Sharepoint DateTime control, how to call client side as well as server side on datechanged

Question

I am having a datetime control in sharepoint custom webpart

<SharePoint:DateTimeControl 
        runat="server" 
        ID="txtUKdtofAdm" 
        LocaleId="2057" 
        DateOnly="True"
        OnValueChangeClientScript="validateControlsUK();" 
        AutoPostBack="true" 
        OnDateChanged="txtUKdtofAdm_OnDateChanged">
</SharePoint:DateTimeControl>

I want to call a js as well as server side function on date changed. I have done as above but, client side function does not execute. Can anyone help me in order to get this working wherein if a date is changed than both js on client side and onchange server side event should work.

In my case only server side is getting fired.

Thank you in advance.

Answer 1

I think you should remove the ; from the end of validateControlsUK(); and it will work. So your call should be like this: OnValueChangeClientScript="validateControlsUK()". Also, be aware, that Javascript is case sensitive. I don't know what is the function name in your javascript, but there is a difference between ValidateControlsUK and validateControlsUK. :) If that didn't work, here are some advice, how to troubleshoot: 1. You could try this line, to see if it's even a valid event you are trying to catch: OnValueChangeClientScript="javascript:alert('Date changed');" 2. If step 1 succeeds, you should put in your function, validateControlsUK, at the very beginning of it, a similar alert as above. This way you will know at least that your client side validation is triggered, but it's ill-performing for other reasons.

I hope this helped.

Ok i got the solution to this.

I removed AutoPostBack="true" and in javascript i used __doPostBack('<%= txtUKdtofAdm.Controls[0].ClientID %>', ''); which forces a postback which inturn fires OnDateChanged="txtUKdtofAdm_OnDateChanged"

Thank You
