I have a dataset with 3 tables -- 2 Parent tables and 1 table that is a child
table of both the parents. I create a dataview on the child table and set
the rowfilter to a value which filters the child based on values in both
parent tables. When I edit the parent tables the edit is not reflected in
the dataview.count property. How can I force the dataview to refresh
following parent table edits?
For example:
Parent1
Parent1ID Included Selected
1 0 0
2 0 0
Parent2
Parent2ID Included Selected
1 0 0
2 0 0
Child
ParentID1 ParentID2 Value
1 1 foo1
1 2 foo2
2 1 foo3
2 2 foo4
dv = new dataview(child)
dv.rowfilter="P arent(Parent1Ch ild).Included = True AND
Parent(Parent1C hild).Selected = True AND Parent(Parent2C hild).Included = True
AND Parent(Parent2C hild).Selected = True)"
dv.count = 0
I edit Parent1 so that Parent1ID 1 is both in included and selected and
Parent2 so that Parent2ID 2 is both included and selected.
dv.count is still 0. Why?

Pat,
A DataView is just an other word for the DefaultView in a DataTable, it
reflects all the data conform the options you have set.
You can create more DataViews for a DataTable then one DataTable, therefore
beside the defaultview there are DataViews, however they return only the
data that is in a datatable, conform that datatabe. Moreover a DataTable is
dynamic every change is direct procesed (there was a bug about that in
version 1.x, so as you are using that, you have to go around that).
Therefore look at your datatable, and for sure not to the dataview.
To see what is not showed, simple start with a dataview and add piece by
piece the elements for your rowfilter.

I am editing the datarows through a structure like:
dim dr1 as dataset1.Parent 1Row
dim dr2 as dataset1.Parent 2Row
dr1 = dataset1.Parent 1.FindByParent1 ID(1)
dr1.BeginEdit
dr1.Included = 1
dr1.Selected = 1
dr1.EndEdit
dr2 = dataset1.Parent 2FindByParent2I D(2)
dr2.BeginEdit
dr2,Included = 1
dr2.Selected = 1
dr2.EndEdit
And yes, I am using framework 1.1. What is the best workaround?

Pam,
For you start with a work around for the dataview. The EndEdit was as well
(but then completely) a bug in version 1.1, you can simply go around that by
using the EndCurrentEdit which is commenly used for that in 1.1. Before
there was 2.0 I even did not know it was a bug, I simply used forever the
EndCurrentEdit.
I think you better can try that first.

Not sure what group this question is better suited for so I sent it to both.
I have a DataTable which contains 1545 rows. I have a method that returns a
DataTable of distinct rows based on one column. This table ends up with 386
rows.
I need to loop through the smaller table and filter a DataView based on each
row from this table.
This loops takes ~5 secs. Is there anyway to improve this?
