and also in my grid columns are dynamically loaded, I have not assigned the fields to the store or and the store to the grid because I do this uploading them via respective web service, that is to say, I have a routine to assign the store fields dynamically and create grid columns also and the bind the grid to the store, reviewing information on the console the data is retrieved but grid loads a blank information as if they bring the records but it's not binded and can not display them. Any suggestions?
1. Post code in code tags
2. Post all related code, easier for community to help you then reading a big messed up phrase
3. Best practices recommends to name classes with first and last namespace with first letter uppercase. In your case would be: VWD.store.Datoms
4. You bind the store to grid , not opposite.
