GridView内部的LinkBut​​ton可见性 [英] LinkButton Inside GridView Visibility

问题描述

我在gridview内有linkbutton
我想更改linkbutton的可见性取决于数据库返回的值
所以我创建了

i have linkbutton inside gridview
i want to change linkbutton visibility depende on value return from database
so i create that

<asp:LinkButton ID="Lnk" runat="server"  CommandArgument='<%# Bind("ArrivalMasterID") %>' Text="Cost" <big>Visible='<%# Bind("IsNewRow") %>'</big> /> 

但我有一个问题
我将linkbutton的可见性更改为isnewrow值
表示如果isbewrowvalue = ture，则为linkbutton.visible = false
我需要使用html代码而不是c#codey
任何帮助

but i have one problem
i wnat linkbutton visibility to be reverse to isnewrow value
mean if isbewrowvalue=ture then linkbutton.visible=false
i need to do it from html code not from c# codey
any help

推荐答案

关于gridview rowdatabound事件，您可以添加以下代码，保持<％#Bind(！"IsNewRow")％>这是gridview的datakey字段.

bool Isnewrow
如果(e.Row.RowType == DataControlRowType.DataRow)
{

Isnewrow = Convert.ToBool(gridview.DataKeys [e.Row.RowIndex] .Values [0]);

LinkBut​​ton lnkBut​​ton =(LinkBut​​ton)e.Row.FindControl("lnkViewDetails");
if(Isnewrow)
{
lnkbutton.visible = true;
}
其他
lnkbutton.visible = false;


将Isnewrow字段添加为gridview的数据键


< asp:GridView ID ="gridview1" AllowPaging ="true"
AutoGenerateColumns ="false" DataKeyNames ="Isnewrow"
runat ="server" ShowFooter ="true"
onrowdatabound ="grdCustomerFeedback_OnRowDataBound">

on gridview rowdatabound event you can add following code keep your <%# Bind(!"IsNewRow") %> which is as datakey field of gridview.

bool Isnewrow
if (e.Row.RowType == DataControlRowType.DataRow)
{

Isnewrow= Convert.ToBool(gridview.DataKeys[e.Row.RowIndex].Values[0]);

LinkButton lnkButton = (LinkButton)e.Row.FindControl("lnkViewDetails");
if(Isnewrow)
{
lnkbutton.visible=true;
}
else
lnkbutton.visible=false;


To add Isnewrow field as datakey of gridview


<asp:GridView ID="gridview1" AllowPaging="true"
AutoGenerateColumns="false" DataKeyNames="Isnewrow "
runat="server" ShowFooter="true"
onrowdatabound="grdCustomerFeedback_OnRowDataBound">

尝试类似的事情

Try something like this

if (e.Row.RowType == DataControlRowType.DataRow)
                  {
YourClass object = (YourClass)e.Row.DataItem;
 LinkButton lnkbtn= (LinkButton)e.Row.FindControl("Lnk");
  lnkbtn.Visible = !Convert.ToBoolean(object.Value);   
}           

好吧，这将根据您当前的实现为您完成工作.使用不(！)运算符

Well, This will do the job for you as per your current implementation. use a Not ( ! ) Operator

<br />
Visible=<%# !(Convert.ToBoolean(Eval("IsNewRow"))) %>

让我知道它是否有效.

Let me know if it work.
