I have RadTabStrip on my page. The problem I try to solve is not allow to pass to other tab if validation is failed.
For that I have next controls:
1. Validation controls connected to the specific control such as:
It is just example. As you see this control validation control is part of the some group

<asp:TextBox ID="txtEmployeeNo" CssClass="readOnlyTextbox" runat="server" Enabled="false"  />
<asp:ImageButton ID="imbChangeEmployeeNo" runat="server" ImageUrl="./../Images/Search.gif"
    CommandName="ChangeEmployee" ToolTip="Change Employee" />
<asp:RequiredFieldValidator ID="reqlblEmployeeNoEdit" runat="server" ErrorMessage="Employee No is required."
    Display="None" ControlToValidate="txtEmployeeNo" ValidationGroup="valGrpGeneral" Enabled="false"></asp:RequiredFieldValidator>
2. Validation summary control
<asp:ValidationSummary ID="valSumGeneral" runat="server" DisplayMode="BulletList"
    HeaderText="The following inputs are invalid:" ValidationGroup="valGrpGeneral"
    ShowMessageBox="true" ShowSummary="false" />
3. Tab Client Event
function OnClientTabSelecting(sender, eventArgs) {
    var newTab = eventArgs.get_tab();
    if (newTab != null) {
        var oldTab = newTab.get_parent().get_selectedTab();
        if (oldTab != null) {
            switch (oldTab.get_value()) {
                case "<%= GeneralTabValue %>":
                    eventArgs.set_cancel(!Page_ClientValidate("<%=GeneralTabSummaryValidationName %>"));
                    break;
            
        }
    }

Validation is working OK, but.... There is some other logic related to postbacks stopped to work, immediately after I am using OnClientTabSelecting. For instant, I have button which execute ModalWindow using JavaScript. This modal window is returning some values:
function ShowModalWindow(ctrl1ID, ctrl2ID, ctrl3ID, url) {
    var ret = window.showModalDialog(url, this, 'dialogWidth=975px;dialogHeight=670px;resizable=yes;help=no;');
    var ctrl1 = document.getElementById(ctrl1ID); // 'R' = HR Reason Code, 'E' = Employee ID, 'P' = Position
    var ctrl2 = document.getElementById(ctrl2ID); // The returned value
    var ctrl3 = document.getElementById(ctrl3ID); // Whether or not to open the control in edit mode.
    if (ret != null && ctrl1 != null && ctrl2 != null && ctrl3 != null) {
        if (ret.length > 1) {
            ctrl1.value = ret[0];
            ctrl2.value = ret[1];
            ctrl3.value = ret[2];
        }
    }
}
Once windows is closed in usual situation postback occurs and page is refreshed according to data returned from the windows.

BUT, after OnClientTabSelecting, although javascript is executed, postback doesn't.

Does anyone know what it might be the reason?
