How to realize GridView pagination
This article is about how to implement GridView pagination. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.
To add to the GridView
/ / implement paging
AllowPaging= "true"
/ / 10 rows per page of data
PageSize= "10"
/ / events triggered during paging
OnPageIndexChanging= "gvwDesignationName_PageIndexChanging"
In server events
The copy code is as follows:
Protectedvoid gvwDesignationName_PageIndexChanging (object sender, GridViewPageEventArgs e)
{
GvwDesignationName.PageIndex=e.newIndex
BingDesignatioonName ()
}
Here I give a general template for displaying paging (search on the Internet, give your own comments)
The copy code is as follows:
Current No.:
/ / ((GridView) Container.NamingContainer) is to get the current control
Page / Total:
/ / get the total number of paged pages
Page
/ / if the page is the first page, then the link will not be displayed. At the same time, it corresponds to the command parameter CommandArgument with its own identification.
Home page
Previous page
/ / if the page is the end of the page, then the connection will not be displayed
next page
Last page
Go to th
Page
/ / CommandArgument here, even if you click the button, the e.newIndex value is 3.
The code in the event is
The copy code is as follows:
Protected void gvwDesignationName_PageIndexChanging (object sender, GridViewPageEventArgs e)
{
/ / get the control
GridView theGrid = sender as GridView
Int newPageIndex = 0
If (e.NewPageIndex==-3)
{
/ / clicked the Go button
TextBox txtNewPageIndex = null
/ / GridView provides more API than DataGrid. You can use BottomPagerRow or TopPagerRow to get paging blocks. Of course, HeaderRow and FooterRow are also added.
GridViewRow pagerRow = theGrid.BottomPagerRow
If (pagerRow! = null)
{
/ / get the text control
TxtNewPageIndex = pagerRow.FindControl ("txtNewPageIndex") as TextBox
}
If (txtNewPageIndexpositions = null)
{
/ / get the index
NewPageIndex = int.Parse (txtNewPageIndex.Text)-1
}
}
Else
{
/ / clicked on other buttons
NewPageIndex = e.NewPageIndex
}
/ / prevent new index from overflowing
NewPageIndex = newPageIndex
< 0 ? 0 : newPageIndex; newPageIndex = newPageIndex >= theGrid.PageCount? TheGrid.PageCount-1: newPageIndex
/ / get a new value
TheGrid.PageIndex = newPageIndex
/ / rebind
BingDesignatioonName ()
}
