Linq To Datarow, Select Multiple Columns As Distinct?
Apr 16, 2010basically i'm trying to reproduce the following mssql query as LINQ
SELECT DISTINCT [TABLENAME], [COLUMNNAME] FROM [DATATABLE]
the closest i've got is
Dim query = (From row As DataRow In ds.Tables("DATATABLE").Rows _
Select row("COLUMNNAME") ,row("TABLENAME").Distinct
when i do the above i get the error
Range variable name can be inferred only from a simple or qualified name with no arguments.
i was sort of expecting it to return a collection that i could then iterate through and perform actions for each entry. maybe a datarow collection?
As a complete LINQ newb, i'm not sure what i'm missing.
i've tried variations on
Select new with { row("COLUMNNAME") ,row("TABLENAME")}
and get:
Anonymous type member name can be inferred only from a simple or qualified name with no arguments.
to get around this i've tried
Dim query = From r In ds.Tables("DATATABLE").AsEnumerable _
Select New String(1) {r("TABLENAME"), r("COLUMNNAME")} Distinct
however it doesn't seem to be doing the distinct thing properly.

View 5 RepliesBinding Datarow To Textbox.?
Dec 16, 2010I have the following code where I'm trying to bind a datarow to a textbox.
Me.TierNameText.DataBindings.Add("Text", Me.m_TierRecord, "tier_name") Problem is, when the form is displayed no text is shown in the textbox.
This code runs before I call the form's ShowDialog method. I stepped through the code to make sure the datarow has data, and indeed it does.
I rarely use databinding but thought I'd try it this time.

Sep 9, 2010I'd like to see how others might handle this scenario and perhaps provide some comments on this particular solution for handling null values. I have run into a situation where my application requires data from an ancillary source that cannot be altered/changed, which of course means dealing with poor database architecture and implementation! In this case, my app is running into errors when attempting to set some form controls (textbox) to values from a single ADO.NET DataRow. Perhaps I should be handling this when attempting to set the controls? Not sure, but here is the current way this is done:

Updating A Datarow With Another Datarow?
Apr 28, 2010I have two datatables with similar structures that I want to make one existing row to be updated from another datatable.
For example, "tableA" has three columns: "one", "two", and "three"; with "one" being the primary key...
and "tableB" has three columns as well: "one", "two", and "three"; with "one" being the primary key.
Say there is a row on tableA that is different than a row on tableB (with a matching primary key). What I wanted to do, as efficiently as possible, is to take the that row from tableB and replace the one on tableA so it'll be modified.
I'm not sure if there's an easier way of doing that instead of using loops for setting the row's items.
