hi everybody
i am facing a problem with dbgrids.
i am using a single grid for displaying data of different tables. each table is having different number of fields.
so when assinging the query to the grid at runtime ... in some tables where number of fields is less empty space is left at the right of the grid .. and when the number of fields are more a horizontal scrollbar appears on the grid.
i want my form size to remain the same.
i hope the question is understood.

thanks in advance

>i hope the question is understood.
not really, what is wrong with the scrollbar and the free space(if there are less columns)?
thats a kind of dynamic, which keeps your form in the current metrics

nevertheless you can adjust the column-width like (preferable in the afteropen-event of your dataset)

  dbgrid1.Columns[index].Width := ...

no, not as i know ->
you have to calculate the width byself depending on count of fields and type of field

cumbersome??? Asmita, if you think this way, there is NO way.

You don't need to know the width of all fields. You can write a generic routine which can work for all tables. Let me know if you need more help on this.
