asp.net - 数据绑定时gridview中按钮的可见错误？在 Asp.net 中？

Question

在 Web 应用程序中，我将在绑定数据时禁用按钮，是否有可能像这样显示错误？

 <asp:Button ID ="btn" runat ="server"  CommandArgument='<%# Eval("id").ToString() == "1"? visble false: Visible true %>' />

Answer 1

Either do that in the data bound event or do it like this...

<asp:Button ID ="btn" runat ="server" Visible='<%# Eval("id").ToString() == "1"? "false" : "true" %>' />

Answer 2

在 DataGrid RowDataBound 事件中执行此操作

Answer 3

尝试这个：

 <asp:Button ID="Button1" runat="server" Text="Button" Visible='<%#getVisibility()%>' OnClick="btn_Click" />

代码背后：

public Boolean getVisibility()
{
   Boolean b = false;
   //get the boolean value based on your field condition
   b = Convert.ToBoolean(Eval("FieldValue").ToString() != "MatchCondition" ? "true" :     "false");
   return b;
}
