Example

It is recommended to work with this component in design time. For example, if you create the SqlDataTable object (“myDataTable1”) on Form1, you can access Form1's myDataTable1 via the DataSource property of Form2's DataLink object (“dataLink1”). In this case, you will find the following entry in Form2.InitializeComponent():

csharp

private void InitializeComponent() {
        ...
        this.dataLink1.DataSource = ((object)(Devart.Common.GlobalComponentsCache.GetObjectByName("Form1.myDataTable1")));
        ...
}

Visual Basic

Private Sub InitializeComponent()
        ...
        Me.DataLink1.DataSource = CType(Devart.Common.GlobalComponentsCache.GetObjectByName("Form1.myDataTable1"), Object)
        ...
End Sub
