Telerik grid has several events like UserAddedRow and RowsChanged which are fired when I add/edit row on master grid.
I can't find equivalent events for a hierarchical subgrid.
Can somebody give me some direction please?
Same event will be fired for the child templates as well, so you do not need to look for equivalents.

I have a UserControl in WPF and it contains a variety of controls in it... The most important being the DataGrid Control. The DataGrid control is bound to an Observable Collection list. This list filled with different items based on couple of filters selected by the user. Now, once the DataGrid displays all the data. I want to set the Focus on the first (Filters) combobox on my usercontrol. Is there any way to know when the DataGrid has completely loaded??? Is there any DataTrigger I could set that i could trigger to inform me that Grid was refreshed with new list and I can set the ComboBox to focus. Basically i'm not able to set the focus to the first control on my UserControl when the data in the DataGrid has been repopulated... Please let me know if anyone knows how to resolve this issue!!
Thanks in advance.
I hate to work in code behind but sometimes that is only way. This can be done in two ways according to me:
Use EventAggregator to raise the event from your ViewModel once you are done with your filtering logic in it. Listen to this event in view code behind and in the handler do firstCombo.Focus()
Second is bit dirty, So there must be the button or the last control after which you apply filter on your listview. In the buttonClickHandler/or any event of the last control (like selectionchange) directly do firstCombo.Focus(). In this case the moment you will press your button focus will move to combo.
Thanks
I am trying to work though the best approach to accomplish the following. Within a page I have it divided into two section. On the left a listbox and the right is empty. (Grid etc). What I would like to accomplish is when an item is selected from the listbox a different user control loads in the right panel. For example if I have three items (one, two three) selecting one would load a red user control, two would load a blue user control and three a green user control.
I was taking this approach since Content Template / Data template selectors are not available in SL. However if anyone has another suggestion I would be grateful for your thoughts.
I'm creating this with MVVM in mind and traditionally I have managed this within the code behind of the user control however I have seen mention of how this could be managed within the ViewModel as well.
Any suggestions or guidance on a best approach is always appreciated.
Cheers
You can bind both listbox selected item and user control visibility properties to the same property in the viewModel.
Then just use a valueConverter for each user control to switch on/off the visibility.
Please tell me if i should elaborate/add a code sample.
I have a DataGrid that is displaying Data. I want to implement view switching functionality in WPF. I have read online and they say it's not possible with Data Grid .
There is also a topic that explains thumbnail view:
WPF: ListView with icons view?
But how to implement the same three view in the same control?
To be exact, I want the functionality like Windows Explorer where we can change the view from a dropdown list.
Some help in this regard would be great.
You are right. This is not something that the DataGrid supports. You can create your own views for the ListView, see the following article:
How to: Create a Custom View Mode for a ListView
I want to display data from and XML document in a tree-like display but I don't need items to be selectable and I don't want them to be collapsible.
Any way to do this with TreeView? Is TreeView even the right control to use?
Thanks!
You can handle the PreviewMouseDown and cancel the event. If you need to allow scrolling, you can do a HitTest and see if it is over the "ScrollerChrome". If you need more details, I can provide code.
I want to create my own expandable/collapsable tree-like UserControl, which nodes are the Border elements with any content. And this control should have the single SelectedItem. When I select one of the nodes I want to see details information about selected item.
I've done the control's presentation and a piece of logic:
I can see all the tree of elements, collaps any node(s), select one of them and see details. But I can't do bidirectional binding. I.e. I want to have an opportunity to change fields in details panel and immidiately see changes in the tree-control.
Help me please either call force update (rebind data) of the control (just give a tip how to perform this) or give an advise how to create my own List-like UserControl.
I tried to make my control inherit from some ListBox class but I couldn't.
PS. Sorry for my bad English...
Use the TreeView control.
