[Solved] How to show/hide button based on value.

I have a Ajax Bound Grid with this column which works:

columns.Bound(c => c.Id).Title("")

.ClientTemplate(@Html.ActionLink("Download", "DownloadReport?Id=#=Id#")

.ToHtmlString());

How do I modify this to show/hide the URL based on c.IsReportAvailable?

Custom callback and Error Handling for Destroy in ImageBrowser

Hi Team,

I am using ImageBrowser as a part of editor widget in my screen . I need to delete an image only if it is not used by other resources. I wired the destroy to an action that checks whether its in use or not. If its in use I would return a message saying it could not be deleted .I got stuck on how to return this message to destroy and stop it from deleting the image from the library.
As the documentation says the configuration values will be sent to jquery.Ajax() function I tried using the success and error functions in the destroy configuration but could not handle the request. It always shows up as undefined.This is how I configured my imagebrowser.

01.imageBrowser: {

02. path: "/BroadcastType/",

03. transport: {

04. read: {

05. url: function () { $(".k-breadcrumbs.k-textbox").css('display', 'none'); return "../ImageBrowser/Read" },

06. type: "POST"

07. },

08. destroy: {

09. url: "../ImageBrowser/Destroy",

10. type: "POST" ,

11. success:function(){},

12. error:function(){}

13. },

14. thumbnailUrl: "../ImageBrowser/Thumbnail",

15. uploadUrl: "../ImageBrowser/Upload",

16. imageUrl: "../ImageBrowser/Image?name={0}"

17. }

18. }

In short,
How to stop image from being destroyed from the library until I get a response from backend?
How to handle any errors while backend execution?
Can we override the callback functions in the destroy configuration or should we deal with them at the transport level?

Any pointer to the right direction will be appreciated .

Thanks,
Ramoji.

Restriction of recurring events

Hello again!

The restriction works really well for drag & drop, but I'm having troubles with preventing recurring events to overlap. I can do this serverside, but that's not really the friendly way. Anyone got any tips?

[Solved] Set selectedvalue combobox

I'm using a combobox to create a searchable list of employees from where the user needs to select one.
If there is a false name entered they should get a warning (which already works) and the first person in the list needs to be selected. I Was trying to do that like this:

<div class="editor-field edit-project">

(Html.Kendo().ComboBox()

.Name("PersonId")

.HtmlAttributes(new { @class = "input-project" })

.DataTextField("Fullname").DataValueField("Id")

.DataSource(source => { source.Read(read => { read.Action("GetPeople", "Project"); }); })

.MinLength(3)

.Filter("contains")

.Events(ev => ev.Change("checkcombobox")))

</div>

And in javascript i'm doing this:

function checkcombobox(e)

{

if (this.value() && this.selectedIndex == -1) {

alert('Gelieve een geldige persoon te selecteren');

var cbx = $("#PersonId").data("kendoComboBox").Selected(0);

}

Could anyone help?

Thanks in advance

[Solved] scheduler binding/ajax issues

I'm attempting to use a custom editor template in a kendo scheduler but have 2 issues.

1. I have a mutliselect in the editor template, and am unable to get the selected options to bind and be posted to the server.
2. My ajax requests are wonky.
2a. What I'm seeing is when i click save it fires the datasource.create method multiple times (sometimes twice sometimes 3 times) and posts the same data to the server.
2b. When i attempt to delete an event the datasource.create endpoint is hit and not the datasource.destroy method.

I've attached a solution with an example. I've neven used these custom editor templates before so i think its likely im not binding it properly.

Thanks,
Chris
