Hello NGUYEN VIET THANH,
Thanks for posting in our forum.
I tried reproducing your problem but could not see the issue. What version of the product do you use?
Also, could you provide me a sample where the specific problem occurs so I can investigate where the problem is?
Hi all, i have found one solution. i have changed the file infragistics.ui.grid.filtering.js by letting Contains in the first condition push, and it worked.
Thank you and could you close this post ?
I am glad that you managed to resolve your issue.
Thank you for using Infragistics components.
