Hello all,

I am relatively new to the Kendo UI suite, so I need some assistance in an application I'm working on.  I'm using Visual Studio 2010, MVC3.  I will do my best to explain my situation and the problem I'm trying to solve.

I'm trying to handle the login process for my application using a popup window that is raised by a link in the main browser window.  On my main screen, I have an Html.ActionLink that opens the view for the logon page (screen shot #1).  This is a simple view with one link.  The logon view contains the definition for the Kendo window, so the username/password entry screen is then presented as a modal popup (attached screenshot #2).  When the logon link on the main page is clicked, the Kendo window opens as a popup without any issues, and I can enter the user and password.   If the entered user and password is correct, the popup closes and the controller code redirects the user to the application's main menu of options in the browser window, as expected.  The problem arises when the user/password fails validation, because the popup window still closes, and the resulting "invalid login" message is displayed in the main browser window.  I'm trying to keep the popup open after the submission, and display the error within the popup, so the user can try again (simulated in screen shot #3).

All of the logic for the Kendo window definition exists in the logon view, not the main view.  Also, I'm not sure which pieces of code to post in helping to clarify this, but I will gladly do so if it helps me to resolve the problem.  So, in a nutshell, how do I keep my logon popup window open and have it receive the results of an invalid user/password submission, rather than have it close and the results sent to the main browser window.

Thanks in advance,
Bob

I like the ImageUploader.

So can I use it on its own ?

I was thinking maybe hide the editor and have a button which would exec the appropriate command to open the ImageUploader control.  
So effectively it would work as an image file manager.

Is  this possible ?

We have a page with Kendo UI grid and simple search field with Kendo UI Autocomplete inititated on it. Search field has a placeholder "Type resource key".

On any version of internet explorer, when user navigates grid using pagination, the "GetResourceValues" function, that populates grid, gets search field's placeholder value as request parameter:

sort=&page=2&pageSize=25&group=&filter=&language=-&searchKeyword=Type+resource+key&resourceType=

While in other browsers the request looks like this:

sort=&page=3&pageSize=25&group=&filter=&language=-&searchKeyword=-&resourceType=

This leads to empty grid results after using pagination. Can it be Kendo UI bug?

Here is part of the code:

@(Html.Kendo().Grid<ResourceViewModel>()
          .Name("resourcesList")
          .Events(e => e.DataBound("handleDataBound"))
          .Pageable()
          .Resizable(resizable => resizable.Columns(true))
          .ClientDetailTemplateId("resourceDetailsTemplate")
          .DataSource(dataSource => dataSource
                                        .Ajax()
                                        .Events(events => events.Error("errorHandler"))
                                        .ServerOperation(true)
                                        .Batch(false)
                                        .Model(model => model.Id(res => res.Id))
                                        .Create(create => create.Action("CreateResource", "Resources"))
                                        .Update(update => update.Action("UpdateResource", "Resources"))
                                        .Destroy(destroy => destroy.Action("DeleteResource", "Resources"))
                                        .Read(read => read.Action("GetResources", "Resources").Data("searchCriteria"))
                                        .PageSize(25))
          .Sortable()
          .Scrollable()
          .ToolBar(factory =>
                   factory.Template(@<text>
        <div class="k-grid-toolbar-row">
            <input id="resourceSearch" class="k-grid-toolbar-search-field" />
        </div>
    </text>)))

<script>
    $(document).ready(function () {
        var autocompleteSymbol = $("#resourceSearch").kendoAutoComplete({
            dataTextField: "Key",
            minLength: 2,
            dataValueField: "Key",
            filter: "contains",
            placeholder: "Type resource key",
            dataSource: {
                type: "json",
                transport: {
                    read: "Resources/GetAutoComplete",
                    maxRows: 50000
                }
            },
            change: filterResources
        });
    });
</script>

I want to use the mvc wrappers grid filter to select a sub group of data, and then use that data to send a sms. How do access that data using  on the server?
Thanks

I have a list view that supports viewing and deleting attached files.  That works just fine.  The problem I am having is when I try to add a new file to the list.  I have a custom editor template for the AttachedFile object, but when the editor runs the Model passed into it is empty.  I have specified a default value on the field that I need to access in editor template, which I would assume would be passed to the editor.  

Here is my ListView:
Here is my EditorTemplate:
The problem is the Model.EntityTableKey is empty in the editor.  

What am I doing wrong?  Shouldn't the default value be passed to the editor template?

Hello,

I have a combobox that I want to implement server filtering on - I have followed the example in the demo but I cannot get the filter to work, the items bind correctly upon selecting the dropdown but the autocomplete filter doesn't filter.   The filter works perfectly clientside but not when I implement serverfiltering.   Am I missing something on the controller end?

Hi,

I have a datepicker on my cshtml view.  I'm creating it with the following line (which I'm using elsewhere successfully):
@Html.Kendo().DateTimePicker().HtmlAttributes(new { @id = "fltBeginDate" }).Value(DateTime.Now).Format("MM/dd/yyyy")
When the view tries to load, I get the following error:
Value cannot be null.
Parameter name: key

Hi,

I'd like to report a few possible issues with the asp.net mobile framework. I'm saying possible, as I'm not sure if my application is setup completely correctly.

1.  Whenever my .ServerNavigation is set to true, the transitions between views (i.e. "fade") stops working. It just flicks between pages without any effect.
2. I'm trying to implement a drawer in one of my views, but this does not seem to work either when the .ServerNavigation is set to false. It seems to duplicate my url, so that the application does not quite understand where to navigate. I.e. when ServerNavigation is set to true, my links look like the following: "http://localhost/Stimline.Xplorer.Mobile/UnitDetails/Index/1#/". Both the drawer and "back" button seems to work correctly with this in place. Now, if i change my ServerNavigation to false, the link will look like the followng after presssing the "back" button once and navigate back to the view again with a link: "http://localhost/Stimline.Xplorer.Mobile/UnitDetails/Index/1#/Stimline.Xplorer.Mobile/UnitDetails/Index/1". As a result of this, both my drawer and "back" button stops working.

We used to iterate over DataSourceRequest filters like this:
foreach (var filter in request.Filters)
{
          var descriptor = filter as FilterDescriptor;
          if (descriptor != null)
          {
               //do stuff
           }
}
Since we moved to Q3(v2013.2.906) this simple solution no longer works. With 2 or more filters applied to datasource, requestFilter is single CompositeFilterDescriptor with 2 children, CompositeFilterDescriptor and FilterDescriptor, and so long.
Is this a feature or a bug? If this is a feature is there any elegant solution to 'do stuff' or turn it off and get back to good old FilterDescriptor collection?

Right now we're using crude recursion to preprocess the filters, but that does not feel quite right. ;-) 

Hi,
The Mobile ListView Filtering demo explains how to filter a datasource on a single field. I'm looking to filter a directory of users on two fields - I want to return a list of users when either their firstname OR surname starts with a search argument.

Looking at forum posts for the Web ListView widget, it appears you can specify multiple search fields and associated logic condition (eg. And, Or).

1. Does the Mobile ListView Filterable configuration allow you to specify two filter fields?
2. If so, what would be the syntax to achieve this using the Mobile ListView MVC wrapper?
