我想隱藏打印頁面中的列。隱藏打印頁面中的特定列c#
這裏是顯示ID
行的影像仍清晰可見:
我想隱藏的ID
列。
這裏是我正在使用的代碼,我已經聲明this.dataGridView.Columns["ID"].Visible = false
,但ID
列仍然可見。

任何幫助我該如何解決這個問題?
謝謝!
您的回答將非常感謝!
謝謝你的回答。但是我又遇到了一個問題,列ID不見了,但ID號仍然存在,就像這張圖片:(我上傳到保管箱中):https://www.dropbox.com/s/gxagdwujkma3kb0/Capture.PNG 謝謝 – Kaoru
@Kaoru對於'foreach(GridRow.Cells中的DataGridViewCell Cel)',您應該過濾屬於ID列的單元格。 (例如,您可以檢查「Cel.ColumnIndex」)。考慮重新設計你的邏輯。 – etaiso
非常感謝您的先生。我會考慮重新設計我的這個打印頁面的邏輯:) – Kaoru
