Here is a small series to bring you an article WinForm C # The subform closes the instance of the parent form. Small series feel very good, now share to everyone, also for everyone to make a reference. Let's take a look at it with a little knitting.

The parent Form Form1 Subform Form2 Form1 has a DataGridView control and an Add button,

Form2 has a text control and a save button that asks for a click on the Add button on the Form1 form, pops up Form2,

Then text inside the input content, click Save to automatically close Form2, refresh the data in the Form1 DataGridView

In From1:

private void Button3_Click (object sender, EventArgs e)     {       Form2 F2 = new Form2 ();       F2. ShowDialog ();       if (F2. DialogResult = = DialogResult.OK)       {         this.datagridbind ();//Rebind       }            }

In From2:

<br><br>private void Button1_Click (object sender, EventArgs e) {string s Trconn = "server=.;        Database=filessync;uid=sa;pwd=123 ";        SqlConnection conn = new SqlConnection (strconn);        String sql = "INSERT into asyncfilelist values ('" + textBox1.Text.ToString () + "')"; Conn.        Open ();        SqlCommand mycmd = new SqlCommand (SQL, conn);        Mycmd.executenonquery (); Conn.       Close (); This.       DialogResult = DialogResult.OK;       MessageBox.Show ("add success"); This.            Close (); }
