ASP.NET 完美解决checkbox多选传值以及相关操作

小项目要用到多选，修改相关数据记录：

效果如下：



具体实现如下：

用到了GridView控件。

---------------------------------------------------------------------------------------------------------------------------------------

GridView是一个提供相关数据库操作的控件，MSDN解释：猛击此处

---------------------------------------------------------------------------------------------------------------------------------------

具体操作如下：

a.aspx关键代码：

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
BorderWidth="0px" Width="701px" ForeColor="Blue" Height="182px">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1"  runat="server" />
<asp:HiddenField ID="HidID" runat="server" Value='<%# Bind("id") %> ' />
<asp:Label  ID="Label1" runat="server" style="font-size:12px;color:#3344ff"  Text='<%# Bind("content") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

b.aspx后台关键代码：（按钮触发）

//给GridView绑定数值
public void bind()
{
string sql;
sql = "select id, content from intro";
GridView1.DataSource = access.GreatDs(sql);
GridView1.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
int rowCount = GridView1.Rows.Count;
string str = ConfigurationManager.ConnectionStrings["kuny"].ConnectionString;
OleDbConnection conn = new OleDbConnection(str);
conn.Open();
int tag = 0;
for (int i = 0; i < rowCount; i++)
{
CheckBox tempChk = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
HiddenField HidID = (HiddenField)GridView1.Rows[i].FindControl("HidID");
if (tempChk.Checked == true)
{
string update_exam_item = "update baoming_info set bk_exerm_id" + HidID.Value + "=" + "1" + " where bk_exer_id=" + Session["StuID"];
//alert(update_exam_item);
OleDbCommand cmd = new OleDbCommand(update_exam_item, conn);
cmd.ExecuteNonQuery();
tag++;
}

}
if (tag == 0)
{
alert("您至少需要选择一项考试项目！");
}
else
{
conn.Close();
Response.Redirect("step_1.aspx");
}

}

总结：

for (int i = 0; i < rowCount; i++)
{
　　　　　　　//遍历取checkbox以及隐藏text的值
CheckBox tempChk = (CheckBox)GridView1.Rows[i].FindControl("CheckBox1");
HiddenField HidID = (HiddenField)GridView1.Rows[i].FindControl("HidID");
　　　　　　 //
if (tempChk.Checked == true)
{
string update_exam_item = "update baoming_info set bk_exerm_id" + HidID.Value + "=" + "1" + " where bk_exer_id=" + Session["StuID"];
//alert(update_exam_item);
OleDbCommand cmd = new OleDbCommand(update_exam_item, conn);
cmd.ExecuteNonQuery();
tag++;
}

}
总结下，先要用GridView控件，并为它绑定数据源bind(),在gridview的属性TemplateField、ItemTemplate添加相应的checkbox等，再用button事件触发，进行相关操作
