Empty list after setitemlist()

[szternakb]

Hello,

I'm a bit newbie in this forum but i did not found any older topic related to my problem.

In the middle of my small application (in a list.onselect() function if it matters) i want to set the items in a list with the setitemlist() function. The source is a public stringlist variable. The application is collecting items to this stringlist then everything was ok, populates it to the list. However the list after the insertation seems to be empty but if i select one item with the stylus the selected item will be visible. Also if I'm using the arrows to scroll down/up the list will be visible.
I'm also using an other list but it is filled in the form.OnOpen() function and it is working wihout any problem.

Is there any good medicine to solve this problem?

Thanks,
Barna

Try list.redraw() after setting the items.

Try list.redraw() after setting the items.

Sorry, i did not mention it, but i tried the redraw function and it did not help.

Ohw.. sorry about that.

That is weird.. are you sure you redrawed the correct list?
Can you post the source code?

Sure,

Here i'm collecting the items into "stationsb" which is a global stringlist variable.
sbtemp contains a large, comma separated text, buff, buff2 and temp are string buffers

if (strlen(sbtemp)>0) {
temp=substr(sbtemp,0,strlen(sbtemp)-1);
buff=substr(temp,0,strstr(temp,";",0));
buff2=strright(temp,2);
stationsb.add(buff);
extratimeb.add(buff2);
}

Here i'm updating the list:
list1009 is the list what not refreshing automatically, push1004 is a push button to select between stationsa and stationsb. Stationsa is another string list with different elements.

if (push1004.checked) {
list1009.setitemslist(stationsb);
list1009.redraw;
}
else
{
list1009.setitemslist(stationsa);
list1009.redraw;
}

I also checked the stringlists' content with a simple alert() and the strings are seems to be ok. The problem is just with the redrawing / refreshing.

redraw() is a method.

Calling

Code: Select all

list1009.redraw();

should work.

PS Don't forget the brackets () !

Please believe, redraw() is not working in my case. I can send you the application...

Thanks for the help, Percival. Brackets were missing after redraw. After i use redraw() it worked well. It is interresting that both redraw and redraw() is working and doing something else...
