBox ID="RadComboBox1" runat="server">
     </telerik:RadComboBox>
     <telerik:RadComboBox ID="RadComboBox2" runat="server">
     </telerik:RadComboBox>
 </FormTemplate>
</EditFormSettings>

Thanks
Shinu.

Hi Clement,

Can you try moving the Javscript code snippet from the FormTemplate and see whether it is working properly?
