Add datagrid filters instead of using the columns filters

[randibrahim]

One of the issues I have notice is that to do a filtration on the datagrid, you have to add column to the grid and use the toolbarfilter of that column to do the filtration...

Me and my friend thought about adding a new filters, those filters are added to the grid as columns did, and are rendered on the top of the grid... so, we can get rid of the columns and use those filters to get the required data...

In this case, we don't need to show the columns that we want to filter, but at the same time we can filter the grid based on them using the added filters
