Filter dropdown in edit mode based on previous selected dropdown(s)

Hi

I'm using the approach found here (Editing Custom Editor) to bind some of my fields during edit mode to dropdown menus.

Everything works great but I need to know if it is possible to filter dropdowns during edit mode based on a previous selected value, which also happens to be a dropdown.

To help explain myself better, here is how the structure work:

[dropdown 1] [dropdown 2] [dropdown 3]
select * where parentId = null select * where parentId = id of dropdown 1 select * where parentId = id of dropdown

As you can see above, I will need to find a way to query the server on each change of the dropdown item to filter out the data I need to bind for the next dropdown.

I will appreciate it if anybody can point me in the right direction or perhaps to some relevant samples.

Thanks

Use DisplayTemplate default for grid cells

I have complex objects that need to be rendered in each grid, is there any way to make them render as their DisplayTemplates rather than having to manually create a javascript templates for each row.

The whole selling point of Kendo MVC was that I wouldn't have to screw around with javascript, and true, I haven't been using much javascript (which I'm familiar with) except for the workarounds for Kendo!

SCRIPT5007: Unable to get value of the property 'nextSibling': object is null or undefined

I have a combo box bound to remote data:

@(Html.Kendo().ComboBox()
.Name("cbUser")
.HtmlAttributes(new { style = "width:350px" })
.DataTextField("DisplayName")
.DataValueField("Guid")
.Filter("contains")
.AutoBind(false)
.MinLength(0)
.DataSource(source => source
.Read(read => read.Action(AdministrationController.GetUsersAction, AdministrationController.Controller))
.ServerFiltering(true))
.Events(e => e.Change("UserSelected"))
)

If I just focus this control (there are no items yet) and hit the up/down keys I get the following javascript errors:

SCRIPT5007: Unable to get value of the property 'previousSibling': object is null or undefined
kendo.all.min.js, line 14 character 15241

Custom PopUp Editor - Perform Action and Remain Open?

This is partially a Kendo Grid question and I think partially a general MVC question.

I have a Grid and I am using a custom popup editor template. Within that template I have one field (from the grid) which is for EmployeeID. While the editor window is open I want them to enter the EmployeeID and have it do a lookup and get the employee name for that ID and display it so they can make sure it is correct before they submit.

I'm not really sure how to go about doing that. Any advice or examples would be greatly appreciated.

Thanks,

Steve

Tab not displayed while loading content dynamically

Hi Telerik team !

I have an issue using tabstrip in ASP.NET MVC4.
I have a dynamic number of tabs (4 for the moment) with a dynamic content based on the tab.
I use a datasource built with JSON to generate my tabs, and the content of the tabs is a partial view (same partial view each time but filled with JSON datasource in a grid).
The funny part is that loading a tab allow me to load the other ones (previous ones) but not the next ones, ie loading the last tab allow me to see all the tabs i want in the tabstrip, but loading the first one only allow me to see the first one.
I'm using Kendo 2013.1.514, on Windows 7 64bits, and Chrome 28.0.1500.72 m
Here's my code for building the tabstrip:

01.@{

02. ViewBag.Title = "";

03. Layout = "~/Views/Shared/_AdminLayout.cshtml";

04.}

05.<div class="span9">

06. <div id="list-wrapper">

07. <div class="k-content">

08. <div id="tabStrip"></div>

09. </div>

10. </div>

11.</div>

12.

13.<script>

14. $(document).ready(function () {

15. var data = new kendo.data.DataSource({

16. type: "json",

17. transport: {

18. read: {

19. type: "POST",

20. url: "@Url.Action("RequestTabs")/",

21. dataType: "json",

22. contentType: "application/json; charset=utf-8",

23. error: function (xhr, ajaxOptions, thrownError)

24. {

25. alert("error " + xhr.responseText);

26. }

27. }

28. }

29. });

30.

31. $("#tabStrip").kendoTabStrip({

32. dataTextField: "Text",

33. dataContentUrlField: "ContentUrl",

34. dataSource: data

35. });

36. //$("#tabStrip").data("kendoTabStrip").select()

37. });

38.

</script>

Here's my code for the pages :

01.<div id="GridTD"></div>

02.

03.<script id="rowTemplate" type="text/x-kendo-template">

04. <tr>

05. <td>

06. #: ModuleName #

07. </td>

08. @foreach (AccessModel access in Model.access)

09. {

10. <text>

11. <td id="Active-#: @Html.Raw("Acc"+access.AccessID.ToString()) #">

12. </td>

13. </text>

14. }

15. </tr>

16.</script>

17.

