RadTextBox Very Large Amount of Text Hangs Browser

[Josh]

While using a RadTextBox, if a user has a very large amount to text, the text box hags the browser and maxes out the processor.

Hi Josh,

Generally it is not recommended to use the RadTextBox with such amounts of text as it was not designed for that purpose. I can suggest you to use the RadEditor as an alternative which was built to handle such scenarios.
