RadGridView resize on form resize

Good day!
I have such a xaml:

<Window x:Class="CAP.AdminTool.Questions"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Вопросы" Height="700" Width="750" xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors" xmlns:dxb="http://schemas.devexpress.com/winfx/2008/xaml/bars" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" Icon="/CAP.AdminTool;component/favicon.ico" FontFamily="Verdana" FontSize="13" Loaded="Window_Loaded" >
    <Grid >
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" MinHeight="60"></RowDefinition>
            <RowDefinition Height="auto" MinHeight="30"></RowDefinition>
            <RowDefinition Height="auto" MinHeight="60"></RowDefinition>
            <RowDefinition Height="auto" MinHeight="30"></RowDefinition>
        </Grid.RowDefinitions>
        <telerik:RadGridView Grid.Row="0"
             HorizontalAlignment="Left"
             Name="grQuestionSets"
             VerticalAlignment="Top"
             Height="auto"
             MinWidth="700"
             AutoGenerateColumns="False"
             SelectionChanged="grQuestionSets_SelectionChanged" >
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn Header="Раздел вопросов" UniqueName="Name" Width="auto" MinWidth="300"/>
                <telerik:GridViewDataColumn Header="Описание" UniqueName="Description" Width="auto" MinWidth="400"/>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>
    </Grid>
</Window>

I want my RadGridView width to change when I change the width of the window.
How can I do it?

Menu icon image binding and visibility

1) When I bind the menu icon to an image which is defined as a StaticResource, the image does not appear but I can see the text "pack:" What am I doing wrong?

2) I want to bind the visibility to the underlying datasource using the BooleanToVisibilityConverter, so that when a menu item is selected the image is visible. I know how to use the converter but where in xaml do I set the binding.

Datasource:

    
            public partial class Toolbar : UserControl 
        
                { 
        
                    public Toolbar() 
        
                    { 
        
                        InitializeComponent(); 
        
                        this.zoomMenu.ItemsSource = GetZoomMenuItems(); 
        
                    } 
        
                    private ObservableCollection<ZoomMenuItem> GetZoomMenuItems() 
        
                    { 
        
                        return new ObservableCollection<ZoomMenuItem>() 
        
                        { 
        
                            new ZoomMenuItem(){ IsSelected=false, ZoomSetting=10, ZoomSettingText="10%" }, 
        
                            new ZoomMenuItem(){ IsSelected=false, ZoomSetting=25, ZoomSettingText="25%" }, 
        
                            new ZoomMenuItem(){ IsSelected=false, ZoomSetting=50, ZoomSettingText="50%" }, 
        
                            new ZoomMenuItem(){ IsSelected=false, ZoomSetting=75, ZoomSettingText="75%" }, 
        
                            new ZoomMenuItem(){ IsSelected=false, ZoomSetting=100, ZoomSettingText="100%" }, 
        
                            new ZoomMenuItem(){ IsSelected=false, ZoomSetting=200, ZoomSettingText="200%" }, 
        
                            new ZoomMenuItem(){ IsSelected=false, ZoomSetting=400, ZoomSettingText="400%" }, 
        
                            new ZoomMenuItem(){ IsSelected=false, ZoomSetting=600, ZoomSettingText="600%" }, 
        
                            new ZoomMenuItem(){ IsSelected=false, ZoomSetting=800, ZoomSettingText="800%" }                 
        
                        }; 
        
                    } 
        
                }

Menu:

    
            <BitmapImage x:Key="tickImage" UriSource="../Images/tick.png" DecodePixelWidth="10"/> 
        
            <Style x:Key="ZoomMenuItemStyle" TargetType="telerikNav:RadMenuItem"> 
        
                        <Setter Property="Icon" Value="{Binding Source={StaticResource tickImage}}" />

            <HierarchicalDataTemplate  
        
                        x:Key="zoomMenuItemTemplate" 
        
                        ItemsSource="{Binding ZoomMenuItem}"> 
        
                        <TextBlock Text="{Binding ZoomSettingText}" /> 
        
            </HierarchicalDataTemplate> 
        
            <telerik:RadDropDownButton

Cause all items UIElements to load

Hi All

I have bound the ItemSource of the RadBook to an ObservableCollection of classes, then I am using the item template to create a user control that binds it DataContext to the object. This is working well. I found however that I need to ensure that all the UserControls are loaded as soon as the ItemSource of the RadBook is Updated. Right now they only load when you navigate to that page.

Is there any method that I can call that does not require me to cause the book to iterate through all the pages?

Thanks for you help

Nick

Problem Clicking To Select

Hi,

I've set up a RadComboBox with the following configuration:

IsTextSearchEnabled="True"

IsFilteringEnabled="True"

TextSearchMode="Contains"

SelectedItem, SelectedText, IsDropDownOpen and Text are bound to my data. I can start typing and click to select an item once, but if I search (type) again and click on the same item a second time, it is not selected. Only the text I typed is displayed in the combobox.

After removing IsFilteringEnabled and TextSearchMode, clicking the item a second time works as expected. Adding either of them will re-create the problematic behavior.

Is anyone aware of a workaround?

Thanks,

Andrew

Asynchronously adding images via URL to grid rows

I have a grid view containing several hundred rows, each of which will need to contain an image referenced via a URL. These images will come from a remote server via http.

Using an imagecolumn, with the image source bound to my arraylist containing the URL, the grid does not display until all images are downloaded, which takes some time and causes the UI thread to be unresponsive. I need to add the images asynchronously so that the rest of the row data is visible but the images appear one by one as they are downloaded (as a standard web page would).

How can I best achieve this?

Many thanks.

Time granularity

Hi,

I use a RadTimePicker as a CellEditTemplate in a RadGridView with binding a DataTable.
I managed to bind the data to the TimePicker and it displays correctly (e.g. 12:23:59), but I can change its value only to timestamps in hour (e.g. 12:00:00). How can I change its value to such a date as 23:34:56?

Thanks in advance!
