Hi,

I have a date picker control with a required field validator control.  When the page loads the date picker's textbox is empty.  So I select a date, and then delete the date and move the focus to another control on the page, but the required field validator does not fire.  Can some one please explain why?

Hi Brendan,

I tried to implement the same scenario on my end and it is working as expected. Have you set the ErrorMessage property for the RequiredFieldValidator?

Here is the aspx code I tried:
<telerik:RadDatePicker ID="RadDatePicker1" runat="server"
      <Calendar runat="server"  Font-Size="Smaller"  ></Calendar
  </telerik:RadDatePicker> 
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Enter a Date" ControlToValidate="RadDatePicker1" ></asp:RequiredFieldValidator> 
       


Regards
Princy.

Hello Brendan,

I also tested the same scenario and, as Princy mentioned, it works as expected. Please set the ErrorMessage property and let us know how it goes.

Here is my code:

<radcln:RadDatePicker
   ID="rdpExportEndDate"
   Width="120"
   runat="server">
</radcln:RadDatePicker>
<asp:RequiredFieldValidator
   ID="rfvExportEndDate"
   ControlToValidate="rdpExportEndDate"
   Display="Dynamic"
   ErrorMessage="Required"
   runat="server">
</asp:RequiredFieldValidator>

This doesn't fire at all.

Hi,

I took his code, and added it to a new page, I just put it in a form tag.  That's all.  I ran the page and it does not trigger.  Is there some sort of page property that I need to set?

Please find attached a sample runnable project which works as expected. Test it on your aide and let me know what the difference in your case is.

Thanks but that zipped file is too big for me to download.  Can you maybe exclude the dll files please?  I am using Q1 2007.

Hi,

I had a look at the code.  The required field validator only fires when the button is clicked and there is no date.  My scenario is different.  When there is a date and the user clears the date and goes to another control, then it should fire, not only when the button is clicked.

Hello Brendan,

The default behaviour of the Validator control is to to fire validation on postback. I you add regular asp control instead of RadDatePicker the application will behaves in the same way. Please review the following topic which elaborates on Validating control on lost focus event
