Question

How to increase the datawindow row size dynamically

Asked by: gajmp

I have one composite datawindow. In that three DW are there.
First DW contains the company name and address.
Second DW contains the peoject description and cost of the project.
Third DW contains the total cost of project, overall time taken and other details.
All the above three DW have detail part only

My requirement is
1. When we print the report then the thrid DW should be bottom of the page (even that there are one project then this DW should be in the bottom of the page)
2. In second DW, some project description will go more than one. That time report system should adjust the hegiht automatically. If the project description end within a line then the second project desc should start next line itself.
3. If the report goes to more than one page then first DW should print on each page begining and the third DW should print in the bottom of the last page.
4. If the reports goest to more than one page then the bottom of each page should print the page number..

I tried like below
1. third DW should print at the bottom of the page - I have add dummy UNION ALL SQL and restict the number of rows to 24 in the second DW and set the visible propert as 1 when the length of project description as greater than 0.
if we are not set autosizeheight then its working fine for the 24 projects. if the projects more than 24 of If we set the autosizeheight property true then report not coming properly.

2. I have check the autosize height of the detail band and for the project description column. If we did like that then the system actual size of the column size (as per the DB table definition). so if the project desc is one line then alson two or three blank lines are there and then the second project starting. But I dont want this extra blank lines.

3. I dont have any idea about this.

Please guide me to sort out this problem. It is very urgent.

For #1, can you try putting your third datawindow in the summary or trailer band ( See which one suits ur requirements better))
For #2, have you tried "Trimming" the data during retrieve ( I am assuming it's a CHAR field in the database and not VARCHAR)
#3, Same as #1, try adding DW1 to the header band...

 

by: sandeep_patelPosted on 2009-09-04 at 21:29:14ID: 25264949

I would suggest....
a. try to create a single datawindow with joins and group
b. along with autosize also set to slide all columns above and make detail band height to 0

Sandeep
   I am using 4tables. in that 2 tables are master and the 2 tables are transaction table.... volume  of data will be more in these 2 transaction tables. so if we join all the table it may give perf issue.. dats y i hv split it into three DW.

first DW will fetch data from master table
sec DW will fetch data from one transaction table
third one will fetch data from another transaction table...

thanks for ur comments

I have solved mostly by did like below
1. put the first DW in the header band and uncheck the autoheight and check the newpage property
2. Sec and third DW in the detail band
3. check the autosize height of detail band in sec DW amd check the autosizeheight for the preoject description column.
4. I am using few vertical lines in the sec DW so add rowheight() in the Y2 of all the vertical lines.

now its wrking...
Actual requirement is
thrid DW should come bottom of the last page
first DW should come each page begining
sec DW will looks like invoice..
sl. no    Project description    cost
so three column...thats why i have added vertical line. its woking fine nw...

if the reports goes to more than one page then the each page end should show horizontal line and then comment lik "coninue in next page" -- I DONT KNOW HOW TO DO THIS

some time this sec DW will contain only one project that time, report should show header (first DW) bottom of the page third DW and in between the sec DW should show.
So i have add UNION ALL with one dummy SQL... (this dummy sql will return around 30 rows) so actual rows + 30 rows.

If the number of project is one or the all the project descrition can complete within one line then my report showing correctly. if the project description length vary then it is unnessarily going to next page. I dont know how to control this.

please help me to solve this

Thats simple, i solve this but are to relative,
make the DWs too lite in height, like 6pints in properties area,
Then put the others dws above too near one to another
And make the band detail  height resisable.
