I have a label that is showing several lines of text. With a text box I can turn off multiline, which does limit the text shows, however it will only show 1 line of text. Is there a way to wrap that to more lines? Can this be done with a label instead?

I would the output to look like this? 3 maybe 4 lines of text followed by 3 periods.

text text text text text text text text...

You will not get this with a TextInput control, but a label will do what you are asking for.

I hope this is helpful for you.

How would you achieve this. As of right now all of the text shows in the label. It only gets cut off my the height of the label.

For the most part, you would turn off the Wrap option and you're only going to get overflow for each line of the text. If you have multiple lines in the text, they will all end with three dots. If a single line, it will be one line ending with three dots.

In other words, the label will not wrap and not wrap - it will not wrap to the height of the label and then not wrap from there.

Thanks Randy. It's not ideal since I'd like to wrap to fill the label and only add the dots at the end when the text doesn't fit but I guess this will do for now. FYI. I couldn't get multiple lines to end with 3 dots. All text seems to get compacted into a single line.

Yes, unfortunately, that will not happen that way with the control.

Don't forget though, you also have the Overflow - Scroll option that you can use if you can do away with the 3 dots concept. This will make the label scroll if there is an overflow. Not sure if that helps in any way, but just wanted to make sure you were aware of it.

I did try that but it doesn't work well with a gallery. My gallery is really for preview and not full records. That is what I use a display form for.

Like I said...not sure if it helps. I just wanted to make sure that you were aware of it in case it would have actually helped.

Left(ThisItem.Report,150) & "..." the 150 characters is the max I wanted to display in the Body section of the gallery.
