好的...所以我正在尝试使用 GridView 显示我的数据库中的表中的数据。我需要更改列的显示顺序，并且需要根据用户浏览网站的语言（法语或英语）显示/隐藏某些列。

到目前为止，在我的代码中我有这个。数据通过数据源加载。

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    LoadS25ATransactionsData()

End Sub


Private Sub LoadS25ATransactionsData()

    gvS25ATransactions.Visible = True
    gvS25ATransactions.DataSource = ViewS25A.GetS25ATransactions
    gvS25ATransactions.DataBind()

End Sub

我尝试了很多方法来更改列的顺序并隐藏和显示其他但无济于事。请帮忙！

谢谢！

您可以使用 GridView.Columns[0] 按索引隐藏列或按名称隐藏列，如下例所示。

<asp:GridView runat="server" ID="GridView1" 
   AutoGenerateColumns="False" OnPreRender="GridView_PreRender">
    <Columns>
        <asp:BoundField DataField="LastName" HeaderText="LastName" />
        <asp:BoundField DataField="FirstName" HeaderText="FirstName" />
    </Columns>
</asp:GridView>

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        var users = new List<User>
            {
                new User {FirstName = "John", LastName = "Doe"},
                new User {FirstName = "Marry", LastName = "Newton"},
                new User {FirstName = "Joe", LastName = "Black"}
            };

        GridView1.DataSource = users;
        GridView1.DataBind();
    }
}

protected void GridView_PreRender(object sender, EventArgs e)
{
    foreach (DataControlField column in GridView1.Columns)
        if (column.HeaderText == "FirstName")
            column.Visible = false;
}
