    In an aspx page I have an user control which in turn opens a modal popup which is
    another user control.

    In the usercontrol in modalPopup I have a check box with a checkedChanged event.

    When the checkbox is checked, I check/uncheck all items in a check box list in the user control.

    However when the event is completed it closes the modal popup. How do I avoid the modal
    popup from being closed. I do not have a modalpopupextender property in user control

    I tried using return statement, it does not work.

    ANy input is appreciated.


    Code (Text):

    protected void CheckBoxSelectAll_CheckedChanged(object sender, EventArgs e)
            Int32 indexCount = 0, totalCount = 0;
            totalCount = Convert.ToInt32(cblLevelList.Items.Count);
            Control ctrl = (Control)FindControl("ModalPopupExtenderLevel");
            if (CheckBoxSelectAll.Checked)
                for (indexCount = 0; indexCount < totalCount; indexCount++)
                    cblLevelList.Items[indexCount].Selected = true;
                for (indexCount = 0; indexCount < totalCount; indexCount++)
                    cblLevelList.Items[indexCount].Selected = false;


    <asp:Panel ID="PanelLevelHeader" runat="server" style="height:250px;position:absolute;width:320px;text-align:center;" HorizontalAlign="Center">
            <asp:CheckBox  id="CheckBoxSelectAll" runat="server" Text="Select All"
                     ToolTip="Click to select all Level"
                  OnCheckChanged="CheckBoxSelectAll_CheckedChanged" CausesValidation="True" AutoPostBack="True">

             <asp:Panel ID="PanelLevelDetail" runat="server" style="height:200px;width:320px;margin-top:10px;background-color:#fff; "       ScrollBars="Auto">
