Persist Tool Part Values

Asked By: Clem Smith Date: Jul 30, 2010 Category: Sharepoint Views: 2044

Is there any way to have a tool part persist it's values from session to session?
I have tried overriding the SyncChanges method to no avail.
public override void SyncChanges()
{
this.EnsureChildControls();
SLIVersionHistoryView webPartToEdit = (SLIVersionHistoryView)this.WebPartToEdit;
if (webPartToEdit != null)
{
Comment.Text = wp1.HostString;
ddl.SelectedIndex = ddl.Items.IndexOf(ddl.Items.FindByValue(webPartToEdit.HostString));
}
}

This does not work.
Any ideas on the correct means to accomplish this?

Your code is not clear, what is this wp1 object? SyncChanged is used to load the property values from the web part to the tool part, it is called when you open the toolpane the first time, if you need to postback while inside the toolpane, say reload some ddl as a response to another ddl you should rely on viewstate as you would in any ASP.NET app.
