Hello,
I use a lot of grids in my application, work fine, but in chrome are very slow, in mozilla, ie and safari work fine, but my users only use chrome. I think the problem is a javascript issue because the chrome consumes 50% of cpu or more when is loading the page.
thank you

Hi,
Please try to use fixed height/width for the Grid. That will speed up the Grid.
Thanks!

Hi,
We are not aware of such issues. You can try to compare our sample page in different browsers and you will not see such problem with Chrome. If the problem continues, please try to isolate the problem into a test project and send the test project to us. We will be happy to look further.
Thanks!

Hello, In this link you can download a test project, run Productos_grid.aspx there are a grid and a button, all works fine until click the button, button just do a postback. If you compare time to reload the page after click button is slower in chrome. After page is reloaded is not possible to use the grid scrollbar. In IE, Fierefox, Safari works fine. http://programe.com.mx/webapplication1.zipThank you

Hi,
It appears that you uploaded the wrong file. There is no Productos_grid.aspx in the sample project.
Thanks!

Hello,
No, there is the Productos_grid.aspx file. If you unzip the project, you can find the file in
WebApplication1 -> WebApplication1 -> Productos_grid.aspx
thank you.

Hi,
I am sorry it's our mistake that we mixed it up with a different test project. You have to remove all the external dependencies from your project, including your reference to other third party libraries as well as your database since we can not connect to it from here. You also need to be careful not to include any sensitive information in such project because you are posting it publicly online so everyone can access it.
Thanks!

Hello,
I made the change you suggested. Now I use the data base Demo.mdb included in EO demo project.
Thank you.

Hi,
You may want to check if you have any third party plug-ins with your Chrome or try a clean Chrome installation on another machine. We tested your application and we do not notice any slowness in Google Chrome.
Thanks

Hello,
I've tested the application at least in 10 computers with different capabilities and configurations, Windows 7, 8, XP 32 and 64 bits and grid's behaviour is the same, after a postback, like clic the button. What Chrome version are you using??

Hi, We use Chrome 28.0.1500.52. Our steps are: 1. Run the page. Open the page on Chrome; 2. Click "button" to post back the page. The page reloads. Sometimes Chrome is so efficient that even if the page has been reloaded, the page does not visibly go back and then display again. In another word, visually it looks like nothing happens. However if we set a break point in Page_Load, the break point will be hit; 3. The reloaded page function fines; One thing that I DO recommend you to try is, since you are using CallbackPanel control, you should set your request/responding encoding to utf-8 in your web.config:
Code: HTML/ASPX
<globalization requestEncoding="utf-8" responseEncoding="utf-8"/>
Let me know if this fixes the problem for you. Thanks!

Hi,
We are not aware that version 28 is a beta. Maybe it's because that we are in different countries and Google rolls out different versions at different times for different locations.
Thanks!
