Hii,

I am creating grid view in application using dev express. I have created partial view for grid according to demo application of dev express. I have binded grid successfully but I stucked in problem. How can I pass parameter in java script function from grid view (partial view). my code is like that:
   

settings.HtmlRowPrepared = (s, e) =>
        {
            MVCxGridView g = s as MVCxGridView;

            index = g.PageIndex;

            //settings.ClientSideEvents

            pageCount = g.SettingsPager.PageSize;

            //pageCount = g.PageCount;
        };
and 
I am calling function :

[C#]
settings.ClientSideEvents.EndCallback = "Micrograph";

This function I have declared on main view.
But I am unable to access parameter "index" and "pageCount" in method of micrograph.

 function Micrograph() {
var currentIndex= index;
var totalRow= pageCount;
}

Please help me I couldn't get value of index and pageCount. 
Thanks in advance.

What I have tried:

settings.HtmlRowPrepared = (s, e) =>
{
MVCxGridView g = s as MVCxGridView;

index = g.PageIndex;

//settings.ClientSideEvents

pageCount = g.SettingsPager.PageSize;

//pageCount = g.PageCount;
}; for this I have tried custom js properties of dev express:

settings.CustomJSProperties = (sender, e) =>
{
var gridview = sender as MVCxGridView;

gridview.JSProperties["cpCurrentVal"] = index;


gridview.JSProperties["cpPageSize"] = pageCount;

};
but I didn't get value in javascript function on main view.
