RowStyleSelector with TreeListViewRow Control Template to display different row types

I am trying to supply different TreeListViewRow templates using a RowStyleSelector to show certain types of rows (GetMoreData rows) with a template that does not follow the columns, but instead displays a button which you click to get more data (more children for that row).

The RowStyleSelector looks like :

<local:MyGridRowStyleSelector x:Key="RowStyleSelector">

<local:MyGridRowStyleSelector.MoreResultsRowStyle>

<Style TargetType="telerik:TreeListViewRow"

x:Name="MoreResults">

<Setter Property="telerik:TreeListViewRow.Template"

Value="{StaticResource MoreDataCustomRowTemplate}" />

</Style>

</local:MyGridRowStyleSelector.MoreResultsRowStyle>

<local:MyGridRowStyleSelector.NormalRowStyle>

<Style TargetType="telerik:TreeListViewRow"

x:Name="NormalResults">

</Style>

</local:MyGridRowStyleSelector.NormalRowStyle>

</local:MyGridRowStyleSelector>

The MoreResults TreeListViewRow Control Template is taken from Blend "Copy Template" on the TreeListViewRow but I have simply replaced the PART_DataCellsPresenter with :

<ItemsControl x:Name="PART_DataCellsPresenter"

Grid.ColumnSpan="2"

Grid.Column="1"

ItemsSource="{Binding Path=Functions}">

<ItemsControl.ItemTemplate>

<DataTemplate>

<Grid>

<Button Content="{Binding}" />

</Grid>

</DataTemplate>

</ItemsControl.ItemTemplate>

</ItemsControl>

I have this basic structure working and the MoreResults rows show Buttons as expected, but there are exceptions that show up in the output window : A first chance exception of type 'System.ArgumentException' occurred in Telerik.Windows.Data.dll

Would this be the suggested approach or is there a better way, that doesn't cause the exceptions ?

Bound Column Headers

I need to use the datacontext of my gridview (or window) to bind my column headers. I tried both the gridview and window relativesource and got the same results. My initial view of the grid looks great - any of the columns that are displayed on the initial view have the correct headers. However, if you scroll to the right, any of the columns that weren't originally displayed don't have a header (the datacontext has the correct labels - I've checked). I made the window wider which meant that more column headers display but still not all. Is there some trick to getting all the column headers to bind?

I have attached pictures of the left and right side of the grid.

Here is an example of one of the data columns. Note: The values are displayed correct.

<telerik:GridViewDataColumn ColumnGroupName="ColumnsTrans" DataMemberBinding="{Binding Value1}" DataFormatString="{}{0:f2}" IsFilterable="False" IsReadOnly="True" Width="70" FooterTextAlignment="Right" >

<telerik:GridViewDataColumn.Header>

<TextBlock TextWrapping="Wrap" TextAlignment="Center">

<TextBlock.Text>

<Binding RelativeSource="{RelativeSource FindAncestor, AncestorType={x:Type Window}}" Path="DataContext.Label1" />

</TextBlock.Text>

</TextBlock>

</telerik:GridViewDataColumn.Header>

<telerik:GridViewDataColumn.AggregateFunctions>

<telerik:SumFunction Caption="" ResultFormatString="{}{0:N2}" ></telerik:SumFunction>

</telerik:GridViewDataColumn.AggregateFunctions>

</telerik:GridViewDataColumn>

ObjectContext vs DbContext

We're really excited about this control as it will really push us forward in a lot of heavy scenarios where "normal" programming falls apart. I have to echo a previous post that documentation should be a priority. I think people will simply skip over this if documentation isn't present.

The thing I'm fighting is this. We have in our N-Tier architecture a DbContext from a CodeFirst EF model and not a straight ObjectContext. The fluent api exposed by the DbContext is something we've been using for nearly 6 months now. I'm getting the underlying ObjectContext from the DbContext using the code below, but I am getting a Query Object Not Found error no matter which table I attempt to tie to. My guess is that, in reversing a DbContext back to an ObjectContext, I'm losing a lot of my definitions.

