You can enable de Filter bar in CxGrid doing the next steps:
At the Object Inspector you must change some properties
Step 1:
At the DBTableView.FilterRow property change:
DBTableView1 - FilterRow - ApplyChanges = fracImmedialety
DBTableView1 - FilterRow - Visible = True
DBTableView1 - FilterRow - InfoText = to add the text "Click here for filter creation (for substring search, begin with * character)"
Step 2:
At the DBTableView.DataController property change:
DBTableView1 -DataController-Filter-PercentWildCards = * ( will put instead of percent a star)
DBTableView1 -DataController-Filter-Options-fcoCaseInsensitive = True (any register)
