Hi,

Is it possible to stop the combo-box drop down from dropping down when a value is removed?

It can be reproduced on here http://demos.kendoui.com/web/combobox/api.html by selecting a value, highlighting it and pressing the delete key. The drop-down drops down, I would like to prevent that.

Because I have several drop-downs appearing above eachother and when the user is emptying the values, and trying to move to the next one down they are accidently selecting the values again. They can of course use tab and delete but I was curious as to whether this behaviour could be disabled.

Thanks
Emma

Hi everybody,

First of all, I'd like to say that I'm completely new to ASP.Net MVC and Kendo UI, and that I'm coming from the WPF world. That might give you some clues about the difficulties I'm facing here ;)

The scenario is quite basic, but I'm not able to achieve what I need to.
Let's image I have a form, that contains 4 search criteria.
- Start Date
- End Date
- Number
- String (city name)

From those 4 fields, I'm trying to feed a Grid in the same page (in AJAX), with data that is coming from an WCF webservice.

I've tried several ways to achieve this but everytime I'm facing a dead-en.

Here's a sample of my code.
The form:
The Grid :


JS Update method


Now the controller:

Obviously, when entering the Search Action, my iModel isn't updated with the latest data from the form. That's the main painpoint I have since the process I'm doing with the WCF service call doesn't have the correct Search criteria.

Hope I was clear enough !
Let me know if you're missing parts to give me a hand !

Thanks a lot !

Julien.

I'm wanting to put an HTML element in the HeaderTemplate() of a bound column.  I want to handle the click event of this HTML element.  This works fine as long as I have sorting turned off for the column.  However, if I have sorting turned on, then it seems that the grid automatically consumes the click of my HTML element and POSTs a sort on that column.  Is that by design?

If so, is there any way around it?  Turning off sorting for the column is not an option.  Is there a way to perform sorting from within the HeaderTemplate() that will also honor all other sorts/filters/paging/grouping on the grid?

If not that, is there a way to inject an HTML element via client-side code after the page has loaded that will not cause the column to sort when clicked?

I have tried both methods above but can't get them to work.  I'm hoping I'm missing something straightforward.

Hi,

I'am trying to create a dropdownlist with a guid as id : 

Dim dropDownListFor = _htmlHelper.Kendo().DropDownListFor(Of Integer)(_expression) _

  .BindTo(New SelectList(_collectionValeur, "Id", "Name")) _

  .HtmlAttributes(_attributsHtml)

Id is a Guid 
Name is a String

But I'm having the following error :

System.InvalidOperationException: Templates can be used only with field access, property access, single dimension array index, or single-parameter custom indexer expressions.

Any help please ?

i have a problem with a DropdownList control.
 i have a Grid with a popup edditing and when i show a popup the DropDownList doesnt show any data, im using MVC4 and KendoUI controls

this is the code.The Grid.

@(Html.Kendo().Grid<CashControl.Models.Usuario>()
.Name("grid")
.Columns(columns =>
{
columns.Bound(p => p.nombre).Width(100);
columns.Bound(p => p.nombreUsuario).Width(100);
columns.Bound(p => p.email).Width(100);
columns.Command(command => { command.Edit(); command.Destroy(); }).Width(160);
})
.ToolBar(toolbar => toolbar.Create())
.Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("DropDownListUsuarios"))
.Pageable()
.Sortable()
.Scrollable()
.HtmlAttributes(new { style = "height:430px;" })
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(20)
.Events(events => events.Error("error_handler"))
.Model(model =>
{
model.Id(p => p.idUsuario);
})
.Create(update => update.Action("EditingInline_Create", "Grid"))
.Read(read => read.Action("UsuariosRead", "Configuracion"))
.Update(update => update.Action("EditingInline_Update", "Grid"))
.Destroy(update => update.Action("EditingInline_Destroy", "Grid"))
)
)

The PopUp

<div class="demo-section" style="width: 250px;">
<h2>Products</h2>
@(Html.Kendo().DropDownList()
.Name("products")
.HtmlAttributes(new { style = "width: 250px" })
.DataTextField("nombre")
.DataValueField("idnombre")
.DataSource(source => {
source.Read(read =>
{
read.Action("UsuarioRead", "Configuracion");
});
})
)
</div>
<style scoped>
.demo-section {
width: 250px;
margin: 35px auto 50px;
padding: 30px;
}
.demo-section h2 {
text-transform: uppercase;
font-size: 1.2em;
margin-bottom: 10px;
}
</style>

and the Controller.

public ActionResult UsuarioRead([DataSourceRequest] DataSourceRequest request)
{
IQueryable<Usuario> products = CashControl.Usuario;
var rest = products.Select(n => new
{
idUsuario = n.idUsuario,
nombre = n.nombre,
nombreUsuario = n.nombreUsuario,
email = n.email
});

DataSourceResult result = rest.ToDataSourceResult(request);

return Json(result, JsonRequestBehavior.AllowGet);
}
and this is the JSON

result{"Data":[{"idUsuario":1,"nombre":"Eduardo","nombreUsuario":"Brakyo","email":"eduardomeji@gmail.com"}],"Total":1,"AggregateResults":null,"Errors":null}

Hi I am looking into building products using KendoUI MVC as potential tool in future. I have been messing around in the trial and for the most part it is fairly straight forward. I have run into one issue as follows.

