如何使< ASP：DataGrid列在其数据绑定时不可见？ [英] How do a make an <ASP:DataGrid column invisible when its data bound?

问题描述

附加代码，但是给我一个错误的行是

MyDataGrid.Columns（2）.Visible = False

它实际上给了我一个错误，而不是2，即使存在9个绑定的b / b $ b列数据。我如何隐藏列？谢谢。


MyConnection =新

SqlConnection（" server =（local）; database = pubs; Truste d_Connection = yes"）

MyCommand = New SqlDataAdapter（" select * from Authors"，

MyConnection）


DS =新数据集

MyCommand.Fill（DS，作者）

MyDataGrid.DataSource = DS.Tables（" Authors"）。DefaultView

MyDataGrid.DataBind（）

MyDataGrid.BackColor = Color.White

MyDataGrid.BorderColor = Color.Violet

MyDataGrid.BorderStyle = BorderStyle.Dotted

MyDataGrid.ToolTip =" JBs table"


''!!!!!!错误行 - 超出范围，但有9列。

MyDataGrid .Columns（2）.Visible = False

< ASP：DataGrid id =" MyDataGrid" RUNAT = QUOT;服务器" Width =" 700"

BackColor =" #ccccff" BorderColor =" black"

ShowFooter =" false" CELLPADDING = QUOT; 3英寸CELLSPACING = QUOT; 3英寸Font-Name =" Verdana"

字体大小=" 8pt" HeaderStyle-BackColor =" #aaaadd"

EnableViewState =" false" />

解决方案

既然你知道要隐藏Col.2为什么不把它设置为

在设计时间可见=假？

感谢您提供反馈....但由于其数据绑定，该列不存在于

设计时间只限运行时间！因此我正在寻找一种隐藏数据的运行时方式（我希望将数据与行关联但不向用户显示）

... in你只想说从SQL语句中删除它！

谢谢。

Ofcource，没有人会建议从SQL中删除col ..

但是这里有你可以试试的东西..

在你试图隐藏之前检查数据网格中是否有一些数据

col。

当你试图隐藏时，Lemme知道数据网格是否有任何数据

col。

Hi,

Code attached but the line that gives me an error is
MyDataGrid.Columns(2).Visible = False
It actually gives me an error for any value instead of 2 even when 9 bound
columns of data exist. How do i hide a column? Thanks.

MyConnection = New
SqlConnection("server=(local);database=pubs;Truste d_Connection=yes")
MyCommand = New SqlDataAdapter("select * from Authors",
MyConnection)

DS = New DataSet
MyCommand.Fill(DS, "Authors")
MyDataGrid.DataSource = DS.Tables("Authors").DefaultView
MyDataGrid.DataBind()
MyDataGrid.BackColor = Color.White
MyDataGrid.BorderColor = Color.Violet
MyDataGrid.BorderStyle = BorderStyle.Dotted
MyDataGrid.ToolTip = "JBs table"

''!!!!!!Error line - out of range althought there are 9 columns.
MyDataGrid.Columns(2).Visible = False
<ASP:DataGrid id="MyDataGrid" runat="server" Width="700"
BackColor="#ccccff" BorderColor="black"
ShowFooter="false" CellPadding="3" CellSpacing="3" Font-Name="Verdana"
Font-Size="8pt" HeaderStyle-BackColor="#aaaadd"
EnableViewState="false" />

解决方案

Since you know that you want to hide Col.2 why dont you set it to
visible=false during the design time?

Thanks for feedback....but as its databound the column does not exist at
design time only run-time! Therefore im looking for a run-time way of hiding
the data (i want to associate data with the row but not show it to the user)
...in case you were going to just say remove it from the SQL statement!
Thanks.

Ofcource, No one will ever suggest to remove the col from SQL..
But here is something you can try..
Check if there is actually some data in the datagrid before you try to hide
the col.
Lemme know if there is any data is the datagrid when u are trying to hide
the col.
