Hi,

I have 2 modules on my page; the communication between those 2 modules is working without errors,
The message sent by the Communicator (module2) is received by the listener (module1) successfully.
The code behind of my module2 (the communicator) is :

public partial class DesktopModules_Test_TestUserCon2 : DotNetNuke.Entities.Modules.PortalModuleBase, IModuleCommunicator
{
    public event ModuleCommunicationEventHandler ModuleCommunication;
    protected void Page_Load(object sender, EventArgs e)
    {
        
    }

    protected void Button1_Click(System.Object sender, System.EventArgs e)
    {
        
            ModuleCommunicationEventArgs MCArgs = new ModuleCommunicationEventArgs();
            MCArgs.Sender = "TestCommunication";
            MCArgs.Target = "empty";
            MCArgs.Text =  TextBox1.Text;
            MCArgs.Value = new object();

            if (ModuleCommunication != null)
            {
               ModuleCommunication(this, MCArgs);
            }   
    }
}

The code behind of my module2 (the Listener) is:

public partial class DesktopModules_Test_TestUserCon : DotNetNuke.Entities.Modules.PortalModuleBase,IModuleListener
    
{
     
    protected void Page_Load(object sender, EventArgs e)
    {
      #region IModuleListener Members

       public  void OnModuleCommunication (object s, ModuleCommunicationEventArgs e)
        {
            if (e.Sender == "TestCommunication")
            {
                string imcValue = (string)e.Text;
                TextBox1.Text = imcValue.ToString();
            }
        }
        #endregion
    }

I want to change the text of my TextBox1 in my UserControl - listener (module1) based on the Text sent by the communicator.

Thank You for your help,
Regards,
Elie

I would have thought that would work, but I've not used it yet.

I note that most other examples use e.Value not e.Text for the passing of a value. I can't see why you can't use either, but it'd be worth trying. Certainly you don't need to ToString() on the line in red because you've already cast it to string, but it shouldn't break it.

Hi, Thank you for ur reply, first I’m sorry about the code behind of my module2 (the Listener) I have done a mystique while writing my post, the OnModuleCommunication function should be outside the Page_Load .The code should be like this : Public partial class DesktopModules_Test_TestUserCon : DotNetNuke.Entities.Modules.PortalModuleBase,IModuleListener { Protected void Page_Load(object sender, EventArgs e) { } #region IModuleListener Members public void OnModuleCommunication (object s, ModuleCommunicationEventArgs e) { if (e.Sender == "TestCommunication") { string imcValue = (string)e.Text; TextBox1.Text = imcValue.ToString(); } } #endregion } The values are received by the listener and yes while debugging the values of TextBox1.Text is change according to the sent value = that’s mean that the message is received successfully. The Problem is that in the code behind of the listener the value of TextBox1 is changed but visually it isn’t (it’s like the usercontrol is not rendered) I mean on my website the value of TextBox1 never changes.
