I have a datagridview that has checkboxes in the first column. When a checkbox is checked the row gets selected. Only the row also gets selected if I click anywhere else in the datagrid. I would like to set datagridview.selected = $false, only that also prevents the ability to check the checkbox.

Thanks

That is correct. If you set full row select then a click anywherere selects the row.  Down' set full row select.

But I want to select the full row if the checkbox is checked, not when I click anywhere else.

That is how you have to do it then get the checked event and manually select the entire row.
