Answering this question might not be useful to the person who posted it but it might be useful to others.

The following needs to be done to close the modal popup from server side.

Instead of giving the close button id to "CancelControlID" of the modalpopupextender, create a dummy hiddenfield and give this id to "CancelControlID" of the modalpopupextender.

for example

<pre>
<asp:HiddenField ID="hidForModel" runat="server" />;
/*Are you sure you want to know the answer? */
    <asp:Button ID="btnYes" runat="server" Text="Yes!" onclick="btnYes_Click" />;
    <br />;
    <asp:Panel ID="pnlModal" runat="server" CssClass="modalPopup" Style="display: none;">
        <asp:Panel ID="pnlControls" runat="server" CssClass="insideModalPopup></asp:Panel>
        <br />
        <asp:Button ID="btnClose" runat="server" Text="Close" onclick="btnClose_Click" />
    </asp:Panel>
        <cc1:ModalPopupExtender TargetControlID="hidForModel" ID="pnlModal_ModalPopupExtender"
        runat="server" DynamicServicePath="" Enabled="True" BackgroundCssClass="modalBackground"
        PopupControlID="pnlModal" CancelControlID="hidForModel" DropShadow="true">
        </cc1:ModalPopupExtender>
</pre>

Here i have given both TargetControlID and CancelControlID as hidForModel as I want to show as well as hide the modal popup from code-behind.

In Code-Behind

<pre>

        protected void btnYes_Click(object sender, EventArgs e)
        {
            pnlModal_ModalPopupExtender.Show();

            TextBox txt = new TextBox();
            txt.Text = "aaa";
            pnlControls.Controls.Add(txt);
        }

        protected void btnClose_Click(object sender, EventArgs e)
        {
            pnlModal_ModalPopupExtender.Hide();
        }
</pre>

Here I have made the modal popup seen and added a textbox from code-behind on click of yes button and hidden the modal popup on click of Close button.