I have a controller for a Contact. It has one view in particular, ViewDetails

It takes a list of contacts passed in as an array, assigns it to the viewdata and returns the View. This view has a KendoUI Grid in it and the code is as follows

The problem I am having occurs on line 35. When I try to assign the Data for "contactId", in the resulting javascript it appears that the only data is System.Int64[] like it called ToString on the data instead of taking the array and passing its contents as multiple named parameters.

The select function of course fails as there is not a proper contactId parameter passed, it is as follows for reference


Thanks for your assistance. This is one of the few snags I have seen reviewing the product, I hope to get it resolved so I can continue my evaluation in a timely fashion!

On my current project, we make extensive use of the kendo grids. However, I'm not happy with our re-use strategy, which consists of cutting and pasting known-good templates into each view that needs them. Is there documentation that describes how to, for instance, turn a template into a partial view? The trick is that, since these are client grids, I need to pass selection data into them somehow as well.

Here's a code example of what we're doing:
<script id="feedbackFormTemplate" type="text/kendo-tmpl">
@(Html.Kendo().Grid<Intranet.Data.Review.Info.FeedbackFormInfo>()
        .Name("CRTFeedbackForm_#=Pernr#")
        .Columns(columns =>
        {
           columns.Template(@<text></text>).ClientTemplate("<div>CRT Reviewed Date : \\#=SubmissionDateString\\# | \\#=CorrectiveActionName\\# | \\#=SectionName\\# </div>");
     
    })
        .ClientDetailTemplateId("crtReasonTemplate")
        .DataSource(dataSource => dataSource
            .Ajax()
            .Read(read => read.Action("CRTGetByInvestigatorAndCaseNumber", "FeedbackForm", new { pernr = "#=Pernr#", caseNumber=@Model.Case.CaseNumber }))
        )
        .Events(e => e
            .DataBound("hideHeader")
        )
        .ToClientTemplate()
            )  
</script>

<script id="crtReasonTemplate" type="text/kendo-tmpl">
     @(Html.Kendo().Grid<Intranet.Data.Review.Info.FeedbackFormReasonInfo>()
        .Name("reason_#=FeedbackFormId#")      
        .TableHtmlAttributes(new { @class = "noHideHeader" })   
        .Columns(columns =>
        {
            columns.Bound(p => p.ItemNumber).HtmlAttributes(new { style="width: 8%"});
            columns.Bound(p => p.ItemType).HtmlAttributes(new { style = "width: 8%" });
            columns.Bound(p => p.ItemOrg).HtmlAttributes(new { style = "width: 8%" });
            columns.Bound(p => p.ItemEventDateString).HtmlAttributes(new { style = "width: 8%" });
           
            columns.Bound(p => p.FeedbackReasonName).HtmlAttributes(new { style = "width: 45%" });
            columns.Bound(p => p.RebuttalStatus).HtmlAttributes(new { style = "width: 15%" });
        })
        .DataSource(dataSource => dataSource
            .Ajax()
            .Read(read => read.Action("GetReasonsByFeedbackFormId", "FeedbackForm", new { feedbackFormId = "#=FeedbackFormId#" }))
        )
        .ToClientTemplate()
    )
</script>

The bottom template in particular is re-used verbatim in many different places. I  tried doing this:

<script id="crtReasonTemplate" type="text/kendo-tmpl">
    @{ Html.RenderPartial("_CustomerReworkFeedbackReasonTemplate", new Intranet.Web.Areas.QTrack.ViewModels.CustomerReworkReasonTemplateViewModel { FeedbackFormId = feedbackFormId}); }
</script>

But it doesn't like the way I'm trying to transmit the feedbackFormId variable.

Thanks in advance for any assistance you can provide.

Dear KendoUI Team!
I hope you can help me out. I want to update some Editor Templates from the old Telerik Controls. I am using ASP.Net MVC 4.

My Editor Template looks like this


What I want to do is to set the value of the Textbox in the Change Event of the Combo-Box. My Approach is using .val()

$(elementName).val(e.sender.dataItem().Value);

The value displayed in the Textbox is changed then. BUT: The value transfered to the server is the old value of the Textbox.

Example:
The field has the value "US".  I edit the row.  I change the value to "CN" using the Combobox. "CN" is now displayed in the textbox in edit mode. When I want to update the row, "US" is provided as the value for the field in the model.

Is there a way to make kendoUI transfer the values that are displayed?

I'm getting a JavaScript error after I apply grouping.
Step 1. See attached Drag to GroupBy row.png - Load the page and group any column
Step 2. See attached JavaScript error when GroupBy.png, I get the JavaScript error.

The code I am using looks to me to be identical to the Custom AJAX Binding sample code included in the examples, but I am getting this error?

.CSHTML


Controller Code:
If anyone is interested I have a Visual Studio 2012 Sample App to show the error download here: https://skydrive.live.com/redir?resid=3113F9DB92CC84B2!1997&authkey=!Nefhm5WSin4%24

Refer to the attached Highlighted VS solution items.png for the highlighted items of interest.

Thanks,

Can someone point me to an example of using the GroupFooterTemplate with the MVC Server Wrappers?

From what I can tell, this should work when I 'group by' any column:

Is there any other setup / configuration that's needed to make it work?

Edit:
I've add this to the DataSource as well without success
