Wasnt there supposed to be a WPF book control also in the Q3 release ?

Hi, I have a question , I need to move the scroll into a possition in the row  where was selected, this is my code

                                           rgvPatients.SelectedItem = rgvPatients.Items[contRowsPatients];
                                            rgvPatients.ScrollIntoView(rgvPatients.SelectedItem);
                                            rgvPatients.UpdateLayout();

but never update the vertical scroll

Hi,

.xaml Code:

<

 

telerik:RadCarousel x:Name="rdcTasks" AutoGenerateDataPresenters="False" telerik:StyleManager.Theme="Office_Black" Margin="0,227,0,6" SelectionChanged="rdcTasks_SelectionChanged" Height="179" VerticalAlignment="Bottom" Loaded="rdcTasks_Loaded"></telerik:RadCarousel>

.net code:

 

foreach

 

(TaskQueryService.task objTask in objTasks)  

 

 

this.rdcTasks.Items.Add(objTask);

As the the number of items in the datasource is 4, the control doesnt display any data on the screen. I have to scroll to get the stuff displayed. where as if the items are 8 or more the items are displayed. I have another control with same properties set and its working. (dataitems are 49).

Please reply.

Hello,

I have a grid connected to a DataView. The DataView has a rowfilter.

I add lines to the DataView by code.

The problem is that if I enter into a cell, change its value and press on Tab, the cell somehow keeps focus (the cell's text is aligned to

the center and pressing on Tab keeps the align to the right of the cell).

This also has a weird effect on that specific row- it disregards the DataView filter.

This does not happen if I input a value to the cell and then move the focus to another cell by

clicking on it and not by the Tab key.

Thanks,

Erez

Is there a way to restart the animation that is shown when a chart initially builds?  In other words, on demand animating of the chart?

Thanks

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
