怎么获取gridview中下拉列表的值

protected void Button1_Click(object sender, EventArgs e)
{
DropDownList dd = (DropDownList)GridView1.FindControl("DropDownList2");
int c = dd.Items.Count;

    for (int i=0; i < c; i++) {
        DropDownList ddl = (DropDownList)GridView1.Rows[i].FindControl("DropDownList2");
        string str = ddl.SelectedItem.Value;
        Response.Write(str);  
    }
        //String fen=dd.SelectedValue.ToString();
        //Response.Write(fen);
        Response.Write("<script>alert('提?交?成é功|！?')</script>");
}

DropDownList dd = (DropDownList)GridView1.FindControl("DropDownList2");
string s = dd.SelectedValue;
就可以了。

你有多个dropdown，你需要给它们不同的name和id

DropDownList ddl = (DropDownList)GridView1.Rows[i].FindControl("DropDownList2");
->
DropDownList ddl = (DropDownList)GridView1.Rows[i].FindControl("DropDownList" + i.ToString());
