i got a good solution- put a button outside the ModalPopupExtender and submit the button by javascript and put java script code inside the okscript();Outside button cause postback.

<asp:modalpopupextender id="mpeSave" runat="server" backgroundcssclass="ModalPopupBG" xmlns:asp="#unknown">
BehaviorID="mpebSave" CancelControlID="btnPopupNo" DropShadow="True" OkControlID="btnPopupYes"
OnCancelScript="hidePanel('C')" OnOkScript="hidePanel('Y');" PopupControlID="pnlOverlaySave"
TargetControlID="pnlOverlaySave">

<asp:panel id="pnlOverlaySave" runat="server" horizontalalign="Left" style="display: none" xmlns:asp="#unknown">
Width="330px">

Action Status:

<%--The content will go here--%>
<asp:label id="lblPopupSaveMessage" runat="server" font-bold="True" font-names=" Tahoma, Arial">
Font-Size="Small" ForeColor="#0063FF">

<asp:button id="btnPopupYes" runat="server" text="Yes" width="90px" onclick="btnPopupYes_Click">

type="button" value="No" />

<asp:button id="btnReset" runat="server" text="Reset" onclick="btnReset_Click" xmlns:asp="#unknown">

function hidePanel(var1) {
window.$get('<%= pnlOverlaySave.ClientID %>').style.display = "none";
window.$find('mpebSave').hide();
if (var1 == 'Y') {
//this is the button event which cause postback
window.parent.document.getElementById('<%=btnReset.ClientID %>').click();

Generally with postback ModalPopup get disable or invisible. You have to write ModalPopup1.Show(); Method after which u wants to show. you can set a counter in your program and against a button inside modal popup you can increse its value and in pageload you can check if its value is not incremented then Modalpopup1.Show();
This problem is solved in floating div. you can try floating div also inplace of modalpopup. It performs the same operation.
