给你一个例子，参考一下
private bool InitCol()
{
try
{
ArrayList values = new ArrayList();
values.Add(new PositionColData("部门","bmmc"));
values.Add(new PositionColData("申请日期","apply_time"));
values.Add(new PositionColData("申请发车时间","apply_start_time"));
values.Add(new PositionColData("计划回车时间","apply_end_time"));
values.Add(new PositionColData("起止地点","start_address"));
values.Add(new PositionColData("用车事由","usecar_cause"));
values.Add(new PositionColData("用车人数","usecar_count"));
values.Add(new PositionColData("用车人","connection_name"));
values.Add(new PositionColData("车辆","car"));
values.Add(new PositionColData("调配驾驶员编号","driver_id"));
values.Add(new PositionColData("车辆出车时间","go_time"));
values.Add(new PositionColData("车辆回车时间","back_time"));
values.Add(new PositionColData("加班时间","overtime"));
values.Add(new PositionColData("是否长途用车","long_flag"));
this.ColList.DataSource=values;
this.ColList.DataTextField="FieldName";
this.ColList.DataValueField="FieldValue";
this.ColList.DataBind();
return true;
}
catch(Exception ex)
{
Response.Write("<script language =javascript > alert('"+ex.Message.ToString()+"');</script>");
return false;
}
}
/// <summary>
/// 配置列数据类
/// </summary>
public class PositionColData
{
private string _FieldName;
private string _FieldValue;
public PositionColData(string _name,string _value)
{
_FieldName=_name;
_FieldValue=_value;
}
public string FieldName
{
get {return _FieldName;}
}
public string FieldValue
{
get {return _FieldValue;}
}
}
