Hi,
I am using a RadTabControl and the RadTabItems are created using a datatemplate. I am having an RadPanelbaritem as accordion inside the tabcontrol. I am using MVVM model and there is no code behind. when the tab selection changes, the search will be based on the tab id and if i click on the panelbaritem, the search will be done within that panelbaritem. If i click again on the same tab(Selection Changed will not be fired here) the search should be done for that tab id. Since there is no click event for the tab control and the selection changed event will not fire within the same tab, i used MouseLeftButtonUp event to capture the click event. but during clicking of the radpanelbaritem, it even triggers the mouseleftbuttonup event instead of Accordion Selection Changed event. Which event should i capture for refreshing the tab?

Thanks in advance
R.Saranya.

Paging to the SelectedItem

I saw a post from the May timeframe indicating that switching to the page of a specific row was not possible. Has there been any progress on this issue?
http://www.telerik.com/community/forums/wpf/gridview/paging-focus-sepecific-row.aspx#1197073

What we're trying to achieve is a 'quick navigation' style grid, where the user has a text box at the top that they can use to search across all columns and then snap to the selected item on a specific page.

Thanks in advance.

Custrom Filter Editors

Hello,

I want to implement a ComboBox in two of my FilterDescriptors. I do exactly the same as in the Demos, and it does not work at all. My ComboBox return value is String, I checked it and it returns the value I want. But the DataFilter does not filter the DataGrid. It work with the regular text input method, but not with the ComboBox.

Here is what I've done:

<DataTemplate x:Key="RegionFilterEditorTemplate">

<telerik:RadComboBox SelectedValue="{Binding Path=NAME, Mode=TwoWay, FallbackValue=null}" DisplayMemberPath="NAME" SelectedValuePath="NAME"

MinWidth="100" SelectionChanged="RegionSelected"/>

</DataTemplate>

<DataTemplate x:Key="MUNFilterEditorTemplate">

<telerik:RadComboBox SelectedValue="{Binding Path=NAME, Mode=TwoWay, FallbackValue=null}" DisplayMemberPath="NAME" SelectedValuePath="NAME"

MinWidth="100" SelectionChanged="MunicipalitySelected"/>

</DataTemplate>

<local:MyEditorTemplateSelector x:Key="MyEditorTemplateSelector">

<local:MyEditorTemplateSelector.EditorTemplateRules>

<local:EditorTemplateRule PropertyName="N_MUN.N_REGION.NAME"

DataTemplate="{StaticResource RegionFilterEditorTemplate}"/>

<local:EditorTemplateRule PropertyName="N_MUN.NAME"

DataTemplate="{StaticResource MUNFilterEditorTemplate}"/>

</local:MyEditorTemplateSelector.EditorTemplateRules>

</local:MyEditorTemplateSelector>

<telerik:RadDataFilter Name="CitiesFilter" Source="{Binding}" Loaded="CitiesFilter_Loaded" AutoGenerateItemPropertyDefinitions="False" CanUserCreateCompositeFilters="False" EditorCreated="OnRadDataFilterEditorCreated" EditorTemplateSelector="{StaticResource MyEditorTemplateSelector}" >

<telerik:RadDataFilter.ItemPropertyDefinitions>

<datafilter:ItemPropertyDefinition PropertyName="N_MUN.N_REGION.NAME" PropertyType="{Binding String, Source={StaticResource Types}}" DisplayName="Област" />

<datafilter:ItemPropertyDefinition PropertyName="N_MUN.NAME" PropertyType="{Binding String, Source={StaticResource Types}}" DisplayName="Община" />

<datafilter:ItemPropertyDefinition PropertyName="NAME" PropertyType="{Binding String, Source={StaticResource Types}}" DisplayName="Населено място" />

</telerik:RadDataFilter.ItemPropertyDefinitions>

</telerik:RadDataFilter>

<telerik:RadGridView x:Name="CitiesGrid" ItemsSource="{Binding FilteredSource, ElementName=CitiesFilter}"

AutoGenerateColumns="False"

IsReadOnly="True"

ScrollMode="RealTime"

CanUserReorderColumns="False"

GridLinesVisibility="Both"

IsFilteringAllowed="False"

ShowGroupPanel="False"

ColumnWidth="Auto">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="{x:Static res:CitiesDialogFormRes.REGION}"

DataMemberBinding="{Binding Path=N_MUN.N_REGION.NAME}"

