Hello, 

I'm having an issue with the check box function of the igGrid.

When deselecting the check box the row is staying selected.

i have tried the deselect method, but this also fails.

i get the following error in both scenarios "Uncaught TypeError: Cannot read property '0' of null "

I'm using the 2014 vesrion of the grid.

 jquery 1.9 and jquery ui 1.11.1.

this is my code

<script>
jQuery(function($) {
$('#grid1').igGrid({
dataSource: '@Url.Action("dataset-binding")',
autoGenerateColumns: false,
columns: [
{ hidden: true, key: "FirmIdString", template: "${FirmIdString}" },
{ hidden: false, key: "CanSelectForExtraction", template: "${CanSelectForExtraction}" },
{ headerText: "Firm Name", key: "FirmName", template: "${FirmName}", width: "65%" },
{ headerText: "Status", key: "StatusDescription", template: "${StatusDescription}", width: "15%" },
{ headerText: "Request Id", key: "StagingDatabaseId", template: "${StagingDatabaseId}", width: "15%" },
{ headerText: "Request", key: "RequestId", template: "${RequestId}", hidden: true }
],

$("#grid1").igGridSelection("deselectRow", 0);
// $("#grid1").igGridSelection("clearSelection");
}

if (record == null || (ui.newState == "on" && record.CanSelectForExtraction != true)) {

return false;
}

return true;

}

}

});
