hi, i'm trying to load a panel dynamically. after i create a new object in my Diagrams collection, i just want to empty the panel and reload. am i even close to correct here?:
private void LoadWorkflowsToPanelBar()
{
var workflowsPanel = rpbTools.ChildrenOfType<RadPanelBarItem>().ElementAt(0);
workflowsPanel.Items.Clear();
foreach (var sssWorkflowDiagram in Diagrams) // Diagrams is a collection i keep elsewhere
{
RadPanelBarItem panelBarItem = new RadPanelBarItem();
StackPanel stackPanel = new StackPanel();
stackPanel.Orientation = Orientation.Horizontal;
Image image = CreateImage("../Images/workflow.png", "../Images/workflow.png", sssWorkflowDiagram.Name);
TextBlock textBlock = new TextBlock();
textBlock.Text = sssWorkflowDiagram.Name;
stackPanel.Children.Add(image);
stackPanel.Children.Add(textBlock);
panelBarItem.Tag = sssWorkflowDiagram.Id;
panelBarItem.Header = stackPanel;
workflowsPanel.Items.Add(panelBarItem); // error is here
}
}
this works fine the first time through, but the second time it is called, it does not load correctly. when i debug this code, the following exception is thrown when the loop gets around to my new diagram:
{System.ArgumentException: Value does not fall within the expected range.
