    .Net Usercontrols with ValidationSummary

    UI Questions

    Hi,

    I am having real trouble getting a usercontrol macro to work whilst placed via the RTE and rendered using umbraco.library:RenderMacroContent. The problem only seems to be when I include a ValidationSummary control within the usercontrol. Here is the error I get on render:

    <!-- Error generating macroContent: 'System.NullReferenceException: Object reference not set to an instance of an object.

       at System.Web.UI.WebControls.ValidationSummary.GetErrorMessages(Boolean& inError)

       at System.Web.UI.WebControls.ValidationSummary.Render(HtmlTextWriter writer)

       at umbraco.library.RenderMacroContent(String Text, Int32 PageId)' -->

    I have no problem including this macro via a template :S

    Any help is much appreciated.

    Hi Scott,

    Unfortunately I don't think RenderMacroContent works well with usercontrols that contain any server-side forms.  You'd have to output the content in the template for it to work properly -- or use a Razor macro or other solution.

    Sorry there's not better news!
