Thanks for the help

Hey there!

I'm using Q1 2010 ComboBoxColumns in my GridView. For multi-editing 1-n items in my GridView i added a SelectionColumn and some controls outside the GridView so i can select as many items i want and use the outside controls for setting the properties for the selected items.

Furthermore it should be possible to edit one GridViewItem by setting the property directly by choosing from the ComboBoxColumn at the specific row. It would be great if i can do so without unselecting the other selected items. GridView.SelectedItems return all selected items of course, GridView.CurrentItem or GridView.SelectedItem returns the first selected item. I guess the GridView knows which row i'm editing because of the "cursor-editing" icon on the left side when clicking into one row.

For my purpose it is mandatory to retrieve this information in my CodeBehind, because i'm using 5 GridViewComboBoxColumns and their items are depending on the other selected ComboBoxItems, so if i select an item from the first ComboBoxColumn, the items of the second ComboBoxColumn have to be filtered because of my selection.

So i need to get the current row in my CodeBehing or a nice way to filter the ComboBoxColumns by DataBinding or any other way.

Looking forward to hearing from you.
All the best,
Markus

Hello Telerik Team,

I need a way to bind a SeriesMapping.LegendLabel to a custom object in code behind.  Can anyone provide an example of how to do this?

Hi,
after I installed the latest build, 210.1.430.35,
my gridviewcomboboxcolumn gives exceptions, also cellstyle doesn't seem to work properly.
After  an item is added  to the itemssource of the comboboxcolumn inside the roweditended event handler of the radgridview, the following exception occurs after leaving this eventhandler:

Hello,

I have a usercontrol that has a gridview in it binded to an observablecollection defined as a property of the usercontrol.
I need a 3 level cascading comboboxes on 3 columns, and I need to bind them to either properties or methods defined inside the usercontrol code behind class.
I've tried several things but I think I'm missing something, I'm kind of new to how binding works on wpf.
I'm trying to set the binding like this:


Where Operations is a Property of the UserControl, but I think it's trying to find Operations as a property of the Databound Object.

Any help would be appreciated.

Hello!

I have a custom RadPane control which inherits from RadPane.

I use the MVVM design pattern.

I programmatically add Panes to a RadPaneGroup contained in a DocumentHost.

I add one of my custom RadPanes. Everything is fine. Then I add another one - still fine.

I switch back to the first one and all content is gone - for example textboxes are empty, DropDownLists are in default selected state etc.

I switch back to the second one - same story.

In debug mode I can see that the custom RadPanes still have their respective ViewModel as DataContext and these ViewModel also have their properties correct but by switching between panes, these properties don't seem to bind to their respective controls (Textboxes, DropDownLists ...) anymore or the controls don't update their values correctly.

Hi.

I have a problem with setting up Selected event for RadPanelBar.
My aim is to catch an event when RadPanelBarItem is selected.

I am using DataTemplate for Item, and EntityObject entityObject containing a List<Employee>

XAML:
Resources:

<Window.Resources>

<DataTemplate x:Key="RadPanelBarItemTemplate">

<StackPanel MouseLeftButtonDown="pnlEmployee_MouseLeftButtonDown" Background="Transparent" Name="pnlEmployee" Orientation="Horizontal" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">

<Image Source="{Binding Photo}" Stretch="Uniform" HorizontalAlignment="Left" VerticalAlignment="Stretch" Width="50" Height="50"></Image>

<Label Name="lblEmployeeName" Height="50" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Content="{Binding Name}" />

<Label Name="lblEmployeeID" Content="{Binding Id}" Visibility="Hidden" />

</StackPanel>

</DataTemplate >

</Window.Resources>

 

 

RadPanelBar: 

 

<telerik:RadPanelBar Grid.Row="1" Name="rpbLeftMenu" ExpandMode="Single" Selected="rpbLeftMenu_Selected">

<telerik:RadPanelBarItem Name="rpbiEmployee" IsExpanded="True" ItemsSource="{Binding Employees}" ItemTemplate="{StaticResource RadPanelBarItemTemplate}">

<telerik:RadPanelBarItem.Header>

<StackPanel HorizontalAlignment="Left">

<Label Name="lblEmployees" Content="Сотрудники"></Label>

<TextBox HorizontalAlignment="Left" Name="txtEmployeesFilter" TextChanged="txtEmployeesFilter_TextChanged" Width="200"></TextBox>

</StackPanel>

</telerik:RadPanelBarItem.Header>

</telerik:RadPanelBarItem>

...

</telerik:RadPanelBar>

 

 

CodeBehind:

Getting data from DB:

My solution for selecting Item event is to handle a StackPanel MouseLeftButtonDown event:

 

But it works only when clicking correctly inside a stackpanel.

I want something like this:

  

 

 

 

But I can't set Selected event handler for Items which are binded like mine:
ItemsSource="{Binding Employees}" 

How should I catch selection of Items?

Best regards,

Hi, I'm new to using your controls, but so far I'm liking it alot :)

I'm building a grid displaying data in a two level hierarchy which is easily achieved, but I was wondering if it was possible to display the rows of the second level in the same "master grid" in stead of generating a new gridviewdatacontrol? In my scenario this would give the best user experience.

Thanks in advance,

Best regards,
