Fill Container Size

Splitter with Width and Height set to 100%

Left Pane
Right Pane

If you place the RadSplitter into a container element in the page you can set its Width and Height properties to 100% and this will resize the splitter to fill the dimensions of the container element. You should set all the panes dimensions in % as well.


The Splitter in the example above is nested into a layer with height set to 500px and width set to 800px. The Splitter's Width and Height properties are set to 100% to fill the entire layer size.
