Find ASP.NET Child Controls

To find out child control from parent control we use "$" acts as the delimiter.

Syntax for find out child control from parent control is parentControlID$childControlID.

Here, I give example to DefaultFocus attribute of the < form > element to set the focus to a TextBox nested within a FormView control.


<form id="form1" runat="server" DefaultFocus="vwTest$txtName">
<div>
<asp:FormView ID="vwTest" runat="server">
<ItemTemplate>
Name: 
<asp:TextBox ID="txtName" runat="server" 
Text='' />
</ItemTemplate>
</asp:FormView>
</div>
</form>

Notice that the DefaultFocus attribute refers to the parent control first (the FormView) and then to the child control (the TextBox) using the vwTest$txtName syntax.
