Does the TabControl.ItemsSource property support CompositeCollection?

Hello,

I am trying to style the RadMap, and within that, I am trying to style the PART_MapCommandBar and PART_MapZoomBar which are the button which contains the options to change the type of view (RoadView, AerialView, BirdsEyeView), and whether the labels should be shown or not, and the button which contains the options to change the zoom level (World, Country, Region, Neighborhood). I obtained the styles of these components using Object -> Edit Style options, but after the styling, the commands of the buttons no longer work. Could you help me out as to what could be the issue and how to solve it?

The styles generated are as follows: 

For the Map Zoom Bar:

How can I set the style on buttons I add programatically?

I have the toolbar defined like so:

<toolbar:RadToolbarTray
HorizontalAlignment="Left"
x:Name="screenToolbar"
VerticalAlignment="Top"
telerikControls:StyleManager.Theme="Windows7" />

Then I add buttons like this:

var button = new Button();
tbar.Items.Add(button); //tbar is a toolbar object

The buttons don't pick up the style of the tray... on the 
silverlight side, I explicitly set the style of the button 
before I add it to the toolbar (app resource), but I don't 
see a way to pick up the toolbar button styles from the StyleManager...

Hi,

in the german resource file of the gridview are two misspellings (for the filtercontrol)

in english the values are:
"Is contained in" and "Is not contained in"
your german translation are "Enhalten" and "Ist nicht enhalten".

In both there is a "t" missing after the leading "en" --> "Enthalten" and "Ist nicht enthalten"

However, the meaning of the function is not clear with this translation.
So, my proposal for "Is contained in" is "Ist enthalten in" and for "Is not contained in" it is "Ist nicht enthalten in".

Well, will it be fixed?

Thanks.

Hi,

In some of my gridview's when I click for the second time on the insertrow then rowvalidating is triggered before I commit the newrow with the enter key.
When I do the insert with the insert key  then there's no problem I cannot pinpoint this problem, any ideas?
Thanks,

Thomas

Hi,

I have referred  the sample( http://www.telerik.com/community/forums/wpf/gridview/can-t-use-celledittemplateselector-amp-celltemplateselector-together.aspx) for setting CellTemplate by using CellTemplateSelector.

I modified this sample to use DataTable as source instead of List<Item>(). In this case, i am not able to see any data in the second column of the Grid.

The code i have changed is:
public MainWindow()
{
InitializeComponent();
//List<Item> items = new List<Item>();
            //items.Add(new Item() { PropertyName = "Property1", PropertyType = typeof(string), PropertyValue = "blabla" });
            //items.Add(new Item() { PropertyName = "Property1", PropertyType = typeof(Visibility), PropertyValue = Visibility.Visible });

            DataTable items = new DataTable();
            items.Columns.Add("PropertyName");
            items.Columns.Add("PropertyType",typeof(Type));
            items.Columns.Add("PropertyValue");
            DataRow row1 = items.NewRow();
            row1[0] = "Property1";
            row1[1] = typeof(string);
            row1[2] = "blabla";
            items.Rows.Add(row1);
            row1 = items.NewRow();
            row1[0] = "Property1";
            row1[1] = typeof(Visibility);
            row1[2] = Visibility.Visible;
            items.Rows.Add(row1);         
this.dataGrid1.ItemsSource = items;
}

class PropertyValueDataTemplateSelector:
public override System.Windows.DataTemplate SelectTemplate(object item, System.Windows.DependencyObject container)
{
           var r= item as System.Data.DataRow;
           Type value= r["PropertyType"] as Type;
           if (value == typeof(string))
                return this.TextTemplate;
            else
                return this.EnumTemplate;
}

Not able to figure out what is the issue.
Please give updated sample using DataTable as ItemSource.
Thanks for your help.

Hi,
I am using RadGridview which Itemsource is Observablecollection<CustomObject>
While editing particular cell, i want to change the another cell's content which is read only.
For Example:
Public class CustomObject
{
 public string Identifier{get;set;} 
 public string  DisplayName{get;set;}
}

My requirement is when i change the Identifier, need to change the "DisplayName" value.
I tried to change the "DisplayName" value in both CellValidated and CellValidating event. But not able to see the updated value in the UI.
I tried grid.Rebind() in both CellValidated and CellValidating event, the current cell (i.e Identifier) modification is getting lost and the updated DisplayName  value is shown in the UI.
How to modify the other column value based on some cell value changes and refresh the GridView?

code snippets:

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            grid.CellValidated -= new EventHandler<Telerik.Windows.Controls.GridViewCellValidatedEventArgs>(grid_CellValidated);
            grid.CellValidated += new EventHandler<Telerik.Windows.Controls.GridViewCellValidatedEventArgs>(grid_CellValidated);
            grid.ItemsSource = GetObservableList();         
        }      

        void grid_CellValidated(object sender, Telerik.Windows.Controls.GridViewCellValidatedEventArgs e)
        {
            Telerik.Windows.Controls.RadGridView g = e.Cell.DataColumn.Parent as Telerik.Windows.Controls.RadGridView;
            //Modify the DisplayName cell  value.
            var currentObj = e.Cell.DataContext as CustomObject;
            currentObj.DisplayName = "Test";
            var list = g.ItemsSource as ObservableCollection<CustomObject>;
            CustomObject p = list.Where(obj => obj.UniqueKey == currentObj.UniqueKey).FirstOrDefault();
            p = currentObj;
            p.DisplayName = "Test";
        }   
        private static ObservableCollection<CustomObject> GetObservableList()
        {
            ObservableCollection<CustomObject> table = new ObservableCollection<CustomObject>();
            for (int i = 0; i <= 3; i++)
            {
                CustomObject p = new CustomObject();
                p.UniqueKey = "aa" + i;
                p.Identifier = "des" + i;
                p.DisplayName = "arfea" + i;
                table.Add(p);
            }
            return table;
        }

        public class CustomObject
        {
            public CustomObject() { }
            private string _key = null;
            private string _identifier = null;
            private string _displayName = null;
            public string UniqueKey { get { return _key; } set { _key = value; } }
            public string Identifier {get { return this._identifier; } set { this._identifier = value;}}
            public string DisplayName { get { return this._displayName; } set { this._displayName = value; } }
        }
    }

XMAL:
 <Grid>
        <telerik:RadGridView  x:Name="grid" x:FieldModifier="public"  AutoGenerateColumns="False" ItemsSource="{Binding}">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding UniqueKey}" Header="UniqueKey" UniqueName="UniqueKey"  />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Identifier, Mode=TwoWay}" UniqueName="Identifier" Header="Identifier"  />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding DisplayName, Mode=OneWay}" UniqueName="DisplayName" Header="DisplayName" IsReadOnly="True" />               
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>        
    </Grid>

Hi,

How do I define a checkbox column in WPF GridView control?

Thanks

I created a Windows WPF project and am using the RadGridView that has a child table using a TableRelation. I want to be able to hide the expand/collapse image if there are no child records. I saw an example or two that were similar to what I wanted, but populate the grid by adding records within a loop. I am assigning the ItemSource of the grid and DataSource of the GridViewTableDefinition and haven't been able to find an example of what I want that populates the grid in this way. I tried using the "PreviewDataRecordCreate" event, but it doesn't seem to fire when assigning the ItemSource. I would really like to avoid adding records by looping through the data. I looked through the API and didn't see anything obvious, but will continue to look. Have I just overlooked something or is there not a simple way to do this? Thanks.

Dear Sir,
