DataGrid Checkboxes Behaviour

[Nagabhushan Ammu]

Has anyone tried this.

Take any table in a database (ex. Customers Table in the Northwind
database). and add a new column to it called test. let the data type of test
be "bit".

do a select * query on this new table and display the results in a DataGrid
Control.

You will see check boxes in the columns of this field. try clicking on these
check boxes to check and uncheck a box. you will notice that it takes 2
clicks to uncheck the box. on first click the cell turns gray
and on the second click the box is actually gets unchecked. this behaviour
is annoying as the box should change state in just one click.

It will be very kind if someone tries to simulate what I have done and let
me know if the same problem is occurring. Is this a bug... Can there be some
workaround for this ?

I'll be very gratefull for any help/comments

Re: DataGrid Checkboxes Behaviour

For one-click checkboxes you need to override OnMouseDown() routine of your
grid
