    I have a mvc grid with as model { int projectnumber, int Monday }

    and code

    columns.Bound(c => c.Monday).Title(text: "Monday").ClientFooterTemplate(template: "#=sum#");

    .DataSource(datasource => datasource
            .Aggregates(aggregates =>
                aggregates.Add(a => a.Monday).Sum();

    Now I only want to create the sum over all lines in the grid with exception of the line with project number 1.


    The AJAX read gets back [1,1] and [2,4] and [3,5] So I hope to get a sum of 4+5=9 instead of the 10 I get with a normal sum.


    I hope myu question is clear and somebody knows how to do a partial sum.


    With kind regards,

    Maurice Lucas

    Hello Maurice,

    In order to implement the behavior you can use a JavaScript function to calculate the custom aggregates. Check out the following threads that discuss how this can be implemented.
