C# 当复选框未选中时，如何使GridView中的此行为灰色？

我有以下数据库设计：

Employee Table: Username, Name, JobTitle, BadgeNo, IsActive, DivisionCode
Divisions Table: SapCode, DivisionShortcut

我有一个GridView，我正在使用它添加、删除和更新/编辑员工信息。此信息是员工用户名、姓名、徽章号、职务、IsActive和部门快捷方式IsActive是一个标志，指示员工是否可用或是否在工作分配中。我将其设置为复选框，该列应显示两个值；活跃和不活跃。在编辑模式下，将显示复选框。如果选中，则表示该员工可用，否则该员工处于非活动状态

我编写了代码，一切正常，但现在我只面临一个问题，那就是：当复选框未选中时，这意味着员工处于非活动状态，因此我希望显示其信息的行为灰色（如禁用）

那么怎么做呢？

ASP.NET代码：

<%-- GridView for User Management Subsystem --%>
        <asp:GridView ID="GridView1" runat="server" AllowSorting="True" 
            AutoGenerateColumns="False" DataKeyNames="Username"

在复选框未选中状态的方法中，您将设置GrdiViewRow的背景色，如下所示

gvrow.BackColor=Color.Gray

一个重要的想法是，在第一次加载时，您需要重复GridView的OnRowDataBound的类似逻辑，以便将其移入方法并重用

protected void isActive_OnCheckedChanged(object sender, EventArgs e)
    {
        CheckBox chkStatus = (CheckBox)sender;
        GridViewRow gvrow = (GridViewRow)chkStatus.NamingContainer;

        //Get the ID which is the NetworkID of the employee
        string username = gvrow.Cells[2].Text;
        bool status = chkStatus.Checked;
if(!status)//this is checkbox is unchecked then set backcolor to Gray
{
gvrow .BackColor = Color.Gray;
}

.......

我不明白你的意思。你能再解释一下吗？它不起作用。为什么？是因为我已经在ASP.NET代码中定义了GridView的背景色，如上面的代码所示。它不起作用。为什么？是否因为我已经在ASP.NET代码中定义了GridView的背景色，如上面的代码所示。可能是，但我不这么认为？通过从gv上拆下进行检查。
protected void isActive_OnCheckedChanged(object sender, EventArgs e)
    {
        CheckBox chkStatus = (CheckBox)sender;
        GridViewRow gvrow = (GridViewRow)chkStatus.NamingContainer;

        //Get the ID which is the NetworkID of the employee
        string username = gvrow.Cells[2].Text;
        bool status = chkStatus.Checked;
if(!status)//this is checkbox is unchecked then set backcolor to Gray
{
gvrow .BackColor = Color.Gray;
}

.......

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
 if (e.Row.RowType == DataControlRowType.DataRow)
 {
    // First check Checkedbox is check or not, In Cells insert you IsActive column index
    if( e.Row.Cells[1].Text == "False" )
        GridView1.BackColor = Color.Gray;

 }
}
