In WPF i want to create an custom TabItem which contains other controls.
After creating the TabItem, i want to add it to an TabControl.
The content of the TabItem will be created dynamically.
The TabItem only will be vissible after clicking on a button, and will close after entering the neccesary information.
After closing the tab, there will be no blank space in the TabControl.
I tried with a custum control, an user control and a class which inherits from an TabItem. But none of them does what i want.
Which is the best solution in this case?
You want to set the TabItem content to the UserControl not inherit from TabItem. Also you can bind the TabControl.ItemsSource to a collection of UserControls that would make it dynamic like you want I believe.
I solved my problem.
Instead of crating an usercontrol for the tab, i created an usercontrol with the contents of the tab.
In my case, that's a grid.
After that, i use the customcontrol to fill the tabitem.

I am making a template using Usercontrol in WPF(C#).
However, when applying this user control, is it possible to subtract a specific part? For example, removing a button?
To substract specific parts from UserControl, Visibility (Collapse, Hidden) option can be used.
Make sure to add dependency property in UserControl for Visibility to show & hide specific part.
It sounds like you are just trying to hide an existing button, which you should do by setting Visibility to Visibility.Collapsed or Visibility.Hidden. This should be done through a binding to the ViewModel of your user control.
If you need a pure XAML solution: No it is not possible as such. However, the reverse is possible: you can add content to a user control, and that effectively provides the same functionality.
What you could do is make a base user control that doesn't contain the button, and instead has a content presenter. A second user control could wrap the base user control and define a button as its content. Then when you don't want to use the user control with the button you can simply create an instance of the base user control.
For an error validation mechanism, I've to be able to "navigate" in my application to one specific pane.
Currently I've one "SelectedNode" and tries to focus the control that is bound to this property(basically, I've an AttachedProperty to set the IsFocus, based on the name).
My issue is that sometimes this page contains tabs. And it appears that the control cannot be focused if it's hidden(not in the active tab).
Is there a way from an UserControl to go up in its visual tree to "activate" all his parent?
I cannot just bind the "SelectedIndex" of my tabcontrol in the viewModel, for a lot of reasons:
The UserControl that has the tab has one sub user control for each tab, so the usercontrol doesn't know what is in which usercontrol
Putting such things in the ViewModel is wrong, the ViewModel should not have to know that it's displayed in tabs or all in the same pane
Thanks!
I am building an application which has an ItemsControl, and my DataTemplate for this contains a ContentPresenter. I am binding this ContentPresenter to a UserControl property of my ViewModel. I would like to be able to allow the user to click a button on the UserControl which then shows that UserControl in a new popup window, and then when closed, it reverts back to being in the ItemsControl.
I can get this to show the UserControl in the popup window no problems, but have no idea how to revert it back to being in the ItemsControl.
Any suggestions for this approach would be greatly appreciated.
thanks
Put simply you should not keep a UserControl (a UI element) inside your "ViewModel". Your ViewModels should hold the State of your UI and not the UI itself. Define two different UserControls for the two parts you want it in but this time Bind them to the same ViewModel properties.
I am just trying out extending TabControl and TabItem for fun; including providing custom styles. I am creating the ExTabControl programatically, and adding several ExTabItem(myDataObject) to the tabcontrol. myDataObject has several properties, like "Title" and "Editor." Editor is of type UIElement.
What I am struggling with is how do I bind the Editor property to be the tab panel's content?
Bind the tab item's content property to a control or another property.
I have a ItemsControl in ScrollViewer and I set ItemsPanel of my ItemsControl to Horizontal StackPanel and i bound it to ObservableCollection of userControls.Now I wanna when user click on icons of open UserControls in my ItemsControl,automatically scrollviwer's offset change to show icon clicked UserControl.( I have a Icon for my each usercontrols)
And also when user open new UserControl ,I wanna my ItemsControl automatically show it ( now when I open a new usercontrol i should scroll my ItemControl to reach it),
