Hi Anis Make sure few things: - a. If you are using asp.net 3.5 then Change: asp:ToolkitScriptManager r ID=ScriptManager1 runat=server> asp:ToolkitScriptManager> to: asp:ScriptManager> and use mask masktype property like Mask= 99:99:99 MaskType= Time because MaskedEdit control needs to be rendered with the Mask and MakeType properties. b. If this wont work then Compile using .NET 3.5 without SP1. --OR-- Install SP1 on the on system If still it won't work then take my code Namespace=AjaxControlToolkit TagPrefix=asp %> Use of Maksed TextBox Mask=99:99:99 CultureAMPMPlaceholder= CultureCurrencySymbolPlaceholder= CultureDateFormat= CultureDatePlaceholder= CultureDecimalPlaceholder= CultureThousandsPlaceholder= CultureTimePlaceholder= Enabled=True TargetControlID=TextBox1 MaskType=Time> webconfig ------------ Note: As an alternative to hand editing this file you can use the web admin tool to configure settings for your application. Use the Website->Asp.Net Configuration option in Visual Studio. A full list of settings and comments can be found in machine.config.comments usually located in \Windows\Microsoft.Net\Framework\v2.x\Config --> Set compilation debug=true to insert debugging symbols into the compiled page. Because this affects performance set this value to true only during development. --> The section enables configuration of the security authentication mode used by ASP.NET to identify an incoming user. --> The section enables configuration of what to do if/when an unhandled error occurs during the execution of a request. Specifically it enables developers to configure html error pages to be displayed in place of a error stack trace. --> The system.webServer section is required for running ASP.NET AJAX under Internet Information Services 7.0. It is not necessary for previous version of IIS. --> if wont work then send me your email i will send you my solution.
