RadComboBox Issue with CheckBoxes and Filter enabled

[Subodh Gupta]

Hello All,
I whould like to share with u some trouble with using RadComboBox with CheckBoxes and Filter enabled. The problem is that after uncheck all items Combobox still show one item as checked. Version 
Here is my code:

<tr>
    <td class="adminTitle">Status</td>
    <td class="adminData">
        <telerik:RadComboBox EmptyMessage="Select Status" ID="ddlStatus" EnableCheckAllItemsCheckBox="true" Filter="Contains"
            CheckBoxes="true" runat="server" Width="298px" ToolTip="Select Status" />
    </td>
</tr>

Bind:

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
         ddlStatus.SetEnumDataSource<WfApprovalStatus>(exceptOrders.Cast<int>().ToList());
    }
}

Error appear only when I check ONE item. 
Steps to reproduce:
1. Open page
2. Check only ONE item in combobox
3. Click in empty space of page (this will close combobox window)
4. Try to uncheck item
5. One more time in empty space
6. You will see that looks like item still left checked but if u open combo box you will see that is not. If u try to send form to server 1 item will be checked

If you remove using filter all works good.

Hi Subodh Gupta,

As a work around please try the following code snippet to achieve your scenario.

ASPX:

<telerik:RadComboBox EmptyMessage="Select Status" ID="ddlStatus" EnableCheckAllItemsCheckBox="true" Filter="Contains" CheckBoxes="true" runat="server" Width="298px" OnClientItemChecking="Uncheck" ToolTip="Select Status" />

JavaScript:

<script type="text/javascript">
    function Uncheck(sender, args) {
        if (args.get_item().get_checked() == true)
            sender.clearSelection();
    }
</script>

Thanks,
Shinu.

Hello, 

Telerik said that checkboxes + filter is not supported but for me works perfectly if I add this propperty to radcombobox:

AllowCustomText = "true"
