XmlDataProvider: Bind an XmlDocument with an XmlDataProvider

Posted By:      Posted Date: October 18, 2010    Points: 0   Category :WPF
 

I am trying to use a XmlDocument (xmlDoc) with a XmlDataProvider to bind the XML document to a control.

 

However, I get the error message "The resource 'xmldata' could not be resolved." In code-behind this is how the XML document is loaded with a string at runtime: xmlDoc.LoadXml(e.data)

 

 

Any hints on how to solve the issue would be highly appreciated.

 

Thank you

how to bind xmldataprovider in MVVM?

  

Hello everyone,

I am new in MVVM. I am trying to binding XmlDataProvider with a treeview. I have a XmlProvider in my view,and i want to bind its source property with a another property which is situated in my viewmodel class ie Filepath property. For that i am writing this code

<XmlDataProvider x:Key="xmlDataProvider" Source="{Binding FilePath}" />

but it shows this error

A Binding can not be set on Source property of type XmlDataProvider.Binding can only be set on  Dependency Property of Dependecy Object.

So how can I bind that Source of XmlDataProvider with the property which is in ViewModel?Is there any other solution for bind that property into View??

How to deserialize with XmlDocument and/or XmlDataProvider?

  

Hi. I have a set of classes set up that I have used in the past to deserialize with XmlSerializer:

	XmlSerializer serializer = new XmlSerializer(typeof(Foo));
	Foo foo = (Foo)serializer.Deserialize(stream);

What I would now like to do is embed that Xml in a Xaml file that is loaded at runtime using an XmlDataProvider:

	<XmlDataProvider x:Key="FooKey" >
		<x:XData>
		 ....
		</x:XData>
	</XmlDataProvider>

I'm loading the Xaml at runtime (it's a ResourceDictionary), extracting the XmlDataProvider and adding a callback for when the data has been loaded and is available:

	ResourceDictionary dictionary = (ResourceDictionary)XamlReader.Load(stream);
	XmlDataProvider provider = dictionary["FooKey"] as XmlDataProvider;
	provider.DataChanged += new EventHandler(provider_DataChanged);

My question is: in my provider_DataChanged handler, how do I deserialize that xml data given that XmlSerializer expects a str

XmlDataProvider error in XAML

  

Hi.

I'm trying to bind to some XML in an XmlDataProvider, defined declaratively in the XML thus:

    <XmlDataProvider x:Key="ImageData">
      <data xmlns="" >
        <text>TEXT</text>
      </data>
    </XmlDataProvider>

Cider's giving me an warning, saying the XML elements within the data provider are invalid child elements, and if I switch to design view I get an 'Error reading the designer file' message. If I take out the <data>...</data> XML, leaving the data provider, it's fine.

The XAML above has been tried in Window.Resources and Grid.Resources.

I'm stuck. Any ideas?

.NET Reflection: Dynamically Bind Your Data Layer to Stored Procedures and SQL Commands Using .NET M

  

One major inconvenience of using SQL stored procedures from code is having to match type information. You have to write long wrapper functions around the procedures just to expose the data types. In the .NET Framework, however, the reflection services of the System.Reflection namespace allow you to query rich metadata that describe data types. This article explains how to use reflection in .NET to end your stored procedure nightmares. The author creates four custom classes, including one that generates a SQLCommand object based on the metadata of a method. Using this library, you'll be on your way to automating the generation of stored procedures.

listview 3.5 bind dropdownlists edit item template VB.NET

  

I am trying to do this with many issues of data binding doubling the amount and not setting selectedValue on dropdownlist. I have read some posts and they help but I am missing a crucial piece. My problem is that my dropdownlist is doubling the amount of records for the dropdownlist. Instead of "YES;NO;SELECT A VALUE", I am getting "YES;NO;SELECT A VALUE;YES;NO;YES;NO". My database is correct with the UPDATE part but the rebind after update is failing horribly.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If IsPostBack Then
            If Session("ACTIVETAB").ToString() = Session("SUBCONTRACTSATABNO").ToString() Then
                BindData()
            End If
        Else
        End If
    End Sub

    Public Function loadlookups(ByVal id As String, ByVal e As System.Web.UI.WebControls.ListViewItemEventArgs) As DataTable
        Select Case id
            Case "ddlCertReceived"

                ddlCertReceived.DataSource = dt

Formview + EditItemTemplate + Bind + PageLoad + Prerender = Confused

  

I am working with a formview edititemtemplate.  Currently in my page load, i have some stuff that would show or hide certain panels based on dropdownlist values.  These dropdown values get binded during page load.  I need to be able to change the values/dropdowns, without rebinding the old data, and updating the visibility of the panels based on predefined rules.

I have experimented with putting my formview.databind() in page load if isnotpostback, in prerender, in prerender if isnotpostback.   I have tried my rules (ex if ddlState.selectedvalue = "DE" then pnlDelaware.visible = "true") in the page load, and the page render.   I'm just not sure how to get the stars aligned here.

The closest i have come is having the databind in the pageload if notispostback, and the rules in the prerender.   However I get an error "dropdownlist has a SelectedValue which is invalid because it does not exist in the list of items.

Thanks!
