我已将div与条件..放在我的执行上,如果还显示条件,我需要将其删除..

        **My New Code**

<asp:TemplateField HeaderStyle-Width="90px" ItemStyle-Width="0">
    <ItemTemplate>  

        <div style="cursor: pointer; padding-top: 02px;" onclick="ShowfllDetails(<%#Eval("StudentID")%>);">

        if(<%# (Eval("StatusName").Equals("Processed")) %>)
        {
            //should not show the upload button                   
        }
        else
        {
         <u>Upload </u> //show the upload button
        }
        </div>

        <asp:Image ID="Image1" runat="server" ImageUrl='<%#(Eval("StatusName").Equals("Processed") ? "images/add_btn.png" : "")%>' />

    </ItemTemplate>

我在Gridview中做了这样的功能,我假设你也在做同样的事情。您可以使用linkbutton set commandArgument和Commandname属性代替标记。在触发Gridview_Rowcommand事件之后。当您点击链接按钮时,此事件将触发,您可以在数据库或会话中的某个位置设置状态,以便针对学生ID点击此链接

<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
    }
}

此绑定后,您的网格和rowdatabound查找控件并将可见性设置为true或false(已处理/未处理)

绑定你的&#34; StatusName&#34;数据库字段到标签并将标签的可见性设置为false,以便它不应显示。

现在从以下代码中了解

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;
        }
    }
}
