Hi,

I am using Kendo Tree View.
I construct a HierarchicalDataSource, but I get a 'stack overflow' error when I try to call SetDataSource to bind the data.
I get this error in IE 8.0.7601.17514CO 64bit, and no error in chrome.

here is my code:

public class TDNode
    {
        public string id { get; set; }
        public string text { get; set; }
        public string ctrlTypeCssClass { get; set; }
        public bool expanded { get; set; }
        public bool hasChildren { get; set; }
        public string parentid { get; set; }
        public List<TDNode> items = new List<TDNode>();
    }

 success: function (data) {
                var newDataSource = null;
                newDataSource = new kendo.data.HierarchicalDataSource({
                    data: data
                });

                $("#tvtemplate").data("kendoTreeView").setDataSource(newDataSource);
            }

Thanks.

In our JS onClick event we have the following code:

        var grid = $("#MyGrid").data("kendoGrid");
        var row = grid.select();

When running on IE (test on versions 9, 10, 11) the row is null if the row isn't specifically selected before clicking on the button. Any work around for this?

thanks

Bill

I need to know how to properly build a gridtemplatecolumn in code behind.

@(Html.Kendo().Grid<DealViewModel>().Name("Grid").AutoBind(false).Scrollable(x => x.Height("auto")).Columns(columns =>
                                                                                                              columns.AutoGenerate(a =>
                                                                                                              {
                                                                                                                  a.Encoded = false;
                                                                                                              })).Columns((columns) => Utilities.SetColumnProperties(columns.Container.Columns, @ViewBag.CurrentStepId)).Sortable(x=>x.SortMode(GridSortMode.SingleColumn))

the second columns call the SetColumnProperties method where I query the database to get the columns properties that are set by the user as follows.

/////////////
/////////////
/////////////


public static void SetColumnProperties(IList<GridColumnBase<DealViewModel>> columns, Guid currentStepId)
{
var column = ContextHelper.Context.SalesStep.Find(currentStepId).Column.ToList();
var columnsToAdd = new List<GridColumnBase<DealViewModel>>();

columns.ForEach(x =>
{
var currentColumn = column.FirstOrDefault(y => y.ColumnName.Name.Equals(x.Member, StringComparison.InvariantCultureIgnoreCase));

x.Visible = currentColumn != null;
var gridBoundColumn = x as IGridBoundColumn;
if (gridBoundColumn == null || currentColumn == null)
{
return;
}
//TASKS ENABLED
if (x.Member.Equals("TaskTo"))
{
x.Visible = TaskingUtilities.TaskingEnabled;
}

if (new List<string>
{
"TaskTo",
"TakeOwnership",
"ReturnButton",
"RejectTask",
"CompleteTask",
"Approve",
"ApproveTo",
"Deny",
"DenyTo"
}.Contains(x.Member))
{
var claims = ClaimsPrincipal.Current.Claims;
var firstOrDefault = claims.FirstOrDefault(y => y.ValueType.Equals(currentStepId.ToString()));
if (firstOrDefault != null)
{
var enumString = firstOrDefault.Value;
SedonaSalesWorkflow.StepAccessLevel returnVal;
var stepAccessLevel = Enum.TryParse(enumString, true, out returnVal) ? returnVal : SedonaSalesWorkflow.StepAccessLevel.None;

x.Visible = stepAccessLevel == SedonaSalesWorkflow.StepAccessLevel.Full;
}
else
{
x.Visible = false;
}
}




if (currentColumn.Width != 0)
{

x.Width = currentColumn.Width.ToString(CultureInfo.InvariantCulture) + "px";
}
gridBoundColumn.Hidden = currentColumn.IsHidden;
gridBoundColumn.Title = currentColumn.Title;
gridBoundColumn.Format = currentColumn.Format;
gridBoundColumn.Filterable = currentColumn.Filterable;
gridBoundColumn.Sortable = currentColumn.Sortable;
gridBoundColumn.Groupable = currentColumn.Groupable;                
});

Now how do I add a GridTemplateColumn correctly.  I can get it to show but I want to build a column dynamically from code behind.  There is basically one grid that users can add/remove fields to and create a new page and then set properties on that field which is why this is done this way.  I would like to basically concatenate columns of a certain type.

This currently does not work
columns.FirstOrDefault().Grid.Columns.Add(new GridTemplateColumn<DealViewModel>(columns.FirstOrDefault().Grid, model => model.Approve)
            {
                ClientTemplate = "#= Approve #"
            });

Thanks for the help.

