• Forgon TreeView doesn't cancel user check

  Hi, I have a tree view which holds directories and the state if the content is installed or not. The user should not change the state of the CheckBox - this is done by code. But if the user clicks quick enough (first double click is the encounter of this behaviour) the checkbox changes its state. This is my code to test that: private void tvDirectories_BeforeCheck(object sender, TreeViewCancelEventArgs e) { e.Cancel = true; } With this code - I cannot set the checkbox with code. But the user can that (after first double click). What's wrong with this code Thanks in advance. Neither TreeView nor TreeNode have a ReadOnly property. Yah, code is a good idea. @LorMee You are r ...Show All

• Leon Mayne How to iterate through Windows Forms list box

  To find the selected items in a mulit-selection list box, I have tried foreach(ListItem item in myListBox.SelectedItems) but "ListItem" is not recognized. How can I identify each of the SelectedItems in order to extract their value Thanks in advance Items of what type are you adding to the list Can you post some code Andrej If you bind a datatable to the listbox, the items in the list are of the DataRowView type. To iterate through them you can use something like: foreach ( DataRowView rowView in listBox1.SelectedItems) { DataRow row = rowView.Row; //Process row... } If you're using typed datasets you can also cast rowView to a typed row... ...Show All

• Christian Frießnegg Control for docked "flyout" (unpinned) panels?

  I'd like to include a pinned/unpinned navigation window in my C# Winforms app that works like the docked windows in the VS05 IDE that are docked on the side with an icon and legend. In the unpinned mode it should open smoothly when you hover over the icon. I'd like to display a treeview in the panel and have the pin/unpin toggle icon as in the IDE. Is there a control that can reproduce this behavior in a Winforms app Edit: I found this: http://xceed.com/Docking_WinForms_Intro.html.  I was hoping to find a free version. Yes, I got the one from SF. I'll look for the patches. I plan to build a prototype with it this week for my client, then bang on it to see if the control is ready for production use. ...Show All

• Eric Brinkerink AutoScroll question

  hi, if i have a form that has the AutoScroll property set to true and i have a control on the form that is located at say (-10, 10) then shouldn't i get a horizontal scroll bar i don't and i am wondering how i can get it aside from implementing scrolling by myself. thanks, scott Sorry, it's confusing to me what you're trying to accomplish and why you would use two panels. Just set the AutoScrollMinSize property to a value larger than the UserControl's size and the scrollbars will automatically appear. If you are using the Paint event to render your "virtual objects", offset the coordinates of those objects by AutoScrollPosition. And write a Scroll event handler that just calls Invalidate() to ...Show All

  Hi How do i populate a listbox in window1 from window2. Have a lisbox named "listbox1" in window1. Cant just write "listbox1.Items.Add()" to populate the listbox from window2 Regards Fredric You have two options: 1. in window1, change Modifiers of ListBox from Private to Public. So you can access listbox like: instance_of_window1.listbox1.acction_you_want 2. ListBox modifiers are Private and in window1 declare some public method - public void ClearListBox . public void ClearListBox() {     this.listBox1.Items.Clear(); } You can access this method like: instance_of_window1.
