Re: Gantt too slow
Here is an example of the issue.
Try to move the gantt with the right mouse button and see how slow it works.
Thanks in advance.
I've a message that say that the file is too big. My file size is about 1,17 MB.
Where I can send the example of the issue?

Hello Pujol1986,
If you upload the Winforms example, I recomend remove bin and obj folders and try attached again the example here. But, if you don't upload a Winforms example or you don't want remove bin and obj folder, you can upload your files in Steema upload page
Thanks,

Re: Gantt too slow
Hello,
Thanks for the file but I'm afraid the Form.Designer.vb is missing. Would you be so kind to attach it as well? Alternatively you could attach the full project folder excluding bin and obj folders.
Thanks in advance.

Re: Gantt too slow
Hello,
Thanks for the example project. Adding line below improves its performance. Does it behave as expected now?

gracias por la ayuda.
Ahora funciona el doble de rápido, pero continua funcionando lento.
There is something more that I can do to make it run faster?
Thanks in advance.
Re: Gantt too slow
Hello Pujol1986,
You have a way to increase performance of your project, is use TeeChartDirect2D that allow you draw fast Charts with a lot of values. But, it is only available to version 4, for a series of requirements that you need to use this assemble; because these are not compatibles in oldest versions of TeeChart.Net as explain in the WhitePaper_Direct2D.pdf. For this, I recommend that test the TeeChartDirect2D that you found in the last version 4 eval version, try to implement your application using it and check if your performance increase. On the other hand, you need know that version 4 of TeeChartFor.Net is more optimized and increase the performance of the projects made in oldest versions.
