Inter Module Communication in DNN using C#

Well, this post I will share with you my finding about the DNN IMC, something like you want to pass 1 or more values from one module to another module, imagine you created 2 modules, one is search module another one is result list module. You type something in search module and hit “go”, the value from search module will pass to result list module, for instance.

OK, stop the crap.

in sender module,

import this
using DotNetNuke;
using DotNetNuke.Entities.Modules;
using DotNetNuke.Entities.Modules.Communications;

Extend the Interface
public partial class Training : PortalModuleBase, IModuleCommunicator

Declare this
public event ModuleCommunicationEventHandler ModuleCommunication;

Here the button Click
 protected void btnSearch_Click(System.Object sender, System.EventArgs e)
  {
  try
  {
  ModuleCommunicationEventArgs MCArgs = new ModuleCommunicationEventArgs();
  MCArgs.Sender = "ACS.BCU_Training.Search";
  MCArgs.Target = string.Empty;
  MCArgs.Text = "Search Text is " + txtSearch.Text;
  MCArgs.Value = txtSearch.Text;

  if (ModuleCommunication != null)
  {
  ModuleCommunication(this, MCArgs);
  }
  }
  catch (Exception exc) //Module failed to load
  {
  Exceptions.ProcessModuleLoadException(this, exc);
  }
}


In Receiver Module,

import this
using DotNetNuke;
using DotNetNuke.Entities.Modules;
using DotNetNuke.Entities.Modules.Communications;

extend the interface
partial class View_Training : PortalModuleBase, IActionable, IModuleListener

put this method
public void OnModuleCommunication(object s, ModuleCommunicationEventArgs e)
{
if (e.Sender == "ACS.BCU_Training.Search")
{
string imcValue = (string)e.Value;
BindList(imcValue);
}
}

in BindList, just normal pass the value to business object to retrieve a list of data you want.
