Disable DataGridView control automatically generate columns

In WinForm programming, when you use a DataGridView to display your data from a data source, you might see a problem: You've only specified the columns which should be display. But the gridview isn't only display that columns but also display others.

The reason: Your data source contains many data fields. Although you've created for it some need columns, the gridview will display all of them for users through a funtions called AutoGenerateColumn.

How to resolve this: It's easily. You just need disabling AutoGenerateColumn function:

Specify the columns which you want to display it for users. Of course, you must set Header text and DataPropertyName for them.

Browse your form code, go to where you set data source for the grid view. Put below code before that set data source code line (like: YOUR_GRIDVIEW_NAME.DataSource = YOUR_DATA_TABLE;):

[csharp]YOUR_GRIDVIEW_NAME.AutoGenerateColumns = false;[/csharp]
That's all.
Wish succeed!
