Problem to clear lines

[srichter]

Hi guys,
I have ComboBox with some elements in it. When selecting a different item I access a database, load a related record and update some edit fields accordingly. I also have to load some lines into a JQMemoEx field which works fine. What I don't get done is clearing the existing lines before loading the new ones.

The strange thing is that I can use eiter JQMemoEx.ClearLines as well as JQMemoEx.Lines.Clear - both don't seem to work when excuted on the OnChange event of the ComboBox.

Any ideas?

Best regards,
Stefan

Hi Stefan,
Do you use ComboBox or ComboBoxEx?
Async or sumbit event?

Hi Stefan,
Please, check the demo in attachment.

Hi there,
Thanks for the demo - it works fine.

I use the same event, and the same MemoEx routines beside the fact I'm not adding a single line but loading from a MemoryStream. But that should not affect the ClearLines, should it?
But still it doesn't work in my code...

Best regards,
Stefan

Can you send us the sample demo with that issue?

Hi guys,
I have to appologise: it was actually at my end and not with your components at all!

On the change of the ComboBox I load a new record from a database which contains some text for the MemoEx. This loaded into the MemoryStream. The issue actually happend because I didn't clear the MemoryStream before loading a new record. I took the code from a different project where re-loading wasn't possible - so I was always sure it was empty since it was re-created everytime. Clearing the MemoEx was fine all the time.

Thanks a lot for looking into this anyway.

Best regards,
Stefan