Hi, 

I'm using the numeric text box as follows: 


The model property 'MaintenanceYearlyAmount' has the following attributes for validation: 

When testing this I get the following results: 

• I enter 999.56 - It rounds up to 999.60 (Why is it showing the additional zero at the end when I've specified only 1 decimal?)
• I enter 1111 and tab off the control - I get a valid validation message of 'Please enter a value less than or equal to 1000' AND it automatically changes the value to 1000 (is there a way to stop this from happening? The user should be warned, but it's there responsibility to change the value not to have it automatically changed. They might have entered 9845 accidentally adding the 5 at the end and instead of just deleting the 5 they have to type the number out again. 
• I remove the Range validation and keep only the Required validation.  
  
  • I delete the current value for MaintenanceYearlyAmount and for Full Name (which is a normal Microsoft textbox and is required in the model) and click save. - Full name correctly shows its validation message, but the Kendo numeric textbox doesn't. This is where the problem is. I'm not sure why the client side validation doesn't fire correctly or show the validation message. If I add the Full name value back and click submit/save again, Full name passes, the form submits and server side validation fails sending the form back with the correct message under the MaintenanceYearlyAmount input. So bottom line is that the validation works server side, but not client side for the Required Validator. 

I have tried to follow the Kendo example (http://demos.telerik.com/aspnet-mvc/grid/filter-menu-customization) but I am clearly missing something...

The grid loads data just fine. The javascript function `costCenterNumberFilter(element);` is executed as I have placed an `alert("blah");` and that is displayed in the browser...

It will not render the AutoComplete for cost center number filter. Any help will be greatly appreciated.

Is there a spell checker for MVC?
If not will there be one soon?

Hi.  I would like to know if there is any way to delay a clicked tab from displaying until my corresponding MVC controller action is completed?  The following code below calls an MVC controller "Controller" with the ActionResult "ControllerAction" and "message" is the name of the tab I am displaying for validation.
Currently, I have a function called within the if statement if(a_tabPageSelected == "MyTab") which takes a while to complete and would prefer if the tab section didn't appear until the function completes.

Controller.cs

public ActionResult ControllerAction(string a_tabPageSelected)

{

   if(a_tabPageSelected == "MyTab")

   {

        /// do stuff before tab page appears

   }

 

/// now display tab page using some command and return View

return View("Tabsection");

View.cshtml 

i have a Kendo grid that uses an edit Popup. The culture in the client is de-DE, when an user tries to edit a decimal number i.e. 8,5 Kendo sends a null to the server for that value and returns validation message "The value 8.5 is not valid for 'PropertyName'". Any help will be greatly appreciated.

@{
var culture = System.Globalization.CultureInfo.CurrentCulture.ToString();
}

<script src="@Url.Content("~/Scripts/Kendo/cultures/kendo.culture." + culture + ".min.js")"></script>

jQuery.extend(jQuery.validator.methods, {

return this.optional(element) || kendo.parseDate(value) != null;
},

}
});
@(Html.Kendo().Grid<SalesToolkit.ViewModels.AdminEquipDimViewModel.Equipment>()

)

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult EquipDim_Update([DataSourceRequest] DataSourceRequest request, AdminEquipDimViewModel.Equipment equipMfg)
{
if (equipMfg != null && ModelState.IsValid)
{
AdminEquipDim oEquipMfg = new AdminEquipDim();
oEquipMfg.UpdateEquipDim(equipMfg);
}

return Json(ModelState.ToDataSourceResult());
}

I was told that this new release will contain a new Export to Excel Widget from the MVC Grid.

Is that true?
If so where can I find documentation about it.
Thanks

I haven't been able to figure out how to set the series with a data source returned from a controller (see below). What do I need to pass to series.Line()?

The controller method returns a list of long integers.

        @(Html.Kendo().Chart()
            .Name("jobHistoryChart")
            .Title("Batch Job History")
            .Theme("Bootstrap")
            .Legend(legend => legend.Visible(true).Position(ChartLegendPosition.Bottom))
            .HtmlAttributes(new
            {
                style = "margin-top:15px; border:thin solid steelblue; padding:10px; padding-bottom:20px;"
            })
            .DataSource(dataSource => dataSource.Read(read => read.Action("GetBatchJobHistory", "Home",
                new { histJobCaption = "Load Inventory Usage Summary Data" })))
            //.Series(series =>
            //{
            //    series.Line().Name("Batch Job");
            //})

        )
