get and set the value of controls inside a panel which is itself inside a tableLayout Panel

I have a tableLayoutPanel inside which i have added Panels dynamically--- the name of Panels are :

Panel1 , Panel2 . . . . . . . . . . . Panel10

Now , in these dynamically added Panels , am adding some more controls dynamically such as :

In Panel1 : LabelDate1, LabelTime1, LabelPicAdder1, LinkLabel1

In Panel2 : LabelDate2, LabelTime2, LabelPicAdder2, LinkLabel2......

Now , on a button click, i want to change the values of the controls inside the Panel1, Panel2, but if i do this :

foreach ( Control ctrl in this.tableLayoutPanel )

, i am ONLY able to get the Panels into ctrl variable,

but how to get the controls inside these Panels into some variable and change the TEXT property of those controls.....

I mean, how do i get the controls which are inside the Panels, which are themselves inside the tableLayoutPanel

TableLayoutPanel---->Dynamic Panels----------->Dynamic Controls --how to change the text property of this last object in the hierarchy

create a Recursive function like this to read all control in a parent and child control

 public void GetAllControl(Control parent)
        {
            //Dosomething with parent like setting text or blah blah blah

            foreach (Control item in parent.Controls)
            {
                GetAllControl(parent);
            }
        }

and call this loop every where you want

foreach ( Control ctrl in this.tableLayoutPanel )
{
GetAllControl(ctrl );
}

You added the control to the panels. So you have to iterate each panel:

foreach ( Control panel in this.tableLayoutPanel ) {
    foreach ( Control ctrl in panel) {
        // etc..
    }
}

Odds are good that you can simplify your code by storing the control references when you create them instead of trying to find them back later.
