Get Exact Size Of Scrolled Panel?
Sep 2, 2009
i have a panel on a form and i have various controls inside the panel which i then shrink and enable the panels scrollbar so i can scroll through the controls. i am trying to get the exact size of the panel (unshrunk).for example the panel is 500 pixels in width and i then shrink the panel down to 300 pixels and enable the scrollbar. when i try to get the size of the panel using code like
panel1.size.width.tostring
it keeps telling me the panel is 300 pixels long ..which yes it is because i shrunk it down but i want to get the full size of the panel which should be 500.

I need my window to be an exact size. Isn't it possible to specify the exact size of the client area (the drawable part) as opposed to the entire form including the menu bars etc?

I am using a textbox which handle the name of the employee and when it get focus i am using a listview with detail view which shows all available employees and user have to select any of them. I am using all this control in a panel, unfortunately listview need more size then panel, and i cannot increase the size of panel. But placing listview inside the panel make its child control and hide the half list view. Is there any way that i can show full list view control under the textbox?

I thought this would be easy but for some reason it's giving me a rough time. I have a windows form with three equal size panels on it. Each panel takes up about 1/3 of the window width, less some inter-panel spacing.
The effect I want is if the user stretches or shrinks the form the panels maintain their relative 1/3 width and spacing, similar to how divs on an html page would size as the browser window is sized.
So I anchored the left panel to left, top and bottom, the center panel to top and bottom, and the right panel to top, bottom and right. This works fine in keeping the left and right panel anchored to their respective sides, and all panels now stretch with a form height change.
So in form resize I adjust the width of each panel to form.width/3. As expected this is close but does not account for the inter-panel margins I want to preserve and the form border width.
I played around with various constants and noting I do gives me the desired effect.I'm sure there is a pretty straight forward solution to this but I can't seem to find it.

I have a form on with I have a label inside a panel, with a button I can open a fontdialog and change the font of the label (inside the panel). The font (name and size) I also display in 2 textboxes. This works as far. But I also want to display in a different label (so not the same as the label inside the panel) which fontstyle is selected (at this point when I select bold, the number 1 is displayed in the label, but I want to the word Bold displayed. Also I found out that when I make the fontsize smaller, the label inside the panel isn't align in the middle of the panel.

During my program I put lines out to a text box on the screen as a form of logs.After each line is added I do a ScrollToCaret() to move to the end of the lines.However, if I'm manually scrolling around the logs/lines (eg: using the scroll bar) I don't want to that.
Is there something I can check so as not it issue the ScrollToCaret() if the user if currently scrolling around in the text box?

A simple form with a combobox called Combo, drawing artifacts when using ComboBox with Custom Draw and the contents of the combobox is scrolled up or down, and with this source code, illustrates the issue:
Public Class Form1
Private Sub Combo_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles Combo.DrawItem
Dim Combo As ComboBox = TryCast(sender, ComboBox)
If Combo Is Nothing Then Exit Sub
If e.Index = -1 Or e.Index >= Combo.Items.Count Then
e.DrawBackground()

I set up an Openfiledialog and put in an initial filename value (the last filename the user opened).However, when the dialog shows up, it is as if the filename has been scrolled off to the left.I only see about the last 10 characters of the name, even though the filename field is big enough to show the whole name.It is also selected, which is ok - it means if the user types a name the value will replace what I've put there, which is reasonable behavior.How do I control this 'scrolling'?I call it scrolling even though there is no scroll bar.If I click in the field and use the left arrow key I can back up to the beginning of the filename - the filename gradually shifts into view about 10 characters at a time, until I reach its beginning, at which time I see the entire filename in the filename field which is how I'd like to have things when the opendialog opens.

