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，我用它来添加、删除和更新/编辑员工信息。此信息是员工用户名、姓名、徽章编号、职位名称、IsActive 和部门快捷方式。IsActive 是一个标志，指示员工是否有空或在分配中。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，否则表示不活动。

我编写了代码，一切正常，但现在我只面临一个问题，如下所示：当未选中复选框时，这意味着员工处于非活动状态，所以我希望显示他的信息的行为灰色（像残疾人）。

那么该怎么做呢？

ASP.NET 代码：

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

        bool status = chkStatus.Checked;

        string connString = ConfigurationManager.ConnectionStrings["UsersInfoDBConnectionString"].ConnectionString;
        SqlConnection conn = new SqlConnection(connString);

        string updateIsActive = "UPDATE Employee SET IsActive = @IsActive WHERE Username = @Username";

在您的复选框未选中状态的方法中，您将像这样设置 GrdiViewRow 的 BackColorgvrow.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，因此将其移动到方法中并重用

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;
}

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;

 }
}
