ThreeState Property for a DataGridBoolColumn Object

[mbutch]

I have a datagrid that gets populated with true/false info, but the checkboxes allow the user to click through all three states: true, false and null. I don't want them to be able to select the null state.

I format the DataGrid by Adding a table style. The true/false columns are formated using the DataGridBoolColumn object, but there is no ThreeState property to set.

How do I set the ThreeState property to false for the check boxes created for the datagrid?

Thanks,

Mike

You need to set the DataGridBoolColumn's AllowNull property to false.
