推荐答案

我已经做了内部的GridView这样的功能，我假设你正在做的一样。代替标签可以使用的LinkBut​​ton设置commandArgument和的CommandName属性。之后，消防Gridview_Rowcommand事件。当过，你会点击LinkBut​​ton的这一事件将触发，您可以在会话设置状态数据库或其他地方，这个链接被点击针对学生证

I have done such a functionality inside Gridview, I assume you are doing the same. In place of tag you can use linkbutton set commandArgument and Commandname properties. AFter that fire Gridview_Rowcommand event. when ever you will click on linkbutton this event will fire and you can set the status in database or somewhere in session that this link is clicked against student id

<asp:LinkButton ID="LinkButton1" runat="server" Text="Upload" CommandName="Upload"
                        CommandArgument='<%#Eval("StudentID")%>'></asp:LinkButton>

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "Upload")
    {
        // get student id against clicked link button
        int studentid = Convert.ToInt16(e.CommandArgument);
        // -- set status in database it is clicked
    }
}

在此之后绑定网格和的RowDataBound找到控制和可见性设置为true或false（加工/不处理）

after this bind your grid and on rowdatabound find control and set the visibility to true or false (Processed/Not Processed)

您绑定StatusName的数据库字段添加到标签和可见性设置为false标签，所以它不应该显示。

Bind your "StatusName" database field to a label and set the visibility to false of Label so that it should not display.

现在采取的想法从下面code

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // Display the company name in italics.
        Label lblAssignto = (Label)e.Row.FindControl("lblassignto");
        LinkButton addevent = (LinkButton)e.Row.FindControl("lnkBtnAddEvent");
        LinkButton showevent = (LinkButton)e.Row.FindControl("lnkBtnShowEvent");
        if (string.IsNullOrEmpty(lblAssignto.Text))
        {
            addevent.Visible = false;
            showevent.Visible = false;
        }
        else
        {
            addevent.Visible = true;
            showevent.Visible = true;
        }
    }
}
