How to fix "x is a variable but is used like a method" syntax error in C#?

Question

I am getting the following error working on gradrid footer totals "'fitem' is a 'variable' but is used like a 'method'"

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item is GridFooterItem)
    {
        GridFooterItem fitem = (e.Item as GridFooterItem);
        string value1 = fitem("CALENDAR_DAYS_MTD").Text;
        string value2 = fitem("WEEKENDS_MTD").Text;
        string value3 = fitem("HOLIDAYS_MTD").Text;
        string value4 = fitem("BUSINESS_DAYS_MTD").Text;
        int footervalue1 = Convert.ToInt32(value1.Split(':')[1]);
        int footervalue2 = Convert.ToInt32(value2.Split(':')[1]);
        int footervalue3 = Convert.ToInt32(value3.Split(':')[1]);
        int footervalue4 = Convert.ToInt32(value4.Split(':')[1]);
        //to get the value only.
        if (footervalue2 + footervalue3 + footervalue4 > footervalue1)
        {
            fitem("WEEKENDS_MTD").Style("color") = "Black";
            fitem("HOLIDAYS_MTD").Style("color") = "Black";
            fitem("BUSINESS_DAYS_MTD").Style("color") = "Black";


        }
        else
        {
            fitem("WEEKENDS_MTD").Style("color") = "Red";
            fitem("HOLIDAYS_MTD").Style("color") = "Red";
            fitem("BUSINESS_DAYS_MTD").Style("color") = "Red";
        }
    }
}

You could have at least tagged your question with the library you are using. Looks like Telerik or something. — Darin Dimitrov

I removed the Telerik tag. This has nothing to do with Telerik (assuming that GridFooterItem was not somehow a magical subclass of Func, which it is not .. object x = new object(); x("foo") would have resulted in the syntax error.) — user166390

I am getting an 'IndexOut of Range Exception' on the string conversion any ideas? — user406151

Your lines

fitem("WEEKENDS_MTD").Style("color") = "Black";

should probably be

fitem["WEEKENDS_MTD"].Style["color"] = "Black";

since the [] brackets are for accesing an index and the () brackets are used to call methods.

You have this:

 GridFooterItem fitem = (e.Item as GridFooterItem);
 string value1 = fitem("CALENDAR_DAYS_MTD").Text;

Using fitem("CALENDAR_DAYS_MTD") likely should be fitem["CALENDAR_DAYS_MTD"].

As long as you're using C#, you should be using square brackets rather than parenthesis for referencing indexes.

fitem["WEEKENDS_MTD"].Style["color"] = "Black";

VB.NET uses the parenthesis for indexes.

@Servy - Yep. Meant to type it but apparently my fingers didn't listen to my brain.

I think you're thinking of VB.NET, which uses parentheses to index, but this is C#. It should be:

fitem["CALENDAR_DAYS_MTD"].Text // Note the square brackets replacing the parens.

Not:

fitem("CALENDAR_DAYS_MTD").Text
