ChangePropertyAction to modify Visibility not working in ListBoxItem DataTemplate.

Posted By:      Posted Date: September 28, 2010    Points: 0   Category :WPF
I am trying to change the visibility of a control in a ListBoxItem template (based on it beeing selected in the parent listbox) through a ChangePropertyAction but the code below does not work. I tried fiddling around with setting the TargetName on the trigger or setting the default visibility of the control through a style. I debugged the Binding through a DebugConvert and checked that the IsSelected is correctly set to true but it still does not work. Can anybody explain to me why this is not working and how I can fix this?

Working with SharePoint document libraries

Document libraries are collections of files that you can share with team members on a Web based on Microsoft Windows SharePoint Services. For example, you can create a library of common documents for a project, and team members can use their Web browsers to find the files, read them, and make comments. Users with Microsoft Office 2003 can check out and edit the files as if they resided on a local or network drive.

By default, your team Web site comes with a built-in document library named Shared Documents, which is listed on the Quick Launch bar as well as on the Documents and Lists page.

Server side validation of Fileupload control not working



I've tried this method in my code behind to try and validate that the Fileupload control has a file or not. I get the error message the the event "Server Validate" cannot be found. Can anyone tell why? Thanks.

Public Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate

' Get file name

        Dim uploadAvatar As FileUpload = DirectCast(AdvertisementForm.FindControl("uploadAvatar"), FileUpload)

        Dim UploadFileName As String = uploadAvatar.PostedFile.FileName

        If UploadFileName = "" Then
            ' There is no file selected
            args.IsValid = False
            Dim Extension As String = UploadFileName.Substring(UploadFileName.L

Row command working on all rows not selected one?



I have this code that hides a column in a gridview.  (The column houses another nested gridview).

    Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
        If e.CommandName = "Select" Then
            If GridView1.Columns(0).Visible = False Then
                GridView1.Columns(0).Visible = True
                GridView1.Columns(0).Visible = False
            End If
        End If
    End Sub

The trouble is that if I click the select link on one row that action to hide is carried out on all rows.  How can I set this up so that it only hides the row that is selected?


Tab container rendered with visibility:hidden - This was reported over three years ago.



Here is (more) code that demonstrates the issue.  If the control in the host page is removed the tab control renders correctly.  Otherwise it is rendered with the visibility attrubute set to hidden as reported in the above link.  Is this broken or am I doing something wrong?

Keyboard shortcuts stops working in WebMatrix


I'm often experiencing that keyboard shortcuts stops working in WebMatrix. This is very annoying as CTRL-S, CTRL-C, CTRL-V, etc. stops working, all of which are heavily used when programming. It's obviously hard to explain how to reproduce this, but I was wondering if someone knows a quick-fix?

How to modify the login control



I'd like to record more information than the default control allows as well as perform actions with the input when the form is submitted but I'm having trouble figuring out how.

So firstly, if I want to record the middlename for example, how would I do that, and by default, where would it go if anywhere?
When the form is submitted, I'd like to take specific input, such as just the middlename for example, and write some linq to sql code to specify when and how it's stored.
In what event would I put this code?

New off line application working with sdf file. Need advice


Hey Folks

I am working on a project currently where I need to get data out of a 3rd party vendor's software that uses a .sdf file I looked this up and its a SQL CE file. I was hoping to just link to with with access but thats apparently not going to happen. I need to link to the database extract data from it to a csv file for later use. I also and most important I need to get the data from it and create a report that can be printed while on a customers site that my or may not have web access so I need for this program to be on and off line. I had my webapplication that I have been working on open and was able to bring up the sdf file under the server exploere however I can't seem to get anything out of it when I try to do grid views or detail views errors out.

Can I use one of Visual Studio projects to create this sort of applicaiton if so what would be the best approach. I would love to get an access odbc driver since office is allready installed on the employee's laptop's

URL Rewriter.net - not working



I have a website that uses Querystrings to determine what content to show on a page. I would like to be able rewrite these URL's to become Search Engine Friendly URLs. So for example I would like to change http://www.website.co.uk/Company/Company/Conference.aspx?WebPage=ImportantDates to http://www.website.co.uk/Company/Company/Conference.aspx/ImportantDates.

I have been reading the following article by Scott Gu - http://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx - who suggested using a HTTPModule such as URL Rewriter.net (http://urlrewriter.net/).

So I have done this and added the URLRewriter.dll file in my bin directory and altered the web.config (following Scott Gu's approach #2). However my URL's are not changing and I don't know what I am doing wrong. I have added the following in the web.config to try and change the URL's.


    <rewrite url="~/UKAIS/ConferenceWebPage.aspx?WebPage=(.+)$" to="~/UKAIS/ConferenceWebPage.aspx/$1" />

However my webpage URL remains with the ?WebPage querystring.

I am really stuck and any help would be very much appreciated.



Localization not working in class library (composite control)



I have a class library called WEM.portal which used Resource files to localise text in my composite controls.

I store my resource files (eg MyResourceFile1.resx) in App_GlobalResources folder and then refer to them using

MyLabel1.text = My.Resources.MyResourceFile1.MyResourceKey1

This is all working ok until I create seperate files for each language such as MyResourceFile1.FR-fr.resx.

I have implemented this throughout my other web applications but the Class Library doesnt seem to want to work the same way

When I load the page it correctly showes the resourced keys which I have done through the web application BUT the resource keys in the composite controls does not seem to pick up the culture code.

Am I missing something stupid. Ive tried

  • changing the Build Action on the resource file to Content and Custom tool to GlobalResourceProxyGenerator
  • Creating a resourceManager but to no avail

System.Drawing Image imgProd = System.Drawing.Image.FromFile(ImagePath);

if(imgProd.Height > 200)

imgInfo.Height = 100;




imgInfo.Height = 200



WHen I run this page I am getting the folloiwng error
