Close window - client and server side

[Hanza]

From main page I display window with autoload of some other URL with detail form. In this detail form there are two buttons - Save and Cancel.
Questions:
1) How to close window after process saving in directEvent?
2) How to close window on Cancel button - it works over listener handler and "window.parent.DetailsWindow.close();" but how to do this more "universal" if I use detail form from some other page where window doesn't have ID "DetailsWindow"

On main page I have

<script runat="server">
  protected void ShowDetails(object sender, DirectEventArgs e)
  {
    this.DetailsWindow.Show();
  }
</script>
<ext:Button runat="server" ID="bDetail" Text="Detail" Icon="Add">
  <DirectEvents><Click OnEvent="ShowDetails" /></DirectEvents>
</ext:Button>
...
<ext:Window ID="DetailsWindow" runat="server" Icon="Group" 
    Title="Entity details" Width="600" Height="400"
    AutoShow="false" Modal="true" Hidden="true"		
    Layout="Fit" >
  <AutoLoad Url="FormDetails.aspx" Mode=IFrame />
</ext:Window>

in FormDetails.aspx:

<script runat="server">
  protected void SaveDetails(object sender, DirectEventArgs e)
  {
    //process saving...
    //how to close window
    this.parent.close(); //wrong
  }
</script>
...
<Buttons>    
        <ext:Button ID="btnSave" runat="server" Text="Save" Icon="Disk">
           <DirectEvents><Click OnEvent="SaveDetails" /></DirectEvents>
        </ext:Button>
        
        <ext:Button ID="btnCancel" runat="server" Text="Cancel" Icon="Cancel">
            <Listeners>
                <Click Handler="window.parent.DetailsWindow.close();" />
            </Listeners>
        </ext:Button>
    </Buttons>

Hello!

I think this link would be useful for you:
https://examples1.ext.net/#/Events/D...hods/Overview/.

You need to know more about a success handler of DirectEvent.

Example

<script runat="server">
    [DirectMethod]
    public string GetTimeStamp()
    {
        return DateTime.Now.ToLongTimeString();
    }
</script>

<ext:Button runat="server" Text="Click Me" Icon="Lightning">
    <Listeners>
        <Click Handler="
            Ext.net.DirectMethods.GetTimeStamp({
                success: function (result) {
                    Ext.Msg.alert('Server Time', result);
                }
            });" />
    </Listeners>
</ext:Button>
