RequiredFieldValidator + CheckBox ?

[Simon]

Is it possible to use a RequiredFieldValidator to validate a CheckBox there-by
making the checking of it mandatory for submission of the form?

I've tried adding a RequiredFieldValidator for the checkbox and all i get
is an error message: Control 'deleteDisclaimerCheckbox' referenced by the
ControlToValidate property of 'deleteDisclaimerValidator' cannot be validated.

Here's the code snippet...

<asp:CheckBox ID="deleteDisclaimerCheckbox" runat="server" />
<asp:RequiredFieldValidator ID="deleteDisclaimerValidator" ControlToValidate="deleteDisclaimerCheckbox"
Runat="server" />

Hi Simon,

The CheckBox control is not listed in the documentation as a control that can be
validated. Per the docs, the controls that can be validated are: TextBox,
ListBox, DropDownList, RadioButtonList,
System.Web.UI.HtmlControls.HtmlInputText,
System.Web.UI.HtmlControls.HtmlInputFile, System.Web.UI.HtmlControls.HtmlSelect
and System.Web.UI.HtmlControls.HtmlTextArea.

If you want to use the Validator controls, you could put "Yes" and "No" values
into a ListBox or a RadioButtonList. Then use the RequiredFieldValidator to make
sure one or the other value was entered and a RegularExpressionValidator to make
sure "Yes" was entered.

Ahh... well that explains things, i scanned the docs in visual studio but
couldn't find any reference as to what controls can have a RequiredFieldValidator
applied to them. Thanks for your list.

Am going to try using a CustomValidator, that way i can still use the checkbox.

Cheers,
Simon.
