【问题描述】:
我想在 GridView 中显示员工详细信息。我的客户希望他能够在不单击“编辑”按钮进行更新的情况下更新记录。因此,我将所有内容都保存在 GridView 的 ItemTemplate 字段中。
我的数据库表是: Emp(EmpNo, EName, Sal, DeptNo) 部门(部门编号、部门名称、位置)
因此,我编写了一个 sp 来获取数据:EmpNo、EName、Sal、DeptName
在这里,我想在 DropDownList 中显示 DeptName 字段。这里只有我面临这个问题。 DropDownList 没有填充正确的 DeptName 值,而是第一个字段。
我的代码隐藏如下:
public partial class GvwEmployee : System.Web.UI.Page
{
SqlConnection objConn = new SqlConnection(System.Web.Configuration.WebConfigurationManager.ConnectionStrings["STERIAConnectionString"].ConnectionString);
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
GridView1.DataSource = EmployeeList;
GridView1.DataBind();
}
}
private List<Employee> EmployeeList
{
get{
List<Employee> employeeList = new List<Employee>();
SqlCommand objCmd = new SqlCommand("usp_GetEmpDetails", objConn);
objCmd.CommandType = CommandType.StoredProcedure;
objConn.Open();
SqlDataReader objDR = objCmd.ExecuteReader();
while (objDR.Read())
{
Employee employee = new Employee();
employee.EmpNo = Convert.ToInt32(objDR["EmpNo"]);
employee.EName = Convert.ToString(objDR["EName"]);
employee.Salary = Convert.ToDouble(objDR["Salary"]);
employee.DeptNo = Convert.ToInt32(objDR["DeptNo"]);
employee.DeptName = Convert.ToString(objDR["DeptName"]);
employeeList.Add(employee);
}
objDR.Close();
objConn.Close();
return employeeList;
}
}
private List<Department> DeptList
{
get
{
List<Department> deptList = new List<Department>();
SqlCommand objCmd = new SqlCommand("usp_GetDeptDetails", objConn);
objCmd.CommandType = CommandType.StoredProcedure;
objConn.Open();
SqlDataReader objDR = objCmd.ExecuteReader();
while (objDR.Read())
{
Department dept = new Department();
dept.DeptNo = Convert.ToInt32(objDR["DEPTNO"]);
dept.DName = Convert.ToString(objDR["DNAME"]);
dept.Location = Convert.ToString(objDR["Location"]);
deptList.Add(dept);
}
objDR.Close();
objConn.Close();
return deptList;
}
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList ddlDeptName = e.Row.FindControl("ddlDeptName") as DropDownList;
if (ddlDeptName != null)
{
ddlDeptName.DataSource = DeptList;
ddlDeptName.DataBind();
ddlDeptName.SelectedValue = GridView1.DataKeys[e.Row.RowIndex].Value.ToString();
}
}
if (e.Row.RowType == DataControlRowType.Footer)
{
}
}
}
谁能告诉我问题出在哪里,为什么 DeptName DropDownList 没有填写正确的值?
