How to allow user to check only one item?

Hi,

I have two RadListBoxes:

<telerik:RadListBox ID="AllAreas" runat="server" AllowTransfer="True" TransferToID="SelectedAreas"

Height="135px" Width="250px" CheckBoxes="true" OnClientTransferred="OnAreaTransferred"

/>

<telerik:RadListBox ID="SelectedAreas" runat="server" Height="125px" Width="220px" OnClientTransferred="OnAreaTransferred" OnClientItemChecked="OnDefaultAreaChecked" CheckBoxes="true" />

I would like to have only one item checked in the list on the right. To achieve it, I'm using following javascript functions:

function OnAreaTransferred(sender, e) {

var items = e.get_items();

items.forEach(function (it) {

it.uncheck();});

}

function OnDefaultAreaChecked(sender, eventArgs) {

var item = eventArgs.get_item();

var value = item.get_value();

var checked = item.get_checked();

var listBox = item.get_listBox();

if (checked)

{

var items = listBox.get_items();

items.forEach(function (it) {

it.uncheck(); });

}

item.set_checked(checked);

}

Generally it works - but there are some strange issues:
1. When I check any item on the left list and then I transfer it - it's still checked, even though uncheck function was called on it. Firebug shows that _checkBoxElement's "checked" property is set to false (before transferring it was set to true), so I think the "checked" property has been changed, but it's still shown as checked.
2. Then on the right list I can select many items (even though unchecked function is called every time).

Does anyone know how to solve that problem?

Thank you in advance.

How to get the bound entity of editing record in UpdateCommand event

How to get the bound entity of editing record in UpdateCommand event? For example, I bound a List<Customer> to a RadGrid, when I clicking save button to fire the RadGridFunction_UpdateCommand event, I have no way to get the Customer entity of editing record. Because I don't want to retrieve the record based on current primary key from DB, I only want to get from bound source.

Fixed Row height with vertically centered text

Hi,
I'm currently evaluating your Grid component.
One thing I could not do is center my text horizontally in a cell and preserve the cell's fixed height.
I do not want my cell to change its size according to the text (which again , should be vertically align to middle).
The text should be cut when its overfloaing over the cell height.

How Can I achieve that ?

Thx
Sagi
