Using a variable listview with images. This listview looks at a temporary table to select paid invoices. My problem that I am having is that when I issue a REFRESHLIST (which is required due to the images) I am taken to the top of the list which is undesireble.
Jan, The REFRESHLIST command is doing exactly what it is intended to do, i.e., to refresh the data set associated with Variable Lookup ListView.
Trying to figure out a way to return to the last position but am not getting the syntax right. Client unhappy.
Oh no. I'm really sorry that your client is unhappy. That's not good. However, is it R:BASE's fault that your client is not happy? Does your client know that you have not implemented the functionality and have forgotten the most important step? Well, ask and you shall receive! What you need to do is, first find the TOPITEM for the last selected row (item) in the list (using GETPROPERTY command), and then use the REFRESHLIST and TOPITEM (using PROPERTY commands) to achieve your goal. The typical implementation of a feature to retain the last selected item as well as the top item on the list when refreshed would be as following: A. Find the top item on the list before refreshing the list GETPROPERTY <VarListViewCompID> TOPITEM vTopItem B. Now refresh the list PROPERTY <VarListViewCompID> REFRESHLIST 'TRUE' C. Keep top item exactly the same before refreshing the list PROPERTY <VarListViewCompID> TOPITEM .vTopItem This technique should give you the results you want. Client Very Happy! Here's a sample application to demonstrate the use of such feature in R:BASE 7.6, C/S:I 7.6 and Turbo V-8 for Windows. http://www.razzak.com/sampleapplications/ Sample Applications: Using TOPITEM Property in ListViews Use this sample in conjunction with RRBYW14 database. Enjoy and make sure to have fun! Very Best R:egards, Razzak. PS. Make sure that you are using the latest updates of RBG76 or RBG8. http://www.rupdates.com/AuthorizedDevelopers/