18.<script>

19. $(document).ready(function () {

20.

21. var columnSchema = [];

22. columnSchema.push({ field: "ModulID", hidden: true });

23. columnSchema.push({ field: "ModuleName" });

24. @foreach (AccessModel access in Model.access)

25. {

26. <text>

27. columnSchema.push({ field: "@access.AccessName" });

28. </text>

29. }

30.

31. var data = new kendo.data.DataSource({

32. type: "json",

33. transport: {

34. read: {

35. type: "POST",

36. url: "@Url.Action("RequestTabGroup")/@Model.ID",

37. dataType: "json",

38. contentType: "application/json; charset=utf-8",

39. error: function (xhr, ajaxOptions, thrownError)

40. {

41. alert("error " + xhr.responseText);

42. }

43. }

44. },

45. schema: {

46. data: "TabGroup",

47. model: {

48. fields: {

49. }

50. },

51. total: function (response) {

52. return $(response.TabGroup).length;

53. }

54. },

55. pageSize: 12

56. });

57.

58. $("#GridTD").kendoGrid({

59. dataSource: data,

60. columns: columnSchema,

61. sortable: true,

62. pageable: true,

63. rowTemplate: kendo.template($("#rowTemplate").html())

64. });

65. });

66.</script>

Feel free to ask me more source code if something is missing.

PS : I'm using template to style my row, but i can't make a "border" for more visibility (like in excel). Is there something to add to the <tr> to make this change ?

Thanks in advance for your answer.

Sending values to action - the correct way

Hi,

please have a look at my forum post:
http://www.kendoui.com/forums/permalink/boGRRa6aG2OF1P8AAFTdxQ

I posted it in the wrong category. Its actually ASP.NET MVC 4! If somebody could move it to this forum, that would be great.

Post filtered grid's results back to server

Hi

How can I go about posting the grid back to my controller with the filtered results?

I basically have a filterable grid and a button which need to handle the data from the grid, but only the filtered results using the built-in filtering functions.

Thanks

Creating a custom edit form

The edit functionality of the grid is not working out for me...
I have come up with an ajax action link but would like to style it the same as the edit button without it firing the edit.

so far I have this but it produces one icon in the button and one outside of the button and there is no text, How can I recreate the edit button without it firing the default edit command of the grid?

<a class='k-button k-button-icontext' data-ajax='true' data-ajax-mode='replace' data-ajax-method='Get' data-ajax-update='\\#editorform' href='/FallsAssessment/Edit?EventID=#=EventID #' data-ajax-success='showModal'><span class='k-icon k-i-pencil'/>Edit</a>

Thanks

"The method or operation is not implemented" with 2013.1.319.340

Hi,

Just downloaded 2013.1.319.340 and am receiving the following error when using the menu:

"The method or operation is not implemented".

(StackTrace)

[NotImplementedException: The method or operation is not implemented.]

(rest omitted for brevity)

The code is as follows:

@(Html.Kendo().Menu()

.Name("mn-case")

.Items(items =>

{

items.Add().Text("Dashboard").Action("Index", "Dashboard", new { caseId = caseId, area="Case" });

}))

The route is defined as follows:

context.MapRoute("CaseIndex",

"Case/{caseId}/{controller}",

new { action = "Index"},

new RouteValueDictionary { { "httpMethod", new HttpMethodConstraint("GET") }}

);

This did not happen in previous versions and the workaround is to use Url.Action as follows:

items.Add().Text("Dashboard").Url(@Url.Action("Index", "Dashboard", new { caseId = caseId, area="Case" }));

I have many projects that use the menu and do not want to have to change them all. Is this a problem on my end or is it Kendo?

Thank you,
David Adams

Panel bar data object is null in initialization

Hello,

I'm trying to migrate a panel bar from MVC extensions to Kendo. When the Panel bar loads, I expand specific items via a initialization script.
What I find is that if I call

var panelbar = $("#PanelBar").data("kendoPanelBar");

in $(document).ready() as adviced as in

http://docs.kendoui.com/getting-started/using-kendo-with/aspnet-mvc/migration/widgets/panelbar, I get a null object.
This call however succeeds to get the correct object if called later.
Since, onLoad() is removed in Kendo, is there any other way I can initialize my Panelbar ?

Kind Regards

Achilles
