I am trying to write a C# program in wpf that retrieves the content of a web page.

The first thing I tried was to try the WebRequest and WebResponse classes. This did not provide the actual displayed content. WebResponse reveils the HTML code that is sent to the browser. But I discovered that, while the page is being loaded by the browser, javascript can change what content is finally displayed in the browser.

So I decided to use the WebBrowser class.

Immediately I found that there are two WebBrowser classes. Thee is the one that is documented for WinForms and there is another that is documented for WPF. I need to understand the one documented for WPF. What I think I neeed to know what to do is to retrieve code after the "LoadCompleted" method is caused. But I do not know how to this and I cannot find any example demonstrating how this is done.

data appears on some computers but not others

Not sure what info to write, but wanted to get this thread started. I have a project with 2 UI developers. I run some of the testing and builds on my machine.

The UI guys can pull data for some grids and it displays just fine. No issues. I will get latest, compile and run the app. I see the data everywhere except for 3 particular grids. All grids are coded up the same way-same design pattern. Also, we use mvvm style.

The UI developers compiled and ran on 5 different machines (VMs, physcials win7 and win8) The data in the grid always appears.

I am running win7 on a VM. I have the same version of telerik controls installed.

any ideas?

thanks

How to Enable/Disable the TrackBall Behavior

Hi,

I'm version 2012.3.1017.40 and trying to enabled the TrackBar Behavior on a double-click on the chart's data area and then disable it with another double click. I keep getting an exception when I try to disable it. I'm wondering if this is a bug with the control, or is it the way I'm trying to disable it?

Here is how I'm trying to Enable/Disable the TrackBall behavior:

private void radCartesianChart1_MouseDoubleClick(object sender, MouseButtonEventArgs e)

{

int index = -1;

for (int i = 0; i < radCartesianChart1.Behaviors.Count; i++)

{

if (radCartesianChart1.Behaviors[i] is ChartTrackBallBehavior)

{

index = i;

break;

}

var mousePosition = e.GetPosition(this);

Telerik.Charting.DataTuple tuple = radCartesianChart1.ConvertPointToData(mousePosition);

//make sure the double-click occurred in the chart data area

if (Convert.ToSingle(tuple.FirstlValue) > 0 && Convert.ToSingle(tuple.SecondValue) > 0)

{

if (_ShowTrackBall == false)

{

//create the TrackBallBehavior and add

if (index == -1)

{

ChartTrackBallBehavior tb = new ChartTrackBallBehavior();

tb.ShowIntersectionPoints = true;

tb.ShowTrackInfo = true;

radCartesianChart1.Behaviors.Add(tb);

_ShowTrackBall = true;

}

else

{

if (index != -1)

{

ChartTrackBallBehavior tb = radCartesianChart1.Behaviors[index] as ChartTrackBallBehavior;

radCartesianChart1.Behaviors.Remove(tb);

_ShowTrackBall = false;

}

It throws an System.ArgumentNullException, {"Value cannot be null.\r\nParameter name: key"}, when I try to disable it with the following StackTrace:

Listbox DragDrop inside TileView

Please find the sample project here

The sample application is divided into two parts:

The bottom part is similar to the RadListBox drag-n-drop demo with 4 elements:

RadListBox bound to ObservableCollection<Country> CountryList
RadListBox bound to ObservableCollection<Country> GroupA
RadListBox bound to ObservableCollection<City> GroupD
WPF ListBox bound to ObservableCollection<Country> GroupA, AllowDrop unset

The Drag-n-Drop behaviour is as expected, I can drag n drop between 1&2, but not to 3 or 4, it worked very well.

The top part is the identical setup, except it is contained within a RadTileView, and there are a few unexpected behaviours:

Cursor no longer change to Cursors.No when drag over list 3 & 4
When dropped on list 3, nothing happens, this is good. But when dropped on list 4 or anywhere on the tileview that's not a RadListBox, the item is removed from the drag source, and not added to anywhere.

So how do I fix these two issues?

Binding

I am trying to draw some polygons and within the polygons I want to put information about the polygon.  



Eventually I will have multiple textblocks in the stackpanel.  I don't understand how to bind to my additional data.  I am using MVVM and my polygon binds good to Points. 



If I change the textblock to

<TextBlock Text="Test" /> the textblock will show in the polygon with Test. Output does not show any binding issues, it just doesn't work.

telerik:RadMap x:Name="radMap" Center="49.002049,-101.367682" ZoomLevel="8" Width="1350" Height="700">

<telerik:InformationLayer x:Name="infoLayer" ItemsSource="{Binding Model.Items}">

Tooltip on SplineSeriesDefinition doesn't work

Hi everyone,
I'm desperately trying to show a tooltip on a SplineSeriesDefinition, but it doesn't work. I've read the most of the related post but unluckily, I wasn't able to fix my problem. I have a DataSeries populated with several DataPoint. I tried to set the tooltip on every DataPoint, on the SplineSeriesDefinition and even on the SeriesMapping unsuccessfully. All that I want is a tooltip when mouse is over the curve. Please, I urgently need to fix this problem. Might someone help me, please?
Below there's the definition of the RadChart in my XAML code, and a piece of code of my CS file:

<telerik:RadChart Name="radChartCurva" VerticalContentAlignment="Stretch" HorizontalContentAlignment="Left" Grid.Row="0" />

foreach (DatosGrafica graf in media)
{
DataPoint dp = new DataPoint(graf.valorX, graf.ValorPunto);
dp.Tooltip = graf.ValorPunto.ToString();
seriesCurva.Add(dp);
seriesMedia.Add(new DataPoint(graf.valorX, graf.Media));
}
seriesCurva.LegendLabel = StringResources.curve;
seriesMedia.LegendLabel = StringResources.average;

SplineSeriesDefinition serieDef = new SplineSeriesDefinition();
SplineSeriesDefinition serieDef2 = new SplineSeriesDefinition();
serieDef.ShowItemLabels = false;
serieDef.ShowPointMarks = false;
serieDef.ShowItemToolTips = true;
serieDef2.ShowItemLabels = false;
serieDef2.ShowPointMarks = false;
serieDef2.ShowItemToolTips = true;

seriesCurva.Definition = serieDef;
seriesMedia.Definition = serieDef2;

SeriesMapping sm = new SeriesMapping();
sm.SeriesDefinition = serieDef;
sm.ItemMappings.Add(new ItemMapping("XValue",DataPointMember.XValue));
sm.ItemMappings.Add(new ItemMapping("YValue", DataPointMember.YValue));
this.radChartCurva.SeriesMappings.Add(sm);
this.radChartCurva.DefaultView.ChartArea.DataSeries.Add(seriesMedia);
this.radChartCurva.DefaultView.ChartArea.DataSeries.Add(seriesCurva);

What's wrong with my code?

Thanks in advance guys :-)
