.cs 里怎么给ascx里的控件设置选中项

[dys_198102]

ascx代码

public partial class Pub_Input_Banks : System.Web.UI.UserControl
{
protected System.Web.UI.WebControls.DropDownList PB_;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
GetBanks();
}
}
protected string _value = "";
public string GetSelectBanksValue
{
get { return this.Pub_Banks_.SelectedValue; }
set { _value = value;

try
{
this.Pub_Banks_.Items.FindByValue(_value.ToString()).Selected = true;
}
catch
{ }
}



}
//public string SetSelectBanksValueSelected
//{
// set { this.Pub_Banks_.Items.FindByValue(value.ToString()).Selected = true; }
//}
/// <summary>
/// 获取银行相关数据
/// </summary>
protected void GetBanks()
{
string sql = "SELECT banks_name FROM banks ", code = "";

this.Pub_Banks_.Items.Add(new ListItem("--All--", "t"));
if (Cache["Pub_Banks"] != null)
{
DataSet ds1 = (DataSet)Cache["Pub_Banks"]; //从内存中获取数据
foreach (DataRow dr in ds1.Tables[0].Rows)
{
code = dr["banks_name"].ToString();
this.Pub_Banks_.Items.Add(new ListItem(code, code));
}
}
else
{
DataSet set = WebData1.dataSet(sql);

Cache.Insert("Pub_Banks", set, null, DateTime.Now.AddHours(0.1), TimeSpan.Zero); //将数据保存到内存

foreach (DataRow dr in set.Tables[0].Rows)
{
code = dr["banks_name"].ToString();
this.Pub_Banks_.Items.Add(new ListItem(code, code));
}
}

}
}

.cs代码
protected void Button1_Click(object sender, EventArgs e)
{
string banks="招商";

//this.Pub_Banks.SetSelectBanksValueSelected(); //这里怎么弄，高人指点
{

再问一点： .cs代码 protected void Button1_Click(object sender, EventArgs e) { string banks="招商"; this.Pub_Banks.BanksValue=banks; //怎么在这里怎么设.Disabled = true; ｝

[IE11下面经常卡到爆]

public string BanksValue
{
      get { return this.Pub_Banks_.SelectedValue; }
      set {
               if(value == null) throw new ArgumentNullException("value");
               var item = this.Pub_Banks_.Items.FindByValue(value);
               if(item != null) item.Selected = true;      
        }
    }

protected void Button1_Click(object sender, EventArgs e)
 {
        string banks="招商"; 
        this.BanksValue = banks;
        this.Pub_Banks.Disabled = true;
 ｝
