ALV using classes

Former Member — Mon, 08 May 2006 17:06:44 GMT

Hi all,

I am using ALV grid display , using classes .

The problem I face is, when the user hides some fields and send the list to spool or gets into the print preview

some of the header info , top_of_list parts Stripped away ,The top of list adjust to the alv list width or sets to maximum 80 .

I want the top of list to be in a fixed length ..

for ex : 255 line size , in the spool.

Any body know how to set <b>min_linesize</b> parameter

of layout from the classs ,CL_gui_grid* or cl_salv* ..??

I checked the documentation of Serdar Şimşekler, and it says ..in section : Piece of Troubleshooting .

Its line-size is restricted so.

Try to change your page header layout.

1. Is it possible to over come this in some way ?

2. is it possible to get the list width at run time ,

ie ,in user command event on print preview ??

Thanks a Lot ,

Hi Freney

I've never tried this before but there is a public method in cl_gui_alv_grid called SET_FRONTEND_PRINT which has a parameter IS_PRINT. One of the components of the structure LVC_S_PRNT (which is what is passed into the parameter) is NO_COLWOPT. This prevents column width optimisation when the grid is printed - it <b>might</b> solve your problem.

IS_PRINT is also a parameter for the method SET_TABLE_FOR_FIRST_DISPLAY, if you are already using that.

I hope I have understood your problem correctly and have provided an avenue for you to explore.

Kind regards

Andrew

Hi Andrew ,

Thanks for your reply,,But my problem is not related to colum width optimization .

poblem : The header , top of list ' can not set to

a fixed charactor lenght for ex -255..

If the list , ie the lenght of data in the internal table, which is set to visible is less than 80 char lenth , the header ( top of list ) is limited to 80..

Thanks for any help.

TRY SETTING PRINT PARAMETERS IN LVC_S_PRINT AND PASS THAT TO IS_PRINT OF SET_TABLE_....._DISPLAY .
