>How I can add controls to a column container in a grid, during design mode?
>I make the grid, set the ColumnCounts, but this only create columns with a Header, and a Text Box.... How I can create a Grid/Columns like the Order Entry example in Tasmanian Trade, with multiple controls in one column? Not in code, in design INTERACTIVE mode!

Right click the grid, and select the edit option.
Select the control u want to add from the toolbar.
Click on the desired column of the grid.

Also, the properties window is a good place to select
this or other controls contained on the grid.

HTH,
