CompareValidator - Strange behavior

Question

User1700504264 posted

Hello

I am using the CompareValidator to ensure that the end date is not earlier than the start date.

it compares two textboxes each of which extended using the (AJAX calendar).

it works <g class="gr_ gr_350 gr-alert gr_gramm gr_inline_cards gr_run_anim Style multiReplace" id="350" data-gr-id="350">fine ,</g> but in some <g class="gr_ gr_401 gr-alert gr_gramm gr_inline_cards gr_run_anim Punctuation only-ins replaceWithoutSep" id="401" data-gr-id="401">cases</g> it <g class="gr_ gr_392 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar multiReplace" id="392" data-gr-id="392">do</g> not work as expected

for example

value in txtActiviityEnd (12/31/2018)

value in txtActivityStart (01/01/2018)

the validator should not be activated in this <g class="gr_ gr_527 gr-alert gr_gramm gr_inline_cards gr_run_anim Style multiReplace" id="527" data-gr-id="527">case ,</g> since it is an acceptable case, but at <g class="gr_ gr_577 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del" id="577" data-gr-id="577">run time</g> it is activated and show the error <g class="gr_ gr_634 gr-alert gr_gramm gr_inline_cards gr_run_anim Style multiReplace" id="634" data-gr-id="634">message !</g>

any help <g class="gr_ gr_646 gr-alert gr_gramm gr_inline_cards gr_run_anim Punctuation only-ins replaceWithoutSep" id="646" data-gr-id="646">please</g>?

                                </asp:CompareValidator>

Try setting the Type attribute to date.  Plus you have an extra ">" syntax error.

<asp:CompareValidator 
	ControlToValidate="txtActivityEnd" 
	ControlToCompare="txtActivityStart" 
	Operator="GreaterThanEqual" 
	ValidationGroup="SaveActivity" 
	ErrorMessage='<% $ Resources:wrongdateinterval %>' 
	Display="Dynamic" 
	CssClass="text-danger" 
	runat="server"
	Type=Date
</asp:CompareValidator>
