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 Delph,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 inputed ?
Some developers told us that they can'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.
