vsflex 3.0 problem

Hi all,

a) I am using vsflex 3.0 in my app. I have set one of the columns to use checkbox in the grid during form load as following simple code:

With vsgrid1
.ColDataType(2) = flexDTBoolean
End with

But the checkbox always shows in first row and first column no matter i have indicated third column to use as checkbox. How can i solve it? or any other flexgrid i can use to achieve it?

b) During loading data to grid, will the checkbox in the third column shows up automatically according to the number of records loaded?

Thanks.
