Infragistics.WebUI.WebDataInput的InputMask属性说明

官方网站说明

Default value is set to "CCCCCCCCCCCC".

The mask may contain literal characters and input-mask-flags such as

• & - any keyboard character (entry is required)
• L - letter (entry is required)
• 0, # - digit (entry is required)
• A - letter or digit (entry is required)
• C - any keyboard character (entry is optional)
• ? - letter (entry is optional)
• 9 - digit (entry is optional)
• a - letter or digit (entry is optional)
• > - all letters to the right are converted to the upper case
• < - all letters to the right are converted to the lower case

For information on how to customize input masks, see the following topic section of the help: Developer's Guide > The Toolset > Controls and Components > WebMaskEdit.

Notes:

• If in front of any flag-character appears the "\" (escape) character, then that character becomes the literal part of mask. For example, if mask is set to the "A\A\BB\\##\99" and control has no data, then text in edit mode will appear as "_A\BB\#_9_". Where the "_" are available positions for entry.
• To cancel upper/lower case convertion which was set by the > or < flag, that flag should be used one more time. For example, if mask is set to the ">CC->CC->CC" and user entered the "XxXxXx", then resulting text should appear as "XX-Xx-XX".
• While control has no input focus, the optional empty mask positions are not displayed.
