Complete Drop on Mouse button up?

I am currently using the RadDragAndDropManager for the first time and dragging from a RadTreeView to a RadPaneGroup.
Seems to do most of what I need; I'm currently doing all the work on the DropInfoHandler.

The problem I have, is that the "DropInfo" event fires IMMEDIATELY when I drag the RadTreeViewItem over the pane, rather than when I let go of the left mouse button. This is an issue because I have multiple grids, and the user will want to drag over the top of some grids to get to other grids.

Is this functionality by design, or have I done something wrong?

XAML:

<telerik:RadDocking x:Name="Docking" Close="Docking_Close">

<telerik:RadSplitContainer InitialPosition="DockedLeft" Width="240" >

<telerik:RadPaneGroup>

<telerik:RadPane x:Name="rpDatabaseBrowser" Header="Database Browser">

<Grid>

<telerik:RadTreeView Name="RadTreeView1" ImagesBaseDir="/Images/" LoadOnDemand="RadTreeView1_LoadOnDemand" IsDragDropEnabled="True" telerik:RadDragAndDropManager.AllowDrop="False">

</telerik:RadTreeView>

</Grid>

</telerik:RadPane>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

<telerik:RadDocking.DocumentHost>

<telerik:RadSplitContainer>

<telerik:RadPaneGroup x:Name="rpg1" telerik:RadDragAndDropManager.AllowDrop="True">

<telerik:RadPane x:Name="rp1" Title="Pane 1">

<Grid>

<telerik:RadGridView x:Name="GridView1" Visibility="Hidden" DataLoadMode="Asynchronous">

</telerik:RadGridView>

</Grid>

</telerik:RadPane>

</telerik:RadPaneGroup>

<telerik:RadPaneGroup x:Name="rpg2" telerik:RadDragAndDropManager.AllowDrop="True">

<telerik:RadPane x:Name="rp2" Title="Pane 2">

<Grid>

<telerik:RadGridView x:Name="GridView2" Visibility="Hidden" DataLoadMode="Asynchronous">

</telerik:RadGridView>

</Grid>

</telerik:RadPane>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

</telerik:RadDocking.DocumentHost>

</telerik:RadDocking>

Code behind

public MainWindow()

{

InitializeComponent();

RadDragAndDropManager.AddDropInfoHandler(rpg1, OnDatabaseBrowserDropInfo);

RadDragAndDropManager.AddDropInfoHandler(rpg2, OnDatabaseBrowserDropInfo);

}

private void OnDatabaseBrowserDropInfo(object sender, DragDropEventArgs e)

{

//work out which RadTreeViewItem is dragged from

//work out which RadPaneGroup is dropped on

//populate Grid on RadPane

}

Keeping data type when Exporting ExcelML

Hi everybody,

I am exporting a radgridview, version: 2010.1.603.35 (I can´t change it)

My Grid has data this way (decimal) and it keeps the data-format really cool, works pretty well:

But I am unable to get the data when I export with the decimals:

As you can see in the result, I get the number 10000 instead 100,0 or 100 even. Maybe I am missing something.

Can you help me with this? Thanks in advance.

Moving content around document - bookmarks?

Hi

I have various Permission Ranges one after another, each followed by a carriage return. My aim is to reorder these ranges.

I've managed to cobble together some code that deletes the range of the one I want to remove and it inserts a fragment (fragment obtained prior to deletion via CopySelectedDocumentElements).

This mainly works... except if I have bookmarks in the range I want to copy, they get deleted. It would appear that copying the selected elemtents to a fragment ignores Bookmarks.

Any suggestions or workarounds welcome!

Filter button properties?

Just received and imported the newest DLLs into my project and it has made all of my existing filter buttons triple in size. This creates a massive hassle for everyone using this tool.

Are there size/placement properties available to set for the filtering button per column?

Thanks in advance.

How to convert filter Expression to Expression<Func<someType, bool>>?

I have some operations that require me to perform updates on items (in bulk, possibly hundreds of thousands, so on the server end), but restricted to the items filtered by the user in the grid. I'm aware of the Telerik.Windows.Data "Where" extension that returns an IQueryable given the grid's filter collection, and that IQueryable has an Expression property that seems to be just what I want.

The signature of my update statement is

Update<TResult>(Expression<Func<TEntity, TResult>> entity, Expression<Func<TEntity, bool>> predicate);

You can disregard the "entity" argument, that describes the data to be updated. How can I use Expression returned from the "Where" method populate the "predicate" argument?

Thanks!

Bar Chart -- How To Reflect DataPoint.IsSelected Changes?

What I am trying to do:
I have a bar chart with a series of data points which start out unselected. When I click on a data point in the chart or set the DataPoint.IsSelected property to true, I want the visual display of the bar to change so it stands out by adding a black border around it. So far, I have been unable to get the chart to reflect these selection changes.
Side note -- the Pie chart I did this for automatically has the "explosion" as the default ChartSelectionBehavior which is awesome.

How do I get the chart bars to reflect data point IsSelected changes?

Thanks in advance,

Tracy

Bind to array of arrays

Hi,

Is it possible to bind to an array of arrays?

We need to bind to some dynamic data, so we cannot pre-generate classes for the data items.
