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();

foreach (RepeaterItem dataItem in Repeater1.Items)
{
((DropDownList)dataItem.FindControl("ddldept")).SelectedValue = true;
}

C#

protected void myRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item ||
       e.Item.ItemType == ListItemType.AlternatingItem)
    {
        var degree_dropdown = e.Item.FindControl("degree_dropdown") as DropDownList;
        string degreeCode = (string) ((DataRowView) e.Item.DataItem)["degreeCode"];

        if (degree_dropdown != null)
        {
            degree_dropdown.DataSource = degrees; //a datatable
            degree_dropdown.DataTextField = "degree";
            degree_dropdown.DataValueField = "code";
            degree_dropdown.DataBind();

            if (degree_dropdown.Items.FindByValue(degreeCode) != null)
                degree_dropdown.SelectedValue = degreeCode;
        }
