[Solved] Problem Getting Reference to Context Dictionary

[Rob]

Can somebody explain to me why I can't get a reference to the Context Dictionary in JavaScript in the OnClientSelectedIndexChanged event?  I am able to reference and set key values in the OnClientItemsRequesting event with the exact same code.

Here's what I have:

<telerik:RadComboBox runat="server" ID="ddlColorCode" AutoPostBack="true" EnableLoadOnDemand="True"
   OnClientSelectedIndexChanging="ddlSelIndexChanged"
   OnClientSelectedIndexChanged="ddlColorCde_SelectedIndexChanged"
   OnClientItemsRequesting="itmReq_ColorCde">
   <WebServiceSettings Method="loadColorCde" Path="~/WebServices/srvc_ComboBox.asmx" />
   <CollapseAnimation Duration="200" Type="OutQuint" />
</telerik:RadComboBox>

<script type="text/javascript">
            function itmReq_ColorCde(s,e){
                var context = e.get_context();
                var cb = $find("<%= Me.ddlColorCode.ClientID %>");
                context["ClrCde"] = cb.get_value();
            }
            function ddlSelIndexChanged(){
                  window.parent.FrameClearNodes();
            }
            function ddlColorCde_SelectedIndexChanged(s,e){
                var context = e.get_context();
                var cb = $find("<%= Me.ddlColorCode.ClientID %>");
                context["ClrCde"] = cb.get_value();
            }
</script>

Thanks.

Hi Dudeman,

This is by design. The get_context property is only available during the OnClientItemsRequesting event. You can use a temporary variable and store the required data there during the OnClientSelectedIndexChanged. Then during OnClientItemsRequesting you can use that variable to populate the context:

<script type="text/javascript">
var data = null;

function selectedIndexChanged(sender, args)
{
    data = "some data";
}

function itemsRequesting(sender, args)
{
   args.get_context()["Custom"] = data;
}
</script>
