哦，那很简单。只需选择三个预期列，然后组合成一个字符串并返回为一列。然后就像简单的下拉列表一样绑定返回列。





示例代码：

Oh then it''s easy.just select three expected column and then combine into one string and return as one column.then just bind the returning column as like as simple drop down list.


Sample Code:

List<ListItem> users = new List<ListItem>();
foreach (SubscriptionUser su in subscriptionDetails.UserList)
{
    users.Add(new ListItem(su.FirstName + " " + su.LastName, su.EmailAddress));
}
ddlPrimaryContact.DataTextField = "Text";
ddlPrimaryContact.DataValueField = "Value";
ddlPrimaryContact.DataSource = users;
ddlPrimaryContact.DataBind();

希望这可以帮助



datatable dt = new datatable（）;

dt = filldata（）; //填写dt的任何方法



CMB.DataTextField =Text feild;

CMB.DataValueField =value feild;

CMB.datasourse = dt;

CMB.databind（）;

wish this can help

datatable dt = new datatable();
dt = filldata(); // any method to fill dt

CMB.DataTextField ="Text feild";
CMB.DataValueField = "value feild ";
CMB.datasourse= dt ;
CMB.databind();
