Questions on UI for ASP.NET AJAX Forum

Hello!

I am using a RadComboBox with automatic load on demand from an ObjectDataSource, using a "contains" filter to fetch matching records from the datasource. It works very well, with one exception. If I load the page, than leave it in the browser for ten minutes or so, and then try again, the combobox is stuck in the "loading" state, and stays there permanently. If I reload the page again, everything works fine again.

I've tried upping the session timeout but that had no effect on the issue. I would be grateful for help on this.

Best regards,
Kalle

OnItemsRequested Event Not Available on Server side

I have 3 cascading combo boxes which may be populated when the page loads based upon request string item values or they may be populated by the user on the client side.

Because of this "dual personality", I am trying to "clear" the events on the combo boxes at page_load in case any of the combo boxes are loaded based on the incoming request string. Then I want to restore the events as my code exits page_load (I hope this is the correct way of handling this problem).

The three (3) combo boxes are defined as:

<asp:TableRow>

<asp:TableCell>

<asp:Label ID="Label1" runat="server" Text="<% $GetLangString:NewTrans.InThisCountry %>"></asp:Label>

</asp:TableCell>

<asp:TableCell>

<telerik:RadComboBox ID="SearchCountry" TabIndex="5" style="z-index: 9000;" Width="200px" EnableEmbeddedSkins="true" Skin="Sitefinity" runat="server" Height="150px" OnClientSelectedIndexChanging="LoadSearchStateProv">

</telerik:RadComboBox>

</asp:TableCell>

</asp:TableRow>

<asp:TableRow>

<asp:TableCell>

<asp:Label ID="Label3" runat="server" Text="<% $GetLangString:NewTrans.InThisState %>"></asp:Label>

</asp:TableCell>

<asp:TableCell>

<telerik:RadComboBox ID="SearchStateProv" TabIndex="6" style="z-index: 9000;" Width="200px" EnableEmbeddedSkins="true" Skin="Sitefinity" runat="server" Height="150px" OnClientSelectedIndexChanging="LoadSearchCity" OnClientItemsRequested="SearchItemsLoaded" OnItemsRequested="SearchState_ItemsRequested">

</telerik:RadComboBox>

</asp:TableCell>

</asp:TableRow>

<asp:TableRow>

<asp:TableCell>

<asp:Label ID="Label4" runat="server" Text="<% $GetLangString:NewTrans.InThisCity %>"></asp:Label>

</asp:TableCell>

<asp:TableCell>

<telerik:RadComboBox ID="SearchCity" TabIndex="7" style="z-index: 9000;" Width="200px" EnableEmbeddedSkins="true" Skin="Sitefinity" runat="server" Height="150px" OnClientItemsRequested="SearchItemsLoaded" OnItemsRequested="SearchCity_ItemsRequested"></telerik:RadComboBox>

</asp:TableCell>

</asp:TableRow>

My problem is this...on the display page (pagename.aspx), the second and third cascading combo boxes have values entered for the "OnItemsRequested" event. But when I try to "clear" this value in the server side code at page_load I keep receiving a compilation error on the event. You may refer to the attached screen capture that shows the error.

Why is this event property inaccessible on the server side?

Thanks in advance!
