Michael,

I would suggest to create new Z dataelement of length 255 and attach it to your requirment.

AMit.

No, I already have my field as char 255. But in my dynpro only 117 char will be visible.

You're screen will need to be more then 255 columns wide such that you can put a field of that length on the screen.

Generally this his handle by flagging the wrap option on so that when the user types and hits the end of the visible area, they can continue to type without the loss of data up to your 255 length.

Furthermore, if you are trying to change the length of this field dynamically, you would still need to have the screen more then 255 columns, but then, you can change the length in a LOOP AT SCREEN loop and when it's this field, set the SCREEN-LENGTH value to 255.

Can I enlarge the textbox on 4 columns and if it is possible; what should I do exactly?

[Former Member]

4 columns? are you asking if you can break the 255 field into 4 columns? I guess you could, but you wouldn't get the text to jump from one field to the next.

4 rows? Well.. not as a text box. I this case you would need to create an text editor in a Custom control and store the text in an intenral table until you wanted to combine it and move it to your single storage field. Only potential issue here is that I'm not sure you could limit it to 255 characters. I know you can protect areas of the edit box. Perhaps you could set the protection from the 256th position to the end to the text box.

I have now a Custom control, but where I can create a text editor in this?

In your global data area.

From another program of mine, where you would need to change the g_editor# value , this can protect where the user can change areas of the text editor. This one goes from the beginning of the box to the last position of text already there. You would need to modify to have it after the 255 postion of the box.