I am modifying some code I found here to test to see if a user has scrolled to the end of the control. In this case the control is a Crystal Viewer but I posted here because I think the issue is based on the vertical scrollbar not the Crystal Viewer itself.
The code flags an error at
Me.CRViewer.Controls.OfType
Indicating 'OfType' is not a member of 'System.Windows.Forms.Control.ControlCollection'.
I understand the concept that I can't reference something that it is not but I don't know how to fix it. The original code was for a DataGridView.
The ultimate goal (not finished) is to find out when the user has used the mouse or possibly the scroll bar itself and if it hits the bottom of the page of the viewer, then trigger a new page so it looks like they can just keep using the mouse to scroll.
Public Sub New()
Me.InitializeComponent()
Dim vscroll As VScrollBar = Me.CRViewer.Controls.OfType(Of VScrollBar)

I am writing a GUI application to run on a touchscreen device using VB.NET and WPF--it must be full screen at all times, like a kiosk app; the window must not be able to resize or move in any way. The window contains a ListBox that users can currently scroll through by dragging across the list. The problem I'm seeing is that when the user drags across the list, the whole window moves a bit, exposing the desktop underneath, then springs back into place once the user stops dragging. I have not been able to figure out how to keep the window stationary while still allowing users to drag across the ListBox to view all list items. Here is a somewhat simplified version of my code:

Now all went well about from using the structure correctly. The working of the structure was perfect. How ever i missed Two important issues. The structure needed a fixed size of 10 items (9 in programming terms starting from 0) And also out of the 5 items allowed to be chosen as one of the member types for the structure a limit of 5 items of that particular type.

I would like to add an effect where a panel sweeps out of the way to make room for another panel. This is sort of like a sliding effect, and I think at one point in time this could be seen on Apple's website under their product pages. I came up with some code, but it isn't working.

When a user is editing a given piece of data, they're allowed to add messages/comments. These are stored as child records in a SQL database. Clicking on the Add Message button brings up a panel (pnlMessage) courtesy of the AJAX ModalPopup Extender. This takes some input and, when the "Send Message" button in the panel is clicked (I learned the hard way to NOT make that the 'OkButton' property), the message is stored in the database and an email is sent to the intended recipients. No problem there.
However, I need to be able to allow the user to add new email addresses (so long as they are registered in our database). I have another ModalPopup / panel combo (pnlSearch) that's tied to a button on the previous panel (pnlMessage).
The user is supposed to be able to add an email or click on a search button to populate a list to choose from.
The pop-up panel (pnlSearch) comes up just fine, but clicking the "Lookup" button (which instigates the search and returns a collection of records that the user is supposed to pick from) closes the panel.
Previously, I ran into the problem of having the Button.Click event never firing when I put the Button into the "OkControlID" property (the CancelControlID works fine since I don't want to do anything). Removing the "OkControlID=Button" line allowed it to work perfectly with the Button.Click event firing as expected.
So now I have the Search panel with a button for "OK" and a button for "Search" - but the panel should stay up and visible after the Search.Click does it's thing. Am I missing some property that basically says "don't close the panel when this button is clicked"? Of course, if I bring up the panel again in the same session, the results from the previous effort are there (the search results).

I have a TopBar, A LeftBar, A VScrollBar, A HScrollBar and a Panel inside a SplitContainer Panel.The issue I'm having is that when my SplitContainer Panel is small enough to enable one of the ScrollBars, I will slide the ScrollBar and then when I resize the Split Panel, my Panel1 is staying where I scrolled it too.I'm having troubles thinking of the correct code to fix this.

I'm working on a visual studio 2008 VB.Net project (.net framework 2.0), and am having some trouble with the Panel control using a fixedsingle border. As a small example of the problem, suppose I have one Panel2 contained inside of Panel1. If the Left position of panel2 is set to 0 (meaning it's border is up against the left edge of Panel1), the left border will show as bold, and slightly indented.
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class Form1
Inherits System.Windows.Forms.Form[code].....
What I'd like to see is just a single line, not bold or indented, where the two panels borders are equal.Is there a property or custom paint technique I could use to achieve this behavior?

Of course, the Graphics.MeasureString method is well-known to have padding problems, and so you use Graphics.MeasureCharacterRanges instead, but as you can see here:It's not measuring quite correctly. Is this a problem with MeasureCharacterRanges or is it my code? How can I fix it? [code]

This is for a mapping/plotting program.
t.panel is the main panel and it has too much content to fit in one screen so there are scroll bars. x.panel contains the horizontal scale for the data points in t.panel. I drew the scale using a bitmap and set it as x.panel's background.
Setting x.panel's horizontalscroll.value = t.panel's horizontalscroll.maximum doesn't seem to work. I think this is because x.panel's doesn't have any content that causes it to need scroll bars.
