Is there any way to display Rad TreeView with ItemsOptionListType as CheckList and that particular TreeView should be a Read only kind of...???


Simply my requirement is to display Read only TreeView with checkbox's (not with Disabled mode)

I would like to persist the state and position of my Tileview to Isolated Storage, but am not sure of the best approach for this?

Can you steer me in the right direction?

Many Thanks

Hi,

I have a WPF radgridview, on a particular event (say button click) I want to change the selection on the grid to a different row based on some parameters. The grid is bound to a datatableview. I am setting it as

grid.SelectedItem = ((

 

DataView)grid.ItemsSource).Table.Rows[count];

 

 

grid.CurrentItem = ((

 

DataView)grid.ItemsSource).Table.Rows[count];

 

 

grid.BringIndexIntoView(count);

where count is the index of the row I want to select. Can you please tell me how to do it.

Good morning
As the title say, RadDragAndDropManager dont fire the DropQuery and DragQuery events.
in XAML:

                dragDrop:RadDragAndDropManager.DropQuery="rTreeListView_DropQuery"
                dragDrop:RadDragAndDropManager.DropInfo="rTreeListView_DropInfo"
                dragDrop:RadDragAndDropManager.DragQuery="rTreeListView_DragQuery"
                dragDrop:RadDragAndDropManager.DragInfo="rTreeListView_DragInfo" 
 
and, in code behind, there is the implementation of events.
Setting a breakpoint into the events, it's never hit.
Need the DropQuery event because, in my application, there are rules that allow or not 
the drop of an element under another element;
and (as i read from help) i would like to set the QueryResult to false, cancelling drop.
The second question is:
I would like to show an icon (like denial of access)  when the DragCueItem is on an item 
on which drop operation is not allowed.
 

Hi,

Assembly version :2011.2.823.40

I've got a weird issue on telerik radgridview:
i create and destroy columns on view code behind by the code :
myGrid.Columns.RemoveAt(i);
...
myGrid.Columns.Add(NewColumns);

when i rebind my grid, the new column is systematiquely at the place of the removed column but the header is wrong, the new header is at the end of the grid.

is someone had the issue before and know how to resolve that?

thanks by advance

Is there any way to get or set the HighlightedElement with the RadComboBox?  The HighlightedElement seems to follow the SelectedItem when there is a SelectedItem, but the highlight does not go away when SelectedItem is null.

Thanks.

I'm wondering if anybody has done any work extending DataFilter to handle dealing with child collections in a complicated manner. For instance, I have an IParent interface, which has an IEnumerable<IChild> Children member. I'd like to be able to express visually:

from p in parents where p.Children.Any(i => i.Type == 1 && i.Foo = "Bar")

Basically, I want to select parents based on whether any children exists.

I have this notion that I could implement this entirely on my own... somehow. Perhaps a custom 3-part editor control for teh Children property, with a "any" operator... and a sub-RadDataFilter rendered in part-3.

That seems pretty kludgy though.

Hi Support
I was able to bind combo according to this thread http://www.telerik.com/help/silverlight/raddatafilter-how-to-create-custom-filter-editors.html
but i don't know how to bind it to special value and Description, is there any idea?
<DataTemplate x:Key="ComboKind">

<telerik:RadComboBox DisplayMemberPath="Dsc"

                     SelectedValue="{Binding Value, Mode=TwoWay, FallbackValue=null}"/>

 

</DataTemplate>

P.S. Item Source contain ID and Dsc

Thanks in advance

Hi,

I have an issue about the scroll on my gridview.
My gridview contains a lot of data so there is vertical scrollbars and I set the insert row to visible.
The problem is when I enter data on the insert row and I press enter the gridview don't scroll to the the added row.
Here is my gridview:

I tried to use the event RowEditEnded in the code behind to scroll to the position of  the row like this but it didn't work:

Do you any solution about this issue?
Thanks

Hello all, 

we are having a big problem with radchart performance. I'll explain  an example to illustrate the situation. 

In one part of our app, a user control that contains 5 Radcharts is loaded. Each chart contains two series for a total of 10, and each series has exactly 2880 points in our database. Internally, each chart is set to use a sampling threshold of 200, X axis range is set to DateTime and AutoRange, and zoom settings are set to zoom and scroll. As these are multi-series charts, the schema we used is that found in Telerik's documentation (binding to nested collections), associating each series mapping to one collection index. 

As the user refreshes, one WCF call is asynchronously made to retrieve each series data (thus, 10 calls in total). The call returns really fast, and in around 2 seconds all the lists of points that feed the series are loaded in memory.

The problem arises when updating the charts's ItemsSource property. It takes a lot of time since the ItemsSource of each chart is updated until all the charts are shown in the screen properly (around 15-20 seconds!!). This is totally a mess for us, as our customer needs to change the date queries dinamycally and perform refresh operations frequently. Waiting for 20-25 seconds every time a refresh is made is not acceptable for him. 

Showing point marks, labels and so on is disabled, as well as animations. Please, could you provide any help for this?

I post the chart configuration code here:


And here, the function used to process the result of the asynchronous WCF call. As you can see, we make a local copy of the list returned by the WCF method inserting it in an ObservableCollection and then setting the ObservableCollection as an item of m_lstChartSource, which is a list and the object set as Chart.ItemsSource target. "ProcessChartSerie" makes additional processing regarding the serie (color, item mappings and so on):
