DotNetNuke : Pass a data from one module to another module - asp.net

Question

In am developing a website by using DotNetNuke, module by module.
In a page (tab), I have 3 modules. 2 modules are the same module which are Form modules, however I name it for different name (Section A and Section B).
In my Button modules it involve processing of Section A and Section B how can I pass data from Form Modules with Section A and Section B into Button modules within same page (Tabs)?

Answer 1

For that you need the IModuleCommunicator and the IModuleListener interfaces.
On the module that will send data:
public partial class View : Module1, IModuleCommunicator
{
public event ModuleCommunicationEventHandler ModuleCommunication;
protected void Page_Load(object sender, EventArgs e)
{
try
{
sendDataToOtherModule("This is a test.");
}
catch (Exception ex)
{
Exceptions.ProcessModuleLoadException(this, ex);
}
}
public void sendDataToOtherModule(string valueToSend)
{
ModuleCommunicationEventArgs mcea = new ModuleCommunicationEventArgs();
mcea.Target = "TheOtherModule";
mcea.Value = valueToSend;
ModuleCommunication(this, mcea);
}
}
On the module that will receive the data
But you could use this code in every module and check the Target.
public partial class View : Module2, IModuleListener
{
protected void Page_Load(object sender, EventArgs e)
{
try
{
//module code
}
catch (Exception ex)
{
Exceptions.ProcessModuleLoadException(this, ex);
}
}
public void OnModuleCommunication(object sender, ModuleCommunicationEventArgs e)
{
if (e.Target == "TheOtherModule")
{
Label1.Text = e.Value.ToString();
}
}
}
Add using DotNetNuke.Entities.Modules.Communications on both modules.
