请问怎样取得gridview中的dropdownlist的值

Question

string str = ((DropDownList)(e.Item.Cells[i].FindControl("关键字"))).SelectedItem.Text;

Answer 1

我的更新是在sqldatasource中做的，我的取值方式是这样的：
protected void GridSqlDataSource_Updating(object sender, SqlDataSourceCommandEventArgs e)
    {
        
        this.GridSqlDataSource.UpdateParameters["publishid"].DefaultValue = ((DropDownList)this.GridView1.Rows[this.GridView1.EditIndex].FindControl("editIssueDropDownList")).SelectedValue;        
        this.GridSqlDataSource.UpdateParameters["filename"].DefaultValue = ((FileUpload)this.GridView1.Rows[this.GridView1.EditIndex].FindControl("FileUpload2")).FileName;
        this.GridSqlDataSource.Update();
    }
但更新到数据库后是空值。这是为什么？

Answer 2

this.GridView1.EditIndex这个有值？

Answer 3

 foreach (GridViewRow gvr in GD_data.Rows)
{
                string a = dt.Rows[0]["status"].ToString();
                DropDownList L1 = (DropDownList)gvr.FindControl("DDL_status");
}

Answer 4

Answer 6

最完整的
//更新
    protected void GV_Product_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        DropDownList ddl = (DropDownList)GV_Product.Rows[GV_Product.EditIndex].FindControl("DropDownList1");        
        Label lab = (Label)GV_Product.Rows[e.RowIndex].Cells[0].FindControl("lab_keepid");        //获得控件里的值
        int identitys = Convert.ToInt32(ddl.SelectedItem.Value);
        int id = Convert.ToInt32(lab.Text);
}
//编辑
    protected void GV_Product_RowEditing(object sender, GridViewEditEventArgs e)
    {
        Label lab = (Label)GV_Product.Rows[e.NewEditIndex].Cells[0].FindControl("lab_keepid");
    }

注意看你界面源代码底下的GridView中的编辑模板下是否有DropDownList,
   <asp:TemplateField HeaderText="用户Id" SortExpression="employeeId">
                    <EditItemTemplate>
                       编辑模板下应该放个你想得到模板
                    </EditItemTemplate>
                    <ItemTemplate>
                        <asp:DropDownList ID="DropDownList1" runat="server"></asp:DropDownList>
                    </ItemTemplate>
                </asp:TemplateField>有的话才能找到
