Detailed Description

A small specialization of a TextCtrl for numeric input.

This class is a prerequisite for the NumericGridEditor which is an example for a C# implementation of a GridCellEditor. It only allows digits as input. Optionally, a MaxValue() may be specified for the input values. Refer to remarks on BigGridFrame.

Property Documentation

int wx.SampleGrid.NumericInput.MaxValue [get, set]

The maximum value.

This might be null in case of unconstrained input.

new string wx.SampleGrid.NumericInput.Value [get, set]

Sets and gets the text value.

On setting the value: A value containing non-digits will be ignored. If minimum or maximum is exceeded, either a text representation of the minimum is set or the last digits of the value will be selected.
