How many data series I have in a RadChart ?

Hi,

I want to disable some buttons when I have more that one dataseries in the chart. So I have chosen DataBound event of chart. But I can not access to number of dataseries which was loaded into grid at that moment. I have seen number of data series in some private properties of chart by using Quick Watch window but I can not see in public ones (number of data series).

Thanks in advance.

Drag and Drop From ListBox To RadTileView to insert between Tiles

Hi,

Need your advice on this scenario. I have a ListBox where I drag my items from, to be dropped into a RadTileView. I am able to do a typical drag and drop action, where the dragged item is appended to the ItemsSource of the TileView. But I wish to implement the case where I can drop the item and insert it (instead of append) into the position I want. How do I go about doing this? Thanks for your time.

P.S. I'm not sure this should be posted here or the RadTileView forum. For now, I only posted here.

CellEditEnded from extended GridViewColumn

I'm extending a GridViewComboBoxColumn, setting IsComboBoxEditable to true, and trying to provide code to add typed text as items into the ItemsSource collection.

I hooked the CellEditEnded event of the GridView and added some test code to play with this idea:

private void TestGrid_CellEditEnded(object sender, Telerik.Windows.Controls.GridViewCellEditEndedEventArgs e)
{
var comboBoxColumn = e.Cell.Column as Telerik.Windows.Controls.GridViewComboBoxColumn;

// only continue if its a cell for the column we're interested in
if ((comboBoxColumn == null) || (comboBoxColumn.UniqueName != "Lookup"))
return;

// get back the object used to represent the row
var gridItem = e.Cell.DataContext as GridItem;

// only continue if the text typed is not in the list
if (gridItem.SelectedLookupItem != null)
return;

var cellComboBox = (RadComboBox)e.EditingElement;
var lookupItemCollection = cellComboBox.ItemsSource as ObservableCollection<LookupItem>;

var newItem = new LookupItem() { Name = cellComboBox.Text };
lookupItemCollection.Add(newItem);

//set the typed item as the selected item
gridItem.SelectedLookupItem = newItem;
}

Works great. Now I want to move that code into my extended GridViewComboBoxColumn. How could I hook/override the CellEditEnded from inside the extended column?

Associating items in two collections/grids

I have two different collections with items of type A and B where B contains a child collection of type A and I'm displaying these two collections in two different RadGridViews and what I want to do is to be able to drag an item from one grid to the other so that I can add the appropriate item to the child collection (thus building a relationship between the two collections). I'm fairly new with WPF and just can't seem to see how to modify the examples to accomplish this DnD scenario. I'm guessing that I have to call the appropriate RadDragAndDropManager static methods for each row of the grid but as my grids are bound to my collection (via a View Model) I'm not sure how to do this or if it's the correct approach.

Any help/pointers would be greatly appreciated!

Expanding Column Headers Does Not Display Horizontal ScrollBar

I'm sure there is some property I am missing, but I am having an issue on initial load of the grid.

Given the following code, if I expand the width of "Column 1" to the right, I never get the horizontal scrollbar visible to scroll to view the hidden columns. This happens with EnableColumnVirtualization set to "True" as well.

<Window x:Class="WpfApplication1.GridWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

Title="GridWindow" Height="300" Width="600">

<Grid>

<telerik:RadGridView EnableColumnVirtualization="False">

<telerik:RadGridView.Columns>

<telerik:GridViewColumn Header="Column 1" />

<telerik:GridViewColumn Header="Column 2" />

<telerik:GridViewColumn Header="Column 3" />

<telerik:GridViewColumn Header="Column 4" />

<telerik:GridViewColumn Header="Column 5" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

</Window>
