I have a ClientListItem javascript prototype with several fields such as "ClientName" and "ClientID". I have a list of these objects in a viewmodel datasource called "BrokersDatasource". It is a property of a kendo observable.

In the HTML markup I declare the combobox and bind it to the datasource with the following
<input
id="viewRequest_drpBroker"
data-role="combobox"
data-text-field="ClientName"
data-value-field="ClientID"
data-bind="source: BrokersDatasource, value: InspectionRequest.BrokerID"
/>

The list is populated correctly, the datasource is bound, the proper text appears, however the ClientID is not being bound as the value. On selection of a combobox item I am expecting the ClientID to be reflected in the viewmodels InspectionRequest.BrokerID. However instead of setting the ClientID, it is setting the entire ClientListItem instance to the BrokerID. So the actual BrokerID value is something like '{ClientName: "Generic Broker", ClientID: "44"}', when in fact it should just be "44".

The issue only occurs one way. If I set the BrokerID using viewmodel.set("InspectionRequest.BrokerID", 44), it will find and toggle the correct list item and text in the widget. However when selecting from GUI/Widget it sets the BrokerID to entire instance of the object instead of just numeric value.

The bug is present in both the latest commercial release(2012.1.515) and latest internal build(2012.1.615). I have used autocomplete and dropdownlists in a similar way with no issues encountered.

Do you enjoy Google’s instant search feature?  If so, this is the tutorial for you.  Basically we want to create a widget that will update search results as you type in a text box. Google calls this “Instant”.  We can achieve this same functionality by combining the AutoComplete widget and the Grid widget.

Setup the AutoComplete control.
We need to set Suggest = false, otherwise the control will attempt to suggest a value within the search textbox.  The magic happens in our event handlers, “BenefitDataBound” and “OnOpen”.

When the AutoComplete widget is databound, we simply want to extract the JSON data from the datasource and pass it off to a method that will create and bind a Grid.

Or if you prefer to create everything using the MVC wrappers, you can do the following:



Lastly we need to prevent the AutoComplete widget from displaying any UI.  This can be handled by the OnOpen event handler.

There you have it.  Enjoy!

Hi. 

I am trying to figure out how I get only the checked children of a node, not checked grand children. 

I use this code at the moment, fires when i click on a link attached to the parent:

var tree = $("#treeview").data("kendoTreeView");
var items = $(this).closest(".k-item").find(".k-group .k-item input[type=checkbox]:checked");
                items.each(function() {
                    var getNode = $(this).closest(".k-item");
                    var item = tree.dataItem(getNode);
                    console.log(item.id);
                });
            }

This code gives me all checked children, grand children and so on, but i need only the children. I tried changing the .find() filter with .children() filter, but then items is empty.

Can anyone point me in the right direction? Your help is much much appreciated.

Hi,

I am using kendo date picker in couple of places in my application, and it is appearing differently in some places. Some places these are having shadow around them while some places these are fine.
Please see the attached file to see the appearances.

Please le me know why these are having shadow around them.

Regards,

Poonam

Edited to add - I just realized I didn't put this post in the MVC specific forum.  I'm going to post it there as well, feel free to delete this if necessary.

Greetings, I've been trying to set up a modal popup Window that contains a treeview from which a user can select a single item and then close the window.  

I basically took the code we use all over our site for modal popup windows (without errors) and then just tried putting a treeview in it.   In Firefox the error is not explicitly thrown, the tree itself renders, but anything you tried to put in the window underneath the treeview does not render at all.  In Chrome, the window renders but not the tree and no error is thrown (i.e. you get an empty window).  In IE you get an error in jQuery-1.8.2.min.js as soon as you try to open the window.  The error says "0x80020101 Microsoft JScript Runtime Error:  could not complete the operation due to error 80020101" (useful, I know).  The window never opens at all.

I created a dummy test page on my site that includes only the kendo and jQuery libraries/css/js files in the layout and removes everything not involved with housing the treeview in the window and I still get the same error.

The error occurs before calling the controller method to get the data to populate the tree (and I have another treeview that is NOT in a window using the same controller method which one works properly, and if I run in firefox it does actually call the method and populate the tree, just nothing below the tree like buttons - so I am positive the problem is not the controller method).  You can substitute any data you want if you try to repro this since the code below is data agnostic, just give it's type a property called TagName or substitute your own value of DataTextField.

