Hello Choung Tran,

Formula function is used in combination with unbound columns so it won't work in your case. Sometime ago we added a second param to the formatter function so you should be able to use it if you have some of the newer versions of the product. What is the version of your product?
To check the product version execute the following code in the browser JavaScript console:

$.ui.igGrid.version 

You can also check whether the following code works for you:

column.For(Function(x) x.Actions).HeaderText("Actions").width(100).FormatterFunction("CheckAction")

function CheckAction(value, row){
                        return row["CusipID"];
                    }

Edit: I misspelled the name of the method. Instead of "Formatter" it should be "FormatterFunction". Sorry for the inconvenience.

Hope this helps,

can you help me!!

i want to call function from column of gridview to handle process value of column, i am used to FormatterFunction but it can be only 1 paremater, i want to get other column of gridview

my code:

column.For(Function(x) x.Actions).HeaderText("Actions").width(100).Formula("CheckAction")

function CheckAction(data,grid){
                        return data["CusipID"];
                    }

it not work

I actually figured out after further investigation using your answer by doing the following.

Thanks for your help,

column.Unbound("Download").Formula("testIG");

<script>

function testIG(data,grid)

{

return data["DocumentId"];

}

</script>

Thanks for the response.  This seems to be what I am looking for. I am using the grid in a MVC application.  Can you tell me how this should be written in that scenario?

For instance, I have the following just to test that the javascript function testIG gets called.  But it does not and I am not sure of the correct syntax as I would think it would be correct following the example you provided above.

column.Unbound("Download").HeaderText("Download").Formula("function(data,grid){return testIG(true)}");
