    Hello,

    I contact you because I have 2 questions about the events of RagGridView control.

    1. I have 2 columns in my GridView (one GridViewTextBoxColumn readonly and one GridViewDecimalColumn editable). The decimal column can have a null value or a decimal value.
      I handle these events : CellValidating, RowValidating and RowValidated. In the CellValidating, I check if my decimal column has a value and in this case it must be between min and max value and display the Row.ErrorText and cancelling the validating event. However if the decimal value is null, I have to ask the user a confirmation when the row is validating, so I do that in the RowValidating event. If the user does not confirm, I cancel the RowValidating and I would like to set the decimal cell as the current cell and BeginEdit. Is it possible in the RowValidating event set a current cell and BeginEdit (in a new row or an existing row) ?
    2. In the GridView I register a custom GridNewRowBehavior and override the ProcessEscapeKey method that execute this code :
      bool canceled = this.GridViewElement.CancelEdit();
      this.GridControl.MasterView.TableAddNewRow.CancelAddNewRow();

      return canceled;       
      If the gridView is in edit mode on the new row or an existing row and I press the Escape key, my custom behaviour performs perfectly this treatment. But the RowValidating and RowValidated events in my form fires. How can I detect in these events that the edit mode is canceling because I would like to reset some properties ?

    Thank you
    Fabrizio
