Sometimes you want to call the user control method on this page
Sometimes you want to set the value of the control in the user control on this page.
The following is a solution
First, create a user control uc. ascx
Place a Label and set its value to test.
This. Label1.Text = "test ";
Add a method to this user control.
Public void aa ()
This. Label1.Text = "The method for calling the user control on this page is successful ";
Create a webform to import this user control
<% @ Register TagPrefix = "aa" TagName = "bb" Src = "uc. ascx" %>
<Aa: bb id = "top" runat = "server"> </aa: bb>
Place two buttons on the page
Add to Button 1 event
(Uc) this. FindControl ("top"). Label1.Text = "successfully set the value of the control in the user control on the page"; // this Label1 is the Label in the user control
Add the second button to the event
(Uc) this. FindControl ("top"). aa ();
The preceding two buttons are used to complete the preceding two operations. In the code above, uc is the class name of the user control (that is, the name of the user control). If not, add the name of the namecontrol before it.
