Now it is working fine with simple grid, but when I am trying to implement it on Hierarchy of grid then problem is there. For create hierarchy of grid I have used bellow direction.

 

Declare it on page Load

//For Hierarchy of grid

this.gridLesson.TableDefinition.PreviewDataRecordCreate += this.MasterTableDefinition_PreviewDataRowCreate;

 

Now Create “MasterTableDefinition_PreviewDataRowCreate” event.

 

//Hierarchy Grid Load

        private void MasterTableDefinition_PreviewDataRowCreate(object sender, DataRecordCreateEventArgs e)

        {

            e.IsExpandableRecord = true;

            GridViewTableDefinition detailDefinition = new GridViewTableDefinition();

            detailDefinition.Relation = new PropertyRelation("Files");

            e.ChildTableDefinitions.Add(detailDefinition);

 

        }

 

Can you help me for Grid Row Drag and Drop on that sitution.

 

Thanks,

Manas

Hi Manas,

It is actually quite difficult to figure out what has gone wrong without more information. Nevertheless, I am sending you an updated version of the original files in rowdragdrop.zip. GridViewRowDragDropManager now works better with hiearachy and also the ReorderRequestedEventArgs provides more information that can be useful in hierarchy scenerios.

Could you try to inforporate the updated files in your solution and see if the problems that you have reported are fixed. If not, may I ask oyu to send us your application so that we can take a closer look at the problem? You can send us files by opening a support ticket.

Hope this helps.

Hi Milan,
I am not getting any link for updated version of the original files in rowdragdrop.zip. I hope, that would be very helpful for me.
kindly send me  updated version of the original files in rowdragdrop.zip link.


Thanks,
Manas

Hello Manas,

Here is the updated project that I have promised. Only two files are changed (GridViewRowDragDropManager.cs and ReorderRequestedEventArgs.cs) and one new file is added (GridViewRowExtensions.cs).
Sorry for the inconvenience.

May you give me details about support ticket, so I can upload my project to close look. There are still issue to configure your Grid Row drag and Drop Code into my hierarcy Grid.

Thanks for your excellent support.

Thanks Milan,

 

Now Grid row drag and drop is working fine with hierarchy grid. But I am facing another problem, that is we have applied custom row style link  RowStyle="{StaticResource CustomRowStyle}" on Grid then I cannot select any row to copy paste from Excel, which one was working previously.

 

May you help regarding that quickly?

 

Regards,

Manas

[Milan]

Hello Manas,

Unfortunately the copy to clipboard functionality only works for the WPF version of RadGridView due to limitations of the Silverlight plugin.
Sorry for this inconvenience.

Sorry for little misunderstanding here, already I have developed Copy to Clipart from RadGridView in Silver light and paste also, now problem is when I have applied Row Style (RowStyle="{StaticResource CustomRowStyle}") on Hierarchical RadGridView for Drag and Drop Row within Grid then I can’t select a full row.

 

So, right now I can’t select full row to copy paste. I hope, now you can understand, what my goal is.

 

Regards,

Manas

Hello Manas,

The selection mechanism should be working. If you take a look at the SelectedItems collection you will see that items are indeed selected. The actual problem is that the custom style does not include visual styles that respond to the different row states. I am sending you the style and template of GridViewRow as a reference.

Just a quick reminder - whenever you select an item in a child grid this selection will not be reflected in the SelectedItems of the parent grid but only in the SelectedItems of the child grid itself. 

Sincerely yours,
Milan

These drag-drop solutions are helpful, thanks! However, they all rely on casting the GridViewRow to a DataRecord, which is now deprecated (and missing from 2009 Q3), to get the row index within the grid.

Since DataRecord is going away, what's the best way to get the row index?

[Vlad]

Hi Patrick,

You can use Items property to get desired data item index.

So, something like

idx = gridView.Items.IndexOf(aRow);

Not working for me either, I'm afraid.

[Vlad]

Hi Patrick,

if aRow is some of your business objects there should be no problems.

Thanks Vlad, that makes sense. This is in the context of GridViewRowDragDropManager.ParentControl_MouseUp() as posted by Milan in the rowdragdrop2.zip project on May 29, that is what I'm working with. So to get the dragged row's index, I can do

 

 

oldIndex = gridView.Items.IndexOf(originalRow.DataItem);

which works nicely. Thanks!

Hi Vlad,

I have experimented with your example of moving rows within a GridView and it all works fantastically.

My question is, will this ever be provided OOB by the GridView in a future release?

There is a lot of boiler plate code involved in your example that ideally should be abstracted outside of my application (like how DragDrop works).

Kind regards,
James.

[Vlad]

Hello James,

Since now our Drag & Drop framework is available for both Silverlight and WPF this is preferred way. Please check this demo for more info:

Hi,
    I have a particular requirement wherein I have a Radgridview which is populated with some data and each row has a button. Now on click of this button I want to select the corresponding row of the RadGridView and iterate through each cell.

Thanks,
Tejas

[Vlad]

Hello,

You can get the row from the button click event handler using our powerful extension methods:

var row = ((Button)sender).ParentOfType<GridViewRow>();

Could I get the example of changing order of rows by dragging, if implementation is different, of the functionality posted May 22, 2009. In WPF and with the Q3 SP1 Controls.

Scott

[Tsvyatko]

Hi Scott Christian,

Using Q3 SP1 allows you to achieve similar functionality using DragDrop manager. Attached you will find sample WPF application demonstrating row reorder using DragDrop Manager.

For more information about RadDragDrop Manager you can check your Examples and Documentation.

Hope this helps.

Hi,

Can I get this example but for Silverlight 4 / Telerik 2010.2.0714.1040?
The WPF example has SL unusable code
 

GridViewRow row = this.GetRowFromHitTest(this.RadGridView, e.Options.CurrentDragPoint);
HitTestResult result = VisualTreeHelper.HitTest(subTree, intesectionPoint);


Thanks,

Ray
