<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Mobile") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server"
Text='<%#GetPhone(Eval("Mobile").ToString(),Eval("Phone").ToString())%>'></asp:Label>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
后台方法： /// <summary>
/// 返回有效联系电话
/// </summary>
/// <param name="mobile">手机字符串</param>
/// <param name="phone">电话字符串</param>
/// <returns></returns>
public static string GetPhone(string mobile, string phone)
{
if (mobile.Trim().Length > 0 && phone.Trim().Length > 0)
{
return mobile.Trim().ToString();
}
else if (mobile.Trim().Length > 0 && phone.Trim().Length <= 0)
{
return mobile.Trim().ToString();
}
else
{
return phone.Trim().ToString();
}
}
