    How to prevent WCF service from running second time for SelectCount event? I use GetDataAndCount method, however I can see that
    WCF service is called twice for some reason...

    Could it be because of additional custom parameter, that I had to add into databinding (as in your example), so GetDataAndCount is not 'recognized' as a method to be called once?

    Addition: it's ok now, I had to add additional parameter directly into javascript method, because DataBinding event is not fired for some reason.

    Now the problem is that WCF service ignores cookieless session from ASP.NET site.

    Hello Alexander,

    When the GetDataAndCount method is used the RadGrid client-side data binding you get both data and total items count in a single request. I am sending you a simple example which demonstrates this. Also on the following link I attached a small video which shows that there is only one request. More information about Client-side binding you could find on the following documentation article:

    Additionally on the following links you could find information about: WCF and cookieless sessions

    I hope this helps.

    All the best,
