c# - DataGridView has too much columns

Question

I have a winforms that contains a dataGridView. The datagridView contains 4 columns (1 checkbox, and 3 text).

When I load my form, I am loading data in a list of object (almost 15 attributes).

In my columns, I just have 3 values of my Objects that must be displayed, and the others will be use, programmatically, but not visible for the user.

The problem is, when I add the list as the DataSource of my GridView, I got the 3 columns, with values I want, but also 1 columns for each of the others attributes...

Why does the other columns appears, when I do not add them in my code?

I do not found the DataGridView property that will prevent this columns to be add.

Answer 1

将AutoGenerateColumnsDataGridView 的属性设置为false

您可以通过代码设置

datagridview.AutoGenerateColumns = false;
datagridview.DataSource = mydatasource;

更新 ：

此属性在 ASP.net Gridview 中可浏览，但在设计器中的 WinForms 中不可浏览

那是因为这个属性设置为 browsable false

Answer 3
