Positioning a combo box in a DBGrid cell & making validations

[daneb]

Hi.

I have a dbgrid in my form containing 10 columns displaying records from an Access table. It is required that in the 10th column, instead of the user inputting a value, he/she will select a value from a combo box. This is true for all rows of the 10th column. This will ensure that only valid values will be entered. How can I put the combo box in a particular cell of the 10th column?

My second question concerns validations for those cells that will not use a combo box. Say the numeric input values in a certain column require to be of a certain range only, how can I validate the inputs? What events of the dbgrid will I use to make validations?

Thanks for the info in advance!

Thanks for the reply. I saved the code you posted for future use. However, my current problem lies in the fact that a dbgrid cannot contain a combo box, so I have to device a method on how to put combo box in the dbgrid cell where the user wishes to make an input, in this case all of the cells of the 10th column. But of course, it will be costly to put a combo box for every cell of the 10th column, and besides, the number of rows needed to retrieve the records from my database will vary. Therefore, a single combo box is employed and will be positioned in the cell that the user chooses; and this is my foremost problem. Any more ideas?
