GridView中嵌套DropDownList的实现_[Asp.Net教程]
效果图：


后台代码：

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
public partial class Default4 : System.Web.UI.Page
{
SqlConnection sqlcon;
string strCon = "Data Source=(local);Database=北风贸易;Uid=sa;Pwd=sa";
protected void Page_Load(object sender, EventArgs e)
{
DropDownList ddl;
if (!IsPostBack)
{
string sqlstr = "select top 5 * from 飞狐工作室";
sqlcon = new SqlConnection(strCon);
SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon);
DataSet myds = new DataSet();
sqlcon.Open();
myda.Fill(myds, "飞狐工作室");
GridView1.DataSource = myds;
GridView1.DataBind();
for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
{
DataRowView mydrv = myds.Tables["飞狐工作室"].DefaultView[i];
if (Convert.ToString(mydrv["员工性别"]).Trim() == "True")
{
ddl = (DropDownList)GridView1.Rows[i].FindControl("DropDownList1");
ddl.SelectedIndex = 0;
}
if (Convert.ToString(mydrv["员工性别"]).Trim() == "False")
{
ddl = (DropDownList)GridView1.Rows[i].FindControl("DropDownList1");
ddl.SelectedIndex = 1;
}
}
sqlcon.Close();
}
}
public SqlDataReader ddlbind()
{
string sqlstr = "select distinct 员工性别 from 飞狐工作室";
sqlcon = new SqlConnection(strCon);
SqlCommand sqlcom = new SqlCommand(sqlstr, sqlcon);
sqlcon.Open();
return sqlcom.ExecuteReader();
}
前台主要代码：

CellPadding="3" Font-Size="9pt" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px">






’ DataValueField="员工性别" DataTextField="员工性别">
