    I have a button. When the user clicks the button, the code behind should check on several things and if certain conditions exist, it should pop up a dialog box asking for a supervisor's password. If the password is valid, then the code behind should continue processing.

    I was able to successfully implement with a radprompt, however, when password input really needs to be masked as the user types it. So I think I need to create a separate form where I can control masking on the input textbox. I have tried what fills like a gazillion variations of javascript but can't get this to work.

    In my latest attempt, I followed the code described here:   This got me as far as the dialog form actually opening but I can't get a parameter in and I can't get the password back out.

    Here is my window definition,  inside a radwindow manager:

    <telerik:RadWindow ID="rwPassword" runat="server" Modal="True" NavigateUrl="~/UserPages/dlgPassword.aspx" Height = "500px" Width = "400px" Title="Out of Spec" Behaviors="Close, Move" Behavior="Close, Move">



    Here is the current codebehind which opens it:

    Dim script As String = "function f(){$find(""" + rwPassword.ClientID + """).show(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);"

    ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", script, True)

    The current markup of my password window looks like this. The javascript there was from an earlier attempt but I don't see why it wouldn't work with this version. After the form opens, I have to close with the X. The OK and Cancel buttons do absolutely nothing.

    I have been stuck on this for days. If anyone could help, I would be so grateful.
    Thank you.

    Hi Lisa,

    Please have a look into the sample code snippet which works fine at my end.

    MainPage ASPX:
    <telerik:RadButton ID="RadButton1" runat="server" Text="Open RadWindow" OnClick="RadButton1_Click">
    <telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableViewState="false"
            <telerik:RadWindow ID="rwPassword" runat="server" Modal="True" NavigateUrl="password.aspx"
                Height="500px" Width="400px" Title="Out of Spec" Behaviors="Close, Move" Behavior="Close, Move">
    <telerik:RadButton ID="RadButton2" runat="server" AutoPostBack="false" OnClientClicked="getdata"

    Main Page C#:
    protected void RadButton1_Click(object sender, EventArgs e)
        //opening the radwindow page
        string script = "function f(){$find(\"" + rwPassword.ClientID + "\").show(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);";
        ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", script, true);

    Main Page JavaScript:
    <script type="text/javascript">
        function loadPageVar(sVar) {
            return decodeURI( RegExp("^(?:.*[&\\?]" + encodeURI(sVar).replace(/[\.\+\*]/g, "\\$&") + "(?:\\=([^&]*))?)?.*$", "i"), "$1"));
        function getdata(sender, args) {
            //get the password from the radwindow
            var s = loadPageVar('text');

    RadWindowPage ASPX:
    <telerik:RadTextBox ID="RadTextBox1" runat="server" TextMode="Password">
    <telerik:RadButton ID="RadButton1" runat="server" Text="Submit" AutoPostBack="false"

    RadWindowPage JavaScript:
    <script type="text/javascript">
        function changepage(sender, args) {
            //accessing the radtextboxvalue
            var text = $find("<%=RadTextBox1.ClientID %>").get_value();
            //rediecting to the previous page and passing argument
   = "PassingParameter.aspx?&text=" + text;

    Let me know if you have any concern.
