Hi,

I saw this post: http://www.syncfusion.com/support/kb/tools/Default.aspx?ToDo=view&questId=9

But unfortunately I can not attach to this event, as loading from the persisted state ends up calling this in an infinite loop. Is there any other event I can attach to, or can you post a sample showing what the code should look like to acheive loading a persisted state with no user input??

Thanks,

Henry

Hi Henry,

Thank you for your interest in Syncfusion Products.

The NewDockStateEndLoad event occurs immediately after a new dock state has been loaded. Whenever an application with one or more docked controls is loaded this event will be triggered more than once and this causes calling infinite loop when loading dock state. To avoid this we need to use the flag variable that allows the docking manager to load the docking state only once.

Kindly refer to the code snippet that illustrates this:


bool flag = false;
private void dockingManager1_NewDockStateEndLoad(object sender, EventArgs e)
{

if (flag == false)
{
flag = true;
this.dockingManager1.LoadDockState();
}
}

Please let me know if any concerns.

Regards,
Fathima

Unfortunately m_dockingManager_NewDockStateEndLoad never seems to get called for me... I have definitely attached the event, and I load several depersisted controls into the dockmanager when the form loads, but it still never fires.

Hi Henry,

Can you try the Form's Shown event?


this.Shown += new EventHandler(Form1_Shown);
void Form1_Shown(object sender, EventArgs e)
{
// load the state here.
}


Best Regards,
Mano
