DataGrid not populating with binding

DataGrid not populating with binding - c#

I am trying to populate a DataGrid with an SQL query, and then be able to filter the datagrid. So far I have this:
XAML

try

public DataTable SqlConnect(string query)

string sqlQuery = query;
ohsql1 = new SqlConnection("Data Source=OHSQL1;Initial Catalog=Reporting;Integrated Security = true");
DataTable table = new DataTable();
try
{
//connect
ohsql1.Open();
//fill datatable with results
SqlDataAdapter a = new SqlDataAdapter(sqlQuery, ohsql1);
//fill table
a.Fill(table);
//kill connection
a.Dispose();
ohsql1.Close();
}
catch (SqlException e)
{
Console.WriteLine("SQL ERROR: " + e);
}
return table;
}
private void MenuItem_Click(object sender, RoutedEventArgs e)
{
_filterString = FilterBox.Text;
if (_filterString == "")
{
Console.WriteLine("no filter");
return;
}
else
{
Console.WriteLine(_filterString);
FilterCollection();
}
}
private void FilterCollection()
{
if (_dataGridCollection != null)
{
_dataGridCollection.Refresh();
}
}
private bool Filter(object obj)
{
if (obj is DataRow data)
{
if (!string.IsNullOrEmpty(_filterString))
{
return data["CUNAME"].ToString().Contains(_filterString);
}
else
{
return true;
}
}
return false;
}
The "CUNAME" column specified is just a test, eventually I want to have it know which column the filter button was pressed on.
The problem I am getting is that the DataGrid is returning empty. When I do Grid.ItemsSource = pixsellOrders.DefaultView (or something to that effect, can't remember the exact syntax) it works fine and populates the grid.
I have tried changing to a List which would definitely be IEnumerable but that wasn't populating the data grid either. Adding AutoGenerateColumns (either to true or false) has no effect. No errors are being shown in the output. Commenting out all the filter parts also has no effect. Removing the Context menu also has no effect. Removing AsEnumerable() has no effect on the grid population but throws and error at DataGridCollection.Filter.
Can anyone see where this is going wrong? And if you can advise how I might go about getting the column name to check (rather than hard coding all columns) that we be really helpful as well)
Thank you in advance

Set the DataContext of the Window to itself:
public PixsellOrders(string windowTitle)
{
InitializeComponent();
DataContext = this;
//...
}

How can I change the default style of my DataGrid's headers?

I have a WPF window that contains nothing but a named DataGrid.
<DataGrid x:Name="DGResultset"/>
I populate it with the contents of a DataTable that gets its own contents from the resultset of a SqlDataReader.
public DataDisplay( DataTable resultSet )
{
InitializeComponent();
DGResultset.ItemsSource = resultSet.DefaultView;
DGResultset.AutoGenerateColumns = true;
}
How can I change the default style of the headers?

You will need to do two things:
Create Styles for your DataGridColumnHeaders
Apply the Header Style while the columns are auto-generating using an 'AutoGeneratingColumn' event handler.
Here's a working example:
Example Output: ('FirstName' and 'LastName' headers look different from 'Age')

Implementing Virtual File Drop in WPF using VirtualFileDataObject

I'm using the solution from this project: http://dlaa.me/blog/post/9913083#comment-2930777923
I wanted to make my WPF program able to process the virtual file dropped into it, but I'm stuck with reading the relevant data from the MemoryStream, what I receive from DragEventArgs e.Data.GetData().
I've read many posts. the closest were:
https://blogs.msdn.microsoft.com/delay/2009/11/04/creating-something-from-nothing-asynchronously-developer-friendly-virtual-file-implementation-for-net-improved/#10040454
https://www.codeproject.com/Articles/23139/Transferring-Virtual-Files-to-Windows-Explorer-in
and the above mentioned, of course
and many others to drag&drop local files, that obviously don't help
But all of them handle the from-my-app-to-filesystem case only.
Without any fancy mvvm stuff...
where I don't get any further is the

Show Mahapps.ProgressRing when loading data in WPF

I'm populating a DataGrid with sorting and grouping in WPF and I want to implement a progress indicator to the user for them to know that the current query is still running in the background. I'm trying to use the ProgressRing of Mahapps but i don't know how do I implement it. Below is my code.
Code Behind

You can use XAML in Silverlight
Questions on stackoverflow about silverlight: https://stackoverflow.com/search?q=siverlight
The structure is equals to WPF but some features are different between they

If you want to run native WPF applications you would need to consider creating a XBAP application like Glen said. Note that XBAP application support in modern day browsers is rare to find today and can be limited.
If you want to use XAML controls/files in your ASP.NET website, you will need to write a Silverlight application first, and then add the control to your website. Note that some browsers are even discontinuing support for Silverlight applications
Reference materials

The best way to use XAML in a web application is to use Silverlight. Using Silverlight is not a great idea for any project at this point.
Extended support for Silverlight ends 10/12/2021, which makes it seem like Silverlight should be around for ahwile, right? Wrong. In order to run a Silverlight application on the web, you'll need a browser that supports it. Chrome won't support Silverlight after September. Firefox is making users jump through hoops if they want to run the Silverlight plugin. And under Windows 10, the user has to be running IE11, Edge won't run Silverlight apps.
XAML on the web is dead.

How to play BackgroundCapableMedia with PlayTo on Windows 8?

I have in StandardStyles.xaml next code:
<Style x:Key="RootFrameStyle" TargetType="Frame">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Frame">
<Grid>
<MediaElement x:Name="MediaPlayer" AudioCategory="BackgroundCapableMedia" />
<ContentPresenter />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
and in App.Xaml.cs next code in OnLaunched:
...
rootFrame.Style = Resources["RootFrameStyle"] as Style;
...
in MainPage.xaml.cs code:
PlayToManager playToManager = null;
CoreDispatcher dispatcher = null;
private void LayoutAwarePage_Loaded_1(object sender, RoutedEventArgs e)
{
if (App.Player == null)
{
var rootGrid = VisualTreeHelper.GetChild(Window.Current.Content, 0);
App.Player = (MediaElement)VisualTreeHelper.GetChild(rootGrid, 0);
App.Player.Source = new Uri("http://myserverlink.com/mymp3file.mp3");
App.Player.Play();
}
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
dispatcher = Window.Current.CoreWindow.Dispatcher;
playToManager = PlayToManager.GetForCurrentView();
playToManager.SourceRequested += playToManager_SourceRequested;
}
void playToManager_SourceRequested(PlayToManager sender, PlayToSourceRequestedEventArgs args)
{
var deferral = args.SourceRequest.GetDeferral();
var handler = dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
{
args.SourceRequest.SetSource(App.Player.PlayToSource);
deferral.Complete();
});
}
And if I click devices in windows 8, in the list of devices for PlayTo no devices.
And if one is to add a MediaElement in MainPage.xaml, the devices in the list.
But I need to MediaElement was of Style File, what would you navigate to another page did not stop play music. What to do?
