Question

我有一个gridview，其中我有一个列名“ Selection ”。我希望当管理员选择“未选择”选项时，相应的用户应该收到一封关于他被拒绝的ID的电子邮件。请参阅gridview代码以供参考：

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" AllowPaging="true" Width="920"

    <asp:TemplateField HeaderText="Selection">
        <ItemTemplate>
            <asp:Label ID="lblCountry" runat="server" Visible="true" />
            <asp:DropDownList ID="ddlCountries" runat="server">

                <asp:ListItem Text="Selected" Value="2"></asp:ListItem>
                <asp:ListItem Text="Not Selected" Value="3"></asp:ListItem>
            </asp:DropDownList>
        </ItemTemplate>

Eidted code： -

 private void SendMail()
{
    StringBuilder sbuilder = new StringBuilder();
    sbuilder.Append("<div>");
    sbuilder.Append("<p>Thanks for applying at RBL. You have been rejected</p>");
    sbuilder.Append("</div>");

    string str = sbuilder.ToString();
    string ccEmail = "";
    Common objCom = new Common();

    objCom.SendEMail(toId, "Rejection Mail", sbuilder.ToString(), ccEmail, false, "");
}


protected void ddlSelection_SelectedIndexChanged(object sender, EventArgs e)
{
    DropDownList ddl = (DropDownList)sender;
    GridViewRow row = (GridViewRow)ddl.Parent.Parent;


    if (ddl.SelectedValue == "Not Selected")

        SendMail();
    }
}

试试这个，

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
   {

   if(e.Row.RowType == DataControlRowType.DataRow)
   {
      DropDownList ddl = e.Row.FindControl("ddlCountries") as DropDownList;
     if(ddl != null)
     {
        ddl.SelectedIndexChanged += new EventHandler(ddlCountries_SelectedIndexChanged);
     }
   }

 }

protected void ddlCountries_SelectedIndexChanged(object sender, EventArgs e)
{
     string selectedValue = ((DropDownList)sender).SelectedValue;
     if(selectedValue== "Not Selected")
     {
        // Write code here for sending mail
     }

 }

Dropdown中的Onselect向相应用户发送邮件
