How to Round Corners for Paragraph Background Pinstripes in InDesign

[dublove]

Paragraph pinstripe(backgroud): is there any way to make these two corners automatic rounded corners?

carriage return？

That's too much trouble, there's a lot of it.

Create a paragraph style. 

[Scott Falkner]

Not that I can see. Odd, since there is an option for paragraph rules. Click on image for enlargement.

If you look carefully at the corners you will see the shading has sharp corners at the bottom but the rules do not. 

It looks like you will need to create two (or maybe three) styles: one for paragraphs that don’t span column breaks, and one for those that do (or perhaps one for the paragraph at the bottom of the column and one for the paragraph at the top of the column. You will have to insert paragraph breaks where necessary and the alternate style.

Alternatively you can use paragraph rules instead of shading and turn on “Display Border if Paragraph Splits Across Frames/Columns,” which is what I did in the above example.

My example is two text boxes.
The first one at the end of the text box and the second one at the beginning.
I'm using a paragraph background.

If it is a paragraph flowing from the one to the other, then not having it rounded is a more clear signal to the reader that they are in the middle of the text. If the corners are in the middle of a paragraph this is reasonable.
If  you add a return at the end of frame one it will mean you get round corners in the right column. 
Another alternatives is to have the frame itself with the same rounding and, use "clip to frame" 

[Mike Witherell]

Add this to your paragraph style: Turn on Keep Options > Keep Lines Together > At Start/End of Paragraph: 2 and 2

I don't know why it works, but it works.

carriage return？

Yes. Paragraph shading is a Paragraph format, so you would have to end the paragraph with a return.

An Object Style applied to the text frame might be better:

Hi rob day~

Thank you very much.

Controlling with object styles is a good way to do this.

It's just that I have other paragraphs in the same text box that don't need underlining.

I remember what I used to do:
Hit a carriage return at the very top, or bottom of the page to make a paragraph.

It's all a pain in the ass.
