Sometimes we need to modify the font, color, size, and other items of our controls. At the same time, I also want to load the system's font list and color list in listeitem.
First create our file
Default2.aspx
<% @ Page Language = "C #" autoeventwireup = "true" codefile = "default2.aspx. cs" inherits = "default2" %>
<! Doctype HTML public "-// W3C // dtd xhtml 1.0 transitional // en" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<HTML xmlns = "http://www.w3.org/1999/xhtml">
<Head runat = "server">
<Title> untitled page </title>
</Head>
<Body>
<Form ID = "form1" runat = "server">
<Div>
Select the background color <br/>
<Asp: dropdownlist id = "listbackcolor" runat = "server" width = "168px">
</ASP: dropdownlist> <br/>
<Br/>
Select font <br/>
<Asp: dropdownlist id = "lstfontname" runat = "server" width = "168px">
</ASP: dropdownlist> <br/>
<Br/>
Font size <br/>
<Asp: textbox id = "textbox1" runat = "server"> </ASP: textbox> <br/>
<Br/>
Border style <br/>
<Asp: radiobuttonlist id = "radiobuttonlist1" runat = "server">
</ASP: radiobuttonlist> </div>
<Br/>
<Br/>
<Asp: checkbox id = "chkpic" runat = "server" text = "use default image"/> <br/>
<Br/>
What to say <br/>
<Asp: textbox id = "textbox2" runat = "server" Height = "101px" textmode = "multiline" width = "192px"> </ASP: textbox> <br/>
<Br/>
<Asp: button id = "cmdupdate" runat = "server" text = "selected" onclick = "cmdupdate_click"/> <br/>
<Br/>
<Br/>
<Asp: Panel id = "pnlcard" runat = "server" Height = "70px" width = "476px">
<Br/>
<Asp: Label id = "lblgreeting" runat = "server" text = "label"> </ASP: Label> <br/>
<Br/>
<Asp: Image id = "imgdefault" runat = "server"/> </ASP: Panel>
<Br/>
<Br/>
</Form>
</Body>
</Html>
Default2.aspx. CS
Using system;
Public partial class default2: system. Web. UI. Page
{
Protected void page_load (Object sender, eventargs E)
{
}
Protected void cmdupdate_click (Object sender, eventargs E)
{
}
}
Conventional cooking is to add content one by one in listitem. Then, in cmdupdate_click
Use
// Update the color
Pnlcard. backcolor = color. fromname (lstbackcolor. selecteditem. Text );
// Update the font
Lblgreeting. Font. Name = lstfontname. selecteditem. text;
// Set the font size
Lblgreeting. Font. size = fontunit. Point (int32.parse (textfontsize. Text ));
// Update the Border Width
Int bodervalue = int32.parse (lstborder. selecteditem. Value ):
Pnlcard. borderstyle = (borderstyle) bordervalue;
Another more systematic update Method
1. Obtain the list of all fonts installed.
System. Drawing. Text. installedfontcollection fonts;
Fonts = new system. Drawing. Text. installedfontcollection ();
Foreach (fontfamily family in fonts. Families)
{
Lstfontname. Items. Add (family. Name );
}
2. Get all installed colors
String [] colorarray = enum. getnames (typeof (system. Drawing. knowncolor ));
Lstbackcolor. datasource = colorarray;
Lstbackcolor. databind ();
3. The same is true for borderstyle.
String [] borderstylearray = enum. getnames (typeof (borderstyle ));
Lstborder. datasource = borderstylearray;
Lstborder. databind ();
