gridview 中如何判断条件呢？

Question

gridview有多列，后台数据绑定，其中有一列的内容只有判断后才能显示，如：某个字段的内容是1就显示，为0就不显示，，，，这是在前台判断还是在后台判断呢，怎么判断呢？<asp:TemplateField ItemStyle-Width="8%" ItemStyle-CssClass="class1">
                                <ItemTemplate>
                                    <asp:HyperLink ID="HyperLink1" runat="server">显示这个内容</asp:HyperLink>
                                </ItemTemplate>

Answer 2

应该是先在gridview里获取要判断的值……然后进行判断，如果为零，找到哪儿列的visibie为false，这样就可以了……你试试看

Answer 3

sql里也可以判断啊，查到字段为1的数据不就行了？？？

Answer 4

写个public方法放在。cs中，然后在。aspx中数据绑定时调用

//相关Row数据处理
        protected void GVDesignList_RowDataBound(object sender, GridViewRowEventArgs e)

                               if (btnDel != null)
                {
                    btnDel.Attributes.Add("onclick", "return confirm('你确定要删除所选择的数据行吗?');");
                }                                             
               //删除按钮
                
                if (((Label)e.Row.Cells[60].FindControl("lblAdidName")).Text.Trim() == UserName)

Answer 6

既然是绑定的时候 有条件不能为1或者 不能为0   为嘛不在sql里面写好了绑定呢？就and  state!=0 什么的东东

Answer 7

sql
執行數據庫時判斷  decode(result,1,'顯示','不顯示')

Answer 8

或者在databound裏面進行判斷還有一種方法，是在後臺cs中寫好判斷的函數，IsShow(string sts)在前臺綁定的時候調用這個方法  <asp:Label ID="sts" runat="server" Text='<%#IsShow(Eval("sts").ToString())%>'   ></asp:Label>

Answer 9

后来判断固然可以，但是还是比较麻烦，还是在sql里面增加一个判断条件比较好

Answer 10

<%# Eval("sex").ToString()=="1"?"显示这个数据":""%>

Answer 11

Rowdatabound事件里面写！楼上有人已经给出代码了
