在asp.net的gridview中按ID隐藏列

Question

I have the asp.net application where I am having the editable grid view with the edit,Delete,Add options. this grid having as usual Template fields . I want to hide some columns. I know i can do that by using columns index. but i don't want to follow it. instead I want to hide columns by Id. this is because if in my application further I need to add more columns then there is need to change the code gain and again in the core. so I am choosing this way. Bu as i found <asp:TemplateField /> does not contain Id attribute. so it is become impossible for me to hide <asp:TemplateField/> by Id. any remedy for this ?

Answer 1

You can always do it using column header text. Run a loop through columns of the grid view and compare header text of the column with the constant declared and hide the column, this way, if you are adding any number of columns before or after the column will not affect the code.

Answer 2

也许在模板字段内创建一个具有ID的div，然后使用客户端代码隐藏该div。

Answer 3

Perhaps just have a different grid markup for each "view" you want to show to the user, so one grid with all the columns, and another with limited columns.

I am assuming you would always be binding the same data to the grid (regardless of whether you are hiding/showing columns), so then you would just need some logic in your code to determine what "view" you want to show the user (ie what grid you want to bind to).
