如何在 LinkButton 单击事件的 GridView 中获取单元格值？还是行命令？

Question

我有一个 GridView，其中包含多条记录和几个 Link 名为编辑和详细信息的按钮。现在我想在用户单击详细信息 Link 按钮时获取用户名（不是索引）。像 "Name"、"FatherName" 等这是 .aspx 代码

<asp:GridView ID="dgvEmployeesInformation" runat="server" CssClass=" table table-bordered table-hover table-responsive" DataKeyNames="Id" AutoGenerateColumns="False" OnRowCommand="dgvEmployeesInformation_RowCommand" OnRowDataBound="dgvEmployeesInformation_RowDataBound" AllowPaging="True" AllowSorting="True" OnPageIndexChanging="dgvEmployeesInformation_PageIndexChanging">
    <%--1st Column--%>
    <Columns>
        <asp:BoundField HeaderText="ID" DataField="Id" ControlStyle-BackColor="#0066ff" Visible="False">
            <ControlStyle BackColor="#0066FF"></ControlStyle>
        </asp:BoundField>
        <asp:BoundField HeaderText="Name" DataField="Name" />
        <asp:BoundField HeaderText="Employee No" DataField="EmployeeNo" />
        <asp:BoundField HeaderText="Father Name" DataField="FatherName" />
        <asp:HyperLinkField DataNavigateUrlFields="Id" DataNavigateUrlFormatString="AddEmployeeBasic1.aspx?thid={0}" HeaderText="Update" NavigateUrl="~/AddEmployeeBasic1.aspx" Text="Edit" />
        <asp:TemplateField HeaderText="Action" ShowHeader="True">
            <ItemTemplate>
                <asp:LinkButton ID="lbDelete" runat="server" CausesValidation="False" CommandName="Delete" Text="Delete"></asp:LinkButton>
            </ItemTemplate>
        </asp:TemplateField>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:LinkButton runat="server" ID="lbDetail" OnClick="lbDetail_Click" DataNavigateUrlFields="Id" DataNavigateUrlFormatString="EmployeesDetails.aspx?EmpID={0}" NavigateUrl="~/EmployeesDetails.aspx" HeaderText="Show Detail" Text="Detail"></asp:LinkButton>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

这是lbDetail_Click代码

protected void lbDetail_Click(object sender, EventArgs e)
{
    GridViewRow clickedRow = ((LinkButton)sender).NamingContainer as GridViewRow;
    Label lblUserName = (Label)clickedRow.FindControl("Name");
    EmployeeID.EmpName = lblUserName.ToString();
}

当我将程序置于调试模式时，lblUserName return NULL 这是图片。

我想要的是，当用户单击 Detail LinkButton，然后在 lbDetail Click 事件上，它获取员工的姓名并将其存储在静态变量中。下面是图片

我不明白如何解决这个问题。请帮我解决这个问题。非常感谢您的帮助。

Answer 1

lblUserName 为空，因为它不是 Label，而是 BoundField。你可以做什么来获取 Cell 值。

protected void lbDetail_Click(object sender, EventArgs e)
{
    GridViewRow clickedRow = ((LinkButton)sender).NamingContainer as GridViewRow;
    Label1.Text = clickedRow.Cells[1].Text;
}

或者使用包含标签的 TemplateField Name

<asp:TemplateField HeaderText="Name">
    <ItemTemplate>
        <asp:Label ID="Name" runat="server" Text='<%# Eval("Name")%>'></asp:Label>
    </ItemTemplate>
</asp:TemplateField>

Answer 2

我只是将数据属性添加到详细信息按钮，然后在后面的代码中获取它的值。

例如：

1.) 添加新的 data-myData='<%# Eval("Name") %>' 属性及其值到按钮

                    <asp:TemplateField>
                        <ItemTemplate>
                            <asp:LinkButton runat="server" ID="lbDetail" OnClick="lbDetail_Click" Text="Detail" data-ID='<%# Eval("ID") %>' data-myData='<%# Eval("Name") %>' ></asp:LinkButton>
                        </ItemTemplate>
                    </asp:TemplateField>

2.) 从事件处理程序中获取这些数据

protected void lbDetail_Click(object sender, EventArgs e)
{
     LinkButton button = (LinkButton)sender;
     var name = (string)button.Attributes["data-myData"];
     var selectedID = (string)button.Attributes["data-ID"];
     Session["selectedID"] = selectedID ;
}

Answer 3

您的代码应如下所示：

protected void lbDetail_Click(object sender, EventArgs e)
{
    GridViewRow clickedRow = ((LinkButton)sender).NamingContainer as GridViewRow;
    var username = clickedRow.Cells[1].Text;
    if(string.IsNullOrEmpty(username))
    {
        return;
    }
    EmployeeID.EmpName = username;
}
