I have a kendo treeview and a kendo grid on a page working nicely - when I click on a row in the grid i can drag the row over to the treeview and drop it and this works great.

I want to be able to click on a treeview node and show the products for the selected category within the grid, need some advice.

I have a kendo grid marked as follows:-

viewModel = kendo.observable({ gridSource: productdata });

script>

                var viewModel = null;

                $(document).ready(function() {
                   var treeview;

                    $("#vertical").kendoSplitter({
                        orientation: "vertical",
                        panes: [
                            { collapsible: true, size: "50%" },
                            { collapsible: true, size: "50%" }
                        ]
                    });

                    $("#horizontal").kendoSplitter({
                        panes: [
                            { collapsible: true, size: "35%" },
                            { collapsible: true, size: "65%" }
                        ]
                    });

                    treeview = $("#treeview").kendoTreeView({
                        template: kendo.template($("#treeview-template").html()),
                        dragAndDrop: false,
                        dataSource: [@(Html.Raw(Model.Json))],
                        select: onSelect
                    }).data("kendoTreeView");
                   
                    var productdata = @(Html.Raw(Model.JsonProducts));
                   
                   viewModel = kendo.observable({
                        gridSource: productdata
                   });
                  
                   
                     $("#grid").kendoGrid({

PROJECT DESCRIPTION 
I'm trying add a grid column with a Razor ActionLink to pass two parameters to a controller action and display the record details in a new view.  The Grid loads the data, but my "view" link does not show up in the Grid.

This works with the MVC3 Razor WebGrid, but I cannot get it to work with the Kendo Grid. 

Here is my Grid layout:
@(Html.Kendo().Grid(Model)            //The grid will be bound to the Model which is the Products table
          .Name("ApplicationPersonal") //The name of the grid is mandatory. It specifies the "id" attribute of the widget.
      .Columns(columns =>
      {
          columns.Bound(p => p.Id);   //Create a column bound to the "ProductID" property
          columns.Bound(p => p.LastName).Title("Last");   //Create a column bound to the "ProductID" property
          columns.Bound(p => p.FirstName).Title("First"); //Create a column bound to the "ProductName" property
          columns.Bound(p => p.appid).Title("APP ID");   //Create a column bound to the "UnitPrice" property
          columns.Bound(p => p.Email).Title("Email");//Create a column bound to the "UnitsInStock" property
          columns.Bound(p => p.HomePhone).Title("Phone");//Create a column bound to the "UnitsInStock" property     
          columns.Bound(p => p.DOB).Title("DOB");//Create a column bound to the "UnitsInStock" property   
          columns.Template(p =>
       {
        
           @Html.ActionLink("view", "ViewApplicant", "Admin", null, null, null, null, new { appid = p.appid, uid = p.Id });
           
       });
              
      })
                     
)

Thanks.

So, on the KendoEditor there is a Tooltip field. as the title states, this field only populates the Alt attribute. This only works as a tooltip in IE <= 7. It should be populating the Title attribute (or, perhaps both for compatibility) or be renamed to match what it actually does.

The issue is simple.  Without uncommenting the code that you will notice in the fiddle, binding to a viewmodel (kendo.observable) that contains a kendo.data.DataSource simply fails.  

http://jsfiddle.net/dotBomb/PMXWU/

Why?

Form binding clearly doesn't work the same way as kendoGrid binding, which I have working using a kendo.data.DataSource.  Seriously frustrating.  Not to mention when I wire this up to a transport with URLs, trying to sync the datasource via the sync() method, after editing data, fails miserably.  

Note: the collective opinion on the kendo web ui forums is that anything other than the simplest of scenarios usually fails.  I share this opinion.

Is there a way to zoom the bubbles on mouse over and shrink back to original size when the mouse goes away. 
Thanks.

I want the calendar to be "view only" (bound with MVVM)

Is there a way to perhaps disable it?  disabled="disabled" doesnt do anything

I'd like to have a datetimepicker that displays the date and time by default but only displays the date if the time is midnight. It should update the format when the value is changed. I can format the value when the datetimepicker is created to one or the other format, but if the time changes, I can't seem to update the picker's format. Any ideas on how to do this?

I am looking to have a validation message only be populated when needed. So I have an observable object with 3 fields: Value, IsValid, and Message. IsValid is dependent on Value, and Message is dependent on IsValid.

http://jsfiddle.net/GExfL/

It doesn't appear that this is allowed, but is there an easy way to design the VM to get something similar?

The closest I've come up with is a utility method that is shared by both IsValid and Message (http://jsfiddle.net/GExfL/1/), but it seems a little verbose.

Hello,

I need to get the minimum size of a given pane in the splitter. I see the following behavior...

When I call splitter.min(pane) it enters the following method in kendo.all.js:



In this case, propertyName is 'min', however, in the paneConfig the property is called 'minSize', and therefore this returns undefined.

When doing server-side paging, I am receiving results from the query string that are confusing.
The documentation for the web control grids server-side paging does not list all of the items that show up in the query string.

For instance there are keys that appear with nested filters:

filter[filters][0][filters][1][field]

and some that are not nested:

filter[filters][1][field]

There is a logical on the first level, that shows up regardless: filter[logic]
but there are also logicals that show up on other levels.

Sometimes the first columns sorting is on the first level, sometimes on the second level of nesting.

1.Is there any documentation available, that describes what the filters query string structure represents, so we can parse it and make SQL statements accordingly?
 http://docs.kendoui.com/api/framework/datasource#serverfiltering  is all I have found so far, and it is not complete.

2. If there is not documentation available, has anyone successfully parsed this data in such a way that works for all cases of multiple columns, some with one filter, two filters, and zero filters?

3. The same filters give different results, if the operator in the first column never gains focus (if you leave it on and, but enter criteria for second filter on first column). Can we assume this is a bug with the control, and can we assume this is only for the first column?

Thank you


***Update***:
 I parsed based on recurring pattern which is assuming #3 above is a special case and seems to be working ok. For anyone else trying to parse serverside filters for the grid control you can assume that all but the first column are in format:

one filter on a column: filter[filters][X][field] where X is column #
two filters on a column: filter[filters][X][filters][Y][field] where X is col # and Y is filter #

for first column see #3 above, you can make special case for that one in your parser.

Even though i got it working for me, I am still interested to see the documentation when it is updated, thanks!
