if your application is in asp.net then try this protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { // Replace the password cell value with asterisks e.Row.Cells[1].Text = new string('*', e.Row.Cells[1].Text.Length); } }

Hello NURU, As @Amit suggested you can do as below. private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e) { if (e.ColumnIndex == passwordColumnIndex && e.Value != null) { e.Value = new string('*', e.Value.ToString().Length); e.FormattingApplied = true; } } Also, You would need to attach this event handler to your DataGridView control in your form's constructor or Load event, like this: dataGridView1.CellFormatting += dataGridView1_CellFormatting; Thanks Naimish Makwana
