I am interested in <telerik:RadMaskedNumericInput maskedInput:MaskedInputExtensions.Maximum="1000" />
But in their examples they are setting a property like MaskedInputExtensions.Maximum directly in the XAML. So if I want to use it I have to go to go to all my XAML files and set it there.
But since I have created my own control so I have both a CS source code for it and also my own XAML for the style of my control.
Is there a way I can set it in either of those places to make it more reusable?
The best way to do it is using styles.
Check this out.

It means that you have a pre-defined style for every element of a certain type, so if you want to change the same property for every element of that kind you just change this specific style.
If this is not what you want you can also create a property called "Maximum" for example and bind it to your controls manually. Once you change this property it will reflect on your controls.
Hope it helps!!

I seek to change the default setting of a .NET Windows Forms control's property, without creating a custom control inheriting from it.
What I want is, for example, to add a TextBox on my Form that already has the TextAlign property set to HorizontalAlignment.Right instead of HorizontalAlignment.Left. Even if only solution-wide, if achievable, I would love to know. This would save a lot of time for when one is working with a LOT of controls and needs to set their properties to specific, non-default, values.
Creating a custom control is just too overkill for this, and would clutter my solution with unnecessary things. I have also considered running a regex on the designer files solution-wide (to add the non-default values to such controls), but writing regex like that can (also) be time consuming/problematic.
Any ideas?
There is a way to do that. But you need to set the binding initially. Later on you can set in one go to all the controls of your choice. This might be not your exact answer but this is how we define styles like as in WPF
(1) Click the Application Property Bindings
(2) Define Binding
(3)Now for textbox you can set the initial default
(4) Now You can set the property binding of every textbox intially or you can code which will set the application settings at starup or on form load.
This will you help to change the default propety at once later on
I am new to Silverlight, but I couldn't find anything about this when I googled it.
I have a button that I am trying to set the style programatically. I have the style defined in a XAML file and I want to pull the style into C# so I can dynamically create a button and assign it this style. So far, this is what I am trying:
button.Style = (Style)Resources["CloseButtonStyle"];
However, it just makes the button have no style. Is there an easy way to do this? I feel like this should be obvious, but I can't get it to work.
You are assuming that your Resources property on the current object is the one that contains the defined style. However, I assume, given the symptoms of your issue, that CloseButtonStyle is actually defined further up the control hierarchy.
Instead, you need to traverse your control hierarchy until you find the resource (or if you know the object that defines it, just refer directly to that object). Unfortunately, Silverlight doesn't include FindResource call like WPF, but it's not too difficult to implement your own.
I can call button1.Style = (Style)Resources["NonExistentKey"]; and it makes my button have no style at all as well, point being that the resource is probably not being found, you won't get an exception.
You directly access the Resources property, but is the style really in the immediate resource dictionary of your Window/UserControl/whatever-you-have?
Can I add some kind of custom attributes in XAML ?
Perhaps you mean Attached properties (scroll down for info on how to create a custom one)? For examle "DockPanel.Dock" is an Attached property.
Or maybe Markup extensions? (though that is something a little bit different)
You can also place Attributes on custom controls and read them in code behind - just like any other .NET class, but that is not possible to do from XAML (since those are set per-type/method/..., not per-instance).
You can, using Attatched Properties. This lets you add your own and data to the xaml on any control you choose.
I'm new to wpf and now I have a problem. I have a model class say Customer and I've created a DataTemplate with TargetType property set to Customer. It works good. But I actually want two different templates like one for just displaying the record and another for in-place editing. Is it possible to specify two different templates for same datatype based on some creteria?
And I want to switch this template based on some property on ViewModel like when IsEditmode is True.
Or am I doing it wrong? Should I use styles instead?
Your approach seems to be perfectly fine.
You can create a DataTemplateSelector which will allow you to choose a data template based on arbitrary criteria from code behind.
I often use these to decide which template to use based on a enum-type property.
There are two easy ways I can think of, ofcourse there are other ways based on the complexity and architecture you want to follow.
Define DataTemplate with 'Key' and specifically call that either using StaticResource/DynamicResource Binding.
You can have a DataTrigger inside the datatemplate which makes some parts of the template visible/collapsed based on your 'EditMode' property
Trying to implement what I thought was a simple concept. I have a user control (view) bound to a view model which provides a list of data. I have added toggle buttons to the usercontrol and would like to allow the user to use these toggle buttons to switch out which template is used to show the data. All of the templates used for the data work, and they are very different from one another so it's not just simple changes to a single template. I'd like to get this as much in XAML as possible.
Here's what I have now:
Where the data appears I have <UserControl Template="{StaticResource ListSwitchingControlTemplate}" />
In that control template I have all "sub templates" - really it's just all 3 representations with their visibility set to Collapsed. Then I use a data trigger on that control template to show the currently selected view. This works, but I noticed that all 3 representations get bound - they each act like they are active (and they are I guess).
I'd rather be able to truly switch the template at run time. I tried converting the containing user control to use a ContentTemplate for itself, but that just messes up all of the binding I have elsewhere. If only UserControls could use DataTriggers I'd be ok.
Any suggestions on how to cleanly go about getting this behavior. I have an idea that I'm just missing something simple.
Thanks,
Dave
you could do it via code?

One way to do this would be to use a DataTemplateSelector.
Basically, you create a class that inherits from DataTemplateSelector and override its SelectTemplate virtual function. The return value from the function is the DataTemplate you want to use and in that function you have access to the object and its properties, which you can use to decide which template to select.
There is an example on MSDN here:
