当我单击某一行的按钮字段时,我会被引导到一个新页面,该页面要求我执行一些任务。
每当执行任务时,我想为该特定用户禁用“执行任务”按钮字段
我如何才能做到这一点?请尝试以下代码:
<asp:GridView ID="GridView1" runat="server" OnRowDataBound="GridView1_RowDataBound" ...>
Other settings
</asp:GridView>
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
var button = (Button) e.Row.Cells[e.Row.Cells.Count - 1].Controls[0];
button.Enabled = CanCurrentUserViewButton();
}
}
private bool CanCurrentUserViewButton()
{
//Logic...
}
其他设置
受保护的void GridView1_RowDataBound(对象发送方,GridViewRowEventArgs e)
{
如果(e.Row.RowType==DataControlRowType.DataRow)
{
var button=(button)e.Row.Cells[e.Row.Cells.Count-1]。控件[0];
button.Enabled=CanCurrentUserViewButton();
}
}
私有布尔值CanCurrentUserViewButton()
{
//逻辑。。。
}
在数据库TaskStatus中创建一列,用于维护任务的状态。在该列上,您可以启用或禁用按钮,但我如何管理单个用户登录?如果PosterName
引用当前用户,您需要禁用执行任务
按钮,对吗?或者,根据当前用户身份,是否启用/禁用PerformTask
列?@nativehr-我想禁用特定用户的PerformTask按钮字段。不是所有按钮,而是他单击的按钮。您可以编写一些代码来决定用户是否应查看按钮。请查看此帖子:
