Numeric Edit Control

Use the Measurement Studio numeric edit control, as shown in

Figure 2-18, to display numeric values and to provide a way by which end

users can edit numeric values. Typically, you use a numeric edit control to

input or display double numerical data instead of using a Web Forms

TextBox control.

Figure 2-18. Numeric Edit Web Forms Control

With the numeric edit control and the classes that interface with the control

you can perform the following operations:

• Perform range checking.

• Set the minimum range value to negative infinity and the maximum

range value to positive infinity.

• Create custom formats or use built-in numeric formats including

generic, engineering, and simple double. You can use these numeric

formats with other Measurement Studio user interface controls, such

as the waveform graph and numeric pointer controls.

• Connect to a Measurement Studio numeric control so that if you

change the value of one control, it changes the value of the other

control.

• Set the coercion mode property to discrete or continuous values. This

property configures the control to allow entry or display of either a

discrete set of values or any value.

• Validate and format data without posting back to the Web server.

Tip For more information about using the Web Forms numeric edit control, refer to the

NumericEdit Class section in the NI Measurement Studio Help.
