.net how to implement GridView paging template
This article mainly introduces how to achieve the .net GridView paging template, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.
The code is as follows:
/ / add the following attributes to the GridView (foreground or background depends on your habit.)
/ / implement paging
AllowPaging= "true"
/ / 10 rows per page of data
PageSize= "10"
/ / events triggered during paging
OnPageIndexChanging= "gvwDesignationName_PageIndexChanging"
/ / in the server event
Protected void gvwDesignationName_PageIndexChanging (object sender, GridViewPageEventArgs e)
{
GvwDesignationName.PageIndex=e.newIndex
BingDesignatioonName ()
}
/ / here I give a universal template for displaying paging.
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 corresponding event is
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 ()
}
