Problem with Window and obtaining data from controls + Upload of file
Hello All,
I have problem with using of Ext.Net.Window in my project. I can display window, add a directmethod to button in window, but when i click on
this button i enter in direct method function but then i cant get data from any of controls .
Here is a small example of what i'm doing :
File: Default.aspx

<ext:Button runat="server" ID="ButtonHandler" Text="Handler" X="120" Y="10" ></ext:Button>
</Items>
</ext:Viewport>
</div>
</form>
</body>
</html>
File : Default.aspx.cs
=======================================
using System;
using System.Collections.Generic;

using System.Web.UI;
using System.Web.UI.WebControls;
using Ext.Net;
namespace WebApplication2
{
public partial class _Default : System.Web.UI.Page
{
public Window1 wndRegFile;
protected void Page_Load(object sender, EventArgs e)
{
ButtonHandler.Listeners.Click.Handler = "DM.MainPage.HandlerButtonAdd();";
wndRegFile = new Window1();
this.Controls.Add(wndRegFile);
}
[DirectMethod]
public void HandlerButtonAdd()
{
wndRegFile.Hidden = false;
wndRegFile.Render();
}
}
}
File : Window1.cs
=======================================
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Ext.Net;
namespace WebApplication2
{
public partial class Window1 : Ext.Net.Window
{
public Ext.Net.FormPanel formUpload;
public Ext.Net.FileUploadField fileUpload;
public Ext.Net.TextField fileName;
public Ext.Net.Button btnUpload;
public Window1()
{
this.ID = "id_window_reg_file";
this.Height = 600;
this.Width = 800;
this.Hidden = true;
CreateControls();
}
public void CreateControls()
{
this.fileUpload = new Ext.Net.FileUploadField { ID = "id_fldUpload", AllowBlank = false, Width = 200, RenderTo = "formFileUpload", IsFormField = true };
this.fileName = new Ext.Net.TextField { ID = "id_fldName", Name = "fName", AllowBlank = false, FieldLabel = "Name", X = 50, Y = 50, Width = 200, IsFormField = true };
this.btnUpload = new Ext.Net.Button
{
ID = "id_btnUpload",
Text = "Upload file",
Listeners = { Click = { Handler = "Ext.net.DirectMethod.request('Test', {control: 'id_window_reg_file'});" } }
};
this.Buttons.Add(this.btnUpload);
this.formUpload = new Ext.Net.FormPanel
{
ID = "id_formFileUpload",
FileUpload = true,
RenderFormElement = true,
LabelAlign = LabelAlign.Top,
Border = false,
BodyStyle = "background:transparent;padding:10px;",
Items =
{
this.fileUpload,
this.fileName
}
};
this.formUpload.RenderTo = "id_window_reg_file";
this.Items.Add(this.formUpload);
return;
}
[DirectMethod]
public void Test()
{
return;
}
}
}
Same happens if i didnt call DirectMethod from listeners, but when using DirectEvents like
this.btnUpload.DirectEvents.Click.Event += this.AddClick_Event;
this.btnUpload.DirectEvents.Click.EventMask.ShowMa sk = true;
this.btnUpload.DirectEvents.Click.EventMask.Msg = "Sending data to server...";
Then, again i'm going in function AddClick_Event but, cant read any data from window , ie
fileUpload.Text is empty string.
Can anyone help or provide info where i'm wrong?
Also, next question will be, how to do file upload from here using web service :)
