How to determine cell width based on cell contents?

[sliuParticipant]

I meant how to calculate the width of a column so that when creating Spreadsheet via OpenXml the column width could be set reasonably.

Thanks!

I personally haven’t done it, but the links are better than no answer.

In these two posts, they already knew the width of the columns. My question is how to determine the width of columns. For example, I have a string “Try this link as a starter”. What is the column width that can show all the words in the cell.

Thanks for replying

You didn’t read far enough:

There, you have your widths. Go back to your code and plug that in. Tada, mission accomplished.

“Wait, so why can’t those widths be calculated?”

Well, they can. I just think the effort’s not worth it. First, you need to know the font of the text in that cell/column. Then there’s some weird truncation calculation based on the width of characters in that font… You know what, here’s an extract from the Open XML SDK documentation:

width = Truncate([{Number of Characters} * {Maximum Digit Width} + {5 pixel padding}] / {Maximum Digit Width} * 256) / 256

Ok, got it. OpenXml has the calculation.

Thanks!

You are welcome! I am still learning it myself…
