Client-Side progressData Object Doesn't Work

[Don]

I've written a client-side javascript method to handle the OnClientProgressUpdating event for my ProgressArea.  The signature looks as follows:

 

 

    function progressUpdating(progressArea, args) {

 

 

          alert(args.get_progressData().RadUpload.RequestSize);

 

 

However, I can't seem to get any information for the "RadUpload" object.  When I inspect the "args" object using the debugger, here is what it contains:

 

     ? args.get_progressData()

     {...}

     CurrentOperationText: "Uploaded SendACHFile.txt"

     InProgress: true

     PrimaryPercent: "1"

     PrimaryTotal: "588480"

     PrimaryValue: "8192"

     ProgressCounters: true

     SecondaryPercent: "1"

     SecondaryTotal: "588480"

     SecondaryValue: "8192"

     TimeElapsed: "00:00:01s"

 

Where is the RadUpload object?  This does not match the documentation.  There are supposed to be additional properties.  How can I get access to the "RadUpload" object?

The above code throws the following exception:
    Microsoft JScript runtime error: 'get_progressData().RadUpload.RequestSize' is null or not an object

Hi Don,

The OnClientProgressUpdating client event fires for both the ProgressArea and the ProgressManager. The event arguments have different methods depending on which is the sender. Please subscribe to the OnClientProgressUpdating event of the progress manager to get that properties working.

I am already subscribing to that event:

 

<telerik:RadProgressArea ID="RadProgressArea1" runat="server" DisplayCancelButton="False"

 

 

OnClientProgressUpdating="progressUpdating" ProgressIndicators="TotalProgressBar, TotalProgress, TotalProgressPercent, RequestSize, FilesCountBar, FilesCount, FilesCountPercent, SelectedFilesCount, TimeElapsed, TimeEstimated">

 

and the javascript method is as follows:

 

<script type="text/javascript">

 

 

function progressUpdating(progressArea, args) {

 

alert(args.get_progressData().RadUpload.RequestSize);

As previously stated, the "RadUpload" property does not exist.  Please advise.

Thanks

I may have found the answer to this issue.  I am using a custom progress area, and not the file upload progress area.  When using a custom progress area, it looks like the file properties associated with the progressData object do not exist.

Is there a way to extend the progressArea class such that I can add my own custom properties to it?

Hello Don,

You can add your custom properties to the progress area the following way:

<script type="text/javascript">
            Telerik.Web.UI.RadProgressArea.prototype.ob = new Object();
            Telerik.Web.UI.RadProgressArea.prototype.ob.a = 5;
        </script>

and then use the added property like this:

<script type="text/javascript">
            function progressUpdating(sender, args) {
                alert(sender.ob.a);
            }
        </script>

I hope this help you get started.

The custom property listed below is scripted on the client at runtime.  Is there a way to get to this property on the server side at run time?  I need to b e able to pass structured information from the server back to the client, to update a custom progress monitor that uses a template.

Hi Don,

If I have understood you correctly, you want to script a client side property from the ServerSide. Is that correct? You can do that in the following way:

StringBuilder sb = new StringBuilder();
  sb.Append("Telerik.Web.UI.RadProgressArea.prototype.ob = new Object();");
  sb.Append("Telerik.Web.UI.RadProgressArea.prototype.ob.a = 5;");

ClientScript.RegisterStartupScript(this.GetType(), "Page_Load", sb.ToString(), true);

This is very trivial example, however you can register whatever you want, even complex object serialized using JSON.
