c# - Refresh DataGridView in Windows form

Question

I have two forms let it be Form A and Form B. When I click save button on Form B I want the DataGridView of Form A to refresh.

Which method should I use?

Answer 1

Using a event is one way of doing this. Below is another way which is more object oriented.

Add public Refresh method in FormA.

public void RefreshDataGrid()     
{       
   //Do refresh    
}

Pass the instance of FormA to FormB when constructing FormB. You have to create FormB contructor to take FormA instance.

    private FormA myFormA;        
    public FormB(FormA formA)        
    {        
        myFormA = formA;        
    }

Now you can call FormA.ResfreshGrid() method from FormB.

myFormA.RefreshGrid();
