I have a grid and in the grid there is a column with dropdown. I define in the code like:

this.grid.DisplayLayout.Bands[0].Columns["columnName"].AutoCompleteMode = Infragistics.Win.AutoCompleteMode.Suggest;

this.grid.DisplayLayout.Bands[0].Columns["columnName"].FilterOperatorDropDownItems = FilterOperatorDropDownItems.Contains;

the name of the column is correct and when i try to write a name of the value that im looking for it just jumps directly trough the values that start with the letters that i input.

eg. if i try to write "ST James Hospital" , when i press "S" it goes to ST James Hospital , but when i press the "T" it goes to another item that starts with "T" like Talbot lodge.
