Can the transition control be used in an MDI type scenario?

We have an application with multiple views, but each of them should only be showed inside the main view.

Is this advisable or is it a bad idea?

Thanks,

Hello,

First I would like to say that I'm very impressed with level of customization you allow and the easy to understand and quite comprehensive online documentation.

I don't know whether to post this question under 'Chart' or 'ChartView' yet I attend to use the one that will resolve my current issue.

Platform
I'm developing for a touch environment (wpf pixelsense sdk 2).  

My goal
When a user touches anywhere on a graph (stacked area series) - show him information about the data point he touched.

In a technical aspect:
1. Use touch down/click/manipulation events to recieve a data point 
2. Alternative solution - to be able to get the item (data point) in a given position. This way I will be able to trap touch events manually.

Limitations
I cannot use any mouse events, only touch events.

What I've tried:

experiment  1
1. Add 'ChartTrackBallBehavior' to my chart
2. Register to 'TrackInfoUpdated' event
3. Use 'e.Context.ClosestDataPoint' to get data point of current position

Result
Since I'm using touch device I need this event to be triggered when touching (touchdown event) but it doesn't. 
I saw a possible workaround but it seems to be relevant only to wp8 controls and not to wpf (link)

experiment 2
1. Register to 'radChart.DefaultView.ChartArea.ItemClick' event.
2 Use the event arguments which include information on the clicked item.


Result
It works only if I uses the mouse, when using touch the event is never beng promoted (might be because the chart is hosted inside scatterviewitem) . I have tried to bypass this issue without success.

Any workaround exists on current version will be much helpful.

Sincerely,
Guy

Hi, i need to print the RadMap on a Paper with format A0 (big dimension), it's possibile ?
Actually for print the map use the code on the post:http://www.telerik.com/community/forums/wpf/map/print-copy.aspx
it's work but the dimension of the map is the dimension on the screen resolution.

Thanks

Hello, I am new with Telerik controls, but it's making my applications looks much better.
But I have a problem, My application has a RadTabControl with 4 RadTabItem, and the RadTabItems contains a grid with a RadGridView with an ItemsSource, this is the one that is wrong:


I have ser my RadGridView "gridStatus" Height, Width and ColumnWidth to Auto, but in runtime I get an extra column and the content does not fit the width of the RadGridView ( I attach a screen print)

I have tried to set Height and Width in Page1.xaml.cs but I can´t set it to Auto, because the value has to be a double.

But the weirdest thing is that I have another RadGridView that works fine, I copied the code from this to the other, and removed a column that I didn't need, and it was the same, the properties are set to Auto, but I have an "extra column".

Hope you can help me because I have no idea of what to to.
Thanks!

Hi,

I am trying to add a new row to RadGridView. I can add new row, BUT It doesn't allow me to enter more than 4letters in the new row. Could you check this and let me know what went wrong?

Thank you,

Hi,
In application we are using the Grid where one of the column has "DateTime" data type.
I am using RadDataFilter to filter the column values, for this particular column when data filter comes up it comes with the DateTimePicker.
Inside this DateTimePicker if user types "Today" it converts the string into Today's DateTime
I want to stop this behavior so that if user types "Today" it will consider it as a string and
should not convert into corresponding DateTime value.
How can i achieve this?

Hi all,

I am following the example given in WPF demo -> Controls -> Visualization -> Chart -> Performance -> Live Data, in particular, I am looking at this line of code: 
In my data set, I am updating over 20 line series every second, and resetting the view data with this.Data = null and this.Data = this.cpuData seems to be incredibly slow. Is there a better way to update the chart with live data?

Thanks,
Jin

Hello,
I tried to use RadColorPicker ContentTemplate property (example in Telerik manuals). But I get exception:
The attachable propert 'ContentTemplate' was not found in type 'RadColorPicker'.


