    The control with ID not found

    I created a window by code behind, but when I try to capture the event to close I get an error saying it is not possible to find the control id.

    protected void LoadWindowFromCodeBehindWithParams(object sender, DirectEventArgs e)
    {
    	int myid = 0;
    
    	Ext.Net.Window win = new Ext.Net.Window();
    	win.ID = "wmId";
    	win.Width = Unit.Pixel(1185);
    	win.Height = Unit.Pixel(660);
    	win.Scrollable = ScrollableOption.Disabled;
    	win.Modal = true;
    	win.Loader = new ComponentLoader();
            win.Loader.Url = "~/App/mypage.aspx?id=" + myid;
    	win.Loader.Mode = Ext.Net.LoadMode.Frame;
    	win.Loader.LoadMask.ShowMask = true;
    
    	win.DirectEvents.Close.Event += MyMethod;
    
       	win.Render(this);			
    }
    public void MyMethod(object sender, DirectEventArgs e)
    {
    string value = "ok";
    }

    Unfortunately, this scenario just doesn't work in ASP.NET Web Forms.

    The two requests are stateless and in the second request, the Event handler is not aware of the Window control created in a previous request.

    You could try something like this...

    public void MyMethod(object sender, DirectEventArgs e){
        Ext.Net.Window win = new Ext.Net.Window();
        win.ID = "wmId";
        
        string value = "ok";
    }
    Another option would be calling a DirectMethod instead of DirectEvent.

    Hello. Thanks for replay.


    With this code the same error happens.

    public void MyMethod(object sender, DirectEventArgs e){
        Ext.Net.Window win = new Ext.Net.Window();
        win.ID = "wmId";
        
        string value = "ok";
    }
    Another option would be calling a DirectMethod instead of DirectEvent.
    Could you give a code example of how I would do this?

    Thanks.
