I have a UserControl(UCPickList:-TextBox+Button+Label) in a project, using this project dll into another project, don't want to change the existing code. I just want to use this dll into my project and want to access Button_Click Event into my new project without using any other control on this form. I am unable to solve this issue from my side, i tried google but not satisfied.
Please suggest through logic/some source code.

Can't you just expose the Button Click Event Handler as public on your User Control. Then attach the click event within your code that calls the user control from DLL? Or is that too simple/im not getting something here.

Follow the steps:

Quote:
1. Create your own custom event in the user control.
2. Wire the Parent Page up to handle that event.

It's the same exact technique you are doing in the user control when you handle a button's click event. The code there isn't calling an event, it's wiring up the handler in the parent page.

Try this
Control code

C#

public delegate void UCPickListHandler();
public event UCPickListHandler UCPickList_Click;

protected void Button_Click(object sender, EventArgs e)
{
    if (this.UCPickList_Click != null)
    {
       this.UCPickList_Click();
    } 
}

Page code

onUCPickList_Click event

C#

protected void UCPickList_Click()
{
 //your code
}
