dbgrid, flexgrid,or datagrid?

Performance wise, which is the best- DBGrid, MSFlexGrid or DataGrid. what is the difference between the three?

Thanks

Performance wise, I haven't a clue. Certainly I have never noticed a significant difference (and I have used all three at one time or another). As to other differences, the DataGrid is primarily intended to display records from a Microsoft Access or SQL database, whereas the other grids are more for spreadsheet-like apps.
The only differences between DBGrid and MSFlexGrid that I have noticed are the version of VB that provides them, and differences between available properties and methods. I can tell you that I have found (for various reasons) the FlexGrid control annoying and still use the DBGrid when I use a non-bound grid. But that may be merely personal preference. One note I CAN provide on performance: if using a DBGrid, with very large tables (say on the order of 100,000 records), you will see a HUGE difference in performance if you open a table recordset rather than a query recordset. I never use snapshots: I don't know what that performance would be.

hello,
if i just wan to show some words insides grid, which one is suitable
and for ur information, words from system , not from database or tables

thanks in advance

If your intention is simply to show words and not bind the grid to a database, there is really no question: you need to use either the plain 'ole Grid control or the Flexgrid control. I personally prefer the plain control as I've gotten frustrated with various aspects of the Flexgrid control. Despite an error in my reply to the original letter, where I didn't notice I'd said I use the DBGrid control in non-bound applications (I meant the "Grid" control--no qualifier), there is no way I've found (though some more clever person might know a means) to add columns to a DBGrid beyond the original 2 columns it sets up automatically. This grid control must be bound to a database at design time and the "Retrieve Fields" function performed to create more than the 2 default columns. By contrast, the number of rows and columns in an normal grid control can be set either at design time or programmatically. In fact, the sort of non-bound use you describe is exactly the raison d'etre of the grid control.

I hope this answers your question satisfactorilly.

Lothar from this forum has an excellent example of using the DBGrid in 'un-bound' mode using disconnected ADO recordsets - take a look at :
