Find Special Characters in Textbox

[Talha]

Hi.,

I have a multiline Textbox., Users are going to enter the Text value. If users are enter any Special Character, i need to notify in label..

if User enter as PowerApps& then we need to inform you have enter a special char &.

So i need to avoid this list of letters &_,.';:/""!@$%^+=\|<>{}

this is possible in Textbox..

Thanks

Hi,

What you're trying to do should be possible to achieve. I've spent too long trying to get this going, but I'm sure it will work if you spend some time trying to work out the regular expression.

See https://powerapps.microsoft.com/en-us/tutorials/function-ismatch/

I'd reccomend doing something like:

If(
IsMatch(TextInput1.Text, "Your regular expression"),
"The field cannot contain the following characters: &_,.';:/""!@$%^+=\|<>{}"
)
