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>

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");

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();

}
