Question

我在gridview中添加了一个复选框（chkCtrl）列，当选中复选框时，我想获取与该行对应的电子邮件地址，并将所有结果存储在列表或数组中。我希望在发送电子邮件时发生这种情况。单击按钮。

Gridview Code ASP.net

<asp:GridView CssClass="table table-hover" BorderWidth="2px" ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="GrabModuleID" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" >
                <Columns>
                    <asp:CommandField EditText="" ShowSelectButton="True" SelectText="View Student Details" />
                    <asp:BoundField DataField="StudentNo" HeaderText="Student Number" SortExpression="StudentNo"  />
                    <asp:BoundField DataField="Email" HeaderText="Email" SortExpression="Email" />
                    <asp:BoundField DataField="UserID" HeaderText="UserID" SortExpression="UserID" Visible="false" />
                    <asp:BoundField DataField="ModuleID" HeaderText="ModuleID" SortExpression="ModuleID" Visible="false" />
                    <asp:TemplateField>
                    <ItemTemplate>
                        <asp:CheckBox ID="chkCtrl" runat="server" />
                    </ItemTemplate>
        </asp:TemplateField>

发送电子邮件按钮代码：

<asp:Button ID="SendEmail" runat="server" class="btn btn-primary" Text="Send Class Email" OnClick="SendEmail_Click" />

Answer 1

您可以使用foreach

中的Row.Cells [index]访问BoundFields

foreach (GridViewRow row in GridView1.Rows)
{
     Control controlcbx = row.Cells[6].Controls[1]; //control for checkbox
     string email = row.Cells[2].Text; // email text
     List<string> emailList = new List<string>(); //list to save emails
     CheckBox cbx = controlcbx as Checkbox;
     if(cbx.Checked)
     {
         emailList.Add(email);
     }
}

验证Cell [index]是否与您的BoundFields匹配

逻辑非常简单。单击按钮，只需遍历gridview行并找到每行中的复选框。接下来，检查是否选中了该复选框，然后找到电子邮件地址并将其存储在集合中。

protected void SendEmail_Click(object sender, EventArgs e)
{
    List<string> emails = new List<string>(); 
    foreach (GridViewRow row in grdCustomer.Rows)
    {
        CheckBox chkCtrl = row.FindControl("chkCtrl") as CheckBox;
        if (chkCustomer.Checked)
        {
            cities.Add(row.Cells[1].Text);
        }
    }
}

选中复选框时的ASP Gridview存储数组中的值
