Symbol constrants

[Tim Wendland]

Is there a way to limit the vertail reszing of a symbol. For example, I''m adding a predefined symbol to a diagram, and I only want the user to be able to adjust the symbols length. what is a good way to achive this?

Hi Tim,

You can do this by overriding the Symbol''s OnBoundsChanged() method and within that you can restrict the symbol''s height/width from being modified.

Please let me know if you have any queries on this.

Thanks,
Meera.

thank you Meera,
in my symbol class i add the following:

Protected Overrides Sub OnBoundsChanged(ByVal e As Syncfusion.Windows.Forms.Diagram.BoundsEventArgs)
Me.Height = e.OldBounds.Height
Me.X = e.OldBounds.X
Me.Y = e.OldBounds.Y
End Sub

and now the user can not change the height of the symbol...

Hi Tim,

My apologies for the delay in getting back to you on this issue. I misunderstood that you got resolved on this. Me.Height refers to the currently selected node''s height hence setting the old bounds value to the currently selected node causes the symbol''s height remains unchanged. If your intension is to prevent the symbol''s height from being changed beyond some value then kindly look at the following sample code snippet.

if(this.Height>150.0F)
{
Me.Height = evtArgs.OldBounds.Height;
Me.X = evtArgs.OldBounds.X;
Me.Y = evtArgs.OldBounds.Y;
}

Please let me know if you have any further questions on this issue. We will be glad to assist.

Thanks,
Meera.
