First to call JavaScript function, use OnClientClick. To avoid page refresh, after your function call add return false;

For example:

<asp:Button ID="btnSubmit" runat="Server" OnClientClick="btnsave_Click(); return false;" />

bt, how to execute btnsave_Click event

ebram khalil Over a year ago

@aparnarai, remove return false; .. The return false is to stop hitting the server back

aparna rai Over a year ago

after remove return false, again reload the whole page, how to stop page refresh

ebram khalil Over a year ago

if you want to execute server-side code then you either, 1- post back to the server; hence refresh the page, or 2- make an AJAX call
