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;}
