Hi Team,

I was going through your documnet described in this blog post here. (Export to PDF in Help for Rad Chart)

Here when a chart we need to export is not in visual tree, we create a new RadChart and add the series mapping to it and export it.
But in my case I'm not using the DefaultView of RadChart, because I need to have a grid inside my chart area. So the modified RadChart I created in Xaml and using the same.
Now what I'm trying to do is I'm assigning the DataSeries to the chart I have in xaml (not creating a new one as in your example), and creating my chart. Now when I try to export it using ExportToImage, it throws an exception of null reference.

Is it not possible to export the chart which I have an updated view in xaml, when its not visible in the UI, by assigning the DataSeries as explained in your example (ex: not visible in visual tree)?

Please reply soon.

Thanks.

StackedBar in codebehind for dynamic columns

I've been struggling to create a stacked bar chart with that will display the following data:

I realize that since the columns (years) are dynamic that i must create the chart in codebehind. However, I've been lost with trying to figure out how to loop through the data (in the form of a datatable, that looks exactly like the grid in the screenshot above) and what item mappings and/or groupsettings to specifiy. Any help with figuring this out would be most appreciated! Thanks

RadGridView and DateTimeOffset

Hi,

I have a user control with RadGridView bound to the database table.

The table has a DateTimeOffset column.

It seems that the filter doesnt function properly with this DateTimeOffset datatype (the Date time picker in the filter window of the Grid View Column filter doesnt show up, and the options for filtering is constricted to only isEqualTo and IsNotEqualTo. Other options are not available).

I tried binding the columns with DateTime datatype where ever I could bind the grid to a Object (or Property) which is in turn bound to the database column.

But, where ever I need a direct binding to the database, I am not able to do this.

Can you please suggest any alternate solution?

Thanks and regards

RadWindow.Prompt not displaying when providing WindowClosedEvent

Hello,
The following code displays a prompt as expected only when I don't provide the event handler :

var DialogParam = new DialogParameters

{

Content = new TextBlock()

{

Text = "..."

},

Header = new TextBlock()

{

Text="",

}

};

RadWindow.Prompt(DialogParam);

RadWindow.Prompt(DialogParam, ActionOnClose);

In the second case It displays "Telerik.Windows.Controls.DialogParameters " instead of "..." :-/

Crosshairs in RadChart

Hello,

In one of our projects we have the need of adding crosshairs (vertical line + horizontal line that marks the location of a point, displaying the X coordinate and Y coordinate) to a radchart. I've seen that this functionality is not available by now. However, I found some examples in the Internet about how to make this possible in Silverlight using the toolkit controls (see http://www.scottlogic.co.uk/blog/colin/2009/02/adding-a-location-crosshair-to-silverlight-charts/) by modifying the control template.

My question is if there is any way to add this functionality by editing the radchart template or similar... any examples would be highly appreciated as this is the first project that we carry on WPF and Telerik Controls :-).

Hope you can help us !!!

Export to PDF, non visual chart

Hi Team,
I'm able to generate the chart using the help provided for generating the chart when not present in visual tree.

Bar chart export is working fine, but there are some problems with the Sand Chart.
