Controls that traverse the page of the Application Master page in ASP.

You should figure out what the controls are on the first floor.

The control we are looking for is generally on the fourth floor site1_master---contentplaceholder---HtmlForm---CheckBox

First floor is site1_master, master

The second floor is ContentPlaceHolder, which is the ' pit ' of the master version,

The third layer is HtmlForm, which is the HTML form,

The fourth layer is the child control.

So you have to iterate.

The following example uses a multi-layered traversal to find a checkbox in a page and lists each layer name

String S= "";

for (int i = 0; i < Page.Controls.Count; i++) all controls in//site1_master
{
foreach (Control conn in page.controls[i]. Controls)//traversing in Site1_master, looking for ContentPlaceHolder
{
foreach (Control con in Conn. Controls)//Traversal in ContentPlaceHolder, looking for HtmlForm
{
foreach (Control C in con. Controls)//traversing in HtmlForm, looking for a checkbox
{
if (C.gettype (). Name.equals ("checkbox"))
{
S=conn. GetType (). Name + "---" + con. GetType (). Name + "---" + c.gettype (). Name;
}

}
}

}
}

Novice, there are errors please correct me, thank you!