If I remove the code defining the treeview and replace it with a simple "hi", I do not get the error, which proves the problem is the tree + window combination (because remember, the exact same tree works perfectly outside of the window).  

My code is below, distilled down to the absolute simplest case, still throwing the same error in IE9:
(I even got rid of the select handler and the confirm/cancel buttons just to try to get rid of the error)

The versions of jQuery & jQueryUI we include are the full downloaded library from jQuery - we have not customized them in any way.  The specific version number that we are using are ones we've had to upgrade to because of error conflicts with other between other Kendo controls and jQuery.  I suspect something similar is at play here.

If there is a specific way I need to set up the window to support this functionality please let me know, or if there is a problem with the interaction of the window + tree + jQuery that needs to be fixed can we please get a patch for it ASAP?  There are a bunch of places in our app where we'll need to have a tree in a popup window like this.

Thanks in advance, please let me know if you need anything else from me to diagnose the issue!

I'm using the following code for my transport options of a kendo grid
With the read option, Project { Id : 2 } is neatly added tot the JSON data that is created through the parametermap (just a JSON stringify return) but this is not the case with the update option, why? is this a bug?
I tried putting the adding of the project id in the parametermap but I can't seem to get that to work, any examples?

I have several DropDownLists on a page that all have AutoBind = false and set to query a remote data source.

The results shown in each DropDownList will be dependent on values chosen in the other DropDownLists, therefore in the change event I want to "reset" all the other dropdownlists, so that if they have already been bound the next time they are dropped down they will requery the remote dataSource. 

I've managed to get the other dropdownlists to requery, but at the moment they all requery straight away, whereas I want them to wait until the user drops them down. 

Is there a way to tell a DropDownList/DataSource that it should be cleared/reset, but not rebind yet, rather using the same behaviour as AutoBind=False?

Hello. I have implemented a ListView inside an expandable area of a grid row. The preview of the list inside the expandable area is working fine. The problem is when i go on the edit mode of the List and then press cancel.
After pressing the cancel button i am not allowed to expand the row anymore.  For your information, no error is thrown.

I have created a jsFiddle example that illustrates the problem.
To reproduce the behavior written above, go through the following steps:
1) Expand a row
2) Press on "Edit" button
3) Press on "Cancel" button.

After that you will notice that the row cannot be expanded again. Any suggestions ?

Thank you in advance

We are trying to set specific date returns and reload the charts. Everything is working except that when the we call the chart.refresh or chart.redraw functions, the dataItem specified in the tooltip template is returning undefined. Would appreciate any help.

function updateDateRange(timelabel) {
  var prevDateRange = timelabel.text();

  var dateRange = new Date();

  switch (prevDateRange) {
    case "7 days":
      timelabel.text("30 days");
      dateRange.setDate(dateRange.getDate() - 30);
      break;
    case "30 days":
      timelabel.text("60 days");
      dateRange.setDate(dateRange.getDate() - 60);
      break;
    case "60 days":
      timelabel.text("90 days");
      dateRange.setDate(dateRange.getDate() - 90);
      break;
    case "90 days":
      timelabel.text("7 days");
      dateRange.setDate(dateRange.getDate() - 7);
      break;
  }

  var chart = timelabel.siblings(".widgetchart").data("kendoChart");

  chart.options.categoryAxis.min = dateRange;
  /* Note: For some reason, if the min value of the categoryAxis is set to a low enough  value (in my tests, less than 10 days from the current date), it rewrites the dataItem value in the tooltip template, causing it to throw a few undefined where dataItem properties are being accessed. Modifying other properties of the kendoChart data object does not cause it to break. */
  chart.redraw();
}

Hi,

I am using struts tags eg <s:textbox> and when I try to use the kendo validators in struts it does not work and I do not want to use <input type > tags as they are not shown properly on IE for my project but kendo validation works fine on them.

Kindly show me a workaround to use the kendoValidator in struts2.0 as the whole project is made using struts tag library and Its not very difficult to change to <input type>

Please help.

Regards and thanks in advance
Nitesh
