Implementation Method and code of asp.net without refreshing pages

I saw a custom page control two days ago. Like AspNetPager, it implements the IPostBackEventHandler interface, but it is much simpler. Can I think that the ICallbackEventHandler interface cannot be implemented without refreshing new pages? When I think of it, I will do it right away. Finally, the idea has become a reality !!
I personally like to use Repeater. Because of its conciseness, this AjaxPager is targeted to Repeater!
Step by step:
Code
The Code is as follows:
[DefaultProperty ("TotalRecord "),
ToolboxData ("<{0}: AjaxPager runat = server> </{0}: AjaxPager>")]
Public class AjaxPager: WebControl, ICallbackEventHandler
{
Public AjaxPager ()
: Base (HtmlTextWriterTag. Div)
{
This. Load + = new EventHandler (AjaxPager_Load );
}
Void AjaxPager_Load (object sender, EventArgs e)
{
String script = "function AjaxPagerCallBack (returnData) {var parts = returnData. split ('[_]'); document. getElementById ('"+ this. uniqueID. replace ('$', '_') + "'). innerHTML = parts [0]; document. getElementById ('"+ Info. containID + "'). innerHTML = parts [1]} ";
This. Page. ClientScript. RegisterClientScriptBlock (this. Page. GetType (), "AjaxPagerCallBack", script, true );
}
}

Here, a piece of JS Code is registered to the page in the Load event. The AjaxPagerCallBack method performs two operations and puts the data presented by itself into the DIV container generated by the client, that is, the id is this. uniqueID. replace ('$', '_') div, ClientID seems OK! Haha, confused for a moment! The second step is to put the paging data in the div with the id Info. ContainID, which will be discussed below the Info Object.
Variable attributes
The Code is as follows:
# Region variable
Private string _ BarBackGroundColor = "# FFFFFF ";
Private string _ BarLinkColor = "Navy ";
Private string _ BarCurrentColor = "# EEEEEE ";
Private int _ TotalRecord = 50;
Private int _ TotalPage = 0;
Private int _ CurrentIndex = 1;
Private int _ ItemSize = 10;
Private PageInfo _ Info = new PageInfo ();
# Endregion
# Region attributes
# Region appearance
[Description ("Page background color "),
Bindable (true ),
Category ("appearance "),
DefaultValue ("# FFFFFF")]
Public string BarBackGroundColor
{
Get {return _ BarBackGroundColor ;}
Set {_ BarBackGroundColor = value ;}
}
[Description ("pagination bar link digit color "),
Bindable (true ),
Category ("appearance "),
DefaultValue ("Navy")]
Public string BarLinkColor
{
Get {return _ BarLinkColor ;}
Set {_ BarLinkColor = value ;}
}
[Description ("number color of the current page of the paging bar "),
Bindable (true ),
Category ("appearance "),
DefaultValue ("# EEEEEE")]
Public string BarCurrentColor
{
Get {return _ BarCurrentColor ;}
Set {_ BarCurrentColor = value ;}
}
# Endregion
# Region Behavior
[Description ("Total number of records "),
Category ("behavior "),
DefaultValue (50)]
Public int TotalRecord
{
Get {return _ TotalRecord ;}
Set
{
_ TotalRecord = value;
}
}
[Description ("Total pages "),
Category ("behavior "),
DefaultValue (0)]
Public int TotalPage
{
Get {return _ TotalPage ;}
}
[Description ("Bar size "),
Category ("behavior "),
DefaultValue (10)]
Public int BarSize
{
Get {return _ ItemSize ;}
Set
{
Foreach (char c in System. Convert. ToString (value ))
{
If (! Char. IsNumber (c ))
{
_ ItemSize = 10;
Break;
}
}
_ ItemSize = value;
}
}
[Description ("Current page value "),
Category ("behavior "),
DefaultValue (1)]
Public int PageIndex
{
Get {return _ CurrentIndex ;}
Set {_ CurrentIndex = value ;}
}
# Endregion
Public PageInfo Info
{
Get {return _ Info ;}
Set {_ Info = value ;}
}
# Endregion
