Maximum test field length

[tom_garvin]

I have a client who wished to paste in large chunks of text, typically copying from an Excel worksheet, capturing in a varchar(max) column in Azure SQL DB.

It looks like PowerApps accepts all of the text, saves it, but in SQL Server we find that we only have 10,000 characters, a suspiciously round number.

I found an advanced setting which indicates inheritance from a parent, and I overrode that with a hard number, 120,000 to start with, and the app runs just fine online. I have not had a chance to test on a mobile device.

If it works, it works, but regardless, if there is a list of known limits, I'd appreciate a link.

Hi @tom_garvin,

I think the text limits should be mostly related with the Data Source.

For the Varchar(max), please check:

Char and varchar

When it comes to the control within PowerApps, specially for the TextInput control, it should have the MaxLength property for you to restrict with the Max length that a user is allowed to enter.

For more information, please see:

Text input control in PowerApps

It looks like there is a limit of 10,000 characters for a text box even if you set max length property higher than 10,000.

We have found that the work around for this is to change the text box "Mode" property form single line of text to multiple lines of text. This setting seems to dramatically increase the allowable string length.
