Hi all,
I have just started developing with telerik and am having an issue with the autopostback.
I have a ddl with 3 columns; when the user selects an option from the ddl the page should postback and I would expect it to use the server-side SelectedIndexChanged method.
It postbacks, loading the Page_Load, though does not hit my SelectedIndexChanged method.

My Code:
<%@ Register TagPrefix="rad" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %> 
 
            <rad:RadComboBox ID="ddlAccount" Skin="WindowsXP" runat="server" Height="190px" AutoPostBack="true"
                Width="300px" EnableEmbeddedSkins="false" > 
                <ItemTemplate> 
                    <table style="text-align: left;"
                        <tr> 
                            <td style="width:175px;"
                                <%# DataBinder.Eval(Container,  "DataItem.AccountName") %> 
                            </td> 
                            <td style="width:75px;"
                                <%#DataBinder.Eval(Container, "DataItem.City")%> 
                            </td> 
                            <td> 
                                <%#DataBinder.Eval(Container, "DataItem.IsTarget")%> 
                            </td> 
                        </tr> 
                    </table> 
                </ItemTemplate> 
            </rad:RadComboBox>   

Code behind:
    Protected Sub ddlAccount_SelectedIndexChanged(ByVal o As ObjectByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles ddlAccount.SelectedIndexChanged 
 
      'My code here.... 
 
    End Sub 

I have tried adding  OnSelectedIndexChanged="ddlAccount_SelectedIndexChanged" to the aspx side though with no difference.

Can anyone help?

Thanks in advance

OK,
I carried on working on this problem, and have managed to get it to work.
Adding teh DataTextField & DataValueField seems to have fixed it!

            <rad:RadComboBox ID="ddlAccount" Skin="WindowsXP" runat="server" Height="190px" AutoPostBack="true" 
                Width="300px" EnableEmbeddedSkins="false" MarkFirstMatch="true" HighlightTemplatedItems="true" DataTextField="AccountName" DataValueField="AccountID"
                <ItemTemplate> 
                    <table style="text-align: left;"
                        <tr> 
                            <td style="width:175px;"
                                <%# DataBinder.Eval(Container,  "DataItem.AccountName") %> 
                            </td> 
                            <td style="width:75px;"
                                <%#DataBinder.Eval(Container, "DataItem.City")%> 
                            </td> 
                            <td> 
                                <%#DataBinder.Eval(Container, "DataItem.IsTarget")%> 
                            </td> 
                        </tr> 
                    </table> 
                </ItemTemplate> 
            </rad:RadComboBox>

Hello rich,

We tried to reproduce the reported issue on our side, but to no avail. I think it will be best if you can open a support ticket and send us a simple running project (incl. CSS, images, skins, DB backup if needed and so on) demonstrating the problem (and step-by-step instructions on doing so). In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.

Thanks beforehand for your patience and cooperation,
Paul
