Hi, 

I am using two kendo tree views in my screen. The trees are taking long to load.  Each of the tree has around 200 nodes with checkbox. I added .LoadOnDemand(true), but not of much help. 

I am populating treeviews models in C# and passing it to the razor views. I am attaching my treeview's razor files (CasTradeOrgnTreePartial.cshtml and CasTradeDestTreePartial.cshtml) and C# procedure (populate_tree_model_C#_procedure.cs) . 

Please advise, how to speed up the tree loading time.

Regards, 

Manoj

Hi - I just have a list of strings to bind.

I get the list from splitting a comma separated list...

I want the list of selected values posted to the server:


All I get is the first selected value, not all selected values...

Any ideas?

Been working on this for too long now. I have a detail grid where one of the columns is not editable by the user. It's value is calculated based on values in other fields/columns. If the user changes one of these, a stored proc is ran on the server that updates the calculated field. I have verified that the database is updated correctly. The problem is the grid is not refreshing/rebinding unless i force a datasource read (reload page, change pages in grid , etc.) . I know this is something silly on my part; maybe someone can point out my problem.

Here is my grid definition: 


Here is my saved event handler for the grid : 


The line e.sender.dataSource.sync() forces the update action method to be called on the server. Here's that action method:


The repository's ApplyLots method just calls a stored proc on the database, and update the db context of the repository.

Any suggestions?

We have just downloaded the latest July release of Kndo wrappers for MVC . We are trying to test them side by side with the MVC extensions however we get the following error when building the project after adding reference to the Kendo dll

'SliderTickPlacement' is an ambiguous reference between 'Telerik.Web.Mvc.UI.SliderTickPlacement' and 'Kendo.Mvc.UI.SliderTickPlacement'

You do say that it is possible to use  Kendo  within the same project. Would appreciate clarification.
Many thanks

Hi,

I recently started working on Asp.Net MVC and also very new to Telerik UI for asp.net mvc. I created a new telerik mvc project and set the authentication mode to windows in web.config. The application runs fine on my PC. But when I upload it on to a windows server, it gives me a 'Resource not found' error indicating that it is missing login.aspx file. Is there another way to set the authentication mode to windows and get the application working in Telerik UI?
Please help.

Thanks.

Here is a screen shot of my all. Validation are not working on Kendo Upload control used.



View has code:


 <div class="col-md-4">
                    @Html.Label("file", "Select File")
                    @(Html.Kendo().Upload()
                          .Name("upload")
                          .Multiple(false)
                          .Messages(msgs => msgs.Select("Browse"))
                          )
                   @Html.ValidationHtmlMessageFor(model => model.UploadFileName)
                </div>
                <div class="col-md-4 buttonBox">
                    @Html.Kendo().Button().Name("Save").Content("Upload File").HtmlAttributes(new {type = "submit"}) 

Code in View Model:

    [Required(ErrorMessageResourceType = typeof(Resources.Resources),
                  ErrorMessageResourceName = "FieldRequired")]
        [Display(Name = "Month")]
        public int ObjectiveMonth { get; set; }

Controller checks for ModelState.isValid

But the validation message do not show up

What could the reason be?

Number of records to display should be a drop down with the number of users they would like to view per page. The default number should be 10 records. I want the selection criteria should be in denominations of 10 up to 40. (10, 20, 30, 40) 

Code in View:

@(Html.Kendo().Grid<IncentiveViewModel>()
            .Name("Incentive")
            .Columns(columns =>
            {
                columns.Bound(p => p.Make).EditorTemplateName("MakeDropDown").Sortable(true);
                columns.Bound(p => p.Model).EditorTemplateName("ModelDropDown").Sortable(true);
                columns.Bound(p => p.Year).Sortable(true);
                columns.Bound(p => p.Term);
                columns.Bound(p => p.Rate);
                columns.Bound(p => p.StartDate).Format("{0:MM/dd/yyyy}");
                columns.Bound(p => p.EndDate).Format("{0:MM/dd/yyyy}");
                columns.Bound(p => p.IsActive).ClientTemplate(
                    "# if (IsActive) { #" +
                        "Yes" +
                    "# } else { #" +
                        "No" +
                    "# } #"
                    );
                columns.Template(@<text></text>)
                    .Width(110)
                    .ClientTemplate(@"<a class=""k-grid-delete"" href=""\#""></a>");
            })
            .ToolBar(toolbar =>
            {
                toolbar.Create().Text("Add Incentive");
                toolbar.Save().SaveText("Save Changes").CancelText("Cancel Changes");
            })
            .Editable(editable => editable.Mode(GridEditMode.InCell))
            .Resizable(resize => resize.Columns(true))
            .Pageable(pageable => pageable
                .Refresh(true)
                .PageSizes(true)
                .ButtonCount(10))
            .Navigatable()
            .Sortable()
            .Resizable(resize => resize.Columns(true))
            .DataSource(dataSource => dataSource
                .Ajax()
                .Batch(true)
                .PageSize(10)
                .ServerOperation(false)
                    .Events(events => events.Error("ds_onError").Sync("incentivesDs_onSync").RequestEnd("ds_onRequestEnd"))
                .Model(model =>
                {
                    model.Id(p => p.IncentiveId);
                    model.Field(p => p.Year).Editable(true);
                    model.Field(p => p.Make).Editable(true);
                    model.Field(p => p.Model).Editable(true);
                    model.Field(p => p.Rate).Editable(true);
                    model.Field(p => p.StartDate).Editable(true);
                    model.Field(p => p.EndDate).Editable(true);
                    model.Field(p => p.IsActive).Editable(false);
                })
                .Create("Create", "Incentive")
                .Read("Read", "Incentive")
                .Update("Update", "Incentive")
                .Destroy("Destroy", "Incentive"))
                .Events(events => events.SaveChanges("incentivesGrid_onSaveChanges").Edit("grid_onEdit"))
         )

Even with this setting I see a paging drop down with 5, 10, 20 where as I want 10, 20, 30, 40..etc

Here is the result:

 

I am allowing my users to select rows in a kendo grid via a checkbox in the first column and right now the selections are lost if/when they change pages.  I was hoping there would be a way i could show a confirm dialog when when they click the page, but before the page changes and either
1) allow them to perform an action on the selected rows
2) lose the selections
3) stop the page change from occurring

I am having trouble actually stopping the page change from happening.  Are there any samples on how to do this?

Thanks,

I have tried following the Validation Guide and the Batch Editing example but something is still amiss. The validation tooltip does not appear when I attempt to Save Changes after leaving a required field empty (i.e. Rate). We are using ASP.NET MVC 4 Razor and Kendo UI 2014.1.415.

CSHTML


ViewModel (abbreviated with just one field)

I noticed that no validation attributes are being appended to the input field:


What am I missing? What more do you need to see? Thanks.

Hi,

Is there the way to hide all the times grid and just keep "All Day" row, since visits in my project are whole day events?

I have tried to set business hours to the same time, it didn't worked for me.

Any suggestion?

Thank you,
-Yuriy
