NumericUpDown with decimal digits ?

[robert bergelson]

Is there a way to get a cell of type NumericUpDown to performs edits at granularity finer than integer units ?. By this I mean is there a NumericUpDown renderer which can show decimal digits and click up/down in units of .1 or .01 or .001 etc. ?

The standard control requires ints, but you can derive a similar control that uses doubles. Attached is an initial try at it.

Thanks Clay !. This is what I needed.

Clay,
In the example you provided, the result is not saved to the cell once the cell looses focus. How do I change this behavior ?

In the FNumericUpDownCellRenderer.OnSaveChanges method, right at the bottom, add this code:

if(ok)
	ok = base.OnSaveChanges();

return ok;  // line already there...
}
 Copy

This should allow the changes to be saved.

Could you send me the sample? Thanks
