Code:

<script language="JavaScript">

document.all["buttonName"].onclick = new function("Page_ValidationActive=true;");

</script> 
 


Page.Validate()

If Page.IsValid Then
	Lblerror.text = "your custom error message"
	If Validationsummary1.Visible = True Then
		Validationsummary1.Visible = False
	End If
Else
	If Validationsummary1.Visible = False Then
