分页与查询 关于gridview

引用第三方控件

引入AspNetPager.dll分页文件添加到bin目录下

在引用页中注册

<%@ Register Assembly="AspNetPager" Namespace="Wuqi.Webdiyer" TagPrefix="webdiyer" %>

在引用页中应用控件

<webdiyer:AspNetPager ID="AspNetPager1" runat="server" HorizontalAlign="center" OnPageChanged="AspNetPager1_PageChanged"

OnPageChanging="AspNetPager1_PageChanging" PageSize="15" Width="100%">

</webdiyer:AspNetPager>

查询控件如下：

<td style="height:100%; border: 1px solid #B5C3EF" valign="top" nowrap="">

<table>

<tr valign="top">

<td>查询条件：

<asp:DropDownList

ID="ddlQueryType" runat="server" Width="83px">

<asp:ListItem Value="StatutoryAgent" Selected="True">法人代表</asp:ListItem>

<asp:ListItem Value="RegistCapital">注册资本</asp:ListItem>

<asp:ListItem Value="SetupTime">注册时间</asp:ListItem>

</asp:DropDownList>

<asp:DropDownList ID="DDLFilter" runat="server" Width="51px">

<asp:ListItem Value="like">包含</asp:ListItem>

<asp:ListItem Value=">">大于</asp:ListItem>

<asp:ListItem Value="<">小于</asp:ListItem>

<asp:ListItem Value="=">等于</asp:ListItem>

</asp:DropDownList> 

</td>

<td><mc:DropDownCalendar ID="DDCSetupTime" runat="server" BorderStyle="Inset" BorderWidth="1px">

<WeekendDayStyle BackColor="#C0FFFF" ForeColor="Brown" />

<TitleStyle BackColor="#C00000" ForeColor="White" />

<DayHeaderStyle BackColor="#C0C0FF" />

<DateStyle BackColor="#FFFFC0" />

</mc:DropDownCalendar>

</td>

<td>  <asp:TextBox ID="txtQueryValue" runat="server" CssClass="DownTextBox" Width="172px"></asp:TextBox></td>

<td><asp:Button ID="btnSearch" runat="server" CssClass="blueButtonCss" Text="查 询" Width="61px" OnClick="btnSearch_Click" /></td>

</tr>

</table>

</td>

托一gridview控件

代码如下：

<asp:GridView ID="GVShareHolder" SkinID="GridView8" Width="100%" runat="server" CellPadding="4" ForeColor="#333333" GridLines="None" DataKeyNames="SID" AutoGenerateColumns="False" OnRowDeleting="GVShareHolder_RowDeleting">

<Columns>

<asp:BoundField DataField="SID" HeaderText='<%$ Resources:Companys,SID %>' />

<asp:TemplateField HeaderText='<%$ Resources:Companys,gvshopCardID %>' >

<ItemTemplate>

<asp:HyperLink ID="HyperLinkCardID" runat="server" NavigateUrl='<%# "javascript:OpenWindow(\"/_layouts/GSEGC/Law/GetShopCard.aspx?o=View&sid="+Eval("SID").ToString()+"\");" %>' Text='<%# Bind("CardID") %>' onmouseover="TagToTip('T2TBalloon', BALLOON, true, FADEIN, 400, FADEOUT, 400, ABOVE,true, WIDTH, 260, PADDING, 8, TEXTALIGN, 'left', OFFSETX, -10)" />

<span id="T2TBalloon" style="display:none"><%= Resources.Companys.ShopRunScope %><b><%# Eval("RunScope") + "\n\t"%></b><br /><%=Resources.Companys.ShopPlace %><b><%# Eval("Place")%></b> </span>

</ItemTemplate>

</asp:TemplateField>

<asp:BoundField DataField="RegistCapital" HeaderText='<%$ Resources:Companys,gvShopRegistCapital %>' />

<asp:TemplateField HeaderText='<%$ Resources:Companys,gvshopStatutoryAgent %>'>

<ItemTemplate>

<asp:Label ID="Label1" runat="server" Text='<%# Eval("StatutoryAgent") %>' ></asp:Label>

</ItemTemplate>

</asp:TemplateField>

<asp:BoundField DataField="SetupTime" HeaderText='<%$ Resources:Companys,gvShopSetupTime %>' />

<asp:TemplateField ShowHeader="False">

<ItemTemplate>

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "javascript:OpenWindow(\"/_layouts/GSEGC/Law/GetShopCard.aspx?o=View&sid="+Eval("SID").ToString()+"\");" %>'>

<%=Resources.Companys.select %></asp:HyperLink>

 <asp:HyperLink ID="HyperLink2" runat="server" NavigateUrl='<%# "javascript:OpenWindow(\"/_layouts/GSEGC/Law/GetShopCard.aspx?o=Edit&sid="+Eval("SID").ToString()+"\");" %>'>

