Hello,everyone!

I am a beginner for VB.NET and dhtmlxGrid.In my project(Web Application) here is a page to do as follows:

①Click button『Search』 to get datum from table(A) and to show the gotten datum in the dhtmlxGrid.
②Click button『Add』 to add a row into the dhtmlxGrid and edit the added row.
③Click button『Del』 to delete the selected row to the in the dhtmlxGrid
④Click button『Update』 to edit the selected row in the dhtmlxGrid
⑤Click button『Save』 to save the modified dhtmlxGrid datum to the table(A)

In order to get high efficiency,I use Ajax to do as follows:
-->②Click button『Add』 to add a row into the dhtmlxGrid and edit the added row.After editing, I save the added row ith the flg(1:added) to sesson.
-->③Click button『Del』 to delete the selected row in the dhtmlxGrid. After deleting, I save the deleted row with the flg(2:deleted) to sesson.
-->④Click button『Update』 to update the selected row in the dhtmlxGrid. After updating, I save the edited row with the flg(3:deleted) to sesson.
-->⑤Click button『Save』: I use the datum from session to update the table(A)
a)added row ----Insert it into table(a)
b)deleted row ----Delete it into table(a)
c)edited row ----Update it into table(a)

The above way is OK? Second way?

Thank you very much!
