Error Trying To Add To The Navigation Url Of A Hyperlinkfield
Apr 18, 2012
Am trying to add to the navigation url in a hyperlink field.
I have 5 columns on my gridview, the last being
<asp:HyperLinkField DataNavigateUrlFields="vID"
DataNavigateUrlFormatString="Page2.aspx?field={0}" HeaderText="send"
Text="send"></asp:HyperLinkField>
[Code].....
I had it working yesterday, but must have accidentally deleted the code, and I cant find where am going wrong here, I get an error "Specified argument was out of the range of valid values. Parameter name: index"

I am getting a "null reference exception" error when I run my application, this error occurs even before the webbrowser has navigated anywhere. Why would I get this error without a webbrowser document complete occurring?
vb
Dim HTML As String = WebBrowser2.Document.Body.InnerHtml.ToString
If HTML.Contains("Submit Comment") Then EnterData() Else NextURL()
End If
I don't understand why I would get this error when I haven't even navigated anywhere? Forgot to say that this code is inside WebBrowser2 document_complete.

I have gridview that I am using paging on. I want to pass along the current page in a asp:Hyperlink so I can send them back to the current page when they are done viewing the details of a record. Is this possible? If it is how can I do this?
<asp:GridView ID="grdObitList" runat="server" allowpaging="true"
PageSize="10" AutoGenerateColumns="false" CssClass="grdClass"
BorderStyle="None" GridLines="None" CellSpacing="2" >

In my ASP.NET Web Forms I would like to get the DataNavigateUrlFields from the HyperLinkField control.
In order to get the control I use the following code in the RowDataBound event:
If e.Row.Cells(n).Controls(0).GetType().ToString() = "System.Web.UI.WebControls.HyperLink" Then
Dim linkDownload As HyperLink = DirectCast(e.Row.Cells(n).Controls(0), HyperLink)
[Code]....
Is there any way to get the DataNavigateUrlFields property? In case there is not, is there any function to extract the downloadGuid value from HyperLink.NavigateUrl (in short treating the NavigateUrl as a QueryString)?

I am trying not to become intimidated or give up.I created a simple database and added stored procedures to read the data on a Windows form using Visual Basic in VS 2010.First I tried the Data Grid Example and all worked, I was able to view the data using a connection string to call the Stored procedure.I have stepped it up a notch by trying to bind data to form controls and I am getting this error message when I try to navigate through the data.
System.NullReferenceException was unhandled

I am using visual basic and when I try to hide Navigation bar, I am not able to, it is disabled. Ok I tried to turned it off going to "all languages", althought I unchecked the setting. It didn't disappear. I restarted visual studio, closed all open classes. It is just visual basic, when I try with c# I can hide and show it.

I'm learning WPF, and NavigationWindow in particular. I want to add stuff to the window, like a status bar, a favorite bar, etc. Unfortunately when I try adding anything, I get an error.
I'm hoping there might be a way that pages can be bookmarked as someone browses between them; let the user drag pages up to a favorite bar.
Something similar with the status bar; I'd like to have page specific information on the status bar, without having to have it on each individual page.
Is this possible with a navigation window, or am I barking up the wrong tree?
Edit:
<NavigationWindow x:Class="Window2"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
[code]...
I ended up putting the status bar on the individual pages, so that I can more easily change what's displayed from page to page, but the tool bar behaves nicely with the frame.

i made an application using VB.NET 2010. i have 5 forms. i want to know how to make one common navigation (like in a webpage) for this application. Is it possible to have the menu and header static and loads each form in one dynamic container. I hope my questing is clear :P just to make it more cleared, it is more like having a templates in php coding where we can load other page in a particular area without having to reload the entire page with each links.

I'm making a WPF form that has a large map as an Image in a ScrollViewer. It also has a mini-version of the map as another image. I want to make it possible to click the mini-version of the map to scroll the big version to a certain area of the map. So I need to do the following:
1. When moving the mouse over the mini-map change the mouse cursor to a square with the appropriate size to indicate what part of the map will be shown.
2. Scroll the big map to the appropriate section when the mini-map is clicked.
