Telerik good for our WPF app?

Hi all,

We are looking for 3rd party WPF controls for a new WPF project with the MVVM design pattern. We would like to use your grid, it should be easy to copy/cut/past rows and to recalculate fields because its a calculation program. Is this possilble with that control and why should we use yours and not DevExpress for instance?

Thank you for your answer.

Need to hide Minimize/Maximize Icon

Can you tell me if there is a way to hide the minimize/maximize Icon? Basically I am just going to using this control to surround basic forms because it has nice looking header that matches the rest of my application. If there is a better way to do this let me know, I am pretty new to WPF so maybe I am going down the wrong road here. Thanks!

ObservableCollection<T> - filter not applying to grid

Hi Telerik,

It seems to me the RadDataGrid is not updating it self when applying a filter to its datasource of type ObservableCollection<T>:

I've tried the same code - just using the standard ListBox - and that works as expected.
The filter is applied and the listbox is updated to only show the items that apply to the filter - but that doesn't work for the RadDataGrid:

Here's a little code example:

    
            //_availableOnBoardSalesProducts is of the type ObservableCollection<Products>  
        
            gridFood.ItemsSource = _availableOnBoardSalesProducts;  
        
            myListBox.ItemsSource = _availableOnBoardSalesProducts;  
        
            //Add an item to the ObservableCollection works fine in the RadDataGrid  
        
                    private void Button_Click(object sender, RoutedEventArgs e)  
        
                    {  
        
                        _availableOnBoardSalesProducts.Add(new OnboardSalesService.Products() { Price = 10m, Description = "MyDesc", Category = "MyCat" });  
        
                    }  
        
            //But applying a filter only works fine for the standard ListBox - not for the RadDataGrid  
        
                    private void Button_Click_1(object sender, RoutedEventArgs e)  
        
                    {  
        
                        ICollectionView view = CollectionViewSource.GetDefaultView(gridFood.ItemsSource);  
        
                        if (view.Filter == null)  
        
                        {  
        
                            view.Filter = delegate(object item)  
        
                            {  
        
                                bool result = ((OnboardSalesService.Products)item).Price == 10m;  
        
                                return result;  
        
                            };  
        
                        }  
        
                        else 
        
                        {  
        
                            view.Filter = null;  
        
                        }  
        
                    }

Thats a bug right?

I've also noticed that you have an Telerik.Windows.Controls.Core.RadObservableCollection<T> available.
Whats that for?

RowIndicatorVisibility

Hi Guys,

In the RadGridView, I have set the RowVisibilityIndicator="Collapsed". But there's a tiny gap on the left side of the gridview. How can I remove this gap? I also have the same issue with RadTreeListView. Is the approach going to be the same?

Thanks.

Sorting Programmatically Created Columns Not Working

Hello,

In my application, I have a RadGridView that contains columns that have been added via XAML as well as columns that are added dynamically in code. The problem I am seeing is that the columns added via code cannot be sorted or grouped, while there is no problem with the columns created in XAML. I have confirmed that the dynamically added columns have the IsSortable and IsGroupable properties set to true. Should this be all I need?

One important difference is that the programmatically added columns contain more complex property names than do the columns added in XAML. This results in the EffectiveSortMemberPath being set to something like "Experiments[0].WarpsPerBlock" (from the binding) on each of the dynamic columns. Could the "deep" property string cause sorting to fail?

Any help will be greatly appreciated!

Thanks,
Mark
