问题描述

一个DropDownList中的选定值转发器???

Hi guys,


how to do:
Selected value on a DropDownList inside of a repeater???

推荐答案

尝试这种方式可能是它可以工作如果没有然后写你想要实现的正确



DateTime dt = Convert.ToDateTime（Request.QueryString [VehicleTrackingDate]）;

SqlParameter [] Param = new SqlParameter [1];

Param [0] = new SqlParameter（@ DateAsOf，dt）;

Repeater1.DataSource = DAL.GetDataWithParameters（Sp_GetVehicleTrackingOnDate，Param）;

Repeater1.DataBind （）;



for（int i = 0; i< = Repeter1.Items.Count-1; i ++）

{

//((DropDownList)dataItem.FindControl(\"ddldept\")).SelectedValue = true;

DropDownList drp =（DropDownList）Repeater1.Items [i] .FindControl（ddldept）;

drp.SelectedValue = true;

}



感谢你!!

Try on this Way may Be its can working if not then Write proper that u want to implement

DateTime dt = Convert.ToDateTime(Request.QueryString["VehicleTrackingDate"]);
SqlParameter[] Param = new SqlParameter[1];
Param[0] = new SqlParameter("@DateAsOf", dt);
Repeater1.DataSource = DAL.GetDataWithParameters("Sp_GetVehicleTrackingOnDate", Param);
Repeater1.DataBind();

for (int i=0;i<=Repeter1.Items.Count-1;i++)
{
//((DropDownList)dataItem.FindControl("ddldept")).SelectedValue = true;
DropDownList drp=(DropDownList)Repeater1.Items[i].FindControl("ddldept");
drp.SelectedValue = true;
}

Thanking You!!

          int count = Repeater1.Items.Count;
          int index = 0;
          string cID = d.UniqueID;
