Filter ignoring INotifyPropertyChanged

Hi,

Should the grid filters update when a row's item implements INotifyPropertyChanged and fires PropertyChanged on a property used as part of a filter?

For example, I have a grid which has a collection (which implements INotifyCollectionChanged) and each item implements INotifyPropertyChanged and fires PropertyChanged when the IsActive property is changed. On the grid I had a filter on the IsActive property. When I enable / disable the filter it works fine, but if the IsActive property changes while the filter is enabled, the row is not then visible. If I disable / re-enable the filter, the row is visible.

Perhaps I need to manually bubble up PropertyChanged events to the collection and fire CollectionChanged?

Thanks,

Geoff

ComboBoxColumn - drop down on focus

I need to support having combo box columns display their drop downs when the cell is given focus, rather then the default behavior of clicking on the cell, then clicking on the dropdown arrow. Are there any examples of doing this?

Combobox Performance with many Elements

Hi.
I have created a RadComboBox containing some 10.000 elements.
This ComboBox is horrobly slow...
What can I do ?
My own Ideas vary from
a) Go, get your head checked, 1000 elements are the maximum if you don't want your users to die of old age in front of the screen
to
b) use the MagicallyAutoPaging="True" Property on the Combobox

Yours,
Nils

WPF RadGridView Filter

Hi,

I have 2 questions regarding the filtering behavior in WPF RadGridView, The first is how to get a DataTable from the filtered data without looping over the records property (maybe generate a Linq Expression from the FilterDescriptors).

The Second is how to clear all filters by code, i tried FilterDescriptors.Clear() this will cancel the filter for the data records but the filter interface still have checkboxes on the previous selected values.

Thanks.

Grid does not refresh when grouping and sorting used

HI,

I'm having some troubles with WPF RadGridView (v. 2009.1.312.35). I have a group description and sorting defined on one column.

Sometimes when the underlying collection (ObservableCollection) is being changed, the grid view does not refresh. I need to click on the header of the column to make it refresh and display source elements correctly.

Is there a way to fix this problem?

Thanks,

Ruben.

Customizing AutoHide windows in Docking view

Hi,

I wanted to do customize the autohide windows.

1. Remove the tab/icon which is used to expand the the auto hide window? I don't want to show the tab. Instead the windows would be expanded in response to a Button click or some other event. In my user interface, the icon is taking some space, which I don't want to part with. Also the icon doesn't look nice.

2. Also I want to prevent the users from docking this window, so I want to remove the 'docking' icon.

Pardon me if I didn't use the terminology correctly. To help explain what I am trying to do, please refer to the attached image, I want to get rid of the things marked in Red box.

GridView in TabControl: unable to assign items source

Hi,

I have TabControl called mainTabs with a TabItem called CurrentTasks. In the CurrentTasks TabItem I show a GridView (say RadGridView1) with a list of tasks which works fine. This GridView is populated in code behind with an ObservableCollection.

As per the logic, each task in the RadGridView1 has some dependent tasks called Predecessors Tasks(tasks that were completed before the selected task was assigned) and Successor Tasks(tasks assigned to other users which are depending on the current task to be completed by the current user).

Now, I want to make the rows of this RadGridView1 expandable so that I can show the details of selected Task in two tabs as Predecessor Tab and Successor Tab. Each of these tabs would have a GridView(say InnerRadGridView1 and InnerRadGridView2) showing a list of tasks respectively.

I am trying to assign the ItemsSource Property for InnerRadGridView1 programatically to an ObservableCollection in the code behind. The problem is that it does not show any intellisence for me to access the InnerRadGridView1 (for eg. I want to assign it as InnerRadGridView1 .ItemsSource = Tasks; where Tasks is my ObservableCollection).

Please provide me a solution to this issue. Im really stuck.

I am also attaching a screenshot of what exactly the navigation flow of my application is.

Cheers,

Syed Nadeem.

How to overlap bars

I can't seem to figure out how to overlap series bars (vertical or horizontal). For example, I have two sets of data and series two is always a subset of series one.

User    Total Sub
------- ----- -----
Bob        37    20
Jane      120    55
Jim        49    23
George      7     7
Sue       145   107

I can get bars side-by-side, but I'd like to float the lower value (it's ALWAYS lower) over the higher values to show comparison/progress. Ideas?
