如何在 RowDataBound 事件的 Gridview 中更改 Eval() 字段的值 [英] How to change in a Gridview on RowDataBound event the value of an Eval() field

问题描述

我有一个 GridView:

I have a GridView:

<asp:GridView ID="gvDownloads">
   <Columns>
      <asp:TemplateField HeaderText="Status" >
         <ItemTemplate>
             <%# Eval("Enabled")%>
         </ItemTemplate>
      </asp:TemplateField>
   </Columns>
<asp:GridView/>

Enabled 属性是一个布尔值.现在我想根据 Enabled 属性的 True/False 显示启用/禁用.因此我使用:

The Enabled property is a boolean. Now I would like to display Enabled/Disabled based on True/False of the Enabled property. Therefore I use:

Sub gvDownloads_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) Handles gvDownloads.RowDataBound

        If e.Row.RowType = DataControlRowType.DataRow Then

            If e.Row.Cells(3).Text = "True" Then
                e.Row.Cells(3).Text = "Enabled"
            Else
                e.Row.Cells(3).Text = "Disabled"
            End If

        End If

End Sub

但它不起作用，因为当事件启动时e.Row.Cells(3).Text 是一个空字符串.我怎么解决这个问题?谢谢

But it does not work since when the event is launched e.Row.Cells(3).Text is an empty string. How can I solve this problem? Thanks

推荐答案

If e.Row.Cells(3).Text <> Boolean.FalseString Then
       e.Row.Cells(3).Text = "Enabled"
Else
       e.Row.Cells(3).Text = "Disabled"
End If
