Question

我在GRIDVIEW的FOOTERROW添加了一个DropDownList(ID DropDownList1),请问我如何在后台获取这个DropDownList并给它赋初值?从数据库表中查询值添入DropDownList的ITEMS中
我试过DropDownList ddl=(DropDownList)GridView1.FooterRow.FindControl("DropDownList1");
ddl.Items.Add("dsdf");
但是添加不进去,

Answer 1

if (e.Item.ItemType == ListItemType.Footer)
{
  DropDownList ddl=(DropDownList)GridView1.FooterRow.FindControl("DropDownList1");
ddl.Items.Add("dsdf");}
要在ItemDataBound绑定列事件里写

Answer 2

ItemDataBound
if (e.Item.ItemType == ListItemType.Footer)ls基本正确

Answer 3

DropDownList ddl = GridView1.FooterRow.FindControl("DropDownList1") as DropDownList;  // 获取控件
ddl.DataSource = dataTable;
ddl.DataBind();

Answer 4

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
  if (e.Item.ItemType == ListItemType.Footer)
{
  DropDownList ddl=(DropDownList)e.Row.FindControl("DropDownList1");
ddl.Items.Add("dsdf");}}

Answer 5

//是Row 不是Item
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{ if (e.Row.RowType == DataControlRowType.Footer)
{
DropDownList dropTemp = (DropDownList)e.Row.FindControl("DropDownList1");
                if (dropTemp != null)
                {
                    dropTemp.DataSource = BindDropDownList();//绑定的方法
                    dropTemp.DataTextField = "XXXX";
                    dropTemp.DataTextField = "XXXX";
                    dropTemp.DataBind();                    dropTemp.SelectedIndex = dropTemp.Items.IndexOf(dropTemp.Items.FindByText(yourString));
                } }
}

Answer 6

反正大概就是那个意思
我给他个大体思路  打点出不来Item那就是Row贝

Answer 7

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{ if (e.Row.RowType == DataControlRowType.Footer)
{
DropDownList dropTemp = (DropDownList)e.Row.FindControl("DropDownList1");
                if (dropTemp != null)
                {
                    dropTemp.DataSource = BindDropDownList();//绑定的方法
                    dropTemp.DataTextField = "XXXX";
                    dropTemp.DataTextField = "XXXX";
                    dropTemp.DataBind();                    dropTemp.SelectedIndex = dropTemp.Items.IndexOf(dropTemp.Items.FindByText(yourString));
                } }
}