1. Do you support DbContexts?
2. If not (which I suspect is the answer), how could I use this control with a DbContext?

Thanks!

RadChartView with TimeSpan values?

I currently have a RadChartView control that is bound to some objects whose name is on the X-Axis (Horizontal) and total-time as a TimeSpan on the Y-Axis (Vertical). I would like the vertical axis to show labels such as 00:16:29.6 for sixteen minutes, twenty-nine and six-tenths seconds. I also want the vertical axis to automatically scale as it does with numerical values.

I have tried using the DateTimeContinuousAxis as the vertical axis which was bound to a DateTime with the hour, minutes, seconds, and milliseconds populated but the chart rendered the objects with a zero value. I have also tried just binding a CategoricalAxis to the TimeSpan property but that again renders all of the items with a zero value.

Does anybody know how to do this by overriding some classes or if there's any plans to include native TimeSpan representations in the RadChartView?

PivotGrid data loading status

Hello,

I am using Pivot Grid which has its DataProvider’s ItemSource as DataTable with large number of rows (around 500000).

Pivot grid takes some time to display this data and shows wait window which says “Loading…”.

Is there any way to find out status of DataProvider or PivotGrid control which indicates that data is being displayed in pivot grid control? I checked DataProvider Status and this is always “Ready” during this time. Actually pivot grid starts showing data only when DataProvider becomes Ready, but then if there is huge data to display, I want to do some operations during this time and also when data is fully shown to pivot grid.

Also I want to know if I can override default wait window and show my own wait window.

Kindly let me know if I can achieve this somehow.

Thanks,

Shiv Ram

WPF App: get Telerik binaries from install on target machine

Hello,

I have defined a WPF application that uses Telerik controls using Visual Studio 2010 SP1.

I have copied what is in Debug folder (.exe files and .dll binaries) to another machine and it worked great. However, I don't want the Telerik binaries to be copied along the exe file. I want the exe to work with the local install of Telerik on the target machine. I installed Telerik on the target machine and added the Paths to binaries to the System Environment Path variable. Yet, I couldn't run the .exe file yet.
How can I achieve this?

link of question on StackOverflow: WPF App: get Telerik binaries from install on target machine

What I tried so far:

I installed Telerik on the target machine and added the Paths to binaries to the System Environment Path variable. Yet, I couldn't run the .exe file yet. How can I achieve this?
I installed gacutil.exe and added the binaries to GAC. I can test: gacutil /l | findstr “Telerik” and find all assemblies I added.
I tried to place these assemblies (Telerik) in C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.0 trying both x64 and x86.
I tried to place these assemblies (Telerik) in C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5 trying both x64 and x86.

None of the above works. The only way is having the .dll files right next to the .exe in the same directory which I do not want.

Thanks,

RibbonView in 2013_2_0729 hotfix

Hello, I downloaded 2013_2_0729 hotfix and RadRibbionView doesn't work as before.
I'm using the below code (called from the OnContentRendered event of RadRibbonWindow).
_mainRibbon is a RadRibbonView instance and each tab in _mainRibbon is dynamically created.
This code worked fine in former versions, but after applying 2013_2_0729 hotfix, NullExceptionError occurrs in _mainRibbon.Visibility = Visibility.Visible;. Can this be fixed?

        private void createFeatures()
        {
            List<IPluginFactory> featureFactories = PluginManager.Instance.GetFactories(typeof(IFeatureFactory));
            foreach (IPluginFactory factory in featureFactories)
            {
                // Providing callback (delegate) to create any number of FeatureWindows from the feature
                IFeature feature = (factory as IFeatureFactory).Create(_mainRibbon, createFeatureWindow, create3DWindow);
            }

            _mainRibbon.SelectedIndex = 0;
            _mainRibbon.Visibility = Visibility.Visible;
        }
