It's a little troublesome. Look at this.

DataGridViewCustomTextBoxColumn DataGridViewCustomTextBoxCell DataGridViewCustomTextBoxEditingControl

You will create three classes, but the first two are

public class DataGridViewCustomTextBoxColumn : DataGridViewTextBoxColumn
{
    public DataGridViewCustomTextBoxColumn() : base() {
        base.CellTemplate = new DataGridViewCustomTextBoxCell();
    }
}

public class DataGridViewCustomTextBoxCell : DataGridViewTextBoxCell
{
    public override Type EditType => typeof(DataGridViewCustomTextBoxEditingControl);
}

that's it.

last one is troublesome. Inherit your Customtextbox and implement IDataGridViewEditingControl

public class DataGridViewCustomTextBoxEditingControl : CustomTextBox, IDataGridViewEditingControl
{
      ・・・
      ・・・
      ・・・
}

Please refer to the article introduced for details.

I don't know how voluminous your CustomTextBox, it might be easier to create a third class that inherits from DataGridViewTextBoxEditingControl.
