[Solved] How to set a max rows on telerik grid (MVC, Razor)

[Cameron]

Is there a way to set a maximum of rows on a grid?
For example, i just want to let a customer introduce 15 rows max or a minimum of 1.

Hello Cameron,

This should be possible if you implement the following checks when items are inserted or deleted in the grid data source:

• When new items are inserted, validate whether the items in the grid source are less than 15. If not, cancel the insert operation and display a user-friendly message to indicate that the action was aborted.
• When the user attempts to delete a grid item, verify that there is more than one item in the grid. If not, cancel the delete operation and display a user-friendly message to inform the user that the action was aborted.

Try this out and let me know if I am leaving something out.

Yes indeed! It works for me. i did this:

.ClientEvents(x => {
    x.OnEdit("CheckRows");
    x.OnDelete("CheckRows"); })

<script>
 function CheckRows(e) {
        var grid = $('#Grid').data('tGrid');
        var button = $("#Grid .t-grid-toolbar .t-grid-add");
        if (grid.insertedDataItems().length - grid.deletedDataItems().length > 15) {
            button.hide();
        }else{
               button.show();
        }
    }
</script>
