RadHTMLChart Dynamic DataSource?

[Ryan]

Hi,

I have a radhtml column chart that i want to change the datasource of based on the selected values of 2 dropdown lists.  i am using a radscriptmanager and have the dropdown lists listed as update controls (see code below), however when the page posts back, it loads nothing in the chart area...no x or y axis or anything. 

is it possible to update the data source of a radHTML chart dynamically?

HTML: 
<telerik:RadScriptManager ID="RadScriptManager1" runat="server" EnablePartialRendering="true" ScriptMode="Release">

    </telerik:RadScriptManager>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

    <AjaxSettings>

       <telerik:AjaxSetting AjaxControlID="ddlAssetType" EventName="SelectedIndexChanged" >

        <telerik:AjaxSetting AjaxControlID="ddlChart" >

            <UpdatedControls>

                <telerik:AjaxUpdatedControl ControlID="rcStats" />

            </UpdatedControls>

        </telerik:AjaxSetting>

        <telerik:AjaxSetting AjaxControlID="ddlRange" >

            <UpdatedControls>

                <telerik:AjaxUpdatedControl ControlID="rcStats" />

            </UpdatedControls>

        </telerik:AjaxSetting>

    </AjaxSettings>

</telerik:RadAjaxManager>

and this is what i am calling on the backend:

 rcStats.DataSource = list

        rcStats.DataBind()

any help would be greatly appreciated!

Thanks,

Ryan

Hi Ryan,

Your RadAjaxManager declaration is not correct, you have extra AjaxSetting opening tag. Your settings should look like this:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="ddlAssetType" EventName="SelectedIndexChanged">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="rcStats" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="ddlRange">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="rcStats" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
