HTML 5 Required Validator Triggers On All Buttons On The Form

Solution 1:

Add formnovalidate tag in each buttons html code.

<asp:ImageButton ID="Cancel" runat="server" ImageUrl="~/Images/ClaimForm/btnCancel.gif" OnClick="btnFallBack_Click" Visible="False" ToolTip="Cancel" draggable="false" formnovalidate="formnovalidate" />

Solution 2:

I solved it by assigning an onclick function to that button and adding:

event.preventDefault();

Solution 3:

try this.

use a input button - where set the type as button and make it to run as server

ex: // this will trigger the required for text boxes

//this button will not.
