Hi,

Is it possibel to get an event for expand/collapse of docking control. I want to save the state when this happens.

Regards,
Bob

Hello Bob Duffy,

The server-side event that is raised is Command. You can handle it the following way:

1. Attach a handler in code-behind:

dock1.Command += new DockCommandEventHandler(dock_Command);

OR

attach a handler in ASPX:

<telerik:raddock id="dock1" runat="server" defaultcommands="ExpandCollapse" oncommand="dock_Command">
</telerik:raddock>

2. Handle the Command

void dock_Command(object sender, DockCommandEventArgs e)
{
         if(e.Command.Name == "ExpandCollapse")
         {    
              //your logic here
         }

}

Make sure you set CommandsAutoPostback="true" so that upon clicking Collapse/Expand a postback wll be initiated.

You can also handle the command client-side by specifying the OnClientCommand property of RadDock. Let me know if you need further assistance with this.

I have a similiar problem here. I get a visible post (the page flickers) but the event method newDock_Command() is never executed...

Telerik.Web.UI.RadDock newDock = new Telerik.Web.UI.RadDock();

newDock.ID = "contactDock_" + currentContact.Account;

newDock.Title = "Kalender - " + currentContact.Cn;

newDock.AutoPostBack = true;

newDock.Command += new Telerik.Web.UI.DockCommandEventHandler(newDock_Command);

newDock.CommandsAutoPostBack = true;

Telerik.Web.UI.DockCloseCommand closeCommand = new Telerik.Web.UI.DockCloseCommand();

closeCommand.AutoPostBack = true;

newDock.Commands.Add(closeCommand);

newDock.Commands.Add(new Telerik.Web.UI.DockExpandCollapseCommand());

protected void newDock_Command(object sender, Telerik.Web.UI.DockCommandEventArgs e)

{

if (e.Command.Name.ToUpper() == "CLOSE")

{

this.uxRadDockZone.Controls.Remove((Control)sender);

}

}
