Printing problems

Hi,

I have problems to use print-method in RadRichTextBox control. E.g when I dynamically load RadRichTextBox to the visual tree and then set the document. This throws an null exception when I call the Print-method.

RadRichTextBox textBox = new RadRichTextBox();

grid.Children.Add(textBox);

textBox.ApplyTemplate();

textBox.UpdateEditorLayout();

textBox.Document = this.CreateDocument();

textBox.Print("MyDoc", PrintMode.Native); // It crash in here!

CreateDocument returns a valid document, I have tested it by loading it to radRichtextbox without printing.

Hopefully you can see directly what is wrong in my code... if you can provide sample project, that would also help.

I'm using WPF version of Telerik controls (ver. 2011.2.712.40)

Regards,
Auvo

[Solved] Removing words from dictionary (cuss words, etc)

Hi,

We want to remove certain words from the dictionary (any words that would be embarrassing for customers... including some that may be proper anatomy words, but wouldn't be used in our application). Is the best way to do this to download the dictionary from http://www.telerik.com/community/forums/aspnet-ajax/spell/147971-radspell-dictionaries.aspx#576503, and edit the dictionary? If not, what is the best way to go about that?

If we are going to edit the dictionary, can we add our own custom words directly to it rather than creating an IWordCustomDictionary? If that's okay, what do the last two items on a line in a TDF file represent? For example, what do the JNNL and KNNL represent in the following line:

genuinely:JNNL:KNNL

Thanks!

"Search as you type" bug?

I'm following the GridView demo called "Search as you type". I am using the exact code from the example (CustomFilterBehavior.cs and CustomFilterDescriptor.cs). I have found that the filter does not work if your data has a column of doubles all with a value of 0. If the doubles are given values > 0 then suddenly the filtering works but at 0 no filtering is applied. Very odd.

Can you verify this problem and suggest a work around, possibly a change to CustomFilterDescriptor.cs?

thanks.

Index of visible selected row

I'm working with a gridview that has a CellTemplate with a CheckBox column and I'm able to set the IsEnabled value using the following code.

    IList<CheckBox> cbks = myGridView.ChildrenOfType<CheckBox>().ToList<CheckBox>();
    MyObject selectedProject = myGridView.SelectedItem as MyObject;
    int SelectedIndex = myGridView.Items.IndexOf(selectedProject);
    cbks[SelectedIndex].IsEnabled = True;
 
 
This works great, but except ChildrenOfType<>() only provides the rows for visible rows. I can not set EnableRowVirtualization to False.

 

How do I get the index of the visible row that is within the List of checkboxes (chks)?

 
Thanks in advance.

Custom sorting

For the sake of the others, please update your custom sorting guide to include IsCustomSortingEnabled on the columns. I spent almost a day figuring out why the sorting didn't work anymore (It sorts once but the NewSortingState property doesn't stick). This is very frustrating and is nowhere mentioned as a requirement.

Text Wrap and Search as you type

Hello,

We are using the search as you type feature described in your blog:

http://blogs.telerik.com/stefandobrev/posts/10-01-18/highlighting-inline-search-for-radgridview-for-silverlight.aspx

However, we noticed that once the HighlightingTextBlock was applied to the cell, the TextWrapping attribute was lost. Can you please provide an example of the correct way to support TextWrapping with the search feature? Thanks for any help.

MarkedZone or CustomLine display level

I have a chart with 11 series: 9 range series that together make topo map of standard deviations from the mean; 1 scatter series above the topo map of their standard deviations from the mean; 1 annotation series with MarkedZones in gray for every X axis value (sequential integers) that has been parameterized (have manually adjusted variance used in estimation) and with a red CustomLine to mark each X axis value with a 0 trend estimation. My problem is that I would like to have the annotations (MarkedZones and CustomLines) display with transparency over the 9 range series but under the scatter series. By default, everything overlays the annotations and so I have to make my 9 range series transparent to see the annotations. This makes the range series appear washed out. I can't seem to find a way to set a level of the annotations to display at the 10th level rather than the 1st. All eamples and forum entries show annotations as alway in the background of the chart area with all series over them, so I am dreaming in technicolor here. Do any of you generous and more experience folks have any suggestions.

Note I also observed that my scatter series is at the right level, but if I try to set the CollectionIndex it does not appear. I guess I am lucky it is were I need it.

Regards

Line Series & Negative Values

When I plot a line series with negative values, the negative points do not get plotted. XAML is below.

<telerik:RadCartesianChart Palette="Metro" HorizontalAlignment="Stretch" >

<telerik:LineSeries CategoryBinding="X" ValueBinding="Y" ItemsSource="{Binding Data}" />

<telerik:RadCartesianChart.HorizontalAxis>

<telerik:DateTimeContinuousAxis ShowLabels="False" />

</telerik:RadCartesianChart.HorizontalAxis>

<telerik:RadCartesianChart.VerticalAxis>

<telerik:LinearAxis ShowLabels="False" />

</telerik:RadCartesianChart.VerticalAxis>

</telerik:RadCartesianChart>

For one of my data series, there are no positive Y values, which results in a blank chart.

Problem with the auto setting of ranges I suspect?

Can any one at Telerik suggest a usable workaround?
