How to ******* the CustomTaskPane Control in Outlook

[C# Programming]

Hi,

I am writing an outlook Addin which shows a panel on the explorer window of Outlook.
The Panel shows some details regarding the sender of the Email. My user control "TaskPaneControl" has a panel along with some other controls. My code is as below.


Microsoft.Office.Tools.CustomTaskPane taskPane;
Microsoft.Office.Interop.Outlook.Application applicationObject;
Outlook.Explorer explorer;

private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
explorer = this.Application.ActiveExplorer();

explorer.SelectionChange += new ExplorerEvents_10_SelectionChangeEventHandler(activeExplorer_SelectionChange);
}

void activeExplorer_SelectionChange()
{

if (taskPane == null)
{
taskPane = Globals.ThisAddIn.CustomTaskPanes.Add(
new TaskPaneControl(), "Sender Details", explorer);
taskPane.Visible = true;
taskPane.Width = 245;
return;
}

if (taskPane != null)
{
Microsoft.Office.Interop.Outlook.Selection selection = explorer.Selection;

if (selection.Count == 1 && selection[1] is Microsoft.Office.Interop.Outlook.MailItem)
{
Microsoft.Office.Interop.Outlook.MailItem mailitem = (Microsoft.Office.Interop.Outlook.MailItem)selection[1];

TaskPaneControl ct = new TaskPaneControl();

ct.ShowEmailDetails(mailitem);
}
}
}

The problem here is, on change of Email in the inbox, activeExplorer_SelectionChange method gets executed but the taskpane will not be *******ed.
Please let me know how to ******* the Task pane Contol.

Thanks in advance.
