Hello,
I have quite complex object with joins and sub-queries to display on grid. Currently I'm getting only 1000 records from database to get better performance. I would really like to have benefits from grid filtering, sorting, server side virtualization, and paging to enable in rare cases uses to go through all data. However I didn't find any way or information how to to do that with complex select data. This data is currently collected 100% using Entity Framework. I've looked to use yours entity framework data source but it only allows simple usage - native entities not complex custom joins.

Could you advice me how to achieve that?

My event handlers do not get activated after moving to DragDropManager -- what to do?

Hi telerik,

I'm trying to make the move from 'old school' d'n'd to the new based on latest release. I've tried to follow you example in documentation.
However, no events are activated. The dragged item is moved to new location, completely handled by the treeview (and none of my code discovers it).

Any suggestions on what to do?

Thanks,

Anders

xaml:

<Controls:RadTreeView

ItemsSource="{Binding Path=WorkspaceViewModel.Children, NotifyOnSourceUpdated=True}"

Name="treeview"

IsLineEnabled="True"

MouseRightButtonDown="TreeviewMouseRightButtonDown"

IsDragDropEnabled="True"

SelectionMode="Single"

MouseLeftButtonDown="TreeviewMouseLeftButtonDown"

IsEditable="{Binding CommandHandlerViewModel.CanEditSelected}"

ItemEditTemplate="{StaticResource edittemplate}"

>

<Controls:RadTreeView.Resources>

<Style TargetType="Controls:RadTreeView">

<Setter Property="telerik:DragDropManager.AllowCapturedDrag" Value="True"></Setter>

</Style>

</Controls:RadTreeView.Resources>

In the constructor of the usercontrol, holding the treeview:

DragDropManager.AddDragInitializeHandler(treeview, OnDragInitialize);

DragDropManager.AddGiveFeedbackHandler(treeview, OnGiveFeedback1);

DragDropManager.AddDragDropCompletedHandler(treeview, OnDragCompleted1);

DragDropManager.AddDropHandler(treeview, OnDrop1);

None of them are implemented yet -- I'm expecting an exception:

private void OnDragCompleted1(object sender, DragDropCompletedEventArgs e)

{

throw new NotImplementedException();

}

private void OnDrop1(object sender, Telerik.Windows.DragDrop.DragEventArgs e)

{

throw new NotImplementedException();

}

private void OnGiveFeedback1(object sender, GiveFeedbackEventArgs e)

{

throw new NotImplementedException();

}

private void OnDragInitialize(object sender, DragInitializeEventArgs e)

{

throw new NotImplementedException();

}

GridViewGroupRow TargetType does not match type of element GroupHeaderRow

RadGridView supports only unique hashcodes

I am using an editable RadGridView to present a collection of items of a class, which overrides the GetHashCode method in a way that hash codes are not unique. The problem is that in such a case changing property values from code is not reflected in grid cells. The problem is gone when hash codes are unique.

I found a forum post from 2011 which says that GridView does not support items with non-unique hash codes.
My question is: Has it been fixed already? Is it planned to be fixed?
I perceive it as a bug, having in mind a rule that equal items have the same hashes, but equal hashes don't determine that objects are the same. I think that the grid should handle items with the same hash code properly.

---------------------------------------------------------------------------------------------------------

Some more details about my problem:

I simplified my class to the following one:

public class Entry : PropertyChangedBase

{

private string name;

public string Name

{

get

{

return this.name;

}

set

{

this.name = value;

this.NotifyOfPropertyChange(() => this.Name);

this.description = "new content of a description cell";

this.NotifyOfPropertyChange(() => this.Description);

}

private string description;

public string Description

{

get

{

return this.description;

}

set

{

this.description = value;

this.NotifyOfPropertyChange(() => this.Description);

}

public override int GetHashCode()

{

return 145;

}

So behaviour of this class is the following:
- changing the Name column should also change the Description column
- hashcodes for multiple items may be the same

However, a grid which is bound to a collection of such items doesn't work as expected. After editing a Name column, the Description property gets updated, but the change is not visible in the grid. The Description cell gets updated only when I click on the cell and open its editor.

Auto hide RadPane problem on 2 monitors

I use version: 2012_3_1129

There is an issue with docking control on 2 monitors. I have RadPane docked at the bottom and I turn on "Auto hide" option, so this pane hides.
The issue occurs when I my application window is wider than my first monitor and more than 50% is on the first monitor. In this case when I want to show my pane (docked bottom) which is hidden than it appears only on the first monitor and the part which should be present on the second monitor is not visible (right "x" button is not visible on that pane).

removing unwanted behavior in RadMaskedNumericInput

Hi There,

we dont want to use the below features of RadMaskedNumericInput

if we enter some digits in middle of the numeric value, the right side digits are overriding(in our case it should not override and should not allow the user to type any thing but to change the digit he can select the required digit/range and type to change)

Is it possible to change this behavior by overriding any thing ?

Regards,
Srinivas.
