Question

I have a xaml defined like so :

<Grid>
   <Rectangle Grid.Column="0" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="1" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="2" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="3" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="4" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="5" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="6" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="7" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="8" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="9" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="10" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
   <Rectangle Grid.Column="11" Height="{Binding ElementName=CanvaContainer, Path=ActualHeight}" MouseEnter="Rectangle_MouseEnter"/>
</Grid>

What I don't find is a way to access the grid column number I,ve tried to cast the rectangle but I don't find the apropriate property of it.

Was it helpful?

Solution

If you have Rectangle object you can get it using GetValue() method. Say rect is object name then you can get it like this:

int column = (int)rect.GetValue(Grid.ColumnProperty);

Grid.Column is attached property and not normal Dependency Property of Rectangle. Hence you have to pass Grid.ColumnProperty in there.

OTHER TIPS

Grid.Column is an attached property and hence defines the static getter and setter methods Grid.GetColumn and Grid.SetColumn. Please pay special attention to the Attached Properties in Code section of the linked MSDN article.

The usual way to get the value of the Grid.Column property in code is to call the static getter method:

int column = Grid.GetColumn(rect);
