It is hard to implement following internal behaviour of the control. But I have used it earlier in other language, and it was nice behaviour when there were many records in the related table. Here we need to use JavaScript/Ajax to implement this. And maybe an index on that field?
Once user pressed a key inside the control, a SELECT TOP 31 ... WHERE Field startsWith TextBox.Value command fired. If it received 31 records, there was no reason to show list. If it received 1-30, the records show in the list. The color of the textbox can change for f.e. 0, 1, 2-5, 6-30, 31+ records. If this is to implement, there is additional problem, that there are languages with double-chars letters like 'ch', where we can f.e. receive 0 records for 'Loc', but 1+ records for 'Loch'. :-)) On 31 led, 21:41, Massimo Di Pierro <massimo.dipie...@gmail.com> wrote: > The rationale is easy.
