Very slow performance when assigning value to a form item

Question

Dear all,
I have an add-on form that contains 30 text edits. I did not creat the from with screen painter but positioned them by marking each item's top and left position in the new sub.
I have named them as 'edBox1', 'edBox2'......, 'edBox30'
At a point I need to assign value to each edit text, I have queried the content from DB into one recordset. However, when I start to assign values to each edit text, the performance became very slow.
my code is as follow
me.form.items.item("edBox1").Specific.String = recordset.field.item(0).value.tostring
me.form.items.item("edBox30").Specific.String = recordset.field.item(29).value.tostring
I found that B1 seem to iterate each item on the form in order to find the item I specified.
so I think I should specificy items earler.
Now for each item I dim an object for it at new sub
Dim oedBox1 As SAPbouiCOM.EditText
Dim oedBox30 As SAPbouiCOM.EditText
and while creating forms, I specificy each item to the matched object
Then I assign values to items by
oedBox1.String = recRetrive.Fields.Item(0).Value.ToString
oedBox30.String = recRetrive.Fields.Item(29).Value.ToString
However, B1 still iterates to find the item and the performance is still slow, does anyone has a better solution to this issue? please kindly advise.
Thank you
Alan

Hi Chen,
you can find one example under SDK samples which will guide on using datasources
Bind the controls to dbdataource and then query the datasource.
then update form using oForm.Update(),this will automatically fill the values in all edit boxes and it will be very fast as well
Hope it helps you
