Hi,

I was wondering if the WPF control suite had anything to support notification bars? Similar to those made popular by JavaScript in the last couple of years. http://www.hellobar.com/solo/ is an example of what I'm talking about.

Thanks Ed.

Performance on removing multiple AnnotationRanges

Hi

I have a specific requirement that involves removing a number of annotation ranges at a time. The only way I can see of doing this is via the Document "Delete" commands to remove them one at a time (some of these are read only ranges, so I can't just create a selection across them all and Delete the selection).

I've stepped through the code and the process of removing these individually called "EnsureDocumentArrangedAndMeasured" after each one is removed, which for a large file absolutely kills the performance. Is there any way I can improve this?

Thanks

Charlie

Expander Mouse Clicks

I have an Expander that I set IsEnabled="False", but I want to know if user clicks on it so that I can display a message.

Please point me to an example on how to capture that mouse click (MouseDown for example)?

Thanks

How to add bars to stacked chart programmatically

I need to do the roughly the same thing as described here:
http://www.telerik.com/community/forums/wpf/chart/group-by-date-and-stack-by-itemtype.aspx

but with some important differences:
I am polling a device for data. I add rows to my data source and bars to my chart in the elapsed event of a timer. So I need to update my chart in real time.
My data source looks like this:
MyClass
{
DateTime PeriodEnd
string Source
int Value
}
Where PeriodEnd is the value for the X axis, Source is how the data is grouped within each PeriodEnd, and value is the quantity to be plotted for each group (Source).

I dont know in advace what the values for Source will be or how many unique values there will be. I just need to take all the rows for a given PeriodEnd, and chart the value for each Source.

Can you kindly point me to an example that will show me how to do this? This is my first project with Telerik - sorry I'm an newbie.

Errors since Q3 2012 SP1

I have the following RadGridView defined (using .NET 4.5):

<telerik:RadGridView

ScrollMode="Deferred"

ColumnWidth="Auto"

ActionOnLostFocus="None"

AutoExpandGroups="False"

SelectionMode="Extended"

AutoGenerateColumns="False"

EditTriggers="F2"

IsSynchronizedWithCurrentItem="True"

SelectionUnit="Mixed"

ClipboardPasteMode="Default,AllSelectedCells,OverwriteWithEmptyValues"

>

<telerik:RadGridView.ChildTableDefinitions>

<telerik:GridViewTableDefinition/>

</telerik:RadGridView.ChildTableDefinitions>

<telerik:RadGridView.HierarchyChildTemplate>

<DataTemplate>

...

</DataTemplate>

</telerik:RadGridView.HierarchyChildTemplate>

</telerik:RadGridView>

As of Q3 2012 SP1, I get the following two errors:

The local property "IsSynchronizedWithCurrentItem" can only be applied to types that are derived from "DataControl".
The specified value cannot be assigned to the collection. The following type was expected: "TableDefinition".

Any suggestions on how to resolve this?

Thank you.

Create a Win8 touch button

Hi,

I need to add a button to my WPF application that is touch enabled. I'd like to use either a forward or home button that looks like a WinRT / Win8 touch button. I've applied the Win8 touch theme to my application but I don't know where to go from here.

Inserting image in column depending on checkbox check state in other column

Hi everyone,

I've just started testing out the Telerik components for WPF in search of a component bundle to purchase for
our development projects and have started out testing the GridView for WPF. A wonderful piece of work.

However, I have a question. How do I insert an image in a column based on the value of a checkbox that
resides in another column.

I.e, if the checkbox check state on column 0 is true I'd like to insert an image of a green tick icon (which I have as a .png file)
into column 1, etc.

Is there a simple way to achieve this?

I'm coming from Windows Forms development which makes all this XAML stuff a bit new to me so sorry for the newbie question.
