Hello all,

I'm using RadGrid to displays items from a table. One of the column in a row stores the path to a file, how do I get the value of that particular column on double click (on the row) so that I can displays the file's path and display the file (I'll be using DocumentViewer to display the file.)

Thanks,

Kenny.

Data Context

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

RadPanelBar IsTextSearchEnabled

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

Changing column SortingState --> no refresh (paint)

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???
