Hiding an element from VisualBrush

Posted By:      Posted Date: September 07, 2010    Points: 0   Category :WPF
<StackPanel x:Name="MyPanel"> <Button>A</Button> <Button>B</Button> <Button>C</Button> </StackPanel> <Rectangle> <Rectangle.Fill> <VisualBrush Visual="{Binding ElementName=MyPanel}" /> </Rectangle.Fill> </Rectangle> In the above hypothetical code, would there be a way to hide one of the buttons from appearing in the Rectangle VisualBrush's fill? An attached property VisualBrush.IsVisualBrushVisible on one of the buttons would be cool, but doesn't exist. Any ideas?

Hiding radio button ListItem element


Hi all,

I have an ASP.NET page written in C#:

<asp:RadioButtonList ID="radioButtonListSelection" runat="server" AutoPostBack="True"
                            CssClass="label" OnSelectedIndexChanged="radioButtonListSelection_SelectedIndexChanged"
                            RepeatLayout="Flow" RepeatDirection="Horizontal">
                            <asp:ListItem Value="0"   >All Current</asp:ListItem>
                            <asp:ListItem Value="1" Selected="True">Pre Selected</asp:ListItem>
                            <asp:ListItem Value="2" >From Date</asp:ListItem>

I want to be able to hide some of the listitems, however there is no option to do this as I am only able to disable them.

I have read somewhere on the web that you can do this but the code is in VB :(

After after a solution in C#.






UpdatePanel is not a known element - message when upgrading to 1.0 ajax


It worked on one of my old pages.  I change the web.config, renamed all the <asp.

On some aspx page it doesn't recognize the updatepanel.  It only does on one page.  If I create a new aspx page with a different name - then it works.

Should I just create a new web project ajax - then copy all my code into there?  Or is there a way to get those old pages to recognize the new ajax controls?

Could not find default endpoint element that references contract 'CurrencyProxy.CurrencyServiceSoap



I created 2 projects in my solution:

  1. Classic asp.net web service (asmx)
  2. Class library project which references service
  3. web site project which references class library project
  4. Windows app project which references service.

Both projects were created in 3.5 framework and in Visual Studio 2008 Beta 2.

I added web service reference to Class library project. When it asked for namespace I typed "CurrencyProxy". Projects build ok, but when I run web app, Class library throws an error: Could not find default endpoint element that references contract 'CurrencyProxy.CurrencyServiceSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

I believe it has something to do with app.config in Class library project. Here is part from app.config:

<binding name="CurrencyServiceSoap" closeTimeout=

'element.className' is null or not an object



I just downloaded the project, compiled it and ran it right out of the box and when I put the mouse pointer over or remove the mouse pointer from either MenuItem in the menu demo, I generate this error:

'element.className' is null or not an object

It points to this javascript method:

updateClassName: function(operation, element, name, value) {
        this[operation + 'String'](
                function() {
                    return element.className;
                function(newValue) {
                    element.className = newValue;

Calendar hiding the last item in a day


Has anyone run into this? We have a calendar that, only on the 8th and 9th of the month, fails to show the last item:

It shows the hyperlink for "1 more item", but when you click it, it remains at "1 more item", rather than changing to "collapse". After verifying, there is one more item in the list that isnt getting displayed.

'Unspecified error' doing sp_xml_preparedocument on XML element with a long attribute

In SQL Management Studio 2008 (connected to SQL 2005 database), I get this:The XML parse error 0x80004005 occurred on line number 2, near the XML text "<item value="&#xD;&#xA;libname...Msg 6602, Level 16, State 2, Procedure sp_xml_preparedocument, Line 1The error description is 'Unspecified error'.When I do this declare @doc nvarchar(max), @idoc int set @doc = '<item value="&#xD;&#xA;libname..." />' EXEC sp_xml_preparedocument @idoc OUTPUT, @doc when the value of the @value attribute is actually a string of somewhat over 830000 characters.If I truncate the string somewhat, the statements execute successfully.Anyone know how to fix this?  (and "use shorter attributes" is not an acceptable answer :-)I would use XQuery except that I can't figure out how to get the equivalent of @mp:id and @mpparentid to give me the hierarchical structure information I need.  If anyone knows how to do that, I'd appreciate a hand there too!
