C＃中的DataGridViewTextBoxEditingControl和TextBox有什么区别

Question

For an example,

void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
     TextBox txtbox = e.Control as TextBox;
     if (txtbox != null)
     {
          //
     }

and

void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
     Control ctl = e.Control;
     DataGridViewTextBoxEditingControl dText = (DataGridViewTextBoxEditingControl)ctl;
     if (dText!= null)
     {
          //
     }

What is the advantage DataGridViewTextBoxEditingControl instead TextBox?

Help me..

Answer 1

DataGridViewTextBoxEditingControl is derived from TextBox and it has some properties related to the DataGridView behavior.

Straight from the MSDN documentation :

The DataGridViewTextBoxEditingControl class is a specialized type of TextBox control that implements the IDataGridViewEditingControl interface, allowing it to be hosted in a DataGridViewTextBoxCell when the cell is in edit mode.

Handle the EditingControlShowing event to perform custom initialization of the editing control when a cell enters edit mode. To customize the display characteristics of the control, set the properties of the object returned by the DataGridViewEditingControlShowingEventArgs.CellStyle property rather than setting the properties of the control returned by the DataGridViewEditingControlShowingEventArgs.Control property.
