從另一個模態窗體修改打開窗體上的控件？

Question

如何從另一個窗體中引用控件，例如，我從另一個具有DataGrid的窗體打開模態窗體，如何從模態窗體向RadGridView添加行。

備考打開 - >按鈕打開formB模式 - > formB代碼添加radgridview行FORMA - >關閉formB - > FORMA已添加的行:)

從formB嘗試：

formA.radgridview1.rows.add("data") 

沒有果:(

Answer 1

聲明您作爲RadGridView的數據源作公衆在Form1窗體2的內部和內部行添加到DataTable，而不是RadGridView的數據表。

裏面Form1中

Public DataTable1 As New DataTable 

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load 
    DataTable1.Columns.Add("data") 
    DataTable1.Rows.Add("Test row from Form A") 
    RadGridView1.DataSource = DataTable1 
End Sub 

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click 
    Dim Form2 As New Form2 
    Form2.ShowDialog() 
    Form2.Dispose() 
End Sub 

內部窗體2

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click 
    Form1.DataTable1.Rows.Add("Test row from Form B") 
End Sub
