DropDownList绑定 [英] DropDownList Bind

问题描述

大家好.

我有问题.我有一个网格视图，其中放置了下拉列表.现在我想在其他索引的选定索引更改处将项目添加到一个drpdwnlist中.我的问题是我无法获得该特定的下拉列表
在第一个下拉列表的选定索引更改处..任何想法都可以帮助我感到非常困惑.我已将其绑定.但是还有另一个问题，请看一下选定索引更改中的代码.
受保护的void DropDownList2_SelectedIndexChanged(对象发送者，EventArgs e)
{
DropDownList ddl =发送者为DropDownList;
字符串BuildingName = ddl.SelectedItem.Text;
Int32 buildid = objbuilding.slect_bid_for_floor(BuildingName);
数据集dsss = OBJFLOOR.FloorId_Acc_Building(buildid);
//int index = Convert.ToInt32(GridView1.SelectedRow.RowIndex);
//DropDownList ddlg =(DropDownList)(GridView1.SelectedRow.FindControl("DrpFloor"));
//控制gridrow = GridView1.Rows;
GridViewRow rr = GridView1.SelectedRow;
foreach(在GridView1.Rows中控制网格行)
{
DropDownList ddlg =(DropDownList)gridrow.FindControl("DrpFloor");

ddlg.DataSource = dsss.Tables [0];
ddlg.DataTextField ="Floor_Name";
ddlg.DataValueField ="Fid";
ddlg.DataBind();
ddlg.Items.Insert(0，new ListItem("Select"，"-1"));
}
//DropDownList ddlg =(DropDownList)(GridView1.FindControl("DrpFloor"));

}

现在我的DropDown已绑定，但这绑定了所有DropDowm.我在网格视图中创建了Dyanamic行，我想单独绑定每个DropDown请让我知道...有这么多Gr8编程器没有人知道Sol ....

推荐答案

只需让父代获取导致事件的行，然后找到下拉列表

Just get parent to get the row which caused the event and then find drop down

GridViewRow gvrow = (GridViewRow)((DropDownList)(sender)).NamingContainer;
