WinForm DataGridView does not show default first column does not show unbound column data source changes automatically when changed (GO)

The first column with an asterisk is not displayed:

Set Rowheadersvisiber to False in the DataGridView property box

Do not show unbound columns:

DataGridView has a property of AutoGenerateColumns. But what's not understandable is that this property is not in the property box, so you can't find it there. Can only be set in the background code.

This.datagridview1.AutoGenerateColumns = false;

Automatically update when the data source changes:

The DataGridView data source is often changed during page operations. We certainly want the display of DataGridView to be consistent with its data source, but when the data source changes, we have to re-assign it in common sense.

This.datagridview1.datasource = changed data source object; But it's not going to change the display, and even if we add a word to it later,

This.datagridview1.refresh (); it's still not going to change. To achieve the purpose, the following methods can be used:

This.datagridview1.datasource = null;

This.datagridview1.datasource = changed data source object;
