Hello,

I am creating an application that will bring up a messagebox after an item has been dragged and dropped from one treeview to another. I would like the messagebox to prompt the user with a Yes/No after the drop is complete on the second treeview. If the user selects no, the drop can then be canceled.

Thanks
Ryan

RadDragAndDropManager.AddDropInfoHandler(this.CreatedStepItems, new EventHandler<DragDropEventArgs>(this.CreatedStepItems_OnDropInfo));

private void CreatedStepItems_OnDropInfo(object sender, DragDropEventArgs e)

{

if (e.Options.Status == DragStatus.DropComplete)

{

var t = MessageBox.Show("Cancel", "Cancel", MessageBoxButton.YesNo);

if (t == MessageBoxResult.Yes)

//Cancel

else

//Dont

}

Highlight GridViewRow when GridViewCell is selected

I have the RadGridView setup with

SelectionUnit="Cell"

SelectionMode="Extended"

Is there any way to highlight the current row (obviously in some color that is not the same as the cell highlight) when I have selected a cell in it? I was able to make a style that changed the row color when the mouse was over it, but that's not really what I need.

Basically I want it to work like SQL Management Studio does when you click the row number.. it selects the row... but as far as I can tell there is no way to mix the selection mode.

Change CellTemplate and CellEditTemplate based on content of another column

I want to change the CellTemplate and CellEditTemplate of GridViewDataColumn, based on the value of another column.

eg. If Column A has drop down box, with two entries: TextBlock and ComboBox. Based on the selection of column A, I want the column B to have that control.

If you can provide me some sample code that accomplishes this it would be very useful.

TreeView SelectedItem doesn't work

Hi, I am building an application where I need to represent some hierarchical data in a tree. The standard WPF tree fell short on many fronts. So I am doing a trial of your WPF controls.

One of the big issues with the standard tree was that it was not (easily) possible to select an item within the tree from outside the tree. I was looking at your documentation, and it clearly shows that you can indeed use the SelectedItem property on your RadTreeView to set the selected item in the tree.

So I have implemented your tree and am trying to use that property to set the item, but I cannot get it to work. I have tried both through declarative binding and by setting the property programmatically, and in either case the RadTreeView does not set the correct item on the tree. It simply does nothing.

What am I doing wrong? If I can get that feature working with your RadTreeView, along with proper node Double-clicking, we will be purchasing at least developer licenses of the WPF RadControls.

Here is the TreeView code I am doing declaratively:

<t:RadTreeView Grid.Column="0" Grid.Row="2"

MinHeight="100" MinWidth="100"

DataContext="{Binding Source={x:Static SizingApp:ProjectManager.Instance}}"

SelectedItem="{Binding CurrentSelected}">

Now the Projects property that the first node ItemsSource is bound to works just fine. However, the SelectedItem property on the TreeView itself seems to do nothing. Both the Projects property and the CurrentSelected property are both DependencyProperties. Both have call back event handlers that fire off INotifyPropertyChanged PropertyChanged event handlers indicating the properties have changed. I have other controls on the application that are bound to CurrentSelected and they change along with CurrentSelected just fine.

So why doesn't the RadTreeView also?

Additional data format for clipboard

Hi everybody,

the clipboard functionality of the RadGridView is exactly what I need to exchange data with excel. But we also have the requirement to provide the data in additional application specific format. Is there a way to use the standard clipboard functionality for text format and combine it with own functions to provide the data in an application specific format?

New To Telerik Trying to empty a chart

Hi,
I'm brand new to Telerik and I'm feeling kind of stupid.
I have a 2D Stacked Bar Chart

I am trying to refresh the data after a set interval. I'm creating a dashboard application.
Whenever I refresh the data the new data is just getting added to the old data.
I tried setting the itemsource to nothing but it does not seem to make any difference.

The code I'm using was basically cannibalized from one of the demos and I really don't know what I'm doing.

First off how do I remove the data before adding it again?

Second is there a good place someone can point me to, to learn more about the following objects?
SeriesMapping, DataSeries, ItemMapping, DataPointMember.... I'm having a hard time understanding when to use what.

Thanks in advance and I apologize for my ignorance.
Tim

How to format a GridView Cell using CellTemplateSelector.

Hi
I have a GridView that shows a bunch of rows and has 15 columns, let me name them A1, A2, A3, M1, M2, ...to M12.
Each "M" column can have a value that is either "1" or "0".
I want to show the cell that are "1" with background="Black" and those that are "0" with Background="White".

Following the documentation I use a class CellTemplateSelector that implement a DataTemplateSelector ( object item, DependencyObject container ).

In the documentation the Template selector is used for formatting one column of the GridView based in its value.So it works for one column in the whole row.

In my case I need to call my CelllTemplateSelector from every "M" column cell in the row and decide what format apply to the cell based on its value (0 or 1).

If I use the Selector implemented in the documentation, I notice that when I call it, I get the parameter "item" that gives me the whole row but I don't know what column I am calling from.

I need to get the column from where I am calling from in order to check for the value of that specific column in order to select the template to apply.

So my question is: How should I call my TemplateSelector and pass the row but also the column name I am calling from..

Thanks
