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;

}

希望本文所述对大家asp.net程序设计有所帮助。
