While selecting an item from the dropdowntree control, items without children shows-up properly but those with child items don't have labels, including the child items. The <span class='k-in'> is empty, it is direct-child of <div class='k-bot'> which is under the <li role='treeitem'>.

I followed this example but omitted the second mapping because from the root parents to the children, they share the same structure. IEnumerable of my "TreeItem" class:

public class TreeItem<T>{

public T Item {get;set;}

public IEnumerable<TreeItem<T>> Children {get;set;}

public bool HasChildren {

get {

return this.Children != null && this.Children.Coun() > 0;

}

}

}

And here's how I configured the binding part:

@(Html.Kendo().DropDownTree()

.Name("Categories")

.BindTo(Model.CategoriesList, mapping => {

mapping.For<TreeItem<Category>>(binding => binding

.Children(c => c.Children)

.ItemDataBound((item, categ) => {

item.Expanded = true;

item.HasChildren = categ.HasChildren;

item.Id = categ.Item.Id;

item.Text = categ.Item.Name;

item.Value = categ.Item.Id.ToString();

})

)

})

.LoadOnDemand(false)

)

the Model.CategoriesList is IEnumerable<TreeItem<Category>> which makes it the same structure as the Children of the TreeItem<Category> in here, if it matters.

Hello,

I'm trying when exporting a Grid to excel file to format some columns raw content into hyperlink text. 

here is the implementation of my excelExport function:

What i tried to do first is to assign direct the value by changing the cell value which doesn't provide any result, 2nd problem, when debugging the columns 3, 4 and 5 aren't into my sheet object even with the showColumn and when downloading the excel file, like any of the operation above isn't take in consideration.

My Grid set Events like this:

The excel setting is like this:

Thanks in advance for your help !

Hi,

I have a kendo MVC grid with incell edit mode.

when i click  add new record and in new record row i have a autocomplete , cascading dropdown and normal dropdowns.

when i select values in first column and after move to second column then first column values are disappearing and again when i click on first column then values are showing in first column.

 I am using MVC Kendo UI. I have defined my grid in Razor

  1> I want to bind DataBound event of the grid in document ready function.
 but when i do that i get null reference.
 

I have a controller with code like this

public ActionResult Edit(int? id)
        {
            if (id == null)
            {
                return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
            }
            Assembly assembly = db.Assemblies.Find(id);
            var assemblyViewModel = new AssemblyViewModel
            {
                AssemblyId = assembly.AssemblyId,
                Description = assembly.Description,
                AssemblyItemMasterIds = db.AssemblyItems
                    .Where(w => w.AssemblyId == assembly.AssemblyId)
                    .Select(s => s.ItemMasterId)
                    .ToList()
            };

            return PartialView(assemblyViewModel);
        }

The view looks like this.

@(Html.Kendo().MultiSelectFor(model => model.AssemblyItemMasterIds)
                    .Name("AssemblyItemMasterIds")
                    .DataTextField("text")
                    .DataValueField("id")
                    .Placeholder("Select Items...")
                    //.AutoBind(false)
                    .DataSource(source => {
                        source.Read(read =>
                        {
                            read.Action("GetItemMasters", "ItemMasters");
                        })
                        .ServerFiltering(true);
                    })
                )

I have validated that the model is populated and that AssemblyItemMasterIds does have a list of the id's that should be selected.

If I click on the dropdown, the selected values populate.  Shouldn't they be populating without me having to that?

What am I missing?

Hi,

I have a model like below:

class Foo{

   public int id {get; set;}

   public string name {get; set;}

   public List<int> values {get; set;}

}

I would like to display the model with telerik grid as follow:

Id        Name       Jan-21    Feb-21   Mar-21

1          name1     10            20         30

2          name2     20            30         40

The Id is mapped to Foo.Id; Name is mapped to Foo.Name; Jan-21, Feb-21, Mar-21 are dynamic generated(in the future it will change) and the value is from the Foo.values.

I checked all the columns' example, telerik seems doesn't support such scenario. The model's field is supposed to be static and not supports List property.

Does anyone have a good idea to accomplish the feature? Many thanks in advance.

Best regards,

Ping

I have a kendo grid which pops up a custom template. All the fields are working correctly except the kendo button. I need it to be checked by default when the page pops up, but that does not happen when I use @Html.RadioButtonFor but it does get to the javascript.

If I use  @Html.Kendo().RadioButtonFor it does not get checked by default nor does it hit the javascript.

Is there something not right with the way I am calling the button

 <div class="form-group row">
            @Html.HiddenFor(model => model.MessageType)
            <div class="col-sm-4 k-edit-field">
                @Html.RadioButtonFor(model => model.MessageType, new { Checked = "checked", @id = "rad_system" })<span class="system_message">System Outage</span>

            </div>
            <div class="col-sm-4 k-edit-field">
                @Html.RadioButtonFor(model => model.MessageType, new { id = "rad_system_maintenance" })<span class="system_maintenance_message">System Maintenance</span>

            </div>
            <div class="col-sm-4 k-edit-field ">
                @Html.RadioButtonFor(model => model.MessageType, new { @id = "rad_news" })<span class="news_message">News</span>


            </div>

        </div>
