Bug in Sales Dashboard Example

[Nick]

I was playing with the dashboard recently and trying to adapt it to an alternate datasource but after trying to track down a problem I was encountering I noticed that it's actually a problem in the Sales Dashboard example itself. When you click on a person's name the silverlight controls in the main content area all update based off of an employee id being access in the Javascript, but the silverlight controls don't update correctly on the first attempt.

Sales Dashboard Example

If you open up the example, you'll get metrics for the first peron in the list, Nancy. And the Representative Sales of that first pair of data points is $7,332 (first green bar). If you select the next person over (Andrew), you'll notice the Rep Sales total of that first green bar stays at $7,332, it doesn't update at all. But if you select Andrew again, it NOW updates and shows the correct value of $3,099. After playing with the code that drives this I came to the conclusion that although the content for the main panel is being updated via using AJAX, the page is not correctly updating the Id that is stored in Javascript for access by the silverlight controls.

My question is, given this problem (if I'm right) how would you fix it? I mean, aren't the examples supposed to show working demos ;-)

Hi,

I was able to replicate the described issue. We will updated the sample application in a few days and will fix the problem.

I have updated your Telerik points as a token of gratitude.

Hi Nick,

We are updating the Sales Dashboard application to Q1 2011 version of the controls. The new version of the application will be available for download the next week.
And issue was due to a client-script in the Statistics user control not evaluated properly when the control is loaded dynamically with ajax. The problematic function is:

function getChartEmployeeID()
{
    return <%= EmployeeID %>;
}

We changed the method to:

function getChartEmployeeID()
{
    return getEmployeeID();
}

And added the following code in the Default.aspx.cs file:

protected override void OnPreRenderComplete(EventArgs e)
{
    base.OnPreRenderComplete(e);
    // Make the EmployeeID available to scripts
    ScriptManager.RegisterStartupScript(Page, typeof(Page), "employeeID",
        "function getEmployeeID()   { return " + EmployeeID + "; }", true);
}

All the best,
