CVI table control - preallocate rows?
Hello,
We are using a CVI table control to display test steps as part of a custom test sequencer. We have varying lengths of test sequences. A row in the table control is basically a test step in a sequence.
Is it a correct assumption to preallocate the maximum number of test steps we will encounter at application startup using InsertTableRows? (In our case it is around 60K rows)
I'm assuming that performing DeleteTableRows followed by InsertTableRows whenever a new test sequence is loaded could cause peformance issues involving possible memory fragmentation.
Thanks,
Hello Sirs,
I have also the same of slowing problem, when I try to fill some data in CVI table.
If I try to add 50 (TBC) rows, 4 columns, the fully data display seems to be correct.
If I try to add 1000 rows, 4 columns, the fully data display take several seconds (30s to 1 min) !
I try several computers (Core 2 Duo to i3) (XP pro to Seven 32 & 64), same problem.
In the past, I have the same problem with Labview.
A NI guy gave me a VIs (FA) property, to permit to delay the refresh of the control latter.
Like this at each new adding, they was not have a refresh requested, so the filling was fully more quick.

Table Control Enable / Disable Row
Hi,
I have a table control with 6 columns also screen contains some header input fields.
Out of 6 columns first two columns are disabled.
Depending on value entered in certain field in the header I fill the table control. e.g. if the value in certain field is X, table control is filled with say 15 rows, if value is Y, table control is filled with say 5 rows.
Now my requirement is only those rows which are filled should be disabled. i.e. If user chooses value Y then all rows after 5 should be input enabled.
But since I have disabled the columns statically complete column remains disabled.
Can anybody tell me How to enable a particular row in table control ?
Thanks n Regards,
Nitin

You screen structure is SC_ITAB.
Your internal table is ITAB.
In PBO of screen

In ABAP Module

please give me solution
main problen is how can know inserted line in table control and pass that data into ztable.Hi,
Follow the below logic,
PROCESS BEFORE OUTPUT.
MODULE STATUS_0001.
MODULE POPULATE_TABLE_CONTROL. --> Get the data from table store in
ITAB
LOOP AT GT_CTRL_LP_D516 INTO GS_WA_CTRL_LP_D516
WITH CONTROL CTRL_LP_D516
CURSOR CTRL_LP_D516-CURRENT_LINE.
The following module moves data to control
MODULE MOVE_TO_CONTROL.--> Move data from ITAB to table control
ENDLOOP.
PROCESS AFTER INPUT.
LOOP AT GT_CTRL_LP_D516.
ENDLOOP.
MODULE EXIT AT EXIT-COMMAND.

How to delete a row in table control(accepts only input)?
Hi All,
I have an empty table control which is only use for data input(this data will then be use to store information to a custom table). I have two buttons, Create Entry and Delete Entry.
In my screenPainter for the table control, I have the checkbox w/SelColumn ticked and assign variable T_DATA-MARK on it.
Please see the actual screenshots and code below:
The aim of the table control is just to accept inputs, so the internal table in the PBO is always empty.

This is the sap doc answer for you question regarding LINE.
Controls the scroll bar of the table control. At LOOP without internal table, LINES has the initial value zero and must be set in the program so that the scroll bar can be used. At LOOP AT <itab> the system sets this component to the number of rows of the internal table, whenever the table control is processed for the first time. The initialization event of a table control is not determined uniquely. If the corresponding internal table is not fully created at this event, then the LINES variable receives an incorrect value. If LINES in the LOOP loop is smaller as the number of rows of the internal table, then the table control contains blank rows at the end.
Therefore you should always set the LINES component explicitly in the ABAP program, including at LOOP AT <itab>. In this way you have full control over the dimensions of the vertical scroll bar and so can control the number of rows that are ready for input. Initialization should usually occur at PBO directly before the LOOP statement for the table control. -
Processing of Rows in the Non-visible area - Table Controls
Hi,
I have a table control. At any given point on the screen the table control displays 17 rows. now there is a functionality thru which the user will be able to paste some values into a particular column of the table control from the clipboard. Then the user will press save to save all the data on the table control into a DB table. the problem is the rows that are not visible on the screen i.e. the rows that has to be seen by scrolling the table control. while looping the table control these rows are not getting looped i.e. the looping ends with first 17 visible rows. how do i make the table control loop at the remaining records also?suppose, your table control name is 'table0'
and you declare it as :
'controls table0 type tableview using screen 100.'
so to process all rows of this table control you should assign for it
'table0-lines = n.'
where n is row count that you know.
then you can use following statement
'LOOP AT <internal table> CURSOR <scroll-var>
[WITH CONTROL <table-control> ]
[FROM <line1> ] [TO <line2> ].
...<actions>...
ENDLOOP.'
result: all n rows will be processed. in your case n is greater than 17. -
Different values in a list box for each row of the table control...
Dear Experts,
Is it possible to populate different values for each row in a listbox inside a table control ?
Example,
Row 1 in the the table contains A, B & C
Row 2 in the same table contains C, D & E
If yes, How?
yes i am using
call function 'VRM_SET_VALUES'
exporting
id = i_name
values = i_list.

Changing number of rows oin a table control dynamically
Hi all
Is there a way to change the no of rows dynamically.
I have a requirement that at run time , depending on a condition, I have to change the no of rows in the table control to 1 row.
Is this possible to do?If else How?
Thanks.You can redefine table control attributes eachtime PBO is called, because those attributes are dynamic. So although you defined tc-lines as 1 in first PBO execution, you can redefine to 2 if some condition is achieved,
One idea could be to create a global var, called tc_lines which is initialized as 1. In your PBO you shoud use: <tc>-lines = tc_lines.
In PAI, when you obtain your condition, you shoud here add or subract one from this global variable.

first read the table control internal table line and check whether the field is filled if the field had value make it display mode else make it input filed..

Module Pool table controle row level prob
Hi Experts,
I am working in a module pool program where in table controle i want a perticular row should become in display mode if a specific field is NE SPACE. is it possible if possible than please sugest me how.
Thanks and Regards,
D Tarun KumarIn this case all the rows will be in display mode
Exactly My Requirement I am describing with example
Suppose in table control I have three Records and the first field is main field which is if initial than the row should in change mode otherwise is should be in display mode.
Field1 Field2 Field3 Field4 Field5
1abc2 1abc3 1abc4 1abc5 Record 1
2xyz1 2xyz2 2xyz3 2xyz4 2xyz5 Record 2
3pqr2 3pqr3 3pqr4 3pqr5 Record 3
So here the second rowu2019s first field is not initial so I need here in table control the second row should be in display mode and next first and second row should be in change mode.
Now You tell me is it possible or not if possible than please suggest me what I have to do
Thanks & regards,

How to make a table control header become two rows?

May I know how to make the static header/label rown in table control on screen become two rows?
As we know, normally a table control's first row is header, and starting from the second row onwards are it's content or data. So, now I would like to make the hedear/label become first two rows.
Anyone know about it?
