CheckBox Column in a DataGrid ?

// Does anyone have a working example of how to create a
// DataGrid containing a column of CheckBoxes? The code
// below is clearly not working -- "True" shows in the
// first column (the bool column), rather than CheckBoxes.

// TIA, Jim H.

// Note that Column1 of the recStruct is type bool

Hi JimH !

Do you find the solution ( how to add CheckBox or other control to
DataGrid ) ?
Please mail me.

Thanks,
Stan
