Hi,
I have tested the setup configuration but I cannot replicate the behavior. The only behavior I can replicate is that when you set the "Text" attribute to
{260} and you type in (multiline) the following input:
Code: Select all
123456789012345678901234567890123456789012345678901234567890
123456789012345678901234567890123456789012345678901234567890
123456789012345678901234567890123456789012345678901234567890
123456789012345678901234567890123456789012345678901234567890
123456789012
you can no longer type in any additional character. But please note that even you see only 252 visible characters, the above input includes 260 characters. There are 4 new lines invisible characters (don't know for sure but I assume a \n sequence) which count 8 chars I suppose.
To double check on this just copy and paste the above input in a text editor tool (e.g. Notepad++), select it and you will notice the selection includes 260 chars.
If you want to be able input a large number of characters into your edit box control just set the "Text" attribute to
{0} , this will allow you to enter up to 2147483646 characters.
If there is anything else we can help you with just let us know.
All the best,
Daniel
