显示gridview的最后4位数字 [英] show last 4 digits in gridview

问题描述

我有一个asp.net GridView和具有数字例如列1234567，我想说明的最后4位数字，像这样xxx4567。这是可能的。

我是我的GridView控件绑定到如下的对象的列表：

 列表＆LT;详情＆GT; objdet = Manager.Get_Details（ID）;             如果（objdet！= NULL）
             {                 gvDetails.DataSource = objdet;
                 gvDetails.DataBind（）;
             }
 

在我的网，我有这样的：

 ＆LT; ASP：GridView控件ID =gvDetails=服务器AllowPaging =真
                AllowSorting =真的AutoGenerateColumns =false的网格线=无的CssClass =MGRID＆GT;
                ＆LT;柱体和GT;
                ＆LT; ASP：BoundField的数据字段=DetNumber的HeaderText =号码只读=真/＆GT;
＆LT; /专栏＆GT;
            ＆LT; / ASP：GridView的＆GT;
 

解决方案

在您的详细信息对象，添加另一个属性调用类似 NumberWithMask ：

 公共const int的NumberWithMaskLength = 4;公共字符串DetNumber {搞定;组; }公共字符串NumberWithMask
{
    得到
    {
        如果（string.IsNullOrEmpty（DetNumber）及！＆安培; DetNumber.Length＆GT; NumberWithMaskLength）
        {
            返回新的字符串（X，DetNumber.Length  -  NumberWithMaskLength）+ DetNumber.Substring（DetNumber.Length  -  NumberWithMaskLength）;
        }
        返回的String.Empty;
    }
}
 

然后用在相关新领域的BoundField ：

 ＆LT; ASP：BoundField的数据字段=NumberWithMask的HeaderText =号码只读=真/＆GT;
 

I have an asp.net gridview and a column that has digits e.g. 1234567, I want to show the last 4 digits like so xxx4567. Is this possible.

I am binding my gridview to a list of objects as below:

List<Details> objdet = Manager.Get_Details(ID);

             if (objdet!= null)
             {

                 gvDetails.DataSource = objdet;
                 gvDetails.DataBind();
             }

and in my grid i have this:

 <asp:GridView ID="gvDetails" runat="server" AllowPaging ="true" 
                AllowSorting ="true" AutoGenerateColumns="false" GridLines="None" CssClass="mGrid">
                <Columns>
                <asp:BoundField DataField="DetNumber" HeaderText="Number" ReadOnly="true" />
</Columns>
            </asp:GridView>

解决方案

In your Details object, add another Property called something like NumberWithMask:

public const int NumberWithMaskLength = 4;

public string DetNumber { get; set; }

public string NumberWithMask
{
    get
    {
        if (!string.IsNullOrEmpty(DetNumber) && DetNumber.Length > NumberWithMaskLength)
        {
            return new string('x', DetNumber.Length - NumberWithMaskLength ) + DetNumber.Substring(DetNumber.Length - NumberWithMaskLength );
        }
        return string.Empty;
    }
} 

Then use the new field in the relevant BoundField:

<asp:BoundField DataField="NumberWithMask" HeaderText="Number" ReadOnly="true" />
