how to select an item after binding it on client side

Hi,

I am loading the dropdown on client side page load by calling the Controller action that returs JSON object. The callback function looks as below:

function

(result) {

debugger;

comboBox = $find(

"<%= comboBox.ClientID%>");

for (var i = 0; i < $(result).length; i++) {

var item = result[i];

var comboItem = new Telerik.Web.UI.RadComboBoxItem();

comboItem.set_text(item.FullDescription);

comboItem.set_value(item.PatientIdentifier);

comboBox .get_items().add(comboItem);

if (item.PatientIdentifier == patId) {

comboItem.select();

}

});

It populates the combobox except the selection. When calling select() it throws an exception in the following line:

__doPostBack(

'ctl00$PageHeadTitle$comboBox','{"Command":"Select","Index":0}')

I tried to cancel the default behavior as below:

// This cancels the default RadComboBox behavior

function itemsRequesting(sender, args) {

args.set_cancel(

true);

}

It does not select the given item. Please guide me about how to select an item after binding it on client side.

Thanks

[Solved] Change size and attributes of popup file window

I want to change the initial size of the popup window used on double click of a file and also make the window resizable. Currently the window is very small which is ok for images I guess, but I want to open pdf files etc and they are far too small for that purpose.

Thanks in advance, Steve

MOSS Rad Editor Installation

Hi there,

Q1. Does the MOSS Rad Editor installation support side by side installation? Both version 2008 Q3 and 2009 Q1 in the same MOSS farm.

Q2. We have only installed ASP.NET AJAX 3.5 to get MOSS Rad Editor work. In your installation guide ASP.NET AJAX 1.0 is required. Do we need to install both versions of ASP.NET AJAX 1.0 and 3.5?

Thanks in advance

RadComboBox not populating?

I'm trying to get the RadComboBox to work. We're using the RadControls 'Prometheus' for ASPNET Q3 2007 version: 2007.03.1314.20 from the Telerik.Web.UI.dll.; I believe this version is for AJAX.

When the page appears, the combo box appears with the text containing the first row(as expected), but it seems to be disabled. Nothing happens when clicking the drop-down arrow, nor entering text into the combobox itself.

I have tested this exact code with an older version (RadControls fro ASP.NET Q3 2007: version 2.8.3.0 RadCombobox.Net2.dll; I believe this version is NOT for AJAX.) and it works perfectly. (The only difference is the removal of a RadScriptManager which was required for the Prometheus version.)

The goal is to implement the Load On Demand functionality - similar to the example here:
http://demos.telerik.com/aspnet-ajax/ComboBox/Examples/PopulatingWithData/AutoCompleteSql/DefaultCS.aspx
but the ItemsRequested event doesn't seem to fire when using the example given here:
http://www.telerik.com/help/aspnet-ajax/combo_loadondemandoverview.html
I have attached my code. Any help would be great.
Thanks.

Exporting Grid in Console Application

I am attempting to programmatically setup and databind the Rad Grid in a Console application in order to automatically export the grid contents on a scheduled time frame to a user.

I am able to get the DataBind() call to work by creating a Page object and adding the RadControl object to the page, and successfully fill the grid with data, however the GridExporting event will not fire when calling ExportToCSV()

I do have the event setup correctly.

Is this approach possible?

Thanks,

Eric

[Solved] Sample broken?

Hi,

it looks as if this sample is broken: http://demos.telerik.com/aspnet-ajax/combobox/examples/loadondemand/adonetdataservice/defaultcs.aspx

"Open the combobox to see all item" - if I open it's empty.
So filtering (of course) has also no effect.

Tested with IE8

RadTextBox postback problem

Hi,

I implemented with RadTextBox, when it runs, I pressed "enter", it causes a post back event and it runs through all defined events of other components. I tried to set the attribute autopostback to be true unfortunately it does not help as the standard textbox of visual studio does.

Cheers,

Duy

RadWindowManager oManager Not Defined

I am using the RADMenu control (the non-AJAX one so it's kind of old now) to open a RADWindow (the AJAX one). It all works great if the RadWindowManager is on a content page, but as soon as I put it on my masterpage directly I get the Javascript error about oManager being undefined.

Is this situation not supported? How would it even be different between a content page and a masterpage?
