Well, the easy way would be to read the documentation at the site[^]. Please remove your other question on this; you only need to ask it once.

How do I bind a set of radio buttons to a tab control, so when button 0 is clicked, tab 0 is active, 1 is clicked, tab 1 is active, etc?
Thanks

In beginners tongue, You might need to create a new variable that will act as the connector, so that if the value of the radio button is changed, the value of the variable changes and so the corresponding tab is activated.

Personally I'd wire it up via the VM, I presume you want this done via XAML!

They don't really have the concept of "the selected radio button index" in WPF. Kind of lame. You either have to do the mapping by hand (winforms style) or pass in the hard-coded index via a command parameter.
If you are trying to write "professional & re-usable" code, I'd suggest going the route that I did. Create a "RadioButtonGroup" control thats derived from ItemsControl. Your ItemsSource would be an array of strings (or whatever) and your ItemTemplate would simply be a RadioButton that sets up all the bindings for you. Then you would have bindable SelectedRadioButton and/or SelectedRadioButtonIndex properties, so on and so forth.
Sounds like a bit of work (its not really), but I'm assuming you are building a generic re-usable library that you'll toss this in and use on future projects  .

In XAML you could do this by binding the tabItems IsSelected to the IsChecked from the radiobutton. See the example below (for the sake of this example I removed some attributes like Height and Margin)
<Grid>
<TabControl Name="tabControl1" >
<TabItem Header="tabItem1" Name="tabItem1" IsSelected="{Binding ElementName=radioButton1, Path=IsChecked, Mode=TwoWay}">
<Grid />
</TabItem>
<TabItem Header="tabItem2" Name="tabItem2" IsSelected="{Binding ElementName=radioButton2, Path=IsChecked, Mode=TwoWay}">
<Grid />
</TabItem>
</TabControl>
<RadioButton Content="1" Name="radioButton1" IsChecked="True"/>
<RadioButton Content="2" Name="radioButton2" />
</Grid>
|

You can always create a IValueConverter. Bind to the TabControl
SelectedIndex . On each RadioButton, use the ConverterParameter to pass the value that should set the RadioButton to IsChecked. The IValueConverter class is pretty straight forward.

Is it possible to NOT have the PropertyGrid sort the properties?

That's a windows forms control. In any case, I've since decided not to use the propertygrid.

I have a WPF propertyGrid, in which I need to bind the collection of strings to a paramter that should display a combo box.
If I use a property of enum type, then by default control is displaying as Combo box. However I have collection of strings those can't be formed into an enum type (as few strings starts with numbers and some special characters).
List<string> timesList = new List<string>();timesList.Add("MidNight");timesList.Add("3:00 AM");timesList.Add("6:00 AM");timesList.Add("9:00 AM");timesList.Add("NOON");timesList.Add("3:00 PM");timesList.Add("6:00 PM");timesList.Add("9:00 PM");timesList.Add("NightComplete");Wanted to bind the above created list of strings to PropertyGrid, so that it displays the above in the combo box. So what would be the best way to achieve the requirement. Please share the way.

I have a custom control where some action calls a method that calls InvalidateMeasure to update the look of the control. Seems like intermittently, the MeasureOverride doesn't get called.
I am sure the InvalidateMeasure is getting called and have put traces in both methods.
Any ideas on how to make sure MeasureOverride is called? Seems like it might be a .net bug???
EDIT: I actually have code that looks like this in the entry point:
InvalidateMeasure();
UpdateLayout();
So I think the UpdateLayout() is supposed to force that to happen "now".
|
|
|
|
|
It really depends what you're expecting to trigger it. If you've called RenderTransform, for instance, the update doesn't happen becase RenderTransform occurs at the end of the render pass.
|
|
|
|

