I'm not sure if this helps... but when runat = "server" you can set the ExpandControlID and the CollapseControlID to "". Then reset it back when finished.

e.g.,

<Ajax:CollapsiblePanelExtender SkinID="CollapsiblePanelExtenderPlusMinus" ID="cpeOne"
    runat="server" TargetControlID="pnlOne" ExpandControlID="pnlHeadingOne"
    CollapseControlID="pnlHeadingOne" Collapsed="false" 
    ImageControlID="imgPlusMinusOne"
    SuppressPostBack="false">
</Ajax:CollapsiblePanelExtender>

<asp:Panel ID="pnlHeadingOne" runat="server">
    <h3>
        <asp:Image runat="server" ID="imgPlusMinusOne" ToolTip="Show/Hide details" />
    Details
    </h3>
</asp:Panel>

Then in code behind - when clicking on an Edit button:

protected void BtnEditClick(object sender, EventArgs e) {
    DisableCollapsiblePanelExtenders();
}

private void DisableCollapsiblePanelExtenders() {
    this.cpeOne.ExpandControlID = "";
    this.cpeOne.CollapseControlID = "";         
}

// Reset the CollapsiblePanelExtender
private void EnableCollapsiblePanelExtenders() {
    this.cpeOne.ExpandControlID = this.pnlHeadingOne.ID;
    this.cpeOne.CollapseControlID = this.pnlHeadingOne.ID;
}
