Grid missing data-k in html table row
Title:
B
I
{code}
?
...Continuing my journey to my task on the Grid with checkboxes. I tried to implement the "get selection" button to show in a div span area just like the demo did. The checkboxes works fine on display but no luck to get the selection going with empty getting the selected value on click for the javascript to run. After a through checking I found that there's an attribute "data-k" missing on each tr datarow, below is an extract of the the row: My grid's TR: `<tr data-lvl="1" data-g="GridChkPersistent" data-i="1" class="awe-row awe-alt awe-selectable">` Demo's TR: `<tr data-k="1999" data-lvl="1" data-g="GridChkPersistent" data-i="1" class="awe-row awe-alt">` I tried to trouleshoot its event on its change event by adding an alert as below: grid.on('change', chkSel, function () { var chk = $(this); var isChecked = chk.val() === 'true'; var key = chk.closest(rowsel).data('k'); if (isChecked) { alert(chk.closest(rowsel).data('k')); vals[key] = 1; } else delete vals[key]; }); The demo can prompt its id as it should and mine is undefined. So my question is how can I get grid to generate that data-k for the grid?

you need to set the `Key` in the `GridModelBuilder`, as you can see in our demos: `KeyProp = o => o.Id` or `Key = "Id"` an example here also: https://www.aspnetawesome.com/learn/mvc/Grid#Data-binding
