I've made DataGridView on my Form1(data from database i've made). And i did an event,when someone doubleclicks that row marker(that left side empty cell,when you mark all row) it opens up my Form2. I can't find a way to export those vallues(strings) in cells of selected row to my Form2,so i can use them there.

how to make DataRows in a DataTable ReadOnly? You can set DataColumns ReadOnly, but not DataRows?
I'd like to bind a DataRow ReadOnly property to my DataGridViewRow ReadOnly property. So when my DataGridView displays the underlying DataTable, if the DataRow is ReadOnly then the DataGridViewRow would automatically be ReadOnly as well. how to do this other than the way I do it below?
For Each r As DataGridViewRow In Me.dgvCurrent.Rows
If r.Cells("curAnalyteID").Value <> Me.cbxAnalyte.SelectedValue Then
Me.dgvCurrent.Rows(r.Index).ReadOnly = True

I'd like to partition my search results (which is in a DataTable) into groups of say 100 so the user navigates through them a chunk at a time.I thought I could bind an array of DataRows to a DataGridView as the DataSource but it just does not work. This is the code I tried
DataGridView.DataSource = (From r In DataTable.Rows Skip 200 Take 100).ToArray()
I'd like to stay away using the DataGridView's VirtualMode.
I am trying to use the Select on a datatable and am having some trouble. I got it to find a match on rows in a datatable I fill with data in multiple columns. But I cannot seem to loop through the results to do something with it. Here is my code below. The table is already filled with data.

I've got a bindingsource that has a datasource of a datatable
capabiltiesBS.DataSource = vendorBAL_C.capabilitiesTable
And that table looks like this
Select VendorId, Capability, LanguageFrom, LanguageTo From VendorCapabilities_T
At any rate - I do this to filter the binding source and then thought I could loop through the datarows and fill a tree view with them
capabiltiesBS.Filter = "VendorId=" & VendorId
For Each cdr As DataRow In capabiltiesBS.List 'vendorBAL_C.capabilities.Table.Rows()

i have a many-to-many relationship table in a typed DataSet.For convenience on an update i'm deleting old relations before i'm adding the new(maybe the same as before).Now i wonder if this way is failsafe or if i should ensure only to delete which are really deleted(for example with LINQ) and only add that one which are really new.
In SQL-Server is a unique constraint defined for the relation table, the two foreign keys are a composite primary key. Is the order the DataAdapter updates the DataRows which RowState are <> Unchanged predictable or not?In other words: is it possible that DataAdapter.Update(DataTable) will result in an exception when the key already exists?

We use a small bit of excel exporting code in our app code at work to export XML controls from our ASP pages into an excel format using the following code:
Public Shared Sub Export(ByRef xml As Xml, ByVal filename As String)
Dim response As HttpResponse = HttpContext.Current.Response()
response.Clear()
[code]....
This is all fine, except we've encountered a rather frustrating bug. If the XML control has a link in it then the export code is called again. We have a button which will say "Export to Excel" from the .aspx page which simply calls ExcelExport.Export(Xml1, "MyFileName") which is in a LinkButton click event.Here's the order of events based on the form submit (selecting filters)
Enter filters
Submit form
Page_Load occurs
[code]....
So the user submits a form which loads up the XML control in a nice viewable XSLT page. Then they click "export to excel" which will give them the page in excel instead, then they click on the XSLT page, for example a link, but the save dialog for excel comes up again. We've gone through the series of events, and if we do not call the excel exporter it goes through the series of events as normal. If we do call the excel exporter it will go through the page load event and unexpectedly go into the link button click event.
