Control.Parent Property

Gets a reference to the server control's parent control in the page control hierarchy.

[Visual Basic]
Public Overridable ReadOnly Property Parent As Control
[C#]
public virtual Control Parent {get;}
[C++]
public: __property virtual Control* get_Parent();
[JScript]
public function get Parent() : Control;

Property Value

A reference to the server control's parent control.

Remarks

Whenever a page is requested, a hierarchy of server controls on that page is built. This property allows you to determine the parent control of the current server control in that hierarchy, and to program against it.

Example

[Visual Basic, C#] The following example sets a new Control object on a page, myControl1, to the control specified in a FindControl method call. If the call returns a control, the code uses the Parent property to identify the control that contains myControl1. If the parent control exists, the string "The parent of the text box is" is concatenated with the ID property of the parent control and written to the Page. If no parent control is found, the string "Control not found" is written.

[Visual Basic] 

   Private Sub Button1_Click(sender As Object, MyEventArgs As EventArgs)
         ' Find control on page.
         Dim myControl1 As Control = FindControl("TextBox2")
         If (Not myControl1 Is Nothing)
            ' Get control's parent.
            Dim myControl2 As Control = myControl1.Parent
            Response.Write("Parent of the text box is : " & myControl2.ID)
         Else
            Response.Write("Control not found.....")
         End If
   End Sub


[C#] 
private void Button1_Click(object sender, EventArgs MyEventArgs)
{
      // Find control on page.
      Control myControl1 = FindControl("TextBox2");
      if(myControl1!=null)
      {
         // Get control's parent.
         Control myControl2 = myControl1.Parent;
         Response.Write("Parent of the text box is : " + myControl2.ID);
      }
      else
      {
         Response.Write("Control not found");
      }
}
