Question

I have a question about a third-party DateTimePicker control.
I’ve downloaded the dll and paste the appropriate web.config lines.
I’ve put the control into the aspx page. When I load the page an alertbox appears:

No «add verb=”GET” path=”/JavascriptDateTimeFormat.axd” /» httpHandler.

The control’s textbox and the buttons are present but does nothing.

Part of my web.config is:

<pages>
  <controls>
    <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add tagPrefix="mark" assembly="Mark.Web.UI.WebControls.DateTimePicker" namespace="Mark.Web.UI.WebControls"/>
  </controls>
</pages>
<httpHandlers>
  <remove verb="*" path="*.asmx" />
  <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
  <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
  <add verb="GET,HEAD" path="ScriptResource.axd" validate="false" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
  <add verb="GET" path="/helpdeskweb/JavascriptDateTimeFormat.axd" type="Mark.Web.UI.JavascriptDateTimeFormat, Mark.Web.UI.WebControls.DateTimePicker"/>
</httpHandlers>

What should I do?

Answer 1

Add this entry into web.config between HttpHandlers tag

add verb=”GET” path=”JavascriptDateTimeFormat.axd” type=”Mark.Web.UI.JavascriptDateTimeFormat, Mark.Web.UI.WebControls.DateTimePicker”

make sure the path is as mention in bold.
