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.

ScheduleView Style

Hi all,
i'm trying to custom style my ScheduleView after migrating from Scheduler, its suppose to look the same as the Scheduler did(pictures attached).
I tried taking an already made Theme from your Themes.Implicit folder but i can't find the right parts to change, i need pointers to the right parts(their names/their styles names) in order to modify it properly(the file is huge and i can't find anything in there).

Best Regards,
Jonathan Bacalo

GridViewDataColumn DataType not sorting correctly

I have a gridview that is built from a collection of records. I set the datatype of each column, and I can confirm that the datatype is correct in the gridview itself (by checking in debug). That being said, when I sort on certain numeric type columns - the grid is treating it as a string. Am I missing some kind of property? Here is my code.

var columns = mainViewModel.Records.First()

.Properties

.Select((x, i) => new { Name = x.Name, DataType = x.DataType, Index = i })

.ToArray();

foreach (var column in columns)

{

var binding = new Binding(string.Format("Properties[{0}].Value", column.Index));

GridViewDataColumn col = new GridViewDataColumn();

col.UniqueName = column.Name;

col.Header = column.Name;

col.DataMemberBinding = binding;

col.DataType = column.DataType;
