QuestionUse dependency properties with a WPF custom control Pin
bytesport28-Mar-18 0:18
memberbytesport28-Mar-18 0:18 
Hi, maybe everybody can help me with Dependency Properties and a custom Control, this costumer Control contains a grid, the grid shall be created progammatically- new columns with Buttons and external controls.
I have a dependency properties in this custom Control, but when i call the custom Control then the grid doesn't change.

It seems I have no accessto the grid? Because nothing will created in the grid, no column, no button. What do I wrong?

What I have tried:

my dependency property :

public static DependencyProperty Symbol1Name =
          DependencyProperty.Register("Sym1Name", typeof(string), typeof(UserControl1), new FrameworkPropertyMetadata("test", OnSymbol1PropertyChanged))



public string Sym1Name
       {
           get { return (string)this.GetValue(UserControl1.Symbol1Name); }
           set { this.SetValue(UserControl1.Symbol1Name, value); }
       }

The onChange Function

private static void OnSymbol1PropertyChanged(DependencyObject dependencyObject, DependencyPropertyChangedEventArgs e)
       {
           UserControl1 ak = dependencyObject as UserControl1;
           ak.OnPropertyChanged("Symbol1Name");
           ak.OnSymbol1PropertyChanged(e);

}

The function to Change works in normal WPF App:

private void OnSymbol1PropertyChanged(DependencyPropertyChangedEventArgs e)
        {
            try
            {
                

                
                change(Sym1Name, 0);
                

            }
            catch (System.Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }


The XAML:
<Grid x:Name="Grid1" Grid.Column="1" Background="Gray" Margin="5,0,0,0" >

               <Grid.RowDefinitions>
                   <RowDefinition Height="Auto"  />

               </Grid.RowDefinitions>

           </Grid>
