Greetings,
I am trying to implement the RadDock functionality in example similar to the "MyPortal" Demo . The language used is C#. I follow the same way as shown in the demo except for the part that instead of populating the usercontrols in the dropdown and clicking the 'Add Dock' button to add the dock to the dockzone , I use seperate buttons and on clicking each button it loads respective user control to RadDock control and displays it. Each control has a Radgrid inside that displays different data.
While opening/closing the raddocks after a point it throws an error such as 'Failed to load viewstate' error . Is there a way to rectify it ?? Since there are controls such as dropdown, radgird which also initiates a postback , I cant set the EnableViewState=false for each page as well.
Also , in the demo Session is used to save/load the raddockstates . How to save and reload these states using database. Can you provide me with an example ? I did search on other forum posts regarding the raddock state persistance , where I see that the states are being only updated or loaded but not inserted so I am not sure how to insert , update and select the rad dock states from the database without having the above mentioned error. Kindly help me asap as its very urgent.
Below attached image shows how my page look like and the c# code is pasted as well.
private List<DockState> CurrentDockStates
{
get
{
List<DockState> _currentDockStates = (List<DockState>)Session["CurrentDockStatesDynamicDocks"];
if (Object.Equals(_currentDockStates, null))
{
_currentDockStates = new List<DockState>();
Session["CurrentDockStatesDynamicDocks"] = _currentDockStates;
}
return _currentDockStates;
}
set
{
Session["CurrentDockStatesDynamicDocks"] = value;
}
}

//We will just add the RadDock control to the RadDockLayout.
// You could use any other control for that purpose, just ensure
// that it is inside the RadDockLayout control.
