Backend user controls: How to set-up validation for then?

Hi.

I've made a very simple user control for tests in the backend. It's a combobox with 3 values:
- Choose (empty string)
- Male ("M" string)
- Female ("F" string)

The control is working, the data is being saved in umbraco database. However, if I check the "required" option for this type in the document type properties, umbraco ignores this and allows contents to be saved with this field empty.

What can I do to handle validation for my backend user control?

Thanks!

Fernando

I believe you can use the ValidationPropertyAttribute (http://msdn.microsoft.com/en-us/library/system.web.ui.validationpropertyattribute ) but I don't think it's 100% reliable.

I'd recommend that you do validation by putting your own validation controls into the User control. I don't know how (or if it's possible) to work out from a data type whether it is set as a 'required' property on a document type (without a lot of nasty hacks :P)

Hi Slace.

Thanks! You're right. I used a "Required Field Validator" inside the user control, and now it works like a charm!

Thank you again for the help.

Hi Giacomo.

Here goes the code:

<asp:RequiredFieldValidator ID="myFieldRequiredValidator" runat="server" 
     Display="None" EnableClientScript="false" 
     ControlToValidate="myDropDownList"
     ErrorMessage="The field MyField is mandatory!">
</asp:RequiredFieldValidator>
