    I have a radtextbox that I want to utilize the OnTextchange event.

    No matter what I input into the text box I immediately get "JavaScript runtime error: Unterminated string constant".

    Has anyone else seen this? Nothing too complex here.

    Inside my aspx

    <telerik:RadTextBox ID="formLocZip" runat="server" EmptyMessage="Zip" MaxLength="7" OnTextChanged="formLocZip_TextChanged" AutoPostBack="true">


    Inside my code behind :

    Protected Sub formAddLocZip_TextChanged(ByVal sender As Object, ByVal e As EventArgs) Handles formAddLocZip.TextChanged

    Unfortunately I couldn't replicate the issue at my end. Please have a look into the sample code snippet which works fine at my end. Please provide your full code for further help.

    <telerik:RadTextBox ID="RadTextBox1" runat="server" AutoPostBack="true" EmptyMessage="Zip"
        MaxLength="7" OnTextChanged="RadTextBox1_TextChanged">

    protected void RadTextBox1_TextChanged(object sender, EventArgs e)
        string text = RadTextBox1.Text;

    look at this post http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/unterminated-string-constant-error-when-calling-rad-alert.aspx it seems to address the same problem.
