Your code would change it and then Delphi would immediately change it right back. If you un-commented the height line above. That minimum height is larger than the height of the cell. The reason is that the LookupCombo has a minimum height. Left ).ДЄlso notice that the Height of the LookupCombo has been commented out above.

Left ) into the form plus the offset of the cell into the grid (Rect. So, for example, the left side of LookupCombo needs to be the offset of the grid ( DBGrid1. Notice that the position is determined relative to the form not to just the grid. Further if it 's the highlighted cell and the cell has the same field name as the lookup combo's datafield then we need to move the LookupCombo over that cell and make it visible. The code is saying that if the State parameter is gdFocused then this particular cell is the one highlighted in the grid. The reasons for the excessive use begin / end will become clear later in the demo. Set the LookuoCombo's properties as follows. Now go get a TDBLookupCombo from the Data Controls pallet and drop it any where on the form, it doesn 't matter where since it will usually be invisible or floating over the grid. Drop in a second data source and set its DataSet to Table2. Set it 's Alias also to DBDEMOS, TableName to CUSTOMER.DB and Active to True. The first control we are going to put into the grid is a TDBLookupCombo so we need a second table for the lookup. The data from GRIDDATA.DB should appear in your grid. Go back to the grid and point it 's DataSource property to DataSource1. Drop in a DataSource and set it's DataSet property to point to Table1. Next drop in a TTable and set it 's Alias to DBDEMOS, TableName to GRIDDATA.DB and set the Active property to True. So start an new project and drop a DBGrid into the main form.

The techniques described below to anything that is termed a visual component. By component I mean anything from a simple combobox to a more complicated dialog box. This article and the accompanying code shows how to put just about any component into a cell on a grid. Q : How do I put components into a TDBGrid ?ДЄ : I saw this on compuserve and it is great !