What happened?

version: RadControls for WPF Q1 2012 SP1

I'm exporting my radgrid to Excel, that part is working great.  What I'm having trouble with is one of the columns in the gridview is a listbox, so in my export, I want to export the list.  I do have that working correctly, I'm getting all items in the list.  Where I'm stuck is I want each item in the list to be on a different line in the Excel cell, so when it exports and I open Excel I want to see

Item A
Item B
Item C

what I currently get is Item A Item B Item C

Below is my code, is there something obvious I'm missing to accomplish this?

if

 

 

(e.Element == ExportElement.Cell)

 

{

 

 

if (e.Value is SurveyDetail)

 

{

 

 

SurveyDetail surveyDetail = (SurveyDetail)e.Value;

 

 

 

if (e.Context is Telerik.Windows.Controls.GridViewDataColumn)

 

{

Telerik.Windows.Controls.

 

GridViewDataColumn dc = (Telerik.Windows.Controls.GridViewDataColumn)e.Context;

 

 

 

if (dc.Name == "dcCPUJobCode")

 

{

 

 

StringBuilder sb = new StringBuilder();

 

 

 

foreach (CPUJobCode cpuJobCode in surveyDetail.SurveyJobCode.CPUJobCodes)

 

{

sb.Append(

 

string.Format("{0} {1} \n", cpuJobCode.JobCode, cpuJobCode.JobTitle));

 

}

e.Value = sb.ToString();

}

}

}

}

Hi, I am currently working over the chart control which should fulfill the following requirements:

• represent live linear charts (like a processor load chart)
• provide multiple y-axis (to represent charts of boolean, integer and double variables on the same x-axis)
• provide panning by x-axis ability

I checked if your RadChartView control was able to deal with this task and fell in trouble with several issues. I hope that reasons for such a behavior come from my lack of understanding how charting should be implemented, so we will be able to rely on your control if only we would have those issues fixed. Instead of attaching the whole project, I will try to provide enough information for you in the code snippets.

I need to show from 1 to 10 parameters of different types.

When each parameter is updated i add new value in the corresponding array this way: 

ParameterInfo._log.Add(val, DateTime.Now);

The first problem is

'How can I provide simple x-axis panning capabilities for the live chart?'

I have a timer which updates the chart each 500 milliseconds. It basically fixes the Maximum and Minimum properties of the x-axis:

In this way the auto-pan to the last moment works alright but there's no possibility to pan the chart. 

It's obvious that if I want to provide the panning to the very initial moment when the chart was shown, I shall leave 

chart.HorizontalAxis.Minimum == initialDateTime;

I see two possibilities to fix this issue:

1. Use the external scrollbar and bind it to HorizontalAxis.Minimum and HorizontalAxis.Minimum properties. Activate user-driven panning when the scrollbar changes its value, switch back to auto-panning when, for example, user sets the maximum value on the scrollbar. Unfortunately this won't look good enough if I will use the external scrollbar. Is it possible to customize the behavior of the internal scrollbar to satisfy our needs?
2. Every time the chart should be updated (500 milliseconds in my case) leave all the parameters unchanged except the zoom scale. Theoretically it's possible to calculate the appropriate zoom value so the absolute size of the visible segment on the x-scale would be constant. However I couldn't find available property via which I could change the zoom scale dynamically from the code behind. Is there any possibility?

The second problem is

'How much points should i add to the data source? How much points is it able to carry?'

At first I tried to add the values every time the timer event is figured (i.e. each 500 milliseconds) However it turned out to be a bad idea. The chart started to go slower and almost stopped with the time. It had about 5000 data points just for 1 minute. I suppose that either there shouldn't be very much points in the data source or I should dynamically filter only the visible segment of a big array. Do you see the latter way convenient enough?

So I turned to the other option, I added new data points to the appropriate series only when their values change. Unsurprisingly, the result looked like a saw (attached file telerik letter - zig-zag trackball.gif)

So I had to add two values when the new value arrives and move the second one further to prolongate the horizontal segment until the next change:

I want you to know if this is a convenient way because it leads to the problem with the TrackBallInfo. Because there are no data points, in between the moments of the value change, the TrackBallInfo snaps to the closest data point instead of displaying the actual value under the mouse pointer. This is not desired (look at the attachment telerik letter - trackball glitch.gif) 

I also have troubles with the dynamical setting of the bunch of y-axes in the code behind, but I didn't try enough by myself yet because it's crucial to know if Telerik's solution is able to deal with just the issues described here.

Thank you,

Andrey
