Hello,

Here is the situation. I have a treeview that basically represents directory, sub-directory and files. For some reasons, I can't use the LoadOnDemand option. So I load all the tree in my controller.
Everything works fine except that it seems the Databound event is triggered for each directory and subdirectory. I was expecting the event to be triggered only once when all data are "loaded" from the datasource.
At the end, I need to expand some nodes everytime the datasource is refreshed

This is my treeview

@(Html.Kendo().TreeView()
.Name("treeview")
.DataTextField("name")
.LoadOnDemand(false)
.DataSource(datasource => datasource.Read(read => read.Action("Tree_Read_All", "MyController"))
.Model(model => model.Children("childrens")))
.DragAndDrop(true)
.Events(events => events
.Select("treeViewOnSelect")
.Drop("treeViewOnDrop")
.DataBound("treeViewDataBound")
)
)

Thanks in advance

Set the height of a row dynamically

Hello,

Is is possible to set the height of a row after the databound ?
Let me explain why. Sometimes I have a lot of events and sometimes I don't. So I want to set the height of the row after the databound so I can show all the event in the row. The attached file will clarify my mind I think.

Thanks in advance for your response.

How do I set the value to a model value in a template?

I have a popup editor template with an editor in it and I'm trying to figure out how to set the value to the model field value. I have :

@(Html.Kendo().Editor()

.Name("Body")

.HtmlAttributes(new { style = "width: 590px;height:440px" })

.Value(@Model.Body)

)

But that does not work. Anyone know the answer?

Hi All,

I am new to MVC ,so if i am wrong sorry in advance.
My application have one telerik grid. it contains several columns,
one column is ajax action link (productid),it displays a partial view within the same page. upto this it works fine.
Now when i sort the telerik grid colum, it hides this partial view.
Below is my view:

@model IEnumerable<MvcApplication2.Models.Product>@{
ViewBag.Title = "WebgridSample";
}<h2>WebgridSample</h2>
@using Kendo.Mvc.UI;

<script src="/Scripts/MicrosoftAjax.js" type="text/javascript"></script>
<script src="/Scripts/MicrosoftMvcAjax.js" type="text/javascript"></script>

@{
MvcApplication2.Models.Product product = new MvcApplication2.Models.Product();
}
<script src="~/Scripts/jquery-1.7.1.min.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
@Scripts.Render("~/bundles/jquery")

@Html.DisplayNameFor(model => model.Quantity)
</th>
<th></th>
</tr>@(Html.Kendo().Grid(Model).Name("ProductGrid")
.Columns(columns =>
{columns.Template(@<text>
@Ajax.ActionLink(@item.Id.ToString(), "Edit",
new { id = @item.Id,name=@item.Name,desc=@item.Description,quantity=@item.Quantity }, new AjaxOptions { HttpMethod = "GET",
InsertionMode = InsertionMode.Replace ,
UpdateTargetId = "view-details"

})
</text>)
.Title("Id");
columns.Bound(o => o.Name);
columns.Bound(o => o.Description);
columns.Bound(o => o.Quantity);
})
.Pageable()
.Sortable()
)
<div id="view-details" >

</div>

and my controller action is given below:

public PartialViewResult Edit(string id)
{Product product = inventoryList.Single(t => t.Id == id);
return PartialView("_Product", product);
}

and my partial view is:

@model MvcApplication2.Models.Product
@{
Layout =null;
}<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />

</head>
<h2>Product Details</h2>
<body>
<table ><tr><td><label>Id:</label></td><td>@Html.TextBox("Id", Model.Id)</td></tr>
<tr><td><label>Name:</label></td><td> @Html.TextBox("Name", Model.Name)</td></tr>
<tr><td> <label>Description:</label></td><td> @Html.TextBox("Description", Model.Description)</td></tr>
<tr><td><label>Quantity:</label></td><td> @Html.TextBox("Quantity", Model.Quantity)</td></tr>
</table>

</body>
</html>Thanks in advance :)

Gantt Databound issue and timeline headers style

Hi,

I am using Gantt and I have few issues.

1. When Gantt is first loaded it doesn't display task timeline. I have to select some other view first in order for it to appear.
2. If I use databoud event to set view ( var gantt = $("#Gantt").data("kendoGantt");
gantt.view("week"); ) I have error Uncaught RangeError: Maximum call stack size exceeded. if i comment this all code in databoud function executes fine

Is there any way to hide weeks if view is set to month view? Our client wants just to track by months since all projects are monthly.
Also can we hide days or hours if week and day view is selected.

