                                    <ItemTemplate>
                                        <asp:DropDownList ID="ddlReceiptCopyStatus" runat="server">
                                            <asp:ListItem Text="firstValue" Value="1"></asp:ListItem>
                                            <asp:ListItem Text="secondValue" Value="2"></asp:ListItem>
                                        </asp:DropDownList>
                                    </ItemTemplate>
                                </asp:TemplateField>
                                <asp:TemplateField>
                                    <ItemTemplate>
                                        <asp:LinkButton ID="lbtnSubmit" runat="server" CssClass="buttonfcr" CommandName="ChangeCopyStatus"

                                            Text="Submit"></asp:LinkButton>
                                    </ItemTemplate>
                                </asp:TemplateField>
                            </Columns>
                        </asp:GridView>
                    </asp:Panel>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

我的代码在.cs文件或Onrowcommand事件中

My code inside .cs file or Onrowcommand event

protected void gridReceiptCopy_onRowcommand(object sender, GridViewCommandEventArgs e)
      {
          if (e.CommandName.Equals("ChangeCopyStatus"))
          {
              GridViewRow curruntRow = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);

              DropDownList ddlCopyStatus = (DropDownList)curruntRow.FindControl("ddlReceiptCopyStatus") as DropDownList;//copystatus dropdownlist
              string selectedNewValue = ddlCopyStatus.SelectedItem.Text;
              //here i want to get the selectedValue
          }
      }

但是我得到了我在gridBind分配的默认下拉列表..

推荐答案

protected void gridReceiptCopy_onRowcommand（object sender，GridViewCommandEventArgs e）

{

if（e.CommandName.Equals（ChangeCopyStatus））

{

GridViewRow curruntRow =（GridViewRow）（（（LinkBut​​ton）e.CommandSource） .NamingContainer）;



DropDownList ddlCopyStatus =（DropDownList）curruntRow.FindControl（ddlReceiptCopyStatus）as DropDownList; // copystatus dropdownlist

string selectedNewValue = ddlCopyStatus.SelectedValue;

//这里我想得到 selectedVa lue

}

}

protected void gridReceiptCopy_onRowcommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("ChangeCopyStatus"))
{
GridViewRow curruntRow = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);

DropDownList ddlCopyStatus = (DropDownList)curruntRow.FindControl("ddlReceiptCopyStatus") as DropDownList;//copystatus dropdownlist
string selectedNewValue = ddlCopyStatus.SelectedValue;
//here i want to get the selectedValue
}
}
