    While using a RadTextBox, if a user has a very large amount to text, the text box hags the browser and maxes out the processor.


    Copy and Paste text from this file:


    Expanded File Size: 222 KB (228,152 bytes)
    218, 183 characters with spaces.
    7,201 lines
    10, 753 words.

    Skin Setting:
    <telerik:RadTextBox runat="server" Skin="Office2007" Width="400px"

    <telerik:RadTextBox Width="600px" Height="450px" runat="server" ID="txtFormatTemplateContent"
    ReadOnly="False" TextMode="multiLine" Text='<%# Bind("xslContent") %>' style="position: relative" ></telerik:RadTextBox></td>

    //Added asp.net textbox to see if it had any performance issues and it did not.
    <asp:TextBox BackColor="green" ID="txtFormatTemplateContent2"   Width="600px" Height="450px" runat="server" ReadOnly="false" TextMode="multiLine"
                                                style="position: relative" Text='<%# Bind("xslContent") %>'></asp:TextBox>

    Hi Josh,

    Generally it is not recommended to use the RadTextBox with such amounts of text as it was not designed for that purpose. I can suggest you to use the RadEditor as an alternative which was built to handle such scenarios.
