GridView利用PagerTemplate做分页显示设置上一页下一页转到下拉转页
效果如图：
代码如下：
aspx页：
<asp:GridView ID="GridViewMain" runat="server"
OnPageIndexChanging="GridViewMain_PageIndexChanging"
ondatabound="GridViewMain_DataBound"
PageSize="10">
<PagerTemplate>
<asp:Label ID="lblPage" runat="server" Text='<%# "第" + (((GridView)Container.NamingContainer).PageIndex + 1) + "页/共" + (((GridView)Container.NamingContainer).PageCount) + "页" %> '></asp:Label>
<asp:LinkButton ID="lbnFirst" runat="Server" Text="首页" Enabled='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>' CommandName="Page" CommandArgument="First" ></asp:LinkButton>
<asp:LinkButton ID="lbnPrev" runat="server" Text="上一页" Enabled='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>' CommandName="Page" CommandArgument="Prev" ></asp:LinkButton>
<asp:LinkButton ID="lbnNext" runat="Server" Text="下一页" Enabled='<%# ((GridView)Container.NamingContainer).PageIndex != (((GridView)Container.NamingContainer).PageCount - 1) %>' CommandName="Page" CommandArgument="Next" ></asp:LinkButton>
<asp:LinkButton ID="lbnLast" runat="Server" Text="尾页" Enabled='<%# ((GridView)Container.NamingContainer).PageIndex != (((GridView)Container.NamingContainer).PageCount - 1) %>' CommandName="Page" CommandArgument="Last" ></asp:LinkButton>
到第<asp:dropdownlist id="PageDropDownList"
autopostback="true"
onselectedindexchanged="PageDropDownList_SelectedIndexChanged"
runat="server"/> 页
</PagerTemplate>
cs页
protected void GridViewMain_PageIndexChanging(object sender,GridViewPageEventArgs e)
{
GridViewMain.PageIndex = e.NewPageIndex;
InitListFillData(); //数据绑定
}
protected void PageDropDownList_SelectedIndexChanged(Object sender, EventArgs e)
{
// Retrieve the pager row.
GridViewRow pagerRow = GridViewMain.BottomPagerRow;
// Retrieve the PageDropDownList DropDownList from the bottom pager row.
DropDownList pageList = (DropDownList)pagerRow.Cells[0].FindControl("PageDropDownList");
// Set the PageIndex property to display that page selected by the user.
GridViewMain.PageIndex = pageList.SelectedIndex;
InitListFillData(); //数据绑定
}
protected void GridViewMain_DataBound(Object sender, EventArgs e)
{
GridViewMain.BottomPagerRow.Visible = true;//只有一页数据的时候也再下面显示pagerrow，需要top的再加Top
// Retrieve the pager row.
GridViewRow pagerRow = GridViewMain.BottomPagerRow;
// Retrieve the DropDownList and Label controls from the row.
DropDownList pageList = (DropDownList)pagerRow.Cells[0].FindControl("PageDropDownList");
Label pageLabel = (Label)pagerRow.Cells[0].FindControl("CurrentPageLabel");
if (pageList != null)
{
// Create the values for the DropDownList control based on
// the total number of pages required to display the data
// source.
for (int i = 0; i < GridViewMain.PageCount; i++)
{
// Create a ListItem object to represent a page.
int pageNumber = i + 1;
ListItem item = new ListItem(pageNumber.ToString());
// If the ListItem object matches the currently selected
// page, flag the ListItem object as being selected. Because
// the DropDownList control is recreated each time the pager
// row gets created, this will persist the selected item in
// the DropDownList control.
if (i == GridViewMain.PageIndex)
{
item.Selected = true;
}
// Add the ListItem object to the Items collection of the
// DropDownList.
pageList.Items.Add(item);
}
}
if (pageLabel != null)
{
// Calculate the current page number.
int currentPage = GridViewMain.PageIndex + 1;
// Update the Label control with the current page information.
pageLabel.Text = "Page " + currentPage.ToString() +
" of " + GridViewMain.PageCount.ToString();
}
}
