Frequently Asked Questions
1.Why can't EasyGrid print grid line?
Generally, EasyGrid doesn't print any background lines, but lines drawn by DoDrawLine EasyGrid will be printed (make sure you've enabled it by uncheck the "print grid lines" option). For more information, see EasyGrid Spreadsheet.

2.Why can't EasyGrid refresh?
When evaluation time is expired (30 days), EasyGrid will not refresh. EasyGrid adopts this method and thus won't make your application corrupt (that's a bad manner).

3.How to make self-defined function wizard?
Refer VCDEMO source code please, there is a example there.

4.Why can't EasyGrid refresh after I changed some data?

5.Can I use EasyGrid in Windows NT?
Yes, but you must run Trustsoft\OCX\exe\Ntdrv.exe first, this program will install device driver for NT, and then restart the system.

6.How to upgrade the EasyGrid Control in my project?
When you get a new version of Control, and want to replace the old one in your project, there exists two cases: you just need do nothing if you use VB or VBScript , all the new methods and events will come out automatically; But if you use VC or Delphi, you have to delete the old Control in your project and then insert the new one.

7.Why can't I get the data which users inputted ?
Some developers told us that they couldn't get the data which users just input by using GetEasyGridData(),. The reason is: EasyGrid Control will save what user's input when KillFocus event occurs, but when user clicks a button, the click event will occur before EasyGrid's KillFocus, so the input string can't be obtained in the click event. The solution is to use SetFocus,  which can cause EasyGrid KillFocus event and then you will get the input data .
Same problem is shown in any other control.

8.Why is any EasyGrid pink with shadow?
Which means that this EasyGrid is read-only. And red means that is a formulae. you will not see this in print.

Certainly. There are some problem on DoSetEasyGridData(), for PB5 and PB6 don't support the Chinese characters' parameter of ActiveX , we need to do some adjusting on DoSetEasyGridData() .
