Hello!

I would like to style a GridViewCheckBoxColumn triggered if the CheckBox is readonly or not. The differense between true and false is to small.

<telerik:GridViewCheckBoxColumn Header="Klart"

DataMemberBinding="{Binding ChKlar, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"

IsReadOnlyBinding="{Binding Uppdaterbar, Mode=OneWay}"

EditTriggers="CellClick"

AutoSelectOnEdit="True" />

Any Ideas?

Best regards / Anna

RadComboBox in a popup

I have a RadComboBox in a popup and when I click the drop down button, it closes the popup. This does not happen with the standard ComboBox. Is there a way to prevent this?

Problem with RadTabControl

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);
        }
