asp.net Checbox在GridView中的应用实例分析

本文实例讲述了asp.net Checbox在GridView中的应用方法。分享给大家供大家参考，具体如下：

先看效果图：

前台代码：样式自己定义哦！

<div style="text-align: center; width: 80%"> <yxy:HkrGridView ID="tabGridView1" runat="server" AutoGenerateColumns="False" Width="100%" OnRowDataBound="HkrGridView1_RowDataBound" OnRowCreated="HkrGridView1_RowCreated" ShowHeader="True" AllowPaging="false" DataKeyNames="keyId" ShowFooter="false"> <Columns> <asp:BoundField> <ItemStyle HorizontalAlign="Center" Width="5%" /> </asp:BoundField> <asp:TemplateField> <ItemTemplate> <a href="<%#DataBinder.Eval（Container.DataItem,"newName"）%>" ><%#DataBinder.Eval（Container.DataItem,"oldName"）%></a> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="memo"> <ItemStyle Width="20%" HorizontalAlign="left" /> </asp:BoundField> <asp:TemplateField> <ItemTemplate> <asp:CheckBox ID="CheckBox" runat="server" /> </ItemTemplate> <ItemStyle HorizontalAlign="Center" Width="5%" /> </asp:TemplateField> </Columns> <FooterStyle ForeColor="Red" HorizontalAlign="Center" Font-Bold="true" /> </yxy:HkrGridView> <div id="DivOne" style="text-align: right"> <asp:CheckBox ID="CheckBoxAll" runat="server" Text="全选" Width="80px" AutoPostBack="True" OnCheckedChanged="CheckBoxAll_CheckedChanged" /> <asp:CheckBox ID="CheckBox1" runat="server" Text="反选" Width="80px" AutoPostBack="True" OnCheckedChanged="CheckBox1_CheckedChanged" /> <asp:Button ID="Button1" runat="server" Text="取 消" CssClass="Button" OnClick="Button1_Click" /> </div></div>

后台代码：

protected void HkrGridView1_RowCreated（object sender, GridViewRowEventArgs e）{if （e.Row.RowType == DataControlRowType.Header）{TableCellCollection tcHeader = e.Row.Cells;tcHeader.Clear（）;//第一行表头tcHeader.Add（new TableHeaderCell（））;tcHeader[0].Text = "序号<BR>No.";tcHeader.Add（new TableHeaderCell（））;tcHeader[1].Text = "附件名称";tcHeader.Add（new TableHeaderCell（））;tcHeader[2].Text = "备注";tcHeader.Add（new TableHeaderCell（））;tcHeader[3].Text = "选择</tr>";}}protected void HkrGridView1_RowDataBound（object sender, GridViewRowEventArgs e）{GridViewRow gr = e.Row;if （e.Row.RowIndex ！= -1）{e.Row.Cells[0].Text = （e.Row.RowIndex + 1）.ToString（）;}}private void HkrGridViewBind（）{string strSql = "SELECT keyId,newName, oldName, localHome,memo FROM aq_file_up WHERE （relaid = @relaid） AND （fjType = @fjType） AND （usestatus = 1）";SqlParameter[] sps = {new SqlParameter（"@relaid",this.hdnRelaId.Value）,new SqlParameter（"@fjType",this.hdnFjType.Value） };DataTable dt = pms.SqlHelper.ExecuteDataTable（CommandType.Text, strSql, sps）;tabGridView1.DataSource = dt;tabGridView1.DataBind（）;}rotected void Button1_Click（object sender, EventArgs e）{CheckBoxAll.Checked = false;CheckBox1.Checked = false;for （int i = 0; i <= tabGridView1.Rows.Count - 1; i++）{CheckBox cb = （CheckBox）tabGridView1.Rows[i].FindControl（"CheckBox"）;cb.Checked = false;}}protected void CheckBox1_CheckedChanged（object sender, EventArgs e）{ for （int i = 0; i <= tabGridView1.Rows.Count - 1; i++）{CheckBox cb = （CheckBox）tabGridView1.Rows[i].FindControl（"CheckBox"）;if （cb.Checked == false）{cb.Checked = true;}else{cb.Checked = false;}}//CheckBox1.Checked =true;CheckBoxAll.Checked = false;}protected void CheckBoxAll_CheckedChanged（object sender, EventArgs e）{ for （int i = 0; i <= tabGridView1.Rows.Count - 1; i++）{CheckBox cb = （CheckBox）tabGridView1.Rows[i].FindControl（"CheckBox"）;if （CheckBoxAll.Checked == true）{cb.Checked = true;}else{cb.Checked = false;}}CheckBox1.Checked = false;}
