<asp:BoundField DataField="FIsView" HeaderText="完成情况" SortExpression="FIsView"></asp:BoundField>
</asp:GridView>

我想在CS代码里面把"完成情况"这一列隐藏因该怎么做？

[解决办法]

<asp:BoundField DataField="FIsView" HeaderText="完成情况" SortExpression="FIsView" Visible=false> </asp:BoundField >

[解决办法]
把你的判断条件写出来..

可以尝试:
Visible=<%=num>1?"false":"true"%>

[解决办法]
ls的正解
[解决办法]
gridView.Columns[0].Visible = false;

隐藏第0列
[解决办法]
gridView.Columns[0].Visible = false;
