Change kendoDropDownList remote dataSource

hi all,

as per title, how to make this possible?

var newDataSource=new kendo.data.DataSource({

transport : {

read : {

url : context+"/master/common/listLocationByCountry/"+data.country.id+"?marketDifferentialId="+data.id+"&locationId="+data.location.id

}

});

newDataSource.read();

var locationName = data.location.name;

var locationValue=data.location.id;

var locationDropDown = $("#locationId").data("kendoDropDownList");

locationDropDown.setOptions({ dataTextField: "name", dataValueField: "id" });

locationDropDown.setDataSource(newDataSource);

$("#locationId").val(locationValue).data("kendoDropDownList").text(locationName);

the problem is the dropdown is still access url from old datasource to pupolate.

thanks

root menu without submenu has the error "Input string was not in a correct format."

I got that error when I am building a menu based on a sqlDataSource with the following SelectCommand:
SelectCommand="SELECT '1' AS id, null as pid, 'A&SI' AS text, '' as url
UNION ALL
SELECT '2', null, 'P&P',''
UNION ALL
SELECT '3', null, 'T&E',''
UNION ALL
SELECT '4', null, 'FTR',''
">

However, it works if I add two union statements like below to the end:
SelectCommand="SELECT '1' AS id, null as pid, 'A&SI' AS text, '' as url
UNION ALL
SELECT '2', null, 'P&P',''
UNION ALL
SELECT '3', null, 'T&E',''
UNION ALL
SELECT '4', null, 'FTR',''
UNION ALL
SELECT '7', null, '',''
UNION ALL
SELECT '8', '7', '',''
">

The selectcommand eventually will be replaced by a stored procedure and I do not want to fix the problem by manipulating the procedure using dirty tricks like this.

Any ideas? Thanks!!

Context Menu item contentTemplate not showing

Windows 7 pro x64
VS2008 web page
Telerik UI for ASP.NET AJAX Q2 2014 - Bin35

In this simple page, there is a context menu with 3 items
the third item uses a content template.
Right click over the text to show the context menu.
The third item does not show up in the browser but is rendered along with an empty iframe. why?

my goal is to put some text and a textbox (html element) where the text would normally be in a radMenuItem.
something like
<content Template>part number contains: <input type="textbox" /></contentTemplate>
so that the user can right-click and click in the textbox and type something in. (I can catch the ENTER keystroke and do the post back)

Collapse all nodes when filter is empty

Hello,

I am using the control to replace a old control we made ourself and that have the same behaviour as this DropDownTree. I have suscceeded yto d pretty much everything I wanted. There is only one thing I want to do, I want all the node to collapse when the filter is empty.
I have tried several solutions, my closest one is this one, but is not working proprely. Sometimes it works, sometimes it does not :

I have attached to the DropDownTree OnClientLoad client side event this function :

function loadTreeView(sender, args) {

var dropdowntree1 = $find("<%=ddtList.ClientID%>");

var tree = dropdowntree1.get_embeddedTree();

$(".rddtFilterInput").keyup(function () {

if ($(".rddtFilterInput").val() == '')

treeCollapseAllNodes(tree);

}

I've tryed that too : $(".rddtFilterInput").on('input',function () {...}); But no success either...

I can see that it collapse the nodes but right after they are expanding again.
I also tried to cancel the OnClientNodeExpanding event when the filter is empty but no success here either...

Do you have any solutions that realize what i'm trying to do ?

Thanks

Data does not appear in grid when creating grouping in code behind page

I have an issue when trying to set up grouping in the code behind (vb.net) in that the data does not appear.
If I set up the grouping on the aspx page the records show up.
I have tried adding the datasource and databind before and after this code but I never get any records to appear.
I want to be able to dynamically turn certain grouping on or off depending on the user selection.
Can you tell me why the records are not showing up when I use the code behind page to create the grouping?

RadGrid1.MasterTableView.GroupByExpressions.Clear()
Dim ShowFacilities As CheckBox = ctlOptions.FindControl("cbShowFacilities")
If ShowFacilities.Checked Then
Dim ge1 As New Telerik.Web.UI.GridGroupByExpression
Dim gf1 As New Telerik.Web.UI.GridGroupByField
gf1.FieldName = "Facility"
gf1.HeaderValueSeparator = String.Empty
gf1.HeaderText = "Facility - "
ge1.SelectFields.Add(gf1)
RadGrid1.MasterTableView.GroupByExpressions.Add(ge1)

Dim ge2 As New Telerik.Web.UI.GridGroupByExpression
Dim gf2 As New Telerik.Web.UI.GridGroupByField
gf2.FieldName = "Name"
gf2.HeaderValueSeparator = String.Empty
gf2.HeaderText = " "
ge2.SelectFields.Add(gf2)
RadGrid1.MasterTableView.GroupByExpressions.Add(ge2)

Else
Dim ge2 As New Telerik.Web.UI.GridGroupByExpression
Dim gf2 As New Telerik.Web.UI.GridGroupByField
gf2.FieldName = "Name"
gf2.HeaderValueSeparator = String.Empty
gf2.HeaderText = " "
ge2.SelectFields.Add(gf2)
RadGrid1.MasterTableView.GroupByExpressions.Add(ge2)

End If

RadGrid1.DataSource = MyDataSource
RadGrid1.DataBind

Print from RadWindow Titlebar IE11

Had the following example working fine to print contents of a Radwindow from the title bar: http://www.telerik.com/support/kb/aspnet-ajax/window/details/adding-a-custom-button-to-radwindow-titlebar

However now using IE11 it prints the entire page behind the window as well.
In Firefox works fine and only prints the contents of the Radwindow.

Would appreciate and any.

Thanks

Attempt at Filtering FileExplorer

Trying to limit the results that are returned to a FileExplorer and it works sporadically and quite possibly we are missing something. If a file exists for a Credit Union it will display as it should however if there isn't one found it will return all the records in that folder (which we do not want). After it shows all the files if I click the refresh button within the FileExplorer it will then show there are no results. There is only two possible outcomes:

if a file exists for that credit union, show the file
if does not exist, show no files
