Get ID when a custom command is clicked in Kendo grids

Quick code tip for getting the row data from a custom command button in Kendo UI grids. This is useful for intercepting a delete event or any custom actions you have set up on a Kendo grid.

    function grid_deleterow(e) {
        var row = $(e.currentTarget).closest("tr");
        var data = $("#grid").data("kendoGrid").dataItem(row);
        var id = data.EntityId;

In the JavaScript function above, id will contain the value of the EntityId column for the row of the custom button clicked. This is great because you don’t have to make your grid selectable for this to work.

Here is how the event would be triggered when using the Kendo MVC wrappers:

             .Columns(columns =>
                 columns.Bound(p => p.Field1);
                 columns.Command(command => command.Custom("Delete").Click("grid_deleterow"));

Displaying inactive foreign keys in Kendo UI grids with In-Cell editing

Foreign key columns in Kendo UI are pretty great. With in-grid editing, you can use them to display a choice of categories, people, and so on. At some point you may need to mark a category as inactive or disabled, so that the user can no longer select that foreign key as a valid choice. So how do you display old deactivated foreign keys in your Kendo grid for record keeping purposes?

By selecting the foreign key text value into our grid as a hidden column, we can use that to resolve any deactivated foreign keys. Here is the JavaScript function that will display the text equivalent of the foreign key, and use the hidden column as a backup source for inactive foreign keys.

    var collection;
    function getforeignkeytext(rowData) {

        if (!collection) {
            var grid = $("#grid").data("kendoGrid");
            var foreignKeys = grid.options.columns[2].values; // Set the FK column index
            collection = {};
            for (var i in foreignKeys) {
                collection[foreignKeys[i].value] = foreignKeys[i].text;

        var result = collection[rowData.CategoryId];
        if (result == undefined) {
            result = rowData.CategoryName;
        return result;

For our grid to use this, use a client template for the foreign key column set to use the function above. I am using the MVC server wrappers in this example.

columns.ForeignKey(p => p.CategoryId, Model.CategoryDropdown, "Value", "Text")

Why go through all that trouble when something simple like .ClientTemplate("#=CategoryName#") would display the hidden column value? That solution won’t correctly display an edited value, before the user saves the grid when using GridEditMode.InCell.

So what about when editing the cell? It would be super nice if the dropdown also magically contained the inactive foreign key as a choice only for that cell. That would really complete the user experience. With a second JavaScript function we can take care of that.

    function editforeignkey(e) {
        var valueToAddToDropdown = e.model.CategoryId;
        var textToAddToDropdown = e.model.CategoryName;

        var dropdown = e.container.find('[data-role=combobox]').data();

        if (typeof dropdown != "undefined") {
            var valueExists = false;
            for (var i = 0; i < dropdown.kendoComboBox.dataSource._data.length; i++) {
                if (dropdown.kendoComboBox.dataSource._data[i].Value == valueToAddToDropdown) {
                    valueExists = true;
            if (!valueExists) {
                dropdown.kendoComboBox.dataSource.add({ Text: textToAddToDropdown, Value: valueToAddToDropdown });

The function above is triggered on the Kendo grid’s edit event. It attempts to find the foreign key value in the cell’s dropdown, and adds it if necessary. The value will be automatically selected.

There does appear to be one limitation. If the user changes an inactive foreign key value to an active one, and the cell loses focus, then the inactive foreign key can no longer be reselected, unless all grid changes are cancelled.

With this technique you can provide users with a cohesive experience for Kendo grids containing historical foreign key data.
