I have 4 Panels that should be shown/hidden based on 4 radio buttons being checked.
only a single panel will be shown at a time.
all 4 panels need to be shown in the same position (within the same grid cell)
The problem is, once all 4 panels are put in the same grid cell, the panels are overlapped and
difficult to do changes to any specific panel in design mode.
Is there any way that we can hide the panels in design mode so that i can work on a single panel at a time?
Thanks.
Your best option is to create a UserControl for each panel, and display the UserControl instead of the Panel. You can then edit each UserControl by independently.
There is a pretty straightforward tutorial here - http://www.longhorncorner.com/UploadFile/raj1979/WPFUserControl09012008000033AM/WPFUserControl.aspx.

Hello pplwould like to know if we can do a panel like this in WPF.
Where I sent a list item for the usercontrol, and after that the control showed items that were possible, and if more it shows the next and previous buttons. In windows forms I have. Now wpf in that complicated. I can not show items as monitor size user even knowing how many are being presented, he puts her items and then can not do paging. Can you help me?

You could have a horizontal StackPanel in the grid and scroll the StackPanel with two buttons.
I have a UserControl. In it I have a TableLayoutPanel control with columns and rows. In cell I have basic windows forms controls like textboxes, comboBoxes and checkboxes.
For first two of them if I set their Anchor to Top, Left, Right they are re-sizing when the form is resized so the form looks ok.
Now, I want that when the page is resized the CheckBox to be also in the middle of the cell.
Mention: in each cell I have Panel control in which are placed a label control and one of three mentioned above.
By default a checkBox control is set to align Top-Left. Set it to align none and it will do exactly what you're looking for.
I got Panel 1 and Panel 2 using splitContainer in the Windows form. I want to keep the original size of the Panel 1 . I just want to maximize the size of the Panel 2 from the original starting point when I maximize the form in the interface.
I tried to change the setting in the splitContainer properties dock but i couldn't succeed....
How can I maximize the Panel 2 alone ????
When I checked this link, there is no solution for my problem. http://support.microsoft.com/kb/953934
Set the SplitContainer.FixedPanel property to whichever panel you want to keep fixed, or use simple panels and anchor them properly to your needs.
I'm converting an app from ASP.NET WebForms to WinForms. There is one asp.net page which contains a ListView/Repeater that contains several custom controls, which in turn contain a ListView with other custom controls. Basically the layout looks like a TreeView, but on each node/leaf there are few controls like comboboxes, etc.
When this is in ASP.NET, the page automatically lays itself out, so it is several screens tall - if I add 20 buttons into a Panel, it will grow and the browser will get scrollbars.
I'd like to do the same thing in a WinForms application - so I'll have a user control that will contain a lot of controls in a some variation of Panel (Flow, Table layout), and the controls might have another controls inside them, etc.
The problem is, that when I make winforms app, each control has specific height in the design time. I'd like some user controls to be able to grow with their contents - so they'll add up. In the main Form, there should be a vertical scrollbar, just like in the web browser when the generated page is taller than the screen.
I'd just like to get some general pointers in the right direction. Thanks.
Use Anchor and Dock container properties.
Yes, to expound on Anchor and Dock...try this
-Place a Panel on an empty form, and set its dock property to Top
-place a textbox in the panel, and Dock it to Full...it should fill the whole top panel
-Place a splitter on the form, and if not already docked correctly, set its dock to top
-place another panel below the splitter, and set its Dock to Fill
-place another textbox inside the lower panel and fill it as as well
Now you have a form with two resiable textboxes and will resize when the form does.
*you may have to set the textbox MultiLine property to true but not sure.
Hope this helps.
Anchor the controls to the parent. Anchoring all four sides will cause it to stretch.
If the Anchoring and Docking answers don't work for you, there is another option. It's not pretty, but you can access a control's properties and change them dynamically during runtime. You'd do something like: if(listBox.Items.Count > [yourVal]) listBox.height = [yourFormula] or something.
It's been a while since I've done a Win Form (and I don't have my IDE fired up at the moment) but I'm pretty sure there's even a ScrollPanel or other scrolling control that you can set on your form.
That said, when you're working with WinForms, the less scrolling you can make your users do, the better.
I have a Silverlight form that contains a Stack Panel (orientation = vertical) with 10 rows. Each row contains a TextBlock and Textbox control except the last row has a TextBlock and Drowdown.. At the bottom of the control are two buttons. Previous & Continue.
There are 10 items in the Dropdown. When I select a value from the Dropdown, only two of the ten items are showing up. I believe that the remaining items aren't displying because there's some sort of clipping effect going on. Fair enough.
Does Silverlight allow the dropdown control to display upwards (instead of the default down direction)? Will I have to override some rendering capabiliities before the dropdown is rendered to the control or is there a property that allows me to accomplish this functionality?
The Silverlight ComboBox auto aligns the dropdown popup to always be visible whenever possible.
all Popup based controls (ComboBox, AutoCompleteBox, DatePicker and TimePicker) all have this feature enabled.
So if there's not enough screen real-estate below the ComboBox to show the dropdown popup, it'll show up above the control.
The combobox nesting in the visual tree should not affect the dropdown popup auto alignment. The internal Popup control (inside the ComboBox) ignores the Visual Tree and is nested "above" the visual tree.
If you have specific issues, please share minimal and relevant XAML. Since Keith is on this thread, I think it's safe to say he'll log a bug if needed.
