[Self-study Notes] ASP. NET tips

1. Change the text on the button

First look at the effect:

1,

2,

3,

One button and one label Control

Code:

Think about it again

Protected   Void Button#click ( Object Sender, eventargs E)
{
// Object sender, the object that triggers this event
// E is the parameter that may be passed when this event is triggered.
// Change the dynamic display text of the button
If (Button1.text =   " Show Details " )
{
Button1.text =   " Hide " ;
Label1.text =   " This shows the detailed information: <br/> name: A 1 <br/> Gender: male " ;
}
Else
{
Button1.text =   " Show Details " ;
Label1.text =   " This is a hidden state! " ;
}

 

Ii. Use Image to control the production of simple ad Rotation

Code

Code

// Definition range: 0-10
Random random =   New Random ();
Int Rannum = Random. Next ( 10 );

If(Rannum< 5)
Linkimage. imageurl=Ima1.gif;
Else
Linkimage. imageurl=Ima2.gif;

 

3. browser Detection

 

Browser Detection

  Protected   Void Button2_click ( Object Sender, eventargs E)
{
Httpbrowsercapabilities Browser = Request. browser;
String Str =   " Type: "   + Browser. Type +   " <Br/> "
+   " Name: "   + Browser. Browser +   " <Br/> "
+   " Version: "   + Browser. Version +   " <Br/> "
+   " Platform: "   + Browser. Platform;
This . Label2.text = STR; // On the aspx page, you can set its title from the post code because it has runat = server statements.
This. Page. header. Title = "browser detection ";
}

 

 

It's very simple and there's no technology at all. Don't laugh!
