how to avoid _dopostbackwithoption

[CreativeMind]

hi all,
I have a control, when html is rendered , i get javascript on onclick
event, i think it's creating problem for me bkoz i dont debug my own
javascript when i write on its clickevent..

<input type="submit" name="_ctl0:ContentPlaceHolder2:btnSubmit"
value="Submit" onclick="javascript:WebForm_DoPostBackWithOptions( new
WebForm_PostBackOptions(&quot;_ctl0:ContentPlaceHo lder2:btnSubmit&quot;,
&quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, false))"
language="javascript" id="_ctl0_ContentPlaceHolder2_btnSubmit" />

thanx.
