DropDownList、ListControl、RadioButtonList绑定

一、DropDownList绑定（自己做了测试验证没问题）

namespace NUCTechnologyPark
{
public partial class CeShi : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindMenu();
}

}
public void BindMenu()
{

ListItem list = new ListItem();
list.Text = "请选择新闻类别";
list.Value = "0";
list.Enabled = true;
list.Selected = true;
DropDownList1.Items.Add(list);
DataTable dt = B_News.GetClassNameList(111);
//BindingUtils bind1 = new BindingUtils();
//bind1.BindListControl(dt, DropDownList1, "Menu_Pk", "Class_Name");
for (int i = 0; i < dt.Rows.Count; i++)
{
DataRow dr = dt.Rows[i];
ListItem list1 = new ListItem();
list1.Text = dr["Class_Name"].ToString();
list1.Value = dr["Menu_Pk"].ToString();
list1.Enabled = true;
list1.Selected = false;
DropDownList1.Items.Add(list1);
}
}
//DropDownList选择事件
protected void SelectIndexChanged_Click(object sender, EventArgs e)
{
this.Label1.Text = DropDownList1.SelectedValue;
}

protected void Submit_Click(object sender, EventArgs e)
{
if (this.DropDownList1.SelectedValue == "0")
{
MessageBox.Alter("请选择新闻类别","CeShi.aspx");
}
}
}
}

二、RadioButtonList绑定

DataTable dt = B_Storage.StorageList();
BindingUtils bind = new BindingUtils();
bind.BindListControl(dt, RadioButtonList1, "CIndex", "CName")；

/// <summary>
/// 提供用来绑定所有列表形式控件的方法，如：CheckBoxList、DropDownList、ListBox 、RadioButtonList 类
/// </summary>
/// <param name="dt">要绑定的DataTable</param>
/// <param name="ListControl1">要绑定的列表控件</param>
/// <param name="DataValueField">各列项对应的数据字段</param>
/// <param name="DataTextField">各列项对应的文本字段</param>
public void BindListControl(DataTable dt, ListControl ListControl1, string DataValueField, string DataTextField)
{
if (dt.Rows.Count > 0)
{
ListControl1.DataValueField = DataValueField;
ListControl1.DataTextField = DataTextField;
ListControl1.DataSource = dt;
ListControl1.DataBind();
}
}
