Hi 

I like to highlight one cell per row then get the highlighted cell and set a value to another cell on the same row.

for Question 1 ,A is selected so if that's the correct answer then "Raw score" column has to be set to 1

user can only one of A,B,C,D or No answer per row.

is this possible?

Thanks

Faz

Hi Faz,

Is the Grid configured for incell editing? If this is so you can use the cellClose event handler to update the Raw Score model property depending on another model property using the set() method. For example:

            cellClose: function(e) {
              if(e.model.Discontinued === true) {
                e.model.set("UnitsInStock", 1)
              } else {
                e.model.set("UnitsInStock", 0)
              }
            }

Here is a Dojo demo demonstrating this: https://dojo.telerik.com/INaMODEh

Let me know if you have any questions.

Thanks for the reply Nikolay.

Decided to implement checkbox to achieve this, however I'm not sure how to get currently editing row on checkbox click event.

I have to find  eg: when B is clicked  then find if C also is checked or not. for each row I need to do this and update a column on the same row depending on the combination.

this is my ClientTemplate for checkbox

 columns.Bound(c => c.AnswerB).Title("B").Width(80).ClientTemplate("<input id='AnswerB' name='chk' class='checkbox' type='checkbox' value='#=AnswerB#' # if (AnswerB) { # checked='checked' # } # onclick='onAnswerClick(this)'/>");

and click handler


    function onAnswerClick(me) {
         var grid = $("#AnswersGrid").data("kendoGrid");
        var row = $(this).closest("tr");
        var dataItem = grid.dataItem(row);
        console.log(row)
        console.log(dataItem) <---- Is Null

   }

dataItem is returning null so  I cannot check other columns on the row.

Can you please let me know how this can be achieved?

 

Thanks

Faz
