以编程方式更改 xaml 的内容以更改控件的属性

Question

Is it's possible to change xaml programmatically through c#?

I'm trying to do is hide or replace a specific element, using a if statement within my class file.

The code I'm trying to manipulate is below, to be more specific I want to know how to replace Spin="True" with Spin="False" . I'm not sure how it should be done and believe that I need to edit XAML at run-time via code somehow.

<fa:ImageAwesome Icon="Refresh" Spin="True" Height="48" Width="48" Margin="0,350,0,0" />

So at the current state spin is equal to true so therefore the icon within the grid would spin, but I would like to set spin is equal to false during some form of if statement or simply within 5 seconds of the current form being active.

Answer 1

If i understand you correctly you want to control your Spin property programmatically.

You should use the binding option in WPF , Please look into it more thoroughly since it is the basic principle of WPF and Xaml.

Here is an example of what i think you wanted to do :

Xaml part :

<fa:ImageAwesome Icon="Refresh" 
      Spin="{Binding SpinProperty}" 
      Height="48" Width="48" Margin="0,350,0,0" />

ViewModel (in case using MVVM ) :

private bool m_spinProp;
public MainVM()
{
    m_spinProp = true;
}
public bool SpinProperty
{
    get { return m_spinProp; }
    set { SetProperty(ref m_spinProp, value); }
}

Answer 2

Did you try using the name of the control like?

 <fa:ImageAwesome **x:Name="imgSpine"** Icon="Refresh" Spin="True" Height="48" Width="48" Margin="0,350,0,0" />

and just you can check the property of the control.
