Hi,

This is what my current kendo grid looks like. The scenario involves a sql table with the aim of displaying the contents of that table and providing the functionality to insert rows containing user entered data. Currently, I am providing that functionality with the toolbar kendo provides. I have a helper class in my controller which I am using to take the data from the client and place it in the action method. You can see the AdditionalData function which I have placed in my view and the onSave event below it. Those two are related to the helper class in the controller and I am using them to get the KendoGrid data back to my controller. I am not confident that this is the cleanest way to perform all of this, and any suggestions on that front are welcome. 

However, my functionality is present in the current solution I have. I just dont understand why its not giving me errors when a user tries to add two rows at the same time. When the user clicks the add row button twice, it spawns two empty rows in the grid. If they go down and put data into both rows and then click save, both rows will be conveniently inserted into my database without crashing anything. How is this possible? The eventObject in the onSave event will be assigned twice and overwritten once. Yet the additionalData function will properly be called twice with distinct values of the eventObject each time. 

Can anyone walk me through this code so that I can learn a little more? I want to know why additionalData doesnt get called twice with whatever value is last written to the eventObject variable. Will it continue to perform properly no matter how many empty rows are created with a single click of the save button? Or will it break at some limit or on some network conditions? I suspect there is a race condition. Lets talk about that.

And can anyone tell me how to disable the addRow Button in the toolbar? It would be great if the user could only click this once per click of the save button. So that they can only insert one row at a time. And can anyone tell me how to create a custom toolbar button that is basically a wrapper around the pre-defined toolbar buttons? Or how can I recreate the create toolbar button such that all of the interesting things that it does for me are exposed in my source code, so that I may properly fiddle with it? I would really like to be able to crack open the create toolbar button and see all of the things going on inside of it so that I can better understand the grid and so I can better devise custom solutions. I like having the knowledge of custom solutions in my back pocket because it means less time browsing the forums for out of the box solutions.

Thank you. Let me know if I can clarify anything.

Hi,

I use filtering on kendo grid in row mode. This works fine, except one detail. I want to have the list sorted, not in that order you can see in the attached screen. I've noticed that if I changed the sort option to "Sort(sort => sort.Add("ClientName")", the autocomplete would get the items alphabetically. But what about another fields, where I also want to have the right order. And of course I don't want to change the global order.

I will be grateful for your help

Hi,

I have a datepicker on a page which was working perfectly until yesterday. Suddenly it stopped showing existing dates in Chrome. if I select new date from the picker it works fine. I get a javascript error in the browser. I have posted similar questions with javascript error couple of years back. http://www.telerik.com/forums/date-format-error-with-date-picker 

It was resolved at that time using the Format.

Now as per the suggestion in the above link, i have change the code like this

But still no use. I still don't see the dates.

The following dropdownlist works fine:

    @(Html.Kendo().DropDownList()
            .Name("TrunkDepotsList")
            .HtmlAttributes(new { style = "width: 70px;" })
            .DataTextField("DepotNumber")
            .DataValueField("DepotID")
            .BindTo(Model.DepotList)
            .SelectedIndex(Model.DepotIndex)
    )

However - when I add an event handler, it turns into a textbox:

    @(Html.Kendo().DropDownList()
            .Name("TrunkDepotsList")
            .HtmlAttributes(new { style = "width: 70px;" })
            .DataTextField("DepotNumber")
            .DataValueField("DepotID")
            .BindTo(Model.DepotList)
            .SelectedIndex(Model.DepotIndex)
            .Events(e =>
            {
                e.Change("refreshTrunkSummaryPage");
            })
    )

For reference, here's my event handler script:

function refreshTrunkSummaryPage() {
        alert('refresh running');

        ...etc

}

The view and the controller do not seem to work together.  The view is calling a controller action that does not exist, the controller action that does exist is not returning any data.

Or if I'm wrong, I'll humbly accept corrections :-)

I'm trying to use the Telerik MVC TreeView control with the kendo.data.HierarchicalDataSource control and local data.

In samples for the Kendo Treeview, they point to the Javascript datasource like this:

dataSource: homogeneous

What syntax do I use in the fluent MVC TreeView to reference data that's held in a JavaScript variable?

Showing my hierarchical data below.

Thanks,

I have tabstrip that is displaying a partial from a different controller/view area, but I cant get the post of the partial in the tabstrip to post back to the different controller

the View that the tab is in.

~/Areas/Secure/Views/Company/companyStaff.cshtml

display a view assocated to a different controller

tabstrip.Add().Text("Create Contact")
                  .Selected(false)
                  .Content(Html.Partial("~/Areas/Secure/Views/Contact/_ContactManagement.cshtml",  new WebSite.Library.Models.Contact() , new ViewDataDictionary { { "Id", "0" } }).ToHtmlString());

How can I get the partial in the tab to post back to its own controller post method

Hi,

I am using the Pdf export to print a grid. In the page header on each page I would like to have content from the model (or the ViewBag or some other way), in any case data that I can set in the method in the controller when I load the ViewModel for the page. I have found a lot of info about the page headers, but the page number is the only variable data I have seen.

I would like to show something like "Inventory as of Dec 3rd, report printed March 21st", so not only page number and today's date but other stuff too.

Is this possible and if so, can someone please point me in the right direction for info on this?

Best regards,

Henrik

How do i get the value of a Kendo Date Picker by class name. The reason being is because im using the name and id attributes for something else. As you can see below the class attribute is dynamic. Every other time ive selected a Kendo Date Picker, i've always used the ID attribute. Is it possible to select by class attribute?

Greetings all,

I am attempting to have the same select list display on one page via MVC Display Templates. So far I've only been able to get one of the select lists to display at a time. Is this functionality not allowed. See my code example below:

The first one works. The second one does not. Is there a way to get this to work.
