How do I fill a textbox with text if it is empty? I am using VB.NET.
I assume you meant to add text from the aspx page.
Even when .NET don't suggest this feature in the intellitext, I assume that it will allow you to put any attribute, even custom that you can manipulate data in it. But, it does the work. and the value attribute is sent to the browser, therefore, initiate in the text field.
For TextArea (TextMode="MultiLine"), you can put between the tags.
Text Here will be inside the TextArea
It is like html textarea tag behave.