The control is a custom list control that has in-place edit. It's supposed to be triggered by the standard mouse click / pause. When the mouse click / pause happens, it calls the adorner's "show edit box" method. That method sets the visibility of the edit box and of the adorner and calls InvalidateMeasure() and UpdateLayout().
99% of the time, MeasureOverride() and ArrangeOverride() are called as expected and the edit box is properly shown.
Occasioanlly, the control gets into a state where the click / pause DOES call the adorner's "show edit box" method, but MeasureOverride() and ArrangeOverride() never get called.
Thats the problem that I'm trying to solve, because once the control gets into this state, the edit box never shows because its MO() and AO() that lay everything out.
|
|
|
|
|
Are you sure that MeasureOverride isn't being called? As an experiment, try putting InvalidateVisual just before you leave MeasureOverride.
|
|
|
|
|
When the user clicks the mouse on the column, it calls a public UpdateVisibility() method. That is getting called all the time. That method sets some visibility flags on the internal adorner & textbox, etc. Then it calls InvalidateMeasure() and UpdateLayout(). MeasureOverride() and ArrangeOverride() do the layout work. I have trace msgs in all 3 functions. UpdateVisibility() gets called all the time correctly, but occasionally, the control gets into a state where MO and AO are not called.

Definitely sounds like a bug in the framework I'm afraid then.
|
|
|
|

*sigh*... oh well... gotta open up a ticket with MS then I suppose  . My experience with MS if its a bug that only affects you is "you're SOL. Do it some other way."  .

|

|

Hmm... well, this is weird... dunno what inspired me to try this, but I added an AdornerDecorator to my ListViewItem template as the top level item in the template and now I can't seem to reproduce this issue anymore.

[UPDATE]
Added "ScrollViewer.HorizontalScrollBarVisibility="Disabled" and it works now.
[UPDATE]
I am working on a Contacts List[^]
when I resize the window, they don't wrap. See this.[^]
here's my XAML:
<ListBox x:Name="Contacts"
ScrollViewer.VerticalScrollBarVisibility="Auto"

SelectedItem="{Binding SelectedContact}">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel IsItemsHost="True"
Orientation="Horizontal"
FlowDirection="LeftToRight"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Border CornerRadius="3"

</Grid>
</Border>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Hhow do I make the wrap?

I have a set of data that can be defined by the user, this will consist of item types i provide to them, for example (Text/Date/Decimal/Address/Lookup/Group). A group allows them to put related data together, groups can be nested as deep as the user requires. Think Composite pattern. As every user is able to create their own structure how it is best displayed will also vary from user to user.
I would like to be able to provide a mechanism that allows the user to select how they want their data displayed. To do this i have created a ResourceDictionary for each way of displaying the data but i've struggled to find a good way to implement switching between display methods. I have looked into switching the ResourceDictionary in code but could not find a good way to implement this. I've also thought about implementing a DataTemplateSelector and again struggled to get this working.
I tried creating empty interfaces (IShowAsTree, IShowAsTabs, IShowAsGroupBoxes), implementing them all in my view that holds the data, and casting when i return the property they are bound to.
public interface IBaseView{}
public interface IShowAsTree:IBaseView{}
public interface IShowAsTabs:IBaseView{}
public interface IShowAsGroupBoxes:IBaseView{}
public class DataCollection:BaseVM, IShowAsTree, IShowAsTabs, IShowAsGroupBoxes
{
}
public class ExtenededDataView:BaseVM
{
public String[] ViewAsOptions{get{return new[] {"Tree","Tabs","GroupBoxes"}}
private String _viewAs;
public String ViewAs
{
get {return _viewAs;}
set
{
_viewAs = value;
OnPropertyChanged(()=>View);
}
}
private DataCollection _view;
public IBaseView View
{
get
{
switch(ViewAs)
{
case "Tree":
return _view as IShowTabs;
break;
}
}
}
}
This failed, should have known but DataTemplating appears to only work on classes not interfaces. This is when i decided on quite a hack for a solution, replace the interfaces with classes, and put a property in the parent class that holds the DataCollection. This works but feels wrong, so if any one can advice me of a better solution, or an area to research more it would be appreciated. Thanks to anyone who read this far, code was typed in so may well contain the odd error, but hopefully its enough to describe the problem.
Working Hack:
public class SwitchMyUI
{
public DataCollection Details { get; set; }
public SwitchMyUI(DataCollection details)
{
Details = details;
}
public SwitchMyUI(SwitchMyUI copyFrom)
{
Details = copyFrom.Details;
}
}
public class ShowTabs : SwitchMyUI
{
public ShowTabs(SwitchMyUI copyFrom) : base(copyFrom)
{
}
}
public class ShowTree : SwitchMyUI
{
public ShowTree(SwitchMyUI copyFrom) : base(copyFrom)
{
}
}

Im a little confused as to what exactly you are trying to do. Do you want to creat a custom "user control" of sorts?
