GridView comes with a paging function implementation

To implement the Grdview paging function
The operation is as follows:
1. Change the AllowPaging property of the Grdview control to True.
2. Change the PageSize property of the Grdview control to any numeric value (default = 10)
3. Change the Pagesetting->mode of the Grdview control to numeric, etc. (the default is numeric) This property is a pagination style.
The GridView property is set, and you can see the pagination style from the page as well.

Now you're starting to implement paging:
1, add after <<asp:gridview id=......>, onpageindexchanging= "gridview1_pageindexchanging"
2, add in the corresponding Aspx.cs:
protected void Gridview1_pageindexchanging (object sender, Gridviewpageeventargs e)
{
Gridview1.pageindex = E.newpageindex;
}
