CancellableCallbackEventArgs not known

Hi there,

I am trying to procedd your examples given on your online-documentation version 5.1.1 about callbackpanel.

if I doubleclick in the properties of a callbackpanel to the CallbackRefresh-event, an error occurs "Property value is not valid", an the codebehind shows that
"Syncfusion.Web.UI.WebControls.Tools.CancellableCallbackEventArgs" is not known.

What am I doing wrong?

Found the solution by myself: when drag-n-dropping the callbackpanel-control, no reference to syncfusion.shared.web was added.

btw: why not?
after adding it the error disappeared.

I find it a bit confusing and anoying that there are so common and same-sounding or indifferent namespaces like Syncfusion.Tools.Web and the subnamespaces itself (like the on above) are in other namespaces or sound mix-merged

e.g.
Syncfusion.Tools.Web and Syncfusion.Shared.Web have both SubNamespace: Syncfusion.Web.UI.WebControls.Tools...

Hi Sascha,

I apologize for the delay in responding.

I am afraid that I was not able to reproduce the issue. Please refer to the following steps that I tried to reproduce it.

1. Drag-n-dropping the callbackpanel-control
2. syncfusion.shared.web will also be added
3. doubleclick in the properties of a callbackpanel to the CallbackRefresh-event
4. But No Error.

Here is the video clip for your reference:

Please have a look at the above Video clip and let me know if I am missing some thing. And also, kindly Re-initialize Visual Studio.NET Toolbox and then create the application and let us know if the problem still exists.

Thanks,
Melba
