RadTextBox display delay inside RadPanelBar

[ISB-developer]

Hello,

We used the property RadTextBox control TextMode = "Multiline" within <ItemTemplate> </ telerik: RadPanelItem>, and there is a delay between when the user types and what is displayed in RadTextBox. Property without the property TextMode = "Multiline" is not delayed. You can use the following code:

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">
            <telerik:RadPanelBar runat="server" ID="RadPanelBar1" Width="567px"
                Skin="Office2007">
                <Items>
                    <telerik:RadPanelItem Expanded="True" Text="Date generale" runat="server">
                        <Items>
                            <telerik:RadPanelItem Value="AccountInformation" runat="server" Expanded="true" >
                                <ItemTemplate>
                               <table  width="500px" border="0">

Hello,

I would like to inform you that Telerik has implemented a fix for that issue in their latest internal build. Check the following link Q2 2011 (version 2011.2.712) which mentions about the issue (RadTextBox does not work as expected in scenarios where TextMode="MultiLine") has been fixed.So try upgrading to the latest version Updating RadControls for ASP.NET AJAX to another version or license to achieve your requirement.

Thanks,
Princy.
