获取DropDownList控件的ID

[zjy1985cool]

this.DDLType.DataValueField = "ClassTypeID";
ID放这里了 是GUID 我想读出来怎么弄

public void DropDownListBind()
{
using (OfficeChannel.OfficeChannelDataContext MyCon = new OfficeChannel.OfficeChannelDataContext(ConfigurationManager.ConnectionStrings["OfficeChannelConnectionString_Web"].ConnectionString))
{
var linqTxt = from i in MyCon.Class_Type
select new
{
ClassTypeID = i.classTypeID,
ClassType = i.classType,
};
this.DDLType.DataSource = linqTxt;
this.DDLType.DataTextField = "ClassType";
this.DDLType.DataValueField = "ClassTypeID";
this.DDLType.DataBind();
}
}
protected void DDLType_SelectedIndexChanged(object sender, EventArgs e)
{
using (OfficeChannel.OfficeChannelDataContext MyCon = new OfficeChannel.OfficeChannelDataContext(ConfigurationManager.ConnectionStrings["OfficeChannelConnectionString_Web"].ConnectionString))
{
Guid newID = new Guid();//获取ID怎么写 我写的是this.DDLType.DataValueField报错了
var linqTxt = (from i in MyCon.Class
from itype in MyCon.Class_Type
where i.classTypeID == itype.classTypeID && i.classTypeID== newID
select new
{
PubTime = i.releaseTime,
Title = i.classTitle,
Author = Convert.ToString(i.Class_Author.authorName),
ClassType = itype.classType
}).Take(10);
DataList1.DataSource = linqTxt;
DataList1.DataBind();
}
}
