Negative values with EditorWithMask

180

Mark posted over 15 years ago

I am implementing an EditorWithMask editor in a specific UltraGridCell so that I can add an EditorButton on the right as well as a SpinButton. The problem I have with the code below is that it will not allow negative values to be entered. Please can someone help?

Dim num As New Infragistics.Win.EditorWithMask
num.ExpectedType = GetType(Single)
num.SpinButtonDisplayStyle = Infragistics.Win.SpinButtonDisplayStyle.OnRight
Dim btn As New Infragistics.Win.UltraWinEditors.EditorButton()
btn.Text = "::"
AddHandler btn.Click, AddressOf <SubProcedure>
num.ButtonsRight.Add(btn)
row.Cells(0).Editor = num

I have tried setting the Cell Style as below, but this makes no difference

row.Cells(0).Style = Infragistics.Win.UltraWinGrid.ColumnStyle.DoubleWithSpin

You need to set the MaskInput property of the grid column to allow negative numbers. You do this by putting a minus sign in the mask. For example: "-nnnn.nn"

The problem with this is that each cell/row in the column could have a different data type and therefore a different input mask. Is there a way of setting the MaskInput at the Cell level?

Yes, what you would have to do is use an Editor, like UltraMaskedEdit or UltraNumericEditor. Set the mask property on the editor control and assign it to the individual cells you want. Set the column's UseEditorMaskSettings property to true to tell the cells in the column to use the editor settings rather than it's own mask properties.

Thanks for your help - I have made some progress using UltraNumericEditor, but this has now raised another problem. If you review the sample code below, the btn.Click event now does not fire when added to the UltraNumericEditor control. It was fine with the original EditorWithMask editor. Is there a property I need to change for this event to fire?

Dim num As New Infragistics.Win.UltraWinEditors.UltraNumericEditor
num.MaskDisplayMode = Infragistics.Win.UltraWinMaskedEdit.MaskMode.IncludeLiterals
num.NumericType = Infragistics.Win.UltraWinEditors.NumericType.Double
num.MaskInput = "-nnnnn.nn"
num.SpinButtonDisplayStyle = Infragistics.Win.ButtonDisplayStyle.Always
num.SpinButtonAlignment = Infragistics.Win.ButtonAlignment.Right
Dim btn As New Infragistics.Win.UltraWinEditors.EditorButton()
btn.Text = "::"
AddHandler btn.Click, AddressOf <SubProcedure>
num.ButtonsLeft.Add(btn)
row.Cells(0).EditorControl = num

You need to use the EditorButtonClick event of the UltraNumericEditor. You can't use the Click event of the button, because the event you are hooking is not the event of the button in the grid, it's a clone.
