Drag & Drop buttons not firing click event

Hello,

I have an application that can drag and drop buttons between borders. I have the drag drop working.

The problem is the button click event seems to be blocked when I set the AllowDrag property to true. I can still see a double click event, just not the actual click event.

<Button Content="drop btn"

Click="Button_Click_1"

telerikDragDrop:RadDragAndDropManager.AllowDrag="True"

MouseDoubleClick="Button_MouseDoubleClick" />

Thanks for the help.

Add new row not working

When I set my grids datacontext as follows the Add new Row does not work:

dataGridView.DataContext = linqToSqldataContext.GetTable<my_Table_name>().AsEnumerable();

But If I set my datacontext like this it works but then my data in the grid is not binded to the source anymore:
dataGridView.DataContext = linqToSqldataContext.GetTable<my_Table_name>().AsEnumerable().ToList();

Can you explain why this is?

This is just a simplified version of what I am doing. Ideally I want to do the following and have all the data binded without having to process inserts/deletes/and updates for my data source.
dataGridView.DataContext = (linqToSqldataContext.GetTableByName(TableNames.SelectedItem.ToString()));

where GetTableByName is

static class DataContextExtensions

{

public static ITable GetTableByName(this DataContext context, string tableName)

{

if (context == null)

{

throw new ArgumentNullException("context");

}

if (tableName == null)

{

throw new ArgumentNullException("tableName");

}

var dataTable = context.GetType().GetProperty(tableName).GetValue(context, null);

return (ITable)dataTable;

}

BindingListCollectionView Position not updating

I am binding a GridView to a BindingListCollectionView. This is being filled by a Linq Query.

I am displaying a GridView of a few fields and a set of text boxes that also display these fields and several others. The Idea is for GridView to provide Sorting and Filtering on the key fields and make the rest of the fields visible when the record is displayed.

This works great if I navigate the GridView with the keyboard, but as soon as I use the mouse to select the record instead of the keyboard aarow keys, the position in the BindingListCollectionView is not updated.

To recap, the BindingListCollectionView position is updated when the grid is navigated with the keyboard arrow keys, but not when rows are selected with the mouse.

Any Ideas on how to work around this problem?

Dynamic columns but hide some

Hi, I'm have an unusual requirement here. We want to bind the gridview to any strong-typed objects but at the same time, we're not going to hide some columns. So this basically precludes us from defining columns in XAML. So my option is to handle an event which is fired during the creation of columns. There I could probably suppress the creation of some columns. Is there such an event?

gridview-multiple-selection

http://www.telerik.com/help/wpf/gridview-multiple-selection.html

In the above link API, RadGridView has a

ObservableCollection<object> SelectedItems

property. I have a requirement where I need to access the selected grid items in the ViewModel. How can I do that? There is no dependency property for that I can use, and in the code sample you only have codebehind example. Please advice.

Thanks!

Sources for RadBook

HI.

What are the different sources that can be used for the RadBook? I know that you can use images, but what else?.
Can you use a word/ppt/pdf document as a source? Up to now, I had to convert all pages to images, load them in an observable collection, and point the collection as the source for the RadBook.

Can I assign a word document as a source, without doing any conversions?

Regards

Hide Tab Item Header

We have a requirement to drive our tab control from elsewhere in the application, and so, the header tabs have become unnecessary.

Is there a way we can hide the tabs in a RadTabControl? Or, is there a better control for our needs?

TIA

Connectors not displayed

Hello,

I am using Version 2011.2.920.40

We shows connectors for series label in chart.
And when we are increasing window size, we are also changing Series item label font size dynamically(by applying custom Series Item Label style).
