GridView1.SelectedRow Returning Nothing
Sep 13, 2010
My problem is that in the below code, the SelectedRow property returns nothing. I manually bind items to GridView at runtime and autogeneratecolumns and autogenerateselectbutton properties are true.
I think the problem is about having a PostBack when the Select command is clicked.
Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
Session("ContactID") = GridView1.SelectedRow.Cells(0).Text()
Response.Redirect("~/ContactAddress.aspx")
End Sub

I have a GridView which is showing results and from which I am deleting a result using the auto-created delete link. My code behind to remove the row and associated info. is:
Private Sub GridView1_RowDeleting(sender As Object, e As System.Web.UI.WebControls.GridViewDeleteEventArgs) Handles GridView1.RowDeleting
' The deletion of the individual row is automatically handled by the GridView.
Dim dbDelete As New pbu_housingEntities
' Remove individual from the bed.
[Code] .....
It seems that it is not able to grab the row that is being deleted, so it is always giving me a "Object reference not set to an instance of an object" error.

im tryin to link the 2 pages to each another, 1st, when i click on the View hyperlink in the product page, its supposed to lead me to the product view page, with the product chosen being displayed. Ive searched the net, and well, ive found some solution on this, but most of them were to update the statements, for my case it would be just to lead from the product page to the product view page. But everytime i press the view link, it leads to an error.
The source code is as below
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="productid"
DataSourceID="SqlDataSource1">

My brain may just be fried since it's the end of the semester, but my teacher kicked this back to fix and resubmit...she said that I am "returning the name of your function rather than your variable name".
Here is my code for all 3 forms.

So I have a pretty simple UDF written in visual basic for use in excel. It calculates your approx. taxes. Lets say I use it as such: =Taxes(I23-I18,I24-I20,"Married")
If I type this in it works great. Now if I save the sheet and restart excel the cell now says #VALUE! If I select the formula and hit enter once again it recalculates it fine. What am I doing wrong? Application.Volatile shouldn't be needed but I was trying ideas. [Code]

This might seem like an insanely easy question, but I cant seem to find an answer anywhere to it. I'd like to think that I am decent at VB but while I was learning javascript the other day I found something that seemed awesome and now I cant figure out how to do it in VB.in javascript it looks like this
var someValue = getThatValue()Its both calling and setting the value from the getThatValue() sub. what is the VB equivalent?

I have a piece of code that checks a time and then adds hours based on the daylight savings time value.
Dim CommentDateTime as Date = "11/2/2010 8:21:42 PM"
If CommentDateTime.IsDaylightSavingTime Then
'do something
Else
'do something else
End If
The problem that I'm having is that IsDaylightSavingTime behaves differently on the production server than it does on the development.On the development server the case is TRUE, but on the production it is false.
Both servers are running the same OS and are both running .NET 3.5

I have an XML file that sits on the hard drive of a Server running my Web Service. I need to access that file from another application.
This is my method on my Web Service
Public Function getXMLFile()
Dim xmlDocument As System.Xml.XmlDocument
xmlDocument = New System.Xml.XmlDocument()
[Code]....
This is caused when I try to return the xmlDocument object
From the information I gathered, it's like SOAP wants to wrap my XML in more XML and stops me from doing that.
How do I go about getting the XML File from my Web Service if I can't return XML?

Thanks William, that was the ticket. Had to assign the name property on both ends [DataTable.TableName].
On a side note here: There appears to be some school of thought (no offense Marc) that the following statement is always true:
"Everything in the world can and should be made into an object."
It is, simply, not always true. There are cases where you cannot cram your 'object' into any cookie-cutter or class no matter how you try to customize it. For me to objectize this beast, I'd have to create roughly 4,000 objects. I don't have time to do that, and yet this project must run as a service. Frankly I think the developers at MickeySoft need to get out more into the real world, and see for themselves that although theory is great it does not represent true-life challenges. I am all for working with objects for the obvious benefits, but there is a reality that universals do not exist. In my trade, even 'most of the time' rarely happens.
Before they push out a new technology set, and cease support of an old one, they need to make sure that the new technology has the same capabilities the old one had.
For the record: The people who believe the above statement to be true are also the same people who would refuse to take the project I'm currently working on.
Just the same -- thank you both for your time, efforts and opinions!
I'm trying to create a WCF function that will return a table to my console testing app. I am a total noob. The data is 2-dimensional and looks like this:
23 Letter
42 Another Letter
43 Document
[Code].....
...Of course, it won't work. I just need to get the WCF to pass a basic table to my console application. The execute SQL seems to work just fine, I just can't get the data back to my application.

I want to return a value (vbCancel or vbOK) from a form which is shown as a dialog from the calling form.So, I overloaded the showdialog method to return the value.Trouble is, a value of zero is returned as soon as the form is shown.Now, if I can make it behave more like the showDialog method where execution doesn't continue until the form is hidden everything would be fine.

How can this be so difficult and why? Returning simple XML with no Name Spaces and an XML decaration. Creating the XML using XML Writer is easily done and if I output it to a file then great. How on earth can you return the contents via WCF. Using an XML Element is no good as you loose the XML declaration and using a string is no good as the output is wrapped up in a <string> element. Can't return an XML Document as it can't be serialised.I know that there are many posts on this site, but none answer the question. I am using VB.NET (boy I wish I had the time to learn C#) and I cannot get the Data Contract to work either even using IXmlSerializer. An example of the output I need to send back via WCF

I have a SQLite database and I am tyring to query the max value in the RecordID field. This query works when I run it in SQLite but I can not get the VB to return the value, what have I done wrong?
Dim getMaxRecID As String = "SELECT MAX(RecordID) FROM String"
Using cmd1 As New SQLiteCommand(getMaxRecID, pConn)
cmd1.CommandType = CommandType.Text
Dim IDresults As Integer
[code]....
The connection is correctly opening the db, and shows it as open as well. No error, just IDresults returns 0 everytime.
