Solution 1

remove this line

window.onload = Show;

this will invoke the button click event as soon as the page is loaded, hence infinite loop will occur.

but i need the javascript to load as the page is loaded..On removing this the javascript will not work when the page is loaded..
also i tried to use jQuery and its not loaded when the page is loaded
$(window).load(function () {
document.getElementById('<%= bttn.ClientID %>').click();
});

so is there any other way to stop that reload??

what is your requirement.

Palash Sachan 3-Mar-17 4:54am

my requirment is very small..what here i want to do is-->
"when and as soon as the webform7.aspx page is fully loaded then it should auto click the button which will invoke the code behind method and do the stuff"

I did this only but the page is reloading and i need to stop the reload..

ok, you have got a solution.

yeah..thanks for the help :)

Here is why it happens: onload is set to Show, and this method triggers a button click. And when you click the button, your browser posts a request to the server and shows you the response, this is why the page reloads. And when the page reloads, Show is called again so it goes on forever.

I don't know what you want to do exactly so I can't say what you have to do now, but if you know the cause, you should be able to resolve it.

Put a placeholder around your script

    <asp:Placeholder ID="PlaceScript" runat="server">
        <script type="text/javascript">
            function Show() {
                document.getElementById('<%= bttn.ClientID %>').click();
        }
        window.onload = Show;
    </script>
</asp:Placeholder>

then hide the placeholder when the button is clicked

protected void bttn_Click(object sender, EventArgs e)
{
    success.Visible = true;
    PlaceScript.Visible = false;
}
