Tip of the Day: Using Multi-Select Option for ListView Control
Supported Versions:
. R:BASE 7.6 for Windows (Build: 7.6.1.30316 or higher)
. R:BASE C/S:I 7.6 for Windows (Build: 7.6.1.30316 or higher)
. R:BASE Turbo V-8 for Windows (Build: 8.0.15.30316 or higher)
Did you know that now you can use the multi-select option for
Variable Lookup ListView control in forms?
Here's how:
Form Designer | Variable Controls | Variable Look-up ListView
Variable Look-up ListView | Object Property | Effects | MultiSelect
Notes:
01. To use the multi-select option, make sure that the variable
data type is pre-defined as TEXT, NOTE or VARCHAR, depending
on the anticipated, cumulative values for the variable.
The TEXT variable length is limited to 1500 characters, NOTE
variable length is limited to 4092 characters and the VARCHAR
variable length is limited to 256MB. Use the data type wisely.
02. Use single-click to select one item.
Use [Ctrl + Click] to add item(s) to the list
Use [Ctrl + Click] to un-select the already selected item
Use [Ctrl + A] to select ALL items
Use [Ctrl + A] to un-select ALL items
Use [Shift + F6] key to select ALL items
Use [Shift + F6] key to un-select ALL items
03. All key values will be separated by a comma.
An application to demonstrate the practical use of this new feature
is included on RBG76 Super Advanced Training CD.
