美好的一天

我有网格视图，其中显示员工数据。

      <asp:TabContainer ID="tcmanagers" runat="server" ActiveTabIndex="0" 
                    Width="100%">
        <asp:TabPanel ID="TabAdmins" runat="server" HeaderText="Admins" TabIndex="3">

                        ForeColor="Blue" Width="290px">Select Admins to send:</asp:Label>

                         &nbsp;&nbsp;&nbsp; 
                         <asp:Button ID="Sendadmins" runat="server" Text="Send Email" Width="201px"/>

                         <asp:TemplateField HeaderText="Check All"><HeaderTemplate>
                         <asp:CheckBox ID="chkAlladmin" runat="server" AutoPostBack="True" OnCheckedChanged="chkAllAdmin_CheckedChanged" />
                         </HeaderTemplate>

                             <AlternatingRowStyle CssClass="grdalt" />
                             <SelectedRowStyle BackColor="Fuchsia" />
                             </asp:GridView>
                                    <asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:ApplicationServices %>"
                                ProviderName="<%$ ConnectionStrings:ApplicationServices.ProviderName %>" SelectCommand="SELECT  dbo.lms_Employee.Employee_ID,dbo.lms_Employee.Employee_EMail,dbo.lms_Employee.Employee_Number, dbo.lms_Employee.Employee_Surname, dbo.lms_Employee.Employee_Name, dbo.lms_Employee.Employee_Job_Title,dbo.lms_Employee.Employee_Dept FROM dbo.aspnet_Membership INNER JOIN  dbo.aspnet_Users ON dbo.aspnet_Membership.UserId = dbo.aspnet_Users.UserId INNER JOIN  dbo.aspnet_UsersInRoles ON dbo.aspnet_Users.UserId = dbo.aspnet_UsersInRoles.UserId INNER JOIN   dbo.lms_Employee ON dbo.aspnet_Users.UserName = dbo.lms_Employee.Employee_UserName WHERE     (dbo.lms_Employee.Employee_Active = 'True') AND (dbo.aspnet_UsersInRoles.RoleId = '9ec9b26d-64a1-4736-8e82-fe6de7c7caac') and Employee_Number <> '100'">
                                </asp:SqlDataSource>
                          </ContentTemplate>
                    </asp:TabPanel>
                </asp:TabContainer>

现在我可以选择其中的所有数据，也可以选择以下代码一次选择一个数据。

Protected Sub chkAllAdmin_CheckedChanged(sender As Object, e As EventArgs)

    For Each gr As GridViewRow In GridView3.Rows
        Dim cb As CheckBox = DirectCast(gr.FindControl("chkAdmin"), CheckBox)
        If DirectCast(sender, CheckBox).Checked Then
            cb.Checked = True
        Else
            cb.Checked = False
        End If
    Next

End Sub

我想要做的是向所有选定的员工发送电子邮件。我有一个iis服务器和SQL服务器。所以我的数据库在sql server上，我的web应用程序在iis服务器上。

我不知道如何处理此任何帮助将不胜感激。

如果没有为您编码，这是我用于此类任务的策略：

将BoundField项转换为TemplateFields。执行此操作时，您可能会在ItemTemplate中为每个字段设置有意义名称的控件，例如“lblEmployeeEmail”
在按钮上单击，循环浏览GridView中的项目，对于每一行，使用FindControl（）方法查找CheckBox（然后检查是否已选中）并使用FindControl（）获取任何其他您可能需要的字段。（电子邮件标签等）

以下是通用代码模式（取自learneveryday.net）：

foreach (GridViewRow gvrow in GridView1.Rows)
{
   CheckBox CheckBox1 = (CheckBox)gvrow.FindControl("CheckBox1");
   if (CheckBox1.Checked)
   {
      // we write this code for find a label value
      Label lblLookFor = (Label)gvrow.FindControl("lblLookFor");
      string lookfor = lblLookFor.Text;
   }
}

当然，这仅包括如何获取已检查的员工以及如何从GridViewRows检索其电子邮件地址。我假设您已经知道如何发送电子邮件，但如果没有，请参阅the MSDN documentation。

使用gridview检查员工在asp.net vb中发送电子邮件给他们
