Difficulty styling RadCalendar in RadDateTimePicker

I'm having a brutal time styling the RadCalendar nested in RadDateTImePicker.

Mainly, when I follow the instructions here:

http://www.telerik.com/help/wpf/raddatetimepicker-styling-raddatetimepicker.html

The resources are not created in my ResourceDictionary as documented. I'm simply presented with one style and control template; it appears to be using the native styles built into the control natively instead of spawning the resources in the above walk through.

I'm able to style my own header elements, but getting at the colours for the Calendar grid is where I'm stumped--it's using the 'office black' theme colours.

Any help is appreciated.

UpdateSourceTrigger=PropertyChanged ignored in the GridView

I've looked through your forum about this but can only find half working workarounds.

Consider the following GridView:

<telerik:RadGridView ItemsSource="{Binding ItemsView}" AutoGenerateColumns="False"

IsSynchronizedWithCurrentItem="True"

ValidatesOnDataErrors="InViewMode"

EditTriggers="CellClick"

CanUserDeleteRows="True"

CanUserInsertRows="True">

<telerik:RadGridView.Columns>

<telerik:GridViewComboBoxColumn Header="Currency"

DataMemberBinding="{Binding CurrencyCode,UpdateSourceTrigger=PropertyChanged}"

ItemsSource=

"{Binding Path=DataContext.AllCurrencyCodes,RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type UserControl}}}"

/>

<telerik:GridViewDataColumn Header="Rate"

DataMemberBinding="{Binding Rate,UpdateSourceTrigger=PropertyChanged,NotifyOnValidationError=True,ValidatesOnDataErrors=True}"

/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

Here I bind to POCO objects that implement INotifyPropertyChanged. As soon as a change is detected, I light up a Save button.
However, the property does not get changed until the user steps out of the cell, thus preventing the immediate click on the save button!

There is a workaround for simple textboxes;

<telerik:GridViewDataColumn Header="Rate"

DataMemberBinding="{Binding Rate,UpdateSourceTrigger=PropertyChanged,NotifyOnValidationError=True,ValidatesOnDataErrors=True}">

<telerik:GridViewDataColumn.CellEditTemplate>

<DataTemplate>

<TextBox Text="{Binding Rate,UpdateSourceTrigger=PropertyChanged,NotifyOnValidationError=True,ValidatesOnDataErrors=True}"/>

</DataTemplate>

</telerik:GridViewDataColumn.CellEditTemplate>

</telerik:GridViewDataColumn>

However, this trick fails miserably for Date-fields, since your otherwise great date picker gets supressed. :(

I really want a fix for this, that I consider a bug. Is there any chance of that ever happening?

Clear Selection

I have placed a radlistbox in a dropdown button. I have SelectionMode = Single. I have an event handler for the selectionchanged to know which item they selected. In that handler I set the dropdown button to close, get the item and clear the selection. I do this so that the next time the user opens the menu there is not an item selected in the listbox. I have tried 3 different things but the highlight of the item does not go away. I have tried:

SelectedItems.Clear();
SelectedItem = null;
SelectedIndex = -1;

As previously stated, none of these clear the UI selection. The SelectedItem property is set to null, but all previously clicked on items are still highlighted in the UI.

Thanks in advance,
Lee

Gridlines not working?

I have the following chart set up where I would like to display gridlines:

<telerik:RadCartesianChart Grid.Row="1">

<telerik:RadCartesianChart.Behaviors>

<telerik:ChartTrackBallBehavior />

<telerik:ChartPanAndZoomBehavior ZoomMode="Horizontal" />

</telerik:RadCartesianChart.Behaviors>

<telerik:LineSeries ItemsSource="{Binding PraGasProductionChartPoints}"

CategoryBinding="Date"

ValueBinding="Value">

<telerik:LineSeries.HorizontalAxis>

<telerik:DateTimeContinuousAxis Minimum="{Binding MinimumChartDate}"

Maximum="{Binding MaximumChartDate}"

LabelStyle="{StaticResource labelFontStyle}"

MajorStepUnit="Year"

MajorStep="3"

LabelFormat="yyyy"

/>

</telerik:LineSeries.HorizontalAxis>

<telerik:LineSeries.VerticalAxis>

<telerik:LinearAxis LabelFormat="#,#" />

</telerik:LineSeries.VerticalAxis>

</telerik:LineSeries>

<telerik:RadCartesianChart.Grid>

<telerik:CartesianChartGrid MajorLinesVisibility="XY" />

</telerik:RadCartesianChart.Grid>

</telerik:RadCartesianChart>

My chart displays fine but I don't get any gridlines to show up on the chart. I assume I'm doing some basic thing wrong. Please help.

Thanks,
Mike

[Solved] GridViewCommandColumn

Hello friends,

I have a RadGridView in which I want to give Edit as the last column. I want it to be either a link or a button so that when I click on Edit(which is there as the last column value for all the rows), I can display a page in which I can give provision for editing the fields. I cannot use inline edit option since I cannot display all the columns of the data source in the grid. But when user clicks on Edit, the user must be able to edit all the fields of the data source rather than what is being displayed in the grid. How can I do this??

When I did a search I found that GridViewCommandColumn can be used for similar purposes but I don't know how to add this coulmn through xaml.

Please help.

Thanks in advance
Priya

telerik:GridViewComboBoxColumn filtering functioin error

Hi Guys,

I used telerik wpf gridview to bind a collection source, the every data item have a foreign key related other tables, so I use the GridViewComboBoxColumn to show the relation and make user can change it . below is my code

<telerik:GridViewComboBoxColumn Header="{common:Translate Group}"

UniqueName="ColourGroupingID"

DisplayMemberPath="Description"

ItemsSource="{Binding ColorEntityCollection}"

SelectedValueMemberPath="ColourGroupingID" DataMemberBinding="{Binding ColourGroupingFk}"

>

</telerik:GridViewComboBoxColumn>

In above code, you can see ColorEntityCollection have two properties used for valuePath and displayPath of combobox, dataItem's ColourGroupingFk is foreign key. Everything is ok, but the filtering, the gridview unexpectedly filtered by ColourGroupingFk , not expected DisplayMemberPath : Description . Please see attachment.

How can I do this? PS: I also set Gridview's FilteringMode = FilteringMode.FilterRow for using a header filter row. I read many threads on forum, many thread recommand :
<telerik:GridViewComboBoxColumn.FilteringControl>
<Controls1:ComboColumnFilteringControl />
</telerik:GridViewComboBoxColumn.FilteringControl>

But our team don't need popup filter window, only row filter. Please help me.. Thanks very much!

Runtime error when project output type is Class Library

Telerik: 2012.2.912.40 (RadControls for WPF Q2 2012 SP2)
OS: Windows 7

Problem: I have a WPF Class Library project, after dragging a DataPager to my UserControl, I get "Could not load file or assembly 'Telerik.Windows.Controls.Data, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The system cannot find the file specified."

But if I make my project's output type to Windows Application, my project runs fine.

Is there an issue with DataPager and wpf class library projects?

Please help.

Thanks,
Mark
