Hi

     i an usin treeview. How can i stop dragdrop between nodes but requies drag drop within a node item.

like
NodeA
        A
        B
        C
        D
NodeB
        E
        F
        G
        H
The item should be dragging within items of NodeA not within Item of NodeA and NodeB

Hey :)
After trying and failing I decided to ask here.

Respected Sir,

Problem's Objective:Drag and Drop a row and also multiple row from RadGridview to RadTreeView item . 

Problem's Description : Well , i m having the RadgridView whose itemsource is binded with observableCollection and this GridView's itemsource  changes according to TreeView Item selected. Now i m trying to achieve Draging the gridview's row to TreeView Item but i m not getting the same 

I have viewed several post where by in Radgridview's xaml  Drag and Drop Functionality for its row is set as below:

 

<

 

 

gridView:RadGridView AutoGenerateColumns="True" x:Name="gridView"

 

 

 

 

UseAlternateRowStyle="False" dragDrop:RadDragAndDropManager.AllowDrop="True"

 

 

 

 

Grid.Column="1" Margin="30">

 

 

 

 

<gridView:RadGridView.RowStyle>
<Style TargetType="gridViewElements:GridViewRow">

 

 

 

 

<Setter Property="dragDrop:RadDragAndDropManager.AllowDrag" Value="True" />

 

 

 

 

</Style>

 

 

 

 

</gridView:RadGridView.RowStyle>

 

 

 

 

</gridView:RadGridView>

 

 

 

 

 
I want above thing in programatic way in code bind file in c#.

Also i m not to get the visibilty of Draging the row... i have done following things

 

 

RadDragAndDropManager.AddDragQueryHandler(this.gvEmail, OnDragQuery);

 

 

RadDragAndDropManager.AddDragInfoHandler(this.gvEmail, OnDragInfo);

 

 

EventManager.RegisterClassHandler(typeof(GridViewRow), RadDragAndDropManager.DropQueryEvent, new EventHandler<DragDropQueryEventArgs>(OnGridViewRowDropQuery));

 

 

EventManager.RegisterClassHandler(typeof(GridViewRow), RadDragAndDropManager.DropInfoEvent, new EventHandler<DragDropEventArgs>(OnGridViewRowDropInfo));

 

 

 

 

void gvEmail_RowLoaded(object sender, RowLoadedEventArgs e)

 

{

 

if (e.Row is GridViewHeaderRow || e.Row is GridViewNewRow || e.Row is GridViewFooterRow)

 

 

return;

 

 

var row = e.Row as GridViewRow;

 

 

this.InitializeRowDragAndDrop(row);

 

 

}

 

private void InitializeRowDragAndDrop(GridViewRow row)

 

{

 

if (row == null)

 

 

return;

 

row.SetValue(

RadDragAndDropManager.AllowDragProperty, true);

 

 

//row.SetValue(RadDragAndDropManager.AllowDropProperty, true);

 

}

 

As i m newbie to the Telerik please give your valuable suggestions.

Thanks in advance.

Hello,

I just upgraded to 2009.Q3 and, I'm struggling with the migration from Q2 to Q3.  Is there any good resource I can go to "do what I did with Q2 in Q3"?   A translation from the obsolete properties/methods to the new ones would be highly appreciated

Ok, the concrete issue I'm seeing right now is related to the code below (minimalist version):

myGrid.ItemsSource = myDataTable;
myGrid.AutoGeneratingColumn += myGrid_AutoGeneratingColumn;

After performing these operations, I see that myDataTable.Columns.Count = 25 and myGrid.Columns.Count = 0, and the event handler AutoGeneratingColumn is never executed.

Please help,
Marco

HI Guys,

I just noticed that Isselected property is no longer existing in Q3 release. How can I set the first row to be selected in code behind?

Hello

I've just installed the Q3 release and it looks to be working well!  I've come across one issue so far.  I have a lot of clickable cells in my grids, which are used to drill down further into the software and retrieve more detail.  These have all stopped working since installing the release.

Here's how I implement the event handlers in a column:

For some reason this has stopped working!  Any ideas on how to get it going again? Basically, the event specified doesn't fire at all.

Hi All,

I've been playing around with the themes and it seems straightforward. However, I do have one issue - whichever theme I use, I always get whatever text is in TextBlock as White. Without the theme, it's black. With the theme, it's white.

Something as simple as <TextBlock>Test123</TextBlock> gives me a white text. Any idea what am I missing?

Thank you,

yonadav
