This property was added to simulate Delphi behaviour where outbound events are not available, so to enable Delphi compatibility set this property to false. The default value is true as this has been grid's behaviour since begining. Normally when user click on a point over empty space after cells for example if grid has three rows but user clicks on an imaginary fourth rowthe currently focused cell will move to the nearest cell to the point just clicked. TODO: the rest of this section will disappear its content will be moved to unit Grids. In general, any Delphi reference about the grids should help us to use Lazarus grids but don't forget that there are several differences between Delphi and Lazarus grids that we have documented with this in mind and as a temporary place for reference information, this place will be used to document things that don't work the same as in Delphi, as well as any new functionality. Entries tagged with need to be set in code, entries can be changed at design time. These adjustments are based in a newly created grid.

Listed below are property settings which will achieve this. You can make a Lazarus grid look like and behave like a corresponding Delphi. We have achieved greater Delphi compatibility as the Lazarus grids have evolved, and this is desirable. However even this was done without attempting to make every single Lazarus grid property or method match its Delphi counterpart.ДЄlso because Lazarus grid internals are very different from Delphi grid internals some Delphi functionality is not possible or needs to be emulated differently in a Lazarus grid from how it would be done in a Delphi grid. At a later stage, compatibility with Delphi's grids became a desired objective and the Lazarus grids started to conform more closely to the Delphi grid interface. When first developed the Lazarus grids were created from scratch without any attempt to make them fully Delphi-compatible. The current grid components differ from Delphi grids in several ways. Why not, let's make a traditional 'hello world' example using the TStringGrid Component. As one of the objectives of this page is to help people with little or no previous Lazarus knowledge let's do a quick starting example of grids in action. Documentation for that grid can be found here.

Given the great variety of information that can be represented, a series of grids exist whose purpose is to facilitate the user in showing specific kinds of information.ДЇor instance, there is a grid designed to show text: the StringGrid. Generally this information consists of text, colors, images or a combination of those three. The type of information that can be shown in a grid varies and mainly depends on what the user wants to show. The most obvious characteristic of grids is that they are composed of cells forming rows and columns. A grid is a component that provides a means for displaying data in tabular format. This text will therefore try to reach the following objectives. It is also intended to serve as a guide for users who have never used grids before as experienced users generally only need a reference for new functionality. I'm using Local InterBase Server, that provides me access to the database.This text will try to show the user some aspects of the grids components in Lazarus. The result of query component is returned to dbgrid. Why is that? Hi pret Recno ,mt Informatio n,0 Table1 is the dataset refered by the dbgrid each time you click the dbgrid then there will be window pop up shows the number of record selected.

But it returns me -1, no matter which row i doubleclick. Commented: Author Commented: RecNo instead of dbgrid.
