Hello,

I have been trying to get the batch grid to work with a file upload. The aim is to update the grid with the information in the text file. Would this be a common scenario which has been tried before?

For temporary solution, I processed the uploaded file and save it in the server and render the partial view which contain
@html.Kendo().Grid()

Then, during loading of the partial view, the Read( read.Action ("Test","TestController")) is invoked and load the data from the text file.

Is there a way to set the dirty flag manually after the initial load of the grid so that I can click the save button?

Thank you,

-sk

Kendo().DropDownListFor not updating, while Html.DropDownListFor does

I have a situation, in which the Kendo().DropDownListFor isn't working as expected; I'm using a dropdown in a KendoGrid edit popup. The user is allowed to choose a user friendly value for a foreign key.

This is working:

@Html.DropDownListFor(m => m, new SelectList(ViewBag.Partners, "Id", "FriendlyName"), "Select Partner")

But this is not:

@(Html.Kendo().DropDownListFor(m => m)

.BindTo(new SelectList(ViewBag.Partners, "Id", "FriendlyName"))

.OptionLabel("Select Partner"))

In both cases, the dropdown is displayed correctly, and the initial value is correctly selected.
However, when saving, the Id field is cleared. When I look at the generated HTML markup, this is a part of it:

<ul unselectable="on" class="k-list k-reset" tabindex="-1" role="listbox" aria-hidden="true" id="PartnerId_listbox" aria-live="off" style="overflow: auto; height: auto;"><li tabindex="-1" role="option" unselectable="on" class="k-item">Select Partner</li><li tabindex="-1" role="option" unselectable="on" class="k-item">Indicia Test SFTP</li><li tabindex="-1" role="option" unselectable="on" class="k-item">Indicia Test Mail</li><li tabindex="-1" role="option" unselectable="on" class="k-item">Indicia Test FS</li><li tabindex="-1" role="option" unselectable="on" class="k-item k-state-selected k-state-focused" id="PartnerId_option_selected" aria-selected="true">Test Jesse</li></ul>

As you can see, no Id's are in the markup, which I find suspicious.

Here is how the ViewBag.Partners value is populated (in the controller):

/// <summary>

/// Populates the partners.

/// </summary>

protected void PopulatePartners()

{

ViewBag.Partners = Database.Partners.Select(pg => new { pg.Id, pg.FriendlyName }).ToArray();

}

What is going on here? Why is the normal Html.DropDownListFor working, while Kendo's version isn't?

Retaining order of elements after POST

Hi I have a list of items in a multiselect and I want them to be received in the order that the user has specified when being sent to the controller

Right now they seem to be sorted by whatever the datasource is sorted by.

Any tips?

MVC 5 Grid not showing data

Hi,

I've created a simple MVC 5 project with a Kendo grid to display a few records from a remote server. When i run the application, the kendo grid appears but displays no records.
I checked Fiddler and found no errors or circular references. Furthermore, the JSON output shows the correct data in it but its simply not displaying in the grid. Here is the grid and controller code:

<div style="width:830px;font-size:x-small; padding-top:40px;">

@(Html.Kendo().Grid<SystemsFormsMVC.Models.vMyForm>()

.Name("Grid1")

.Columns(columns=>

{

columns.Bound(o => o.Id);

columns.Bound(o => o.SystemName);

columns.Bound(o => o.FormType);

})

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(5)

.Read(read => read.Action("GetMyForms", "Home"))

)

.Pageable()

.Navigatable()

.Sortable()

.Filterable()

)

</div>

Controller:

public ActionResult GetMyForms([DataSourceRequest] DataSourceRequest request)

{

var query = _repository.GetMyForms(GetCurrentUserName());

query = query.OrderBy(s => s.RequestDate);

return Json(query, JsonRequestBehavior.AllowGet);

}

public IQueryable<vMyForm> GetMyForms(string UserName)

{

SystemsFormsDataContext db = new SystemsFormsDataContext();

IQueryable<vMyForm> query;

Int32 UserId = GetCurrentUserId(UserName);

try

{

query = (from s in db.vMyForms

where s.UserId == UserId

select s);

}

catch (Exception ex)

{

query = (from s in db.vMyForms

where s.UserId == 0

select s);

}

return query;

}

Could you please help me figure out what the issue is with the data not displaying in the grid?

Thanks, Shuja

New Export to Excel feature in version 2014.3.1119

I am reviewing the new export to Excel feature in version 2014.3.1119. This feature is really nice, but I cannot find a way to correctly export a grid with dropdownlists. The export shows the column, but include the foreign key, not the dropdownlist text. The new Export to PDF works correctly and downloads the text for the dropdownlist. Is there a way to get the Export to Excel to work correctly on dropdownlists?

Thanks for your help.

TreeView get childs with a POST

I have a treeview with remote data binding. Every time I expand a node it does a GET with the parent Id as parameter. Is it possible change the GET for a POST?

The reason to do this is for security. We either need to encrypt the parameter on the GET or change it as a POST.

Telerik.UI.for.AspNet.Mvc5

Hi,

We've just come to integrating our product which uses the Telerik.UI.for.AspNet.Mvc5 NuGet package and we get errors stating that it cannot be found. Having looked at Nuget.org, it seems that it has disappeared.

Any reason for this, or is there an alternative location that I can use? I notice a ZIP file in my Product download page. I guess I need to host that locally. THough I would like confirmation that the original NuGet repository package has disappeared - and why considering this will break a lot of builds.

Thanks

Monthly/Yearly aggregate

I would like to create sub total rows and group header rows for Monthly and Yearly totals and counts. I have a date field and a payment field. I can't see any way of doing this without creating extra columns in my data. Is there an example that works with dates that is available anywhere?

Thanks,

Larry

TreeList LoadOnDemand

I am trying to use the TreeList widget (http://demos.telerik.com/kendo-ui/treelist/index), but with a lot of data (~2000 rows). It seems to not handle this well as it tries to load all everything at once.

There is a similar TreeView widget (http://demos.telerik.com/kendo-ui/treeview/index), which allows for a configurable method called “LoadOnDemand” (http://docs.telerik.com/kendo-ui/api/javascript/ui/treeview#configuration-loadOnDemand) that allows the children for a node to be loaded when the parent is expanded, but I can't seem to find a similar function for the treelist widget.

Is there an alternative way to achieve the same functionality (loading the children on expand of their parent)?

Override default key event methods

Hi,

We're using numeric textboxes in a grid that allows for keyboard navigation. The problem is that the up/down arrows still increase and decrease the values in the textbox before the navigation event occurs. Is there a way to disable the default key events, or modify them?

Thanks,
Kevin