Width="Auto"/>

<telerik:GridViewDataColumn Header="{x:Static res:CitiesDialogFormRes.MUN}"

DataMemberBinding="{Binding Path=N_MUN.NAME}"

Width="Auto" />

<telerik:GridViewDataColumn Header="{x:Static res:CitiesDialogFormRes.CITY}"

DataMemberBinding="{Binding Path=NAME}"

Width="Auto" />

</telerik:RadGridView.Columns>

</telerik:RadGridView

And the .cs file:

                  

private void OnRadDataFilterEditorCreated(object sender,Telerik.Windows.Controls.Data.DataFilter.EditorCreatedEventArgs e)
        {
 
            switch (e.ItemPropertyDefinition.PropertyName)
            {
                case "N_MUN.N_REGION.NAME":
                    regionComboBox = (RadComboBox)e.Editor;
                    regionComboBox.ItemsSource = db.N_REGION.OrderBy(N_REGION => N_REGION.NAME);
                    break;
                case "N_MUN.NAME":
                    munComboBox = (RadComboBox)e.Editor;
                    break;
                    
            }
        }
 
private void CitiesFilter_Loaded(object sender, RoutedEventArgs e)
        {
            FilterDescriptor regionsFilterDesc = new FilterDescriptor("N_MUN.N_REGION.NAME", FilterOperator.IsEqualTo, "", true);
            FilterDescriptor munsFilterDesc = new FilterDescriptor("N_MUN.NAME", FilterOperator.IsEqualTo, "", true);
            this.CitiesFilter.FilterDescriptors.Add(regionsFilterDesc);
            this.CitiesFilter.FilterDescriptors.Add(munsFilterDesc);
        }
 
private void RegionSelected(object sender, SelectionChangedEventArgs e)
        {
            regionComboBox = (RadComboBox)e.OriginalSource;
            var selectedRegion = regionComboBox.SelectedValue;
            munComboBox.ItemsSource = db.N_MUN.Where(N_MUN => N_MUN.N_REGION.NAME.Equals(selectedRegion)).OrderBy(N_MUN => N_MUN.NAME);
        }

Dock on MouseDoubleClick

When using docking from ActiPro there is a nice feature:
- when you undock a ToolWindow/Pane, you can use MouseDoubleClick to dock the window back in the original place. Nice!

Does Telerik Docking have something alike? Or is it easy to implement?

Localisation: Binding column headers to DynamicResources

Hello,

I am currently implementing a localization in our application. The headers of the columns and all captions of all controls are referenced to dynamic resources like that:

<telerik:GridViewDataColumn DataMemberBinding="{Binding ArtikelNr}" Header="{DynamicResource ArtikelNr}" IsReadOnly="True"/>

I am switching the culture during runtime with this function:

public class ResourceManager

{

public static void SetResources(Collection<ResourceDictionary> collection, CultureInfo culture)

{

RemoveOld(collection);

try

{

Uri resource = new Uri("Resources/Strings_" + culture.Name + ".xaml", System.UriKind.Relative);

collection.Add(new ResourceDictionary { Source = resource });

}

catch

{

// TODO: Handle this, is it possible to be here?

}

private static void RemoveOld(Collection<ResourceDictionary> collection)

{

for (int i = 0; i < collection.Count; ++i)

{

if (collection[i].Source.ToString().Contains("Strings_"))

{

collection.RemoveAt(i);

--i;

}

public static List<CultureInfo> SupportedCultures

{

get

{

return new List<CultureInfo>()

{

new CultureInfo("de-DE"), // DEU

new CultureInfo("ru-RU"), // ENU

};

}

public void SetCulture(CultureInfo culture)

{

Thread.CurrentThread.CurrentCulture = culture;

Thread.CurrentThread.CurrentUICulture = culture;

ResourceManager.SetResources(Resources.MergedDictionaries, culture);

}

The column headers of the gridview are ignoring the dynamic resources. But the resources are correctly added to the MergedDictionaries-Collection. All other controls (RadControls too) are using the dynamic resources fine.

Do have any ideas what's going wrong with the columns?

TreeView Search with HierarchicalDataTemplate

After combining the code from multiple examples in the forum, I am really close to getting my search working for my TreeView. However, as other people have found, it will only work if I expand my whole tree first. What do I need to modify in my code to make this work correctly? Obviously, if my users have to expand the whole tree first, the search option is pretty useless.

thanks!
