Hidden column, ClientGroupHeaderTemplate and Export to Excel not working properly

Hi all,
I have a grid with a couple of columns with a ClientGroupHeaderTemplate set.
If the columns are visible, then ExportToExcel command works properly, but when I try to hide these columns ( .Hidden(true) ), exporting resets the header defined by me and shows the default one (Column name: value) in the exported file.
How can I show the ClientGroupHeaderTemplate if I want these columns hidden?

Issue with individual column sorting in Telerik MVC grid

Hi

I am using Telerik(Product Version 2012.3.1018.340) MVC grid for my project. When I am setting initial Sort configuration with multiple columns, It have an issue with individual column sorting. The individual column sorting is not at all working in my grid

It is working fine if I didn't set initial sort order (ie, if i give just ".sortable()"). But i want to set initial sort order also individual column sort order functionality

I tried with operation mode is client. Then for one time the sorting is happening only for anyone column which we clicked first. Next time when we try to click on any other column to sort it won't work.

I used the following code in my project, please help me to tackle this issue

view

Html.Telerik().Grid<MyApplication.MainApplication.Models.ApplicationModel.ApplicationViewModel>().Name("Grid1")

.Columns(col =>

{

col.Bound(c => c.UserID).ClientTemplate(

"<a href='" + Url.Content("~/Index/Details/") + "<#= UserID #>' title='Details' class='lnkDetails'><#= Number #></a>"

).Title("Number").Filterable(false);

col.Bound(c => c.FirtName).Filterable(false);

col.Bound(c => c.LastName).Filterable(false);

col.Bound(c => c.RID).Hidden();

col.Bound(c => c.Active).Filterable(false).ClientTemplate(

"<input type='checkbox'" + "<#= Active?\"checked\":\"\" #>" + " OnClick='return false' />"

).Width(115);

col.Bound(c => c.StartDate).Filterable(false).Format("{0:d}").Width(115);

col.Bound(c => c.CloseDate).Filterable(false).Format("{0:d}").Width(112);

Draggable chart series points

Hi,

We have a requirement of implementing charts, so that series points can be adjusted by dragging them.
Here is an example of desired chart behavior: http://jsfiddle.net/highcharts/ZQQpS/2/embedded/result/

I explored Telerik's KendoUI and its MVC wrapper charts but it looks like this feature is not available. Is it? Any help?

Thanks

Grouping by 3 columns, but showing sum of another columsn only once

Hi all,
I'm building a grid where I group my data by 3 columns, but I show the sum of another column as ClientGroupFooterTemplate. Here some code snippet
Inside data source:
.Group(gr =>
{
gr.Add(p=> p.Finality);
gr.Add(p=> p.Task);
gr.Add(p=> p.Session);
}
)
.Aggregates(aggr =>
{
aggr.Add(p => p.Duration).Sum();
})

Inside .Columns

//previous columns code

columns.Bound(c => c.Duration).Title("Duration (h)").Width(150).ClientGroupFooterTemplate("Sum: #=sum#");

//following columns code

but when grid displays the data it shows the Sum at the end of every grouping (Finality, Task and Session)
I want to diplay it only for Session, how can I accomplish that?

Date format in Kendo Grid Edit Popup

Despite my best efforts I cannot make the dates returned from the controller appear as dd/mm/yyyy in the edit popup of my kendo grid. I have [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}", ApplyFormatInEditMode = true)] above the dates in my model and have even doubled my effort by declaring the date format in the HTML Helper itself. I have tried TextBoxFor(), TextAreaFor(), DisplayFor(), and still the date appears as below. Any help would be appreciated.

TreeView Checkbox problems

Currently, your treeview checkbox demo does not match the source code included on the page. The source code indicates there should be a "Find Checked Nodes" button, but your demo doesn't have this. When I do a View Source, I see that there is an onCheck script to report what has been checked.

In contrast, in my downloaded local demo source code (I am using MVC Q2 2014 SP2), the Find Checked Nodes button exists, but it doesn't do anything. I am brand new to MVC .NET and jQuery (with some experience with WebForms), so the inconsistencies make things even harder to understand.

What I WANT to happen is to get the checked values in my HTTPPost controller method, so I can do some database work with the results, but I can't figure out how to get the user checked values there. How can I do this?

My simplified model:

public class MyModel

{

public string OtherStuff {get; set;}

public IEnumerable<TreeViewItemModel> treeData { get; set; }

}

My simplified view:

@model MyModel

<text>@Model.SomethingElse</text>

@(Html.Kendo().TreeView()

.Name("treeview-left")

.ExpandAll(true)

.Checkboxes(checkboxes => checkboxes

.Name("checkedPubIds")

.CheckChildren(true)

)

.BindTo(Model.treeData)

)

My relevant controller methods:

private MyModel GetMyModel()

{

var model = new PubTreeModel

{

OtherStuff = "Hello",

treeData = GetTreeData() // implementation omitted here

};

return model;

}

[HttpGet]

public ActionResult Index()

{

var model = GetMyModel();

return View(model);

}

[HttpPost]

public ActionResult Index(MyModel model)

{

if (ModelState.IsValid)

{

// Access Violation, because model.treeData is null. Why?

foreach (var x in model.treeData)

{

if (x.Checked)

{

// do something

}

// Have to do this or View(model) will break,

// because there is no treeData in it.

model = GetPubTreeModel(model.SelectedUserId);

return View(model);
