Hi

I use a RadComboBox with checkboxe that I hanle its event with javasript.

In server-side we need to set visibility of its items based on user search, then with javascript process them.

combo.get_items()   ::   in client-side return only those Items that are visible.

what should I do for it?

thanks.

Hello Fatima,

You can try hiding a RadComboBoxItem by setting its Visible property to false.
Such item will not be included in RadComboBox items collection at client-side.
<script type="text/javascript">
    function OnClientLoad(sender) {
 
        var itemsTexts="RadComboBox items are: ";
        var items = sender.get_items();
        for (i = 0; i < items.get_count(); i++)
        {
            itemsTexts += items.getItem(i).get_text() + ", ";
        }
        alert(itemsTexts);
    }
</script>
 
<telerik:RadComboBox ID="RadComboBox2" runat="server"
CheckBoxes="true" EnableCheckAllItemsCheckBox="true"  
OnClientLoad="OnClientLoad"
AutoPostBack="true">
    <Items>
        <telerik:RadComboBoxItem Text="Arts" />
        <telerik:RadComboBoxItem Text="Biographies" />
        <telerik:RadComboBoxItem Text="Children's Books" />
        <telerik:RadComboBoxItem Text="Computers" />
  
    </Items>
</telerik:RadComboBox>

All the best,

Hi Fatima,

When setting the Visible property to "false", the item is not rendered on page, and you will not able to access it from client side 
One suggestion is that you can set the style display to false as follows.

C#:
RadComboBox1.Items.FirstOrDefault().CssClass = "hidden";

CSS:
<style type="text/css">
 .hidden
 {
   display:none !important;
 }
</style>

Thanks,
Princy.
