Going by your examples, I set the AllowDrop for the RadListControl to true. I also have set the SelectionMode to MultiExtended. Also, per your example in the TreeView section, I coded the RadListControl's MouseDown event to call the DoDragDrop() method. However, now I can not select rows with the mouse. I can select extended with the arrow keys and shift key, and I can drag them into the TreeView, succesfully. It's like the mouse only works for Dragging, it won't even control the scroll bar in the RadListControl.

Basically I did everything you wrote in the Treeview "Enabling Drag and Drop" section, except I used a RadListView instead of a Windows listbox for the source control. It works with a Windows listbox, but I would like to use the Telerik version.

Help Please.

some bugs

We've bought Devexpress in 2009 and use it all the time.Last week,we found telerik can write WPF-like window form,so we downloaded and tried it to evaluate to buy or not.we found some problem which prevent us from using it.
     1.when we place a radtreeview in the form,and click "open property builder", in the RadTreeView Property Builder dialog,we can't see OK,Cancel and Apply button.It seems Property Builder dialog have the same problem.
      2.Sample or demo program have region and language problem.We can't build the demo at first,after changing region and language to english,we can build it.I found there are many "..." characters [0x85] in the program,which will lead to some problem in other region code.
      we tried it in many computers and  these problems still exist.

[Solved] RadMaskedEditBox context menu missing

I have upgraded to RadControls for WinForms Q2 2011 (version 2011.2.11.831) from Q3 2010 SP1 (version 2010.3.10.1215)

In Q3 2010, the RadMaskedTextBox supports a right click menu. In Q2 2011, it does not.

Am I doing something wrong ? (my code hasn't changed). I noticed that it still does exist on the RadTextBox.

If it was removed (or is a bug), how do I recreate/enable the right click functionality.

Thanks,
Chet

RadControls for WinForms 2011 Q2 installer fails looking for previous version

I attempted to reinstall RadControls for WinForms 2001 Q2 (8/31/2011) after being unable to use the designer for the new RadPage controls in Visual Studio 2008. I tried a repair installation; when that didn't work, I uninstalled it completely. Now when I try to install, the installer reports the error:

The feature you are trying to use is on a network resource that is unavailable.

Click OK to try again, or enter an alternate path to a folder containing the installation package 'RadControls_WinForms_2011_1_11_419_dev.msi' in the box below.

The installer I'm using is RadControls_WinForms_2011_2_11_0831_dev.msi', located on my desktop.

I've downloaded another copy, thinking the file may have gotten corrupted, but I received identical results the second time. When I tried to select the installer by browsing to my desktop file, I get the error that the installer "is not a valid installation package for the product Telerik RadControls for WinForms Q1 2011", then reference the "_419_dev.msi" file again.

I thought Q2 was out of beta, but I'll install Q1 if it works. What do I need to work around this error?

Issue with RadGridViewExcelExporter using RadGridview

To summarize what I am attempting to do, I am attempting to export data items from a RadListView (databound) to Excel using a RadGridview and RadGridViewExcelExporter.

This is actually a 2-part issue:
The first issue involves populating with data the RadGridView object that is passed to the RadGridViewExcelExporter (see below).

void Export_to_Excel(String myExcelFile)

{

RadGridView myGridView = new RadGridView();

myGridView.DataSource = myDataSet.joberrors;

RadGridViewExcelExporter exporter = new RadGridViewExcelExporter();

exporter.Export(myGridView, myExcelFile, "Sheet1");

exporter = null;

myGridView = null;

}

myDataSet.joberrors is the datasource of my RadListView and contains 2 rows and 14 columns. Using the above code, myGridView contains 0 rows and 0 columns even after the datasource is set.

To solve this I used

myGridView.LoadFrom(myDataSet.joberrors.CreateDataReader());

now myGridView is successfully populated with data, but the second problem now rears its head...

After exporting the data to Excel using the RadGridViewExcelExporter , the exported worksheet only contains one column - the primary key of myDataSet.joberrors?.

Any ideas what I am doing wrong? Is there an easier way to do this?

Thanks

[Solved] AutoGenerateHierarchy in GridView

Hi,

I want to use AutoGenerateHierarchy, but I am having a hard time, telling the grid to not show certain columns. I added child templates with the name in the properties of the object being displayed, and marking these columns as not visible, but these templates just get ignored.

How can I control what which columns get displayed when using AutoGenerateHierarchy ?

thanks.
