Allows setting the number of records to be loaded by the grid or free style grid in Web and SD Panels, or the number of empty lines in Web transactions.
control. Rows = number
Any positive number or zero (Unlimited).
The effect of Rows = 0 (Unlimited) is the following:
- Rows = 0 (Unlimited) in Web Panels as well as in SD panels, indicates that there will be as many lines displayed as records resulting from the associated query.
- The 0 value in Web Transactions indicates that there will be no empty lines in the grid.
||Indicates the number of empty lines to be shown on the grid.
|Web Panels and SD Panels
||Indicates the number of records to be loaded in the grid. Zero means all the records.
When Rows is set to a value different than zero (unlimited), it's assumed that some type of paging is going to be implemented for the grid. Paging type can be automatic or manual.
For SD apps, Infinite scrolling is always performed and the Rows property determines the page size of the grid which is brought to the client. Data is brought to the client on demand, as the user swipes (up or down) in the grid.
For Web applications, when the Rows property is set to a value different than zero (unlimited), the Paging Property for grids is enabled, so the user can decide if the grid will show paging buttons or if it will perform Infinite scrolling. Infinite scrolling is supported for the Abstract layout only.
This property applies both at run-time and at design-time.
To allow the end user to enter lines one by one in a web transaction, you can set this property by combining it with the AddLines Method at execution time, as follows:
if &Mode = 'INS'
Grid1.Rows = 1
else // &Mode = UPD / DLT / DSP
Grid1.Rows = 0
EndEvent // 'Addlines'
Then, the end user can press the AddLines button in Insert Mode to add empty lines one by one to the Transaction.
