Filtering of BindingSource

[Guest]

I have a DataTable with four columns of type Float (r1, r2, r3, and r4)
connected through a BindingSource to a DataGridView. I need to filter the
displayed rows as"

ABS(r1-r2)>c1 OR ABS(r3-r4) > c1

where ABS is an absolute value.

Is there a simple way to accomplish this while retaining the ability to edit
the data in the displayed rows?

Best regards;

Try this expression for the BindingSource.Filter property.

bindingSource1.Filter = string.Format("(IIF(r1>r2,r1-r2,r2-r1)>
{0}) OR (IIF(r3>r4,r3-r4,r4-r3)> {0})", c1);

The above assume c1 is some paramater value. If c1 is a column in your
datatable, then try

bindingSource1.Filter = "(IIF(r1>r2,r1-r2,r2-r1)>c1) OR (IIF(r3>r4,r3-
r4,r4-r3)>c1)";

Hi Arlyn,

I aggree to what Clay has suggested. In fact, I have performed a test on
Clay's solution and confirmed it works.

While we set the Filter property of a BindingSource component, we could
still edit the data in the displayed rows. The two things don't conflict.

Hope this helps.
If you have any question, please feel free to let me know.

Sincerely,
