preventDefault in awebeginload

Title:

BI{code} ?

Hello, I want to validate a search form and load related grid only if validation is successed. Something like this: $myGrid.on('awebeginload', function (event, requestData) { if ($myForm.valid()) { // push search params to requestData } else { event.preventDefault(); // doesn't work } }); How can I stop the grid from loading?

  I'm guessing you're using `.Parent` to bind the form controls to the grid, you could instead on search click use grid's api and call `api.load({ params: { Name: 'Foo', Par1: $('#id').val(), ... })` or you could use `.DataFunc("searchFunc")` instead of `.Url`, and do the validation on the client: function searchFunc(g) { // validate here; you may use var gp = utils.getGridParams(g) if you want, or validate $('#id').val() directly if(!valid){ return null; } return $.post('@Url.Action("GetItems", "LunchGrid")', g).then(function(model) { return model; }); }
