需要将文本以大写形式保存到数据库

【问题标题】：Need to save text to database in uppercase需要将文本以大写形式保存到数据库

【问题描述】：

我有一个使用 formview 和 C# 代码的 asp 4.0 页面。我有一个用于“街道名称”添加/编辑的文本框。我已经使用了 CSS text-transform:uppercase ，它将输入的文本的“外观”转换为大写，但是底层文本是在键入时使用的大小写。我需要将我的 sql 数据库中的文本保存为大写。

我在后端玩过各种形式的 FindControl，但没有运气。我可以分配一个新变量并使用文本框文本填充，然后将变量更改为大写（.ToUpper）但是我无法确定如何将变量写回文本框字段。

我希望有人知道我在说什么，因为我发现很多人想要文本框文本在大写但没有发现保存到数据库的文本全部大写。

代码如下：

    <head runat="server">

    <style type="text/css"> 
        .UpperCaseTextField
            {
                text-transform:uppercase;
            }  
    </style> 
        <link rel="shortcut icon" href="~/ImageBase/favicon.ico" type="image/x-icon"/>

【问题讨论】：

    标签： asp.net sql textbox formview uppercase


    【解决方案1】：

    您可以结合使用 CSS 和后端代码。

    在 TextBox 上使用 style='text-transform:uppercase'，在您的代码隐藏中使用 StreetTxt.Value.ToUpper();

    编辑

    在这种情况下，您可以在 ASPX 的命令中使用 UPPER 函数： http://msdn.microsoft.com/en-us/library/ms180055.aspx

    在 StreetDataSource2 中使用：

    UpdateCommand="Update [StreetTbl] Set [Streetname] = UPPER(@StreetName), [StreetState] = UPPER(@StreetState), [StreetCounty] = UPPER(@StreetCounty), [StreetCity] = UPPER(@StreetCity) Where [ID] = @ID"
InsertCommand="INSERT INTO [streetTbl] ([StreetName], [StreetState], [StreetCounty], [StreetCity]) VALUES (UPPER(@StreetName), UPPER(@StreetState), UPPER(@StreetCounty), UPPER(@StreetCity))"

    【讨论】：

    • 我尝试过使用它，但是插入/更新代码在 asp 代码中。如何更改后端/C# 并填充 StreetTxt 文本框或用于插入/更新的 @StreetName。
    • protected void StreetDetailsFvu_ItemInserting(object sender, FormViewUpdatedEventArgs e) { TextBox t; t = (TextBox)StreetDetailsFvu.FindControl("StreetTxt"); if (t != null) { t.Text = t.Text.ToUpper(); } }
    • 查看我的编辑..从未尝试过这个..但它可能有效。在命令语句中使用 UPPER 命令
    • 你知道，就像我的回答说的那样；)
    • @Matt Yep...+1。有时新手需要关于将代码放在何处的说明。
    【解决方案2】：

    我通常会回避这个，因为我希望将我的业务规则保留在数据库之外，但如果你想走这条路，你可以使用 UPPER() function 在 T-SQL 中完成。

    如果你想改用 JavaScript，你可以这样做：

    $('#<%=StreetTxt.ClientID%>').bind('keyup', function () {
    var uc = $(this).val().toUpperCase();
    $(this).val(uc);
});

    【讨论】：

    • 我知道没有其他方法可以将大小写转换为大写，并且在 sql 中广泛使用了 upper()。我的问题是将大写放在 asp 或后端代码中，以便在插入/更新之前将大小写更改为大写。我尝试了 Ed 的想法，但没有成功。已经能够使用 C# 在后端使用 upper() 更改大小写，但是不能在我的 asp 插入/更新命令中取回更改后的大小写文本。
    • 我有点不知所措。请参阅我的编辑以获取另一个选项：使用 jQuery 在 UI 中动态转换。这样，您的插入/更新命令就不必担心任何其他事情......只需获取值并保存。