<%=Resources.Companys.btnUpdate %></asp:HyperLink>

 <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Delete" OnClientClick="return confirm('确定要删除吗？');">

<%=Resources.Companys.btnDelete %></asp:LinkButton>

</ItemTemplate>

</asp:TemplateField>

<asp:TemplateField ShowHeader="False">

<ItemTemplate>

</ItemTemplate>

</asp:TemplateField>

</Columns>

<FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />

<RowStyle BackColor="#F7F6F3" ForeColor="#333333" />

<EditRowStyle BackColor="#999999" />

<SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />

<PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />

<HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />

<AlternatingRowStyle BackColor="White" ForeColor="#284775" />

</asp:GridView>

添加AspNetPager1_PageChanged代码：

protected void AspNetPager1_PageChanged(object src, EventArgs e)

{

try

{

if (this.txtQueryValue.Text == "")

{

AspNetPager1.RecordCount = ShopCardInfo.GetShopCardCount();

GVShareHolder.DataSource = ShopCardInfo.GetPagedLaw_ShopCard(this.AspNetPager1.StartRecordIndex, this.AspNetPager1.PageSize);

GVShareHolder.DataBind();

}

else

{

GetFilterData();

}

}

catch (Exception)

{

throw;

}

}

添加AspNetPager1_PageChanging代码：

protected void AspNetPager1_PageChanging(object src, Wuqi.Webdiyer.PageChangingEventArgs e)

{

this.LabShowPage.Visible = true;

LabShowPage.Text = (string)base.GetGlobalResourceObject("Companys", "cur") + " " + e.NewPageIndex;

}

定义查询函数GetFilterData()如下：

private void GetFilterData()

{

try

{

string filterStr = string.Empty;

int lastNum = this.AspNetPager1.StartRecordIndex + this.AspNetPager1.PageSize;

if (this.ddlQueryType.SelectedValue.Trim() == "RegistCapital")

{

filterStr = this.ddlQueryType.SelectedValue.Trim() + this.DDLFilter.SelectedValue.Trim() + "'" + float.Parse(this.txtQueryValue.Text.ToString()) + "'";

}

else if (this.ddlQueryType.SelectedValue.Trim() == "StatutoryAgent")

{

filterStr = this.ddlQueryType.SelectedValue.Trim() + this.DDLFilter.SelectedValue.Trim() + "'" + this.txtQueryValue.Text.ToString() + "'";

}

else if (this.ddlQueryType.SelectedValue.Trim() == "SetupTime")

{

this.txtQueryValue.Enabled = false;

filterStr = this.ddlQueryType.SelectedValue.Trim() + this.DDLFilter.SelectedValue.Trim() + "'" + this.DDCSetupTime.Value.ToString() + "'";

this.txtQueryValue.Enabled = true;

}

DataTable dt = ShopCardInfo.GetPageSizeVisited(filterStr);

DataView dv = dt.DefaultView;

dv.RowFilter = "RowNumber >= " + this.AspNetPager1.StartRecordIndex.ToString() + " and RowNumber <= " + lastNum.ToString();

this.AspNetPager1.RecordCount = dt.Rows.Count;

this.GVShareHolder.DataSource = dv;

this.GVShareHolder.DataBind();

}

catch (Exception)

{

throw;

}

}

查询按钮事件如下：

protected void btnSearch_Click(object sender, EventArgs e)

{

try

{

if (this.txtQueryValue.Text.ToString() == "" && this.ddlQueryType.SelectedValue.Trim() != "SetupTime")

{

AspNetPager1.RecordCount = ShopCardInfo.GetShopCardCount();

GVShareHolder.DataSource = ShopCardInfo.GetPagedLaw_ShopCard(this.AspNetPager1.StartRecordIndex, this.AspNetPager1.PageSize);

GVShareHolder.DataBind();

}

else

{

GetFilterData();

}

}

catch (Exception)

{

throw;

}

}

分页存储过程

ALTER PROCEDURE [dbo].PageLaw_ShopCard

(

@startIndex INT,

@pageSize INT

)

AS

declare @Tab nvarchar(50)

declare @sql varchar(200)

set @sql = 'WITH tablelist AS (SELECT ROW_NUMBER() OVER (ORDER BY Tmp.SID DESC) AS Row, * from Law_ShopCard as Tmp)

SELECT * FROM tablelist WHERE Row between '+cast(@startIndex as varchar(20)) +' and '+ cast(@startIndex + @pageSize -1 as varchar(20))

begin

exec (@sql)

print @sql

end
