I am calling the RadAlert function in my code behind when a user clicks on the "Login" button. This is a very simple page with very simple functionality and I am following the examples to a tee, but still nothing. I am thinking it is because I am calling the function within a catch block when the login is unsuccessful, meaning that I am trying to display the window when the execution isn't finished. Can someone help me with this as I am stumped as to how best to proceed? My HTML and C# code is below:

<form runat="server" id="frmLogin">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>

<telerik:RadWindowManager ID="LoginWindowManager" runat="server" EnableShadow="true" Skin="Telerik" />

<div class="loginDiv">

<asp:Image ID="ivxLogo" AlternateText="iVidix Logo" ImageUrl="./img/ividix_logo.jpg" Height="150px"

Width="110px" runat="server" />

<tr>

<td>UserName:</td>

<td>

<telerik:RadTextBox ID="txtUserName" runat="server" Width="150px" TabIndex="0" Skin="Vista" />

</td>

</tr>

<tr>

<td>Password:</td>

<td>

<telerik:RadTextBox ID="txtPassword" runat="server" Width="150px" TabIndex="1"

TextMode="Password" Skin="Vista">

</telerik:RadTextBox></td>

</tr>

<tr>

<td>Institution:</td>

<td>

<telerik:RadComboBox ID="ddlInstitutions" runat="server" DataSourceID="srcInstitutions"

DataTextField="Name" DataValueField="InstID" TabIndex="2" Skin="Vista" AllowCustomText="True">

</telerik:RadComboBox>

</td>

</tr>

<tr>

<td colspan="2" align="right"><asp:Button ID="btnSubmit" runat="server"

Text="Login" onclick="btnSubmit_Click" TabIndex="3"/></td>

</tr>

</table>

</div>

</form>

try

{

String encryptPwd = CryptoHelper.Encrypt(password);

//log.Debug("Encrypted version of the password: " + password + " is " + encryptPwd);

userSession = SessionManager.CreateSession(userName, encryptPwd, instID);

}

catch (IvidixException ex)

{

String ErrorMessage = "UserName and/or Password in combination with the Institution were not valid. Please try again.\n";

ErrorMessage = ErrorMessage + "Specifically, " + (String) ex.LocalMessages[0] + "\n";

ErrorMessage = ErrorMessage + "Please contact Ividix Support if you feel that this error is incorrect.";

log.Error("UserDetail Session was not created properly and therefore not stored within the HttpSession.");

log.Debug("End btnSubmit_Click");

LoginWindowManager.RadAlert(ErrorMessage, 350, 200, "Error", "");

return;

}

Hi Brian,

I examined your code and I noticed that you have an unescaped "\" sign in it - please, note, that this is general JavaScript knowledge and it will break any other javascript, not only radalert (the server RadAlert method is actually a server wrapper for a js radalert method).

I assume that you meant to set a new line by using "\n" - if so, please, note, that the message can also parse HTML and "\n" will not produce a new line even if it did not broke the js but you have escaped it. To achieve what you need, please, use the <br/> tag as shown below:

String ErrorMessage = "UserName and/or Password in combination with the Institution were not valid. Please try again.<br/>";

ErrorMessage = ErrorMessage + "Specifically, " + (String) ex.LocalMessages[0] + "<br/>";

ErrorMessage = ErrorMessage + "Please contact Ividix Support if you feel that this error is incorrect.";

Please, test my suggestion and let me know how it goes.

Best wishes,
