Hi,
I´d like to animate Shape properties like FillColor, LineColor, ... . Therefore I do
[code]
Shape.SetPropertyValue("FillColor", Color.Red)
[/code]
inside my own thread. This does the trick but I run into problems when I now have e.g. MouseMove´s over the Diagram. These events block the updates of my new FillColor settings. How can I make sure that my new props will be set even when there are user inputs on the diagram?
best regards,
Uli

Hi,
Kindly refer the Diagram Samples/DynamicSymbol sample. The MySymbol.cs class will give you an idea about how the symbol responds to MouseEvents.
Please let me know if you have any queries on this issue. We will be glad to assist.
Thanks and Regards,
Meera.

Hi Meera,
I think I did not describe my problem in a sufficient manner.
I integrate a live value interface in all Diagram´s which gets the values from a process data server e.g. all 500ms. Every value change I´d like to animate a particular property of a Symbol which is defined from the user at draw time. Therefore I build some dialogs where the user can input the information for the animation like:
decimal lowLimit = 0;
decimal highLimit= 100;
//FillStyle
Color fillColor = Color.Red;
Symbol rectangle = (Rectangle)Diagram.Model.Node;
...
When the diagram now receives a value change callback and the value is in the limits the Rectangle should set his FillColor property to Red or to other user colors. The callback runs in his own thread container.
rectangle.SetPropertyValue("FillColor", newColor);
So far there is no problem with Rectangle.Update even when I get a lot of callbacks.
But I have a problem when I do a lot of MouseMove´s over the Rectangle when the animation is running. This moves are blocking the update of e.g. the new color change. I think this problem has to do with different thread priorities and may is not a problem of your side. Do you have an idea of how I can force the symbol to update his property even when there are heavy MouseMove´s or other gui inputs?
Please let me know, when you need more information.
best regards,
Uli

Helli Uli,
Please try to force the Diagram to refresh itself immediately after the ''SetPropertyValue(...) call, by invoking the diagram.Model.UpdateAllViews() and diagram.Refresh() methods right after the property change.
As thread management is completely local to your application, I am afraid I can''t afford much more help on this issue.
Thanks for your support to Syncfusion.
Regards,
Meera.
