I'm using a datagridview to add new users to the table that accesses users names and passwords for access to the application. In the database, the field has a mask of '******' However, when the password is displayed in the datagridview, the actual password is displayed. Is there anyway of masking the password column? I don't see any property to change this when you "Edit Columns" for the datagridview.

Hi Julie Missick,

We can change the exact display value by handling CellFormatting event. Please try the following code:

EventArgs e)

DataTable dt1 = new DataTable("customer");

"name");

"password");

"aa","aaa");

DataGridViewCellFormattingEventHandler(dataGridView1_CellFormatting);

DataGridViewCellFormattingEventArgs e)

String('*', e.Value.ToString().Length);

The following link is for your reference.

DataGridView.CellFormatting Event

If you have any other questions, please feel free to ask.

Best regards,

Ling
