Hi @Abinayakandan
Can you use below Custom Java code (I have mentioned 3 different ways, you can use anything).
Note: Recommended Method 3
Create one Edit Validate rule, then copy below code and paste.
You can use this edit validate rule into under advance tab of the property.
Note: Error Message your wish; you can change according to your needs.

//--------------------Method:1--------------------//
for (int pos = 0, len = theValue.length(); pos < len; ++pos)
{
char c = theValue.charAt(pos);
int ascii =(int)c;
if ((ascii<0 || ascii>43) && (ascii<45 || ascii>123) && (ascii<125 || ascii>125) && (ascii<127 || ascii>127))
{
theProperty.addMessage("Not Allowed Special Characters ~ , |");
return false;
}
}
return true;
//---------------------Method:2--------------------//
for (int pos = 0, len = theValue.length(); pos < len; ++pos)
{
char c = theValue.charAt(pos);
int ascii =(int)c;
if (ascii==44 ) // This is blocking the Comma , Symbol
{
theProperty.addMessage("Not Allowed Special Characters ~ , |");

return false;
}
}
return true;I hope this will help you.

hi @Bhumireddy, we have one section , in that section we have many text input and text area . instead of giving for each property advance tab , did we have any solution for whole section that special character needs to be restrict?
Hi @Abinayakandan,
We have a validate rule, that is server-side validation. Even with that validation rule, you have to write the logic for all properties.
As per my knowledge, we cannot apply the whole section at once.
But you can reuse the Same Edit Validate rule for all properties those properties are available in that particular section.
Thanks,
Ashok
