I'm a Progress OpenEdge developer and found issue with RadGridView using it in a ABL application. I have been able to reproduce the issue outside of the OpenEdge environment, and have attached a project file.

 

To see the issue, run the app, and scroll down really quickly with scrollbar thumb to the bottom.

You will then get:

System.NullReferenceException
  HResult=0x80004003
  Message=Object reference not set to an instance of an object.
  Source=Telerik.WinControls.GridView
  StackTrace:

/////////////////////////////////////////////////////////////////////////////////////////////////

The following notes will explain what we are doing, since it may not be typical.

 

The MaxDataGuess functionality offers a time-saving alternative for the OpenEdge BindingSource that binds to a query with 
a very large result set. 
Some .NET controls must know the number of records in the result set when they initialize. 
By default, the ProBindingSource counts the records by reading the records in the query's result set, which can be time-consuming for large 
result sets. Setting this property provides the .NET control with an estimated value to bypass the counting process.
Sometimes, the result list can contain tens of thousands records, so this functionality would be used for that use case.


The project that demonstrates the issue found with the Telerik GridView is a much simpler version of the actual OpenEdge implementation.
The Progress.Data.DataSource._actualNumberOfRecords property is just a hard coded value that takes the place of the ABL query result set list,
since this project does not include the OpenEdge specific code.

The internal implementation of the MaxDataGuess in this project is as follows:

The DataSource.Count property is originally set to 50.
See Form1.cs:  pbs = new Progress.Data.BindingSource(myDataTable, maxDataGuess);


Once user scrolls through rows close to the Count property,  the routine CheckForOffEnd() is called 
(triggered by IDataErrorInfo.Error property).
If it determines that we are close to "current" end of rows, it adds 100 more rows calling
OnListChanged(new ListChangedEventArgs(ListChangedType.ItemAdded, ix));
to notify the grid control that we've update the Count property.

The routine FillCacheFromPVMSource() is called to fill in the CacheRow param for the specified rowIx.
The exception comes into play when the rowIx is greater than the current Count property.
If this is the case, then FillCacheFromPVMSource() updates the Count property, and also calls
OnListChanged(new ListChangedEventArgs(ListChangedType.ItemDeleted, ix));
when adjusting the Count property to notify the Telerik grid.

The exception occurs when control passes back to the Telerik code. 
The rowIx is no longer valid, and the Telerik grid does not check for this.


We get the following System.NullReferenceException:

'Object reference not set to an instance of an object.'

I noticed a weird issue with the RadTextBoxControl when using a combination of word wrap and multiline.

If the text that is being wrapped is too close to the edge of the control, the selection highlight renders incorrectly.

Here is an example:

I have attached a sample to reproduce the issue.

To reproduce:

        ThemeResolutionService.ApplicationThemeName = "Windows11"

        Dim UserGroup As New DescriptionTextListDataItem
        With UserGroup
            .Text = "Admins"
            '.Font = New Font("Microsoft Sans Serif", 9.75, FontStyle.Bold)
            .DescriptionText = "System Administrations Group"
        End With
        Me.RadListControl1.Items.Add(UserGroup)
        Me.RadListControl1.ItemHeight = 50

Actual result:

Use attached to reproduce:
- Disable and then enable the RadSateTimePicker
- You will notice that even the checkbox is unchecked the control is enabled. 

Workaround:

radDateTimePicker1.Enabled =true;
if (!radDateTimePicker1.DateTimePickerElement.Checked)
{
    radDateTimePicker1.DateTimePickerElement.TextBoxElement.TextBoxItem.HostedControl.Enabled = false;
}

To reproduce:
            this.radDropDownList1.DropDownListElement.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
            this.radDropDownList1.DropDownListElement.AutoCompleteAppend.LimitToList = true;
            this.radDropDownList1.DataSource = new List<string>() { "Test1", "Test2" };

Copy "Test2" and right click over the textbox. The second item is selected. However, if you press Ctrl+V instead of using the Paste option in the context menu, nothing happens.

Workaround:

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        RadDropDownList1.DropDownListElement.AutoCompleteMode = AutoCompleteMode.SuggestAppend
        RadDropDownList1.DropDownListElement.AutoCompleteAppend.LimitToList = True
        RadDropDownList1.DataSource = {"Test1", "Test2"}
        
        Me.RadDropDownList1.DropDownListElement.AutoCompleteAppend = New CustomAutoCompleteAppendHelper(Me.RadDropDownList1.DropDownListElement)

To reproduce:
- Add some rows to a grid.
- Sort the rows.
- Delete a row.
- The current row is not the next row.

Workaround:
Dim t As Test = RadGridView1.CurrentRow.DataBoundItem
Dim index As Integer = Me.RadGridView1.ChildRows.IndexOf(Me.RadGridView1.CurrentRow)
datasource.Remove(t)
Me.RadGridView1.CurrentRow = Me.RadGridView1.ChildRows(index)

To reproduce: 
1. Use the following code snippet:
public class ViewModel:INotifyPropertyChanged
{
    public ViewModel()
    {
    }

    private bool _isShown;

    public bool IsShown
    {
        get
        {
            return this._isShown;
        }
        set
        {
            this._isShown = value;
            OnPropertyChanged("IsShown");
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected void OnPropertyChanged(string propertyName)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
            handler(this, new PropertyChangedEventArgs(propertyName));
    }
}

2. Add a MS Panel and a RadPanel to the form.
3. Add Panel.DataBindings at design time for its Visible property to the ViewModel.IsShown property.
4. When you run the application, the MS Panel is not visible. However, if you remove the RadPanel it is shown. Please refer to the attached sample video illustrtaing better the performed steps.

2. Focus the spin editor again and enter 5. Navigate to the next control. The NullableValueChanged event is fired as expected.

3. Focus again the spin editor, select the text and press Del. Navigate to the next control. The NullableValueChanged event is fired again as expected.

4. Focus again the spin editor and enter 0. Navigate to the next control. You will notice that the NullableValueChanged event is fired.

5. Focus again the spin editor, select the text and press Del. Navigate to the next control. The NullableValueChanged event is fired again as expected.

6. Focus again the spin editor and enter 0. Navigate to the next control. You will notice that the NullableValueChanged event is NOT fired in this case.

Hi

Please find attached sample project having 2 different reference folder(Telerik2018,Telerik2020) for Telerik.

Code flow & Issue description: I have Event "radGridView1_EditorRequired" in which i have attached another event on value changed "Editor_ValueChanged" in which we get data gron DropdownListElement using ((RadDropDownListElement)(sender)).SelectedValue.
Issue is when we use version (2018.3.1016.40) we get selected value text, in case of current version (2020.1.218.40) we get null value.

Current version DLL  2020.1.218.40 (Issue in current version)
Previous version DLL 2018.3.1016.40 (Working fine)

Note : I have also attached both version of Telerik DLL in sample project, you can reproduce issue by referencing to 2020.1.218.40 version. After selecting values as shown in attached screenshot you will get null value as shown in another screenshot.

Please find attached screenshot  for selecting values to reproduce issue as well where we get null value.

 

Thanks and Regards

When I select items 1 through 4 in the drop-down list, the expected event occurs (the selected item is removed from the drop-down list and added to the list view).  When I select the last item in the list (item 5), the item is added to the list and then I get the ArgumentOutOfRangeException.
