</asp:GridView>当我点击 ”获取“按钮时 怎么获取  GridView 当前行 DropDownList 控件的值

Answer 1

用Eval()方法绑定一下就行了.

Answer 2

恐怕用Button 下面的一个属性叫CommandName 可以解决这个问题..
先将CommandName = "GetValue"
然后再在GridView里面添加一个RowCommand 事件..
在里面写一个判断语句
if(e.CommandName == "GetValue")
{
   //处理语句
}这样就获取到DropDownList里面的值了...

Answer 3

在RowCommand 事件.. 
怎么获取当 当前行 DropDownList 控件值

Answer 4

不知道是不是要这样的
先设置Button2的CommandName，CommandArgument
DropDownList ddl = (DropDownList)GridView1.Rows[e.CommandArgument].FindControl("DropDownList1");
.....

Answer 5

6楼正解....
DropDownList ddl = (DropDownList)GridView1.Rows[e.CommandArgument].FindControl("DropDownList1");

Answer 6

              <asp:TemplateField>
                    <ItemTemplate>
                        <asp:DropDownList ID="ddl" runat="server" Width="100px">
                            <asp:ListItem>a</asp:ListItem>
                            <asp:ListItem>b</asp:ListItem>
                            <asp:ListItem>c</asp:ListItem>
                        </asp:DropDownList>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Button ID="Button1" runat="server" Text="Button" CommandName="select" />
                    </ItemTemplate>
                </asp:TemplateField>
        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowIndex != -1)
            {
                int id = e.Row.RowIndex;
                Button btn = (Button)e.Row.FindControl("Button1");
                btn.CommandArgument = id.ToString();
            }
        }        protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName == "select")
            { 
                int rowIndex = Convert.ToInt32(e.CommandArgument);
                DropDownList ddl=GridView1.Rows[rowIndex].Cells[6].FindControl("ddl") as DropDownList;
                string ddlValue = ddl.SelectedItem.Text.Trim();
            }
        }

如上楼，在rowcomman事件中，获取DropDownList相应的值，完成正确，给楼上的加分...
