Hi,

I've just upgraded to the version 2018.2.620. I noticed that window.title no longer displays special characters correctly. For example:

In previous version, setting the title to finnish: "Viesti Phoenixistä" rendered correctly "Viesti Phoenixistä". Now the translation of &#228 character does not work anymore.

Are there any solutions to this?

Thanks and regards,
Viktor

I have a popup editor configured on a grid.  In the editor template, I have a dropdownfor with a Read action.  I need to pass the model value to the read action but it is not recognized.  Can you help?

Here is the editor template:

Hi,

in my MVC-App I use <authentication mode="Windows" /> and <identity impersonate="true"/> inside web.config which means the current WindowsIdentity is delivered through IIS to SQL-Server. Normally I use the async/await pattern in my code and thus use ToDataSourceResultAsync(...) to get my filtered/sorted/paged results async. When doing so I run into an error. The call from App -> IIS -> SQL-Server is now under the normal "IIS APPPOOL\DefaultAppPool" account which is not a valid SQL-Server user and so the connection is refused. When using the normal ToDataSourceResult(...) call everything works perfect.

The reason for this is the usage of "Task.Factory.StartNew(...)" inside QueryableExtensions.cs. Whenever you use "Task.Factory.StartNew(...)" the impersonation is reset to the default value and is NOT using the identity used inside the MVC-App. Here is a little example (just place the code inside a normal Controller Action):

As a result you get:
Line 1: "App is running as: myDomain\myUser"
Line 4: "New Task is running as: IIS APPPOOL\DefaultAppPool"

At least you should warn in your documentation that this could happen or think about a better solution for implementing "ToDataSourceResultAsync(...)". In my opinion my scenario is not so seldom in the enterprise world so giving a warning should be a good idea.

Heiko

Is there currently a way to use DropDownList that would allow a USER to delete an item?  We are creating a facility of saved searches and we'd love to be able to allow the user to be able to click an 'X' in a dropdown to trigger a delete of the item from the list (and ultimately the database) as seen in the attached screen shot.

We are using Telerik Rad-editor (Version: 2017.2.503.40) in our application. The Rad-editor control which we use looks like the sample you provided in "Save in database" link.
We are facing 1 issue while uploading image through Image Manager control. If we upload an image then we face 1 console error. Below is the description for the error.
ScriptResource.axd?d=WumqVucm-BTOpradDSIl6FwWq2Nf8yJ7sqq9-igzn7fhpcm7LMUuXAF__xzJt_PP7G8atwaBX_21lH9wtho_Q-JsnyL97IPmZiErbgIsKQvtmeYlHiL_GqtD3HsMVT9KS6u1-fBfjgRuY07t3m9OjNcjVdzCqYRpX7UHxymyD6WPAuy90&t=ffffffffad4b7194:5 Uncaught Error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
Can you please provide us the solution/your suggestions please?

Thanks in advance.

Hello.

I have a dropdownlist for Contact Name in a kendo grid as shown in the attachment.

When I click on the Manage Contacts button, I get a pop up which has a grid where I insert contacts.

After inserting/updating contacts and closing the popup, the Contact Name dropdownlist should display the new contacts which have just been inserted when I click on Edit for that particular row.

But this not happening. 

The code for the Contact Name editor template is as follows:

@(Html.Kendo().DropDownList()
.Name("ContactName")
.ValuePrimitive(true)
.DataValueField("ContactName")
.DataTextField("ContactName")
.OptionLabel(" ")
.DataSource(source =>
{
    source.Read(read =>
    {
        read.Action("GetVendorContacts", "VendorCont")
        .Data("filterContactName");
    })
    .ServerFiltering(true);
})
    //.AutoBind(false)
    .CascadeFrom("Vendor")
)

Is there a way to refresh the dropdown list when I click on the Edit button on the row or when I click on the dropdown list to select contacts?

I have tried to refresh the dropdownlist using the BeforeEdit and Save events, but it did not work.

This is very urgent and any help will be greatly appreciated.

Thanks and Regards

Hi,

I have a detail template in a grid. In the last column I want to have a dropdown menu based on a condition. In another (regular) grid I did this:

columns.Template(@<text></text>).ClientTemplate(@"<div class='dropdown'>
                                                            <a data-toggle='dropdown' class='primarycolor' href=''><i class='fa fa-ellipsis-v fa-2x'></i></a>
                                                            <ul class='dropdown-menu dm-icon pull-right'>"
+ "# if (ShowEditLink) { # <li><a class='k-button-icontext editReg' href='#=EditLink#' data-rid='#=Id#'>" + translator.Translate("EDIT_REGISTRATION") + "</a></li> # } #"
+ "</ul></div>").HtmlAttributes(new { @class = "dropdown-gridcell" }).Width(20);

Now I know that in the child/detail context I have to escape template expression with "\\#=fieldName\\#. Found here: https://demos.telerik.com/aspnet-mvc/grid/detailtemplate

What I'm trying is this:

columns.Template(@<text></text>).ClientTemplate(@"<div class='dropdown'>" +
  "<a data-toggle='dropdown' class='primarycolor' href=''><i class='fa fa-ellipsis-v fa-2x'></i></a>" +
  "<ul class='dropdown-menu dm-icon pull-right'>" +
"# if (booleanProperty) { # <li><a class='k-button-icontext' href='' data-spid='#=Id#'>" + translator.Translate("CANCEL") + "</a></li> # } #" +
"</ul></div>").HtmlAttributes(new  {  @class = "dropdown-gridcell"  }).Width(20);

where "booleanProperty" is a property of the viewModel in the child grid. This doesn't work because it doesn't recognize "booleanProperty" since it thinks it is in the viewModel of the parent grid. I have looked at the following posts:

https://www.telerik.com/forums/nested-detail-grid-clienttemplate-conditional-binding-expression-error

https://docs.telerik.com/aspnet-mvc/helpers/grid/faq#how-to-display-checkboxes-in-ajax-bound-grids

and tried this as well:

columns.Template(@<text></text>).ClientTemplate("\\#=showLink(booleanPropoerty, Id)\\#").Title("").HtmlAttributes(new  {  @class = "dropdown-gridcell"  }).Width(20);

function showLink(booleanProperty, id) {

var returnValue = "<div class='dropdown'><a data-toggle='dropdown' class='primarycolor' href=''><i class='fa fa-ellipsis-v fa-2x'></i></a><ul class='dropdown-menu dm-icon pull-right'>";

if (booleanProperty) {
return "<li><a class='k-button-icontext' href='' data-spid='" + id + "'>" + $('#stringValue').val() + "</a></li>";
}

returnValue += "</li></div>";

return returnValue;
}

This way I get returned a value but the required javascript for the dropdown list doesn't work.

Is there a solution for this?

Thank you,

Jokull

Grid data source is as follow:

public class Customer

{

    public string customer_id { get; set; } = "";

    public string customer_name { get; set; } = "";

    public List<Order> Orders { get; set; } = "";

    public List<Delivery> Delivery{ get; set; } = "";

}

public class Order

{

    public string order_id { get; set; } = "";

}

public class Delivery
{
    public string delivery_id { get; set; } = "";
}

My design:

Master grid will present Customer record(List<Customer>), and when I click edit button, it will pop up a edit template

and edit template will include Customer's data and two sub grids(Order, Delivery). 

My question is I know if I want to get string, it would be "#=customer_id#" but I don't know if I want to get List -- Order and Delivery -- to bind sub grids data source, how can I do.

Does anyone help me?
