- /////////////////////////////////////////////////////////////////////////////
- Use:
-
- This sample demonstrates how to host a control in the current DataGridViewCell
- for editing.
-
-
- /////////////////////////////////////////////////////////////////////////////
- Remark:
-
- There're six standard DataGridViewColumn types for use as follows:
-
- DataGridViewTextBoxColumn
- DataGridViewCheckedBoxColumn
- DataGridViewComboBoxColumn
- DataGridViewLinkColumn
- DataGridViewButtonColumn
- DataGridViewImageColumn
-
- However, developers may want to use a different control for editing on the column,
- e.g. MarkedTextBox, DateTimePicker etc. This feature can be achieved in two ways:
-
- 1. Create a custom DataGridViewColumn;
-
- For the details of how to do this, please refer to the CustomDataGridViewColumn
- sample.
-
- 2. Place the editing control on the current cell when editing begins, and hide
- the editing control when the editing completes.
-
- This sample demonstrates how to do this.
-
-
- /////////////////////////////////////////////////////////////////////////////
- Code Logic:
-
- 1. Create an instance of the editing control, in this sample the editing control
- is MaskedTextBox.
-
- 2. Specify a mask for the MaskedTextBox and add the MaskedTextBox to the
- control collection of the DataGridView;
-
- 3. Hide the MaskedTextBox;
-
- 4. Handle the CellBeginEdit event to show the MaskedTextBox on the current
- editing cell;
-
- 5. Handle the CellEndEdit event to hide the MaskedTextBox when editing completes;
-
- 6. Handle the Scroll event to adjust the location of the MaskedTextBox as it is
- showing when scrolling the DataGridView;
-
- 7. Handle the EditingControlShowing event to pass the focus to the MaskedTextBox
- when begin editing with keystrokes;
