Hello,

I am using the simple theme.

Is there any way by code to localize the contents of the popup that appears
when pressing on the filtering icon found on a grid header column ?

Thanks,

Hi,
We swithed to the most recent version a couple of days ago because we wanted to use the radtoolbar and now our gridview do not display new item that we insert into our collections. We're using CSLA and prior to upgrading everything was ok.

Hello

I want to build a hierarchy with a ComboBoxColumn
both the rows of the child grid
and the items of the ComboBoxColumn
need to be filtered
this is the way I work
and now OnChildGridLoaded I get a mistake 
for this line
var dataRowView = (DataRowView)((RadGridView)sender).ParentRow.DataContext;
Unable to cast object of type 'System.Data.DataRow' to type 'System.Data.DataRowView'.

I have a grid that has 2 columns. Column one contains a Characteristic and column two contains a Value like:

Characteristic | Value

The second column of the grid for "Value" contains a ComboBox.

The list of choices in the Value Column's ComboBox will depend on the Characteristic selected in Column 1.

Is it possible to do this and if so could someone provide an example?

Thanks,

Hi,

i have heared that you have had a special offer. Is it right that there was a week where the RadControls have been for free???? I heared that and actually i cant believe that...

M.M.

 Using Visual Studio 2008 SP1 and .NET 3.5 SP1. I have a simple test project with 2 tables, PARENT and CHILD, linked by foreign key. I created the ADO.NET Entity Data Model, and named the relationship that represents the database foreign key (FK_PARENT) to Children in the PARENT entity. My goal here is to bind a grid control to PARENT.Children so the user is editing only child records for the selected parent, and in this case, it is a new PARENT record.

I have a WPF form, with 2 tabs, tab1 and tab2.

tab1 has some fields where I capture data for PARENT, then on tab2 I have a Telerik RadGridView control, bound to parent.Child (which is the association that represents the foreign key from CHILD -> PARENT).

1) I enter the data, then click tab2 (which causes tab1's LostFocus event to fire and I call entities.AddToParent(parent)
2) I use the insert key (for the Telerik RadGridView) which calls the AddingNewDataItem event, which indeed ends up adding the records to my CHILD table just fine.
3) The inserted record has the correct PARENT key.

PROBLEM: The grid shows a new empty row, with no columns, period. Just an empty grid. The database record is actually correct, however.

If I bind the grid directly to entities.CHILD, I see all CHILD columns correctly. It is the binding to the relationship that causes this problem.

To alleviate the data provider, I tested both on SQL Server and SQL Anywhere 11, but get the same results.

Essentially, I have a parent entity in scope, I want to add child entities, and I want a bound control to show those immediately, and also to allow editing.

Code here:

public partial class Window1 : Window { Entities entities; PARENT parent; bool saved = false; public Window1() { InitializeComponent(); entities = new Entities(); parent = PARENT.CreatePARENT(Guid.NewGuid().ToString(), "00000"); gridViewChild.ItemsSource = parent.Child; } private void buttonOk_Click(object sender, RoutedEventArgs e) { entities.SaveChanges(); } private void buttonCancel_Click(object sender, RoutedEventArgs e) { } private void tabItemParent_LostFocus(object sender, RoutedEventArgs e) { if (!saved) { // Create the parent parent.FIRST_NAME = this.textBoxFirstName.Text; parent.LAST_NAME = this.textBoxLastName.Text; parent.MIDDLE_NAME = this.textBoxMiddleName.Text; parent.ZIP = this.textBoxZipCode.Text; entities.AddToPARENT(parent); saved = true; } } private void gridViewChild_AddingNewDataItem(object sender, Telerik.Windows.Controls.GridView.GridViewAddingNewEventArgs e) { // Entity Framework supports identity (server side generated) keys but we // must provide a default key value first. CHILD child = CHILD.CreateCHILD(0, "Test"); parent.ChildProfile.Add(child); e.NewObject = child; } }

Help.

Hi all,

when using DataView as ItemsSource for my chart I faced performance problem or my WPF application finally does no longer response.

I take a DataView to filter the underlying DataTable data as following:

MyChart.ItemsSource = null;
DataView view = new DataView (MyDataTable);
view.RowFilter = "SUPPLIER LIKE 'MC21*";
MyChart.ItemsSource = view;

When comming the the last assigning statement of ItemsSource my application doesn't response.
This happens especially, when using the SUPPLIER Column as the XCategory of the chart.

Do you have any idea?

Thanks,
San

I'm trying to update my project to use the latest release (2009.2 813), but when I sort on any column, I get this exception:

I want to do the following which I can do with most of the itemcollections in the ms toolbox.

I want to be able to bind a custom property on an object to the SelectedProperty of a row in a gridview. The result would be that you could select multiple rows in a gridview and then each of the objects in the list that the Grid was bound to would have their IsSelectedProperty set to true.

Example of TreeView:
So each TreeViewItem IsSelected property is bound to the bound objects IsSelectedProperty.

 

<

 

Style x:Key="{x:Type TreeViewItem}" TargetType="{x:Type TreeViewItem}">

 

 

 

    <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}" />
    ....
    ....
</Style>

Is this possible with the GridView?

Thanks,
