详细说明： DBGridPro features list RAD-Studio technologies support TDBGridPro is one of the basic components included in the RAD-Studio suite and supports all RAD-Studio concepts. Multilevel layout of column titles - fields of dataset record can be represented as several rows in the grid to enhance the display of information to end-users at runtime. Column layout can be easily set by drag&drop operations in design-time and run-time as well. (screenshot) Run-time column selection - your end-user can select to show necessary columns and hide needless ones. (screenshot) Save grid layout at run-time - call single method to get all grid settings, including column layout, as text string. Then it is possible to save the string anywhere: file, Windows registry, database field, etc. So, you will be able to restore the settings at any time. (code sample) Automatic column fit - in this mode grid columns retain position and proportion when the grid is resized. Fixed columns. (screenshot) Grid footer - ideal place to display summary of columns. (screenshot) Mouse wheel support. OwnerDraw support for most grid elements. Automatic incremental search - your end-user can easily locate necessary records in the database. (screenshot) Drag & Drop. Optimal (flicker free) painting. Smart scroll bar. Standard and extended MultiSelect - several records can be selected with CTRL and SHIFT keys. MS Excel® - like style coloring of selected records (optional) (screenshot) Visual attributes for rows and cells - you just set the value of some properties and specified rows and cells are colored different colors, displayed in various fonts. All this is possible without tiring manual coding. (screenshot) Total control of user input - every user action can be controlled via vast number of useful events. DBGridPro designers concept The Designer is a mechanism by which you can easily abstract the design of your DBGridPro controls. This type of abstraction has the following benefits. First, via Designers, you can allow your end-users to change the look and feel of your applications at runtime. Secondly, the Designer helps you standardize look and feel of all data grids application wide. Finally, evolutions in the appearance of user interfaces can be implemented easily and without having to trace through all the DBGridPro controls.The Designer lets you control each aspect of DBGridPro control. For example, you can specify the color, style, and font for every element of the grid, define the type and style of lines. Enforcing application look and feel standards is much easier using the Designer because it can be used as the central repository for your project‘s standards. When standards change, simply change the settings of the Designer. The Designer provides a single point of reference from which DBGridPro controls retrieve their visible attributes. Ultimately, the Designer guarantees that you can build an UI that reflects the appearance you need. ...展开收缩
