Hi,

you can use event method to pass values from Child to Parent.

Suppose We have two classes names Parent and Child. Then create an event in Child class like

public delegate ValueChangedHandler(DataTable DT);
public event ValueChangedHandler ValueChanged;

Now raise this event from Button event click

if(ValueChanged!=null)
{
   //DT: Suppose it is the desired object to return
   ValueChanged(DT);
}

Now come to Parent class, here you have to handle this event like

Child objChild=new Child();
objChild.ValueChanged += new ValueChangedHandler(objChild_ValueChanged);
objChild.Show();

New method will create with the name "objChild_ValueChanged" like

void objChild_ValueChanged(DataTable DT)
{
  //TODO: Now you can use this value which in coming from Child class.
}

regards
Ankit

Create public property/member in the child window. Say, MyDataTable is a public property in the Child Window.

You must have used the following (similar) code to open the Child Window.

C#

MyChildWindow child = new MyChildWindow();
child.Show();

Now assign the data table value to MyDataTable property from the ChildWindow. You can access it from the Parent Window like,

C#

DataTable table = child.MyDataTable;

Solution 1

You need to create a table on the new window (pass data from child window) - hide the one on the child window.
