Nested Gridviews

Chris

I am creating a nested gridview as per the tutorial here
(http://msdn2.microsoft.com/en-us/lib...8(vs.80).aspx). My
gridviews work fine. I have a master gridview containing the customerid.
This value is used by a a detail gridview nested within the master. This
works well but when I hide the customerid the filter stops working. I
suspect that this code can't find the ID to do the filtering. How do get
around this as I want to hide the CustomerID. Also how efficient is this?
Does it involve a separate call to the database for each row in the parent.
Is it possible grab all the child detail data in one go and filter via a
dataview. I quite like using typed datasets and the objectdatasourc e but I
don't want ineffiicient code. Regards, Chris.

Protected Sub GridView1_RowDa taBound(ByVal sender As Object, ByVal e As
System.Web.UI.W ebControls.Grid ViewRowEventArg s) Handles
GridView1.RowDa taBound

If e.Row.RowType = DataControlRowT ype.DataRow Then

Dim o As ObjectDataSourc e = CType(e.Row.Fin dControl("objds getorders"),
ObjectDataSourc e)

o.SelectParamet ers(0).DefaultV alue = e.Row.Cells(0). Text

End If

End Sub

I found another way but if anyone has any opinions on the other questions
they would be welcome.

o.SelectParamet ers(0).DefaultV alue =
GridView1.DataK eys(e.Row.DataI temIndex).Value

"codeless" nested gridviews...there has to be a better way

by: Roy | last post by:

Hey all. Below is the nested syntax on how to make a "codeless" nested gridview embedded within another gridviews templatefield column. Only problem is that it loads slow. REAL SLOW.

I am new to 2.0 and am using nested gridviews. The first one contains category information, the second is based on a query from a product table.

I had it in tables and aligned correctly, but now that I am nesting the gridviews it is not allowing me to do this. I would like to go to a new line after the category, and...

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
