Question

I have 2 forms. Form1 contains a datatable. When I instantiate form2, I pass it one record from form1’s datatable. Then I do some things in form2, and now I want to update the datatable in Form1, based on what was done in form2.

How can I accomplish this? I need to remove datarows, and add new datarows, and I must have the data from form2 to accomplish this.

Answer 1

From this post:

• Create a public property in form2:

  public partial class Form2 : Form {
  
      private DataTable data;
  
      public DataTable Data {
          get { return data; }
      }
  }
  

• And access it in form1 when you’re done with form2:

  //...
  form2.ShowDialog();
  // Retrieved modified dataTable
  dataTable = form2.Data;
  //...
