I just download telerik for WPF.

I use ChartView and i would like to bind String on Horizontal Axis and sort it on an other binding.

Is it possible ?

            <chart:RadCartesianChart Name="BarChart" Palette="Metro" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" >
                <chart:RadCartesianChart.HorizontalAxis>
                    <chartView:CategoricalAxis Title="HorizontalAxis" LabelFitMode="MultiLine" LabelStyle="{StaticResource AxisLabelStyle}" >
                        <chartView:CategoricalAxis.TitleTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding StepPosition}" Margin="0,6,0,10" Style="{StaticResource AxisTitleStyle}" />
                            </DataTemplate>
                        </chartView:CategoricalAxis.TitleTemplate>
                    </chartView:CategoricalAxis>
                </chart:RadCartesianChart.HorizontalAxis>
 
                <chart:RadCartesianChart.VerticalAxis>
                    <chartView:LinearAxis  Title="VerticalAxis" LabelStyle="{StaticResource AxisLabelStyle}" >
                        <chartView:LinearAxis.TitleTemplate>
                            <DataTemplate>
                                <TextBlock Text="{Binding}" Margin="0,6,0,10" Style="{StaticResource AxisTitleStyle}" />
                            </DataTemplate>
                        </chartView:LinearAxis.TitleTemplate>
                    </chartView:LinearAxis>
                </chart:RadCartesianChart.VerticalAxis>
 
                <chartView:BarSeries ItemsSource="{Binding Inventory.View}" ValueBinding="CountBatch" CategoryBinding="StepPosition"

Is it possible to make the Grid create a GroupDescriptor instead of a ColumnGroupDescriptor? I modified the header of the grid columns to have buttons that perform actions when the user clicks on them. Now when the user groups by a column I can see the buttons on the grouppanel as well.

Hello,

I am seeing a weird behaviour with the TreeListView where it appears that it is creating new items upon calling ExpandAll().  I am curious as to whether this is a known issue, or whether anyone else has seen this too.

I bind my TreeListView to a list that has a total of 87,954 rows.  There are 18,493 top-level rows and the remainder are children (at various depths).  I have exposed a button on the UI that simply calls ExpandAll() on the TreelistView.  After this is clicked, the TreeListView displays a varying numbers of rows, all of which are greater than 87,954.  Each time I launch the app and click the "expand all" button, I get different numbers of rows.  I have seen 88,228, 88,232, 87,985 etc. - each of which is larger than the 87,954 as expected.  I have confirmed that my bound collection has not changed, so I am lead to believe that somehow more items are being created during the expansion process.  I have also noticed that if I try to scroll to the bottom of the TreeListView, it chokes and stops responding for some time before it will allow me to scroll to the bottom.

All these issues make me think that I am seeing a bug in the ExpandAll functionality.  Can anyone confirm?  (I am using the Q3, 2011 build.  I will try the latest build shortly, but I am not at a point in our release where updating is possible.)

Thanks,
Mark

The Telerik Work Item Manager application uses Log4Net as its logging component. It defines a configuration section for Log4Net inside the app.config file. The problem I'm having is, we use Log4Net extensively here at this company, and we've already defined Log4Net blocks inside our machine.config files. When Work Item Manager starts up, it sees these conflicting configuration blocks and throws an exception.

Can someone explain how I can work around this to start up Work Item Manager? Perhaps there's a way to disable Log4Net for WIM so it doesn't initialize those components? It seems silly that just because I have Log4Net preconfigured on my machine that I'm not allowed to use this application.

Hi,

I would like to switch between Value and the Percent representation on the chart on the basis of the selection of radio button.
I am sending the data in the form of values in the data set and would like to use some type of content format to achieve this functionality. So that i dont have to code extra for calculating the percentage and sending that to the data set of the RadChart instead.

I am attaching the user interface i have achieved and also the changes for the UI i would like to achieve.

Thanks in advance.

I am trying out RadControls for WPF Q1 2012.

When setting up line series for a cartesian chart I set the vertical axis in each series. Some of the series can use the same vertical axis so I assign the same linear axis for the vertical axis in each of those series.
 
Is this the correct way to share a vertical axis between series?

I wonder since if I call Clear() on the chart series after setting things up in this way I get a null reference exception as follows:

System.NullReferenceException was caught
  Message=Object reference not set to an instance of an object.

The exception doesn't happen if each series has a unique axis.

If this is the correct way of sharing a vertical axis between series then how do I clear the series without getting an exception?

I have developed a custom control for multiple selection in Rad Combobox. Now i want to show the selected items as comma separated string. Can i manipulate the display member of rad combo box at runtime?

Hi Telerik:
How can I hide the entire group header column (the bottom level only) as pointed in the screenshot below? I have attached xaml for your reference.

Thanks,

Hi All
How can I get font size from SelectionMiniToolBar in pixels instead of points.
Thanks

Part 1: Date format in GridViewDataColumn:
I have a need to display a DateTime in a column with the following format: "MMM dd yyyy h:mm:ss tt". How would I go about doing that? Using the DataFormatString dependency property seemed like the logical choice, but did nothing.


Part 2: How do I filter by date?
On the Telerik webpage under the heading "Filtering and Excel-like Filtering", there is a date time filter. How do I enable that for a GridViewDataColumn that has a DateTime as a backing property type? I've tried all sorts of things, and this is what I'm currently using, but it does nothing - I only am able to use the standard string filter.



Part 3: How do I show empty cells for DateTime.Min values?
I also have the need to show an empty cell if the backing value is DateTime.Min. How would I accomplish that?
