HtmlLabel Control

You can use it just as an HTML container control, just place the label on a form and feed the Text property with HTML code.
Using AutoSize and AutoSizeHeightOnly client can control how the html content effects the size of the label. Either case scrollbars are never shown and html content outside of client bounds will be cliped MaximumSize and MinimumSize with AutoSize can limit the max/min size of the control.
The control will handle mouse and keyboard events on it to support html text selection, copy-paste and mouse clicks.

Try the Sample Form to play with html label control.

Remarks

Differences between HtmlPanel and HtmlLabel

The major differential to use HtmlPanel or HtmlLabel is size and scrollbars.
If the size of the control depends on the html content the HtmlLabel should be used.
If the size is set by some kind of layout then HtmlPanel is more suitable, also shows scrollbars if the html contents is larger than the control client rectangle.

• HtmlPanel has scrollbars support
• HtmlLabel can be autosized
• HtmlLabel can have transparent background
