Hi Nerissa,
>Has anybody tried dropping a checkbox class in clistobj? The error says "Cannot add this object to a Grid". How can I select multiple rows in my grid then?
you tried to drag & drop from the project manager, right? That doesn't work. If you use the "Form Controls" toolbar instead, there won't be a problem to get a checkbox into the grid. Click the toolbar button with the library (?) icon on it, choose "Others" in the menu and select ccontrls.vcx Then you can select your grid column and put the MM checkbox class from the toolbar into the column. Afterwards you can remove the textbox that's already been in the column.
HTH,
Armin
