Hi,

Please bear with me as I am a newbie to WPF and we are evaluating RadGridView as part of a new development project. I have a issue with filtering and grouping on columns.

I have another Grid with Contact information with and a related table that stores other contact information, such as address details. If I have the Grid bound to a datarecord type of Contact and want to have related columns such as Address.Line1, Address.Line2 displayed on the parent GridRow. What is the best way to acheive this? I can get the information display but my issue is that I can not use the Filter or Groups on the Address columns. I have attached some simple code behind that I am using, Name works as expected, however Address.Line1 displays data but can not use filtering or the grouping functionality

Any help is greatly appreciated.

Hi,

I am trying to prevent dropping of items on level other than their own , i.e., items on a specific level cannot be moved to level above or below). For this, I am working with PreviewDragEnded and if the item is not being dropped to the same level, i prevent it by setting e.Handled to true. It works fine when DropPosition is DropPosition.Inside. However, when the DropPosition is After or Before, the TargetDropItem is null ,for some reason, and I cannot check the level to which the item is dropped. The TargetDropItem gets a value on DragEnded event but it's already too late. Is there a way to do it?
Thank you,
Tal

Hello all,

Hello. I have a small problem with the treeview. I change manually the icon of a treeviewItem from the code depending on some db changes any couple of seconds but the icon does not change in the treelist unless I click that item. What is the problem?
Thanks

Hi. I would like to know if there is a way I can disable the DataContext property of a TreeViewItem so it will not fire for changes. I am not using DataBinding and I would like to use that DataContext just for keeping the object I am displaying to the user. Or maybe there is another way I can keep an object in the treeViewItem. Thanks

I had a gridView which is bind to a DataTable's DefaultView. Now, i want to set Row Style according to row state, i.e., if rowstate is Modified i want that row in Red color, if it is added then in green color. How do i achieve this?

Thanks

Hi

I am getting the above error trying to implement one of your WPF examples.

Please can you tell me where I am going wrong.

Evaluating the Telerik controls and so far so good.  Just wondering if the RadPanelBar implements fully the IsTextSearchEnabled?  I have a PanelBar setup and bound to a List<CustomObject>.  Furthermore, I have setup a HierarchialDataTemplate.  In this example, CustomObject exposes a property named ItemDescription.  I have overridden the ToString method of the class to return ItemDescription and I have set (on the PanelBar) TextSearch.TextPath="ItemDescription"

However, none of this appears to work.

Thanks,
David

Hi,
I am using custom sorting.
I've tried to follow some suggestions in other thread regarding the use of Loaded event to set the initial sorting state for my columns.

void GenWiseRadGrid_Loaded(object sender, RoutedEventArgs e)
        {
            if (ItemsControl != null)
            {
                Sorting += GenWiseRadGrid_Sorting;

                if (DataContext != null)
                    ApplySortToGrid(BaseProvider.DefaultSort);
            }
        }

        private void ApplySortToGrid(ISort pSort)
        {
            if (pSort == null) throw new ArgumentNullException("pSort");

            var name = BaseProvider.DefaultSort.DataProperty.PropertyName;
            var column = Columns[name];

            column.SortingState = BaseProvider.DefaultSort.Order.IsAscending ? SortingState.Ascending : SortingState.Descending;
            column.HeaderText = "test";

the ApplySortToGrid gets called, but the control does not repaint/refresh.

I've tried :
  InvalidateVisual();
            InvalidateArrange();
            UpdateLayout();

           
Nothing seems to get the control to repaint/ refresh...




We are not using SortDescriptions
if (SortDescriptions.Count > 0) throw new Exception("WE SHOULD NOT USE SORT DESCRIPTORS");

  <telerik:GridViewDataColumn HeaderText="Category Name" UniqueName="Category_name"
                                                    IsCustomSortingEnabled="True"
                                                    DataMemberBinding="{Binding Category.Category_name}"                                                >
                        </telerik:GridViewDataColumn>

Also I've noticed that the data is STILL sorted internally (so i return a list in a certain order but the grid will show it desc). I am doing the DESC already internally in my SQL engine .

Any idea???
