You can integrate other controls inside the Splitter panels. Validation errors may occur in the ASPX page on adding other controls in SplitPane
On adding Syncfusion controls inside the SplitPane the ASPX page complains saying “Element Unknown” and does not show up any compilation error. To get rid of this validation error in the ASPX page on adding other Syncfusion controls to SplitPane, you have to add the controls under the PaneContent element. PaneContent is defined inside the SplitPane element, to support adding other controls to the Splitter window without any warning or error messages.
