Is RaWindow a good candidate to function as a child window that cannot be dragged outside the confines of its parent's boundaries?

Similar to shadowbox-type functionality on websites when user input is required and parent is locked?  We'd like the user to still be able to drag/resize/minimize/etc the parent while the child window is controlling it.

hello,

i am trying to set up a custom range on my y axis as our 'date' values are custom generated and do not work in the same way as normal dates or numeric values.

we have a situation where the chart would run along variable time levels, ie sometimes weeks, sometimes months, quarters, etc. the chart needs to plot these time members across the Y axis of a horizontal 2D Bar chart and display the values as such:

M201010       M201011       M201012     M201101 etc..

what we did to overcome the fact that we need a numeric value for the axis was to use only the numeric section of the chart and then set a min and max value (since we know the start and end date for the chart) but this works only as long as the values are for the same year, in this example 2010.

if the periods span over 2 years, ie from 2010 to 2011, the series stretches from M201012 all the way to M201099 before getting on to 2011, because it increments by one of course.

the chart is set up in the xaml as follows:



is there a way to get around this?

thanks,
Nemanja

I show a message box in cellvalidating event to show the error message as a Messagebox..

It usually work ok, but if i use the TAB key to move out of the field, the event fire twice (so the message box show twice... )

Hi There,
I am using the RadPane and RadDocumentPane in my application, can you please tell me what is difference between them ?

Regards,
Srinivas.

Hi, I am attempting to add a custom line or custom grid line annotation to my RadChart. I need to make the line dashed, but do so completely in c#, not using any XAML styles. How would I do this?

Also, how would I add my annotation to my legend, completely in code. I saw the example:
http://www.telerik.com/help/wpf/radchart-how-to-add-annotations-in-chart-legend.html, but that uses XAML styles, and I can't do that.

How would I ensure that the annotation appears in front of the data series? I.E. the bars for the bar chart are behind the annotation.

And finally, how would I add labels to annotations, again, in c# code only.

This is based on the most recent build we have (downloaded this morning, RadControls_for_WPF_2011_3_1116_Dev_hotfix)

 

When we import a  file in docx format, and do a MailMerge() call, the fields merging appears to work perfectly, except that the style (or ‘format’ in MS Word parlance) is not maintained. Whether it’s bold, underlined, different font, different colour, it doesn’t matter, the text that is merged into that field always goes in with what appears to be the default RadDocument/RichTextDocument format (Verdana, 12 pt).

I’ve not been able to find any properties or anything that seem to indicate that merged values will override the styles/formats of the merge fields they’re replacing. It doesn’t appear as if it’s respecting the “Preserve formatting during updates” setting from MS Word

This is the code being used:

 

private RadDocument MergeDataFieldsWithDocument(RadDocument radDocument)

        {

 

            var mergeFieldsAndValues = DeriveValuesToMergeWithDocumentFields();

 

            radDocument.MailMergeDataSource.ItemsSource = mergeFieldsAndValues;

            return radDocument.MailMerge(false);

        }

 

        private static List<object> DeriveValuesToMergeWithDocumentFields()

        {

            return new List<object>

                       {

                           new

                               {

                                  DATE_TODAY = "test"

                               }

                       };

        }

How can we make it so that the merge fields use the correct format?

Thanks,

Brock

Hi, I use the following code to overwrite the FilteringControl

Then, in the code behind of the view,


After recompile and run the application, the filter changes to Contains.

However, when the filter is opened first time, the text boxes below the filter dropdowns are not shown.

When the filter window is opended the second time, the text boxes will appear.

Anything I can do to fix this?

Thanks

Hello,

I'm using internal build 2012.3.1017.40 and it seems the GridView is using the wrong locale (en-US instead of de-DE) when DataFormatString is applied to cells. Currency values are formatted as "$100.00" instead of "100,00 €". Is there a new configuration I have to set up or is it an issue with this build? I need to use the internal build because I'm using the WPF ReportViewer as well and there is that mean printing bug in the main release.

Kind regards
Markus
