Hello,

When the jQuery val() method is used, the value of the input is visually changed. However, in order to have the same value applied in the model, you would have to manually trigger the change method so it would be indicated that the respective model's property has to be updated with the value of the input. Therefore, the provided suggestion above should be utilized:

$('input[id="Name"]').live('change keyup', function () {
   var urlSegment = $('input[id="UrlSegment"]');
   urlSegment.val("Test");
   urlSegment.change();
});

Good afternoon,

I am having this same issue, but using '.change()' isn't resolving the issue for me. I'm not sure what else to do.

I am auto filling a name and email textbox based on available users in the domain.

var Name = $('input[id="Name"]');

var Email = $('input[id="Email"]');

Name.bind("on keyup", function (e) {

var UN = $(this).val();

$.ajax({

cache: false,

type: "GET",

contentType: "application/json; charset=utf-8",

dataType: 'json',

url: url,

data: {"UserName": UN },

success: function (results) {

if (results) { alert("SUCCESS: " + results); }

var res = results.split(",");

var email = res[0];

var name = res[1];

if (name) {

Name.val(name);

Name.change();

Email.val(email);

Email.change();

}

},

error: function (xhr, ajaxOptions, thrownError) {

alert("AJAX error");

}

});

For some reason the name field gets posted successfully but email is always null even though I get the text I need in the textbox.

here is my grid

@(Html.Kendo().Grid<vmPurchasingList>()

.Name("PurchasingList")

.Columns(columns =>

{

columns.Bound(c => c.Name);

columns.Bound(c => c.Email);

columns.Bound(c => c.StepsString);

columns.ForeignKey(c => c.CostCenterId, (System.Collections.IEnumerable)ViewData["UsersCostCenters"], "Id","Name")

.Title("Cost Center");

columns.ForeignKey(c => c.StepsId, (System.Collections.IEnumerable)ViewData["Steps"], "Id", "Type")

.Hidden(true);

columns.ForeignKey(c => c.StepsHwyId, (System.Collections.IEnumerable)ViewData["StepsHwy"], "Id", "Type")

.Hidden(true);

columns.Command(command => { command.Edit(); }).Width(160);

})

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(20)

.Events(events => {

events.Error("error_handler");

events.Sync("reload");

})

.Model(model =>

{

model.Id(c => c.Id);

model.Field(c => c.Id).Editable(false);

model.Field(c => c.Name);

model.Field(c => c.Email);

model.Field(c => c.CostCenterId).DefaultValue(1);

model.Field(c => c.StepsId).DefaultValue(0);

model.Field(c => c.StepsHwyId).DefaultValue(0);

})

.Create(create => create.Action("Create", "Home"))

.Read(r => r.Action("Read", "Home"))

.Update(update => update.Action("Update", "Home"))

)

.ToolBar(toolbar => toolbar.Create())

.Editable(editable => editable.Mode(GridEditMode.PopUp))

.Events(e => e.Edit("onEdit"))

.HtmlAttributes(new { style = "height:700px;" })

)

I am also having the same issue with the drop down lists when I attempt to 'clear' a users selection based on another drop down list.

Thank you, that did the trick. I implemented my code above inside the onEdit(event) call for my popup editing so my code was slightly different. I needed to update the model and the text of the textbox.

function onEdit(event) {

var model = event.model;

var Name = $('input[id="Name"]');

var Email = $('input[id="Email"]');

Name.bind("on keyup", function (e) {

var UN = $(this).val();

$.ajax({

cache: false,

type: "GET",

contentType: "application/json; charset=utf-8",

dataType: 'json',

url: autoFillUrl,

data: {"UserName": UN },

success: function (results) {

if (results) { alert("SUCCESS: " + results); }

var res = results.split(",");

var email = res[0];

var name = res[1];

if (name) {

Name.val(name);

Email.val(email);

model.Name = name;

model.Email = email;

}

},

error: function (xhr, ajaxOptions, thrownError) {

alert("AJAX error");

}

});

}