Thank You

Dropdownlist with cascade and filter

Hi guys,

It’s possible to make a control dropdownlist with settings cascade enabled and filtered by contains too. I show you the scenario:

Grid code

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

.Name("fare_details#=FareID#")

.ToolBar(t =>

{

if (User.IsInRole("Modify"))

{

t.Create().Text("Afegir Referencia");

}

})

.Columns(columns =>

{

columns.ForeignKey(f => f.Tipus, (System.Collections.IEnumerable)ViewBag.CatalogTypes, "Key", "Value").EditorTemplateName("CustomGridForeignKeyFareType").Width(120);

//columns.ForeignKey(f => f.CatalogReference, (System.Collections.IEnumerable)ViewBag.Cataleg, "Reference", "Descripcio").EditorTemplateName("CatalegReferenceByType");

columns.Bound(f => f.CatalogReference).EditorTemplateName("CatalegReferenceByType").EditorViewData(new { gridid = "fare_details#=FareID#" });

Editor template

@model object

@(Html.Kendo().DropDownList()

.Name("CatalogReference" + ViewData["gridid"])

.HtmlAttributes(new { data_bind = "value:CatalogReference" })

.AutoBind(false)

.OptionLabel("Select reference...")

.DataTextField("Descripcio")

.DataValueField("Reference")

.Filter(FilterType.Contains)

.MinLength(3)

.ValuePrimitive(true)

//.HtmlAttributes(new { data_skip = "true", data_bind = "defferedValue: object" })

//.BindTo((SelectList)ViewData[ViewData.TemplateInfo.GetFullHtmlFieldName("") + "_Data"])

.DataSource(source =>

{

source.Read(read => read.Action("PopulateReferences", "Catalog").Data("filterTypes"))

.ServerFiltering(true);

})

.CascadeFrom("Tipus")

.HtmlAttributes(new { id = Guid.NewGuid().ToString() })

)

function filterTypes() {

return {

text: $("#Type").data("kendoDropDownList").value() + "|" + $("#CatalogReference" + temporalFare).data("kendoDropDownList").filterInput.val()

};

}

$("#CatalogReference" + temporalFare).data("kendoDropDownList")
Here, I find the error. Browser say me this expression is undefined

Controller Code

public JsonResult PopulateReferences(string text)

        {

            var param = text.Split('|');

            var type = (int)text[0];

            var search = text[1];

            var catalog = GetCatalog((catalogType)type).Where(c => (c.Descripcio + " " + c.Reference).Contains(search)).Select(c => new { Reference = c.Reference, Descripcio = c.Descripcio + " - " + c.Reference }).AsQueryable();

            return Json(catalog, JsonRequestBehavior.AllowGet);

        }

I hope this is helpful code.

Thanks in advance.

Xavier.

Example of use with legacy .Net code-behind project

Hello,

I have used Kendo with MVC projects, and quite like it.

Part of my evaluation is how easy it would be to retrofit a couple grids into legacy code-behind projects.

Can I use the .Net helpers? Or do I have to use the pure HTML/Javascript methods?

Being an MVC guy, I have not sent JSON to/from on a code-behind project before... In MVC the JSON is automatically converted into your viewmodel type onthe backend, if you C# class aligns with the JSON data. Is the same possible with CodeBehind?

Is there a simple example of a kendo grid using .net code-behind?

Thanks,

~S

Dropdown List not selecting initial value/text

The following dropdownlist will not ever select any item except for the first (index 0):

var clientList = HtmlExtensionMethods.GetClients().Select(c => new SelectListItem { Text = c.Value, Value = c.Key }).ToList();

@(Html.Kendo().DropDownListFor(model => model.ClientID)
.Name("ClientID")
.BindTo(clientList)
.DataTextField("Text")
.DataValueField("Value")
.Value(Model.ClientID)
.Text(Model.ClientName)
.HtmlAttributes(new { @class = "select wfull" })
)

I have tried removing the Value and Text methods and adding .SelectedIndex(2) which does not work either. The model.ClientID is a value in the selectlistitem. How in the world can I get this dropdown to select the item with the value from model. Nothing seems to work.
