Release R2 2023 SP1

The error message appears when opening the custom option from the filter icon in RadGridView. 

The error message should not appear as there is a text in the textbox. When the enter key is pressed, the textbox value is still not committed which leads to this error. As a workaround, we can create a custom CompositeDataFilterForm override the ProcessCmdKey where we can handle this case.

public class MyCompositeDataFilterForm : CompositeDataFilterForm
{
    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        if(keyData == Keys.Enter)
        {
            this.Controls[2] as RadButton).Focus();
             (this.Controls[2] as RadButton).PerformClick();
        }
        return base.ProcessCmdKey(ref msg, keyData);
    }
}

private void RadGridView1_CreateCompositeFilterDialog(object sender, GridViewCreateCompositeFilterDialogEventArgs e)
{
    var newForm = new MyCompositeDataFilterForm();
    e.Dialog = newForm;
}

Release R3 2019 (LIB 2019.2.708)

When setting the DataFilter.Expression property to an expression that contains negative values, the DataFilter ignores that condition.

Please refer to the attached sample project.

Workaround:
FilterDescriptor fd = new FilterDescriptor("DescriptorItem1", FilterOperator.IsGreaterThan, -5);
this.radDataFilter1.DataFilterElement.AddChildNodes(fd, this.radDataFilter1.DataFilterElement.Nodes[0]);

Release R3 2021
To reproduce: I want to add multiple items to a filter expression using the Is in list operator.  It seems it is space delimited. For example, I want to filter for 'In Progress' and 'Late'.  However, when I apply the filter it creates this 'In', 'Progress', and 'Late'. 

Workaround: Currently, the possible solution that I can suggest is to use underscores to separate the words , e.g. "In_Progress".

To reproduce: set the DataSource property and enable the sorting for the fields drop-down items:

        Me.RadDataFilter1.SortOrder = SortOrder.Descending
        Me.RadDataFilter1.SortFieldNames = True

When you activate the drop-down editor to select a field name, you will notice that the items are always sorted ascending no matter the SortOrder.

Note: RadDataFilter should allow you to sort the drop-down items in descending order. 

Workaround:

    Private Sub RadForm1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        AddHandler Me.RadDataFilter1.EditorInitialized, AddressOf EditorInitialized
    End Sub

    Private Sub EditorInitialized(sender As Object, e As Telerik.WinControls.UI.TreeNodeEditorInitializedEventArgs)
        Dim editor As TreeViewDropDownListEditor = TryCast(e.Editor, TreeViewDropDownListEditor)
        If editor IsNot Nothing Then
            Dim element As BaseDropDownListEditorElement = TryCast(editor.EditorElement, BaseDropDownListEditorElement)
            element.ListElement.SortStyle = Telerik.WinControls.Enumerations.SortStyle.Descending           
        End If
    End Sub

Please refer to the attached screenshot illustrating what filter expressions and groups are added. As a result, an incorrect RadDataFilter.Expression is produced. RadDataFilter either must always contain a valid expression or indicates somehow when the current expression is not valid.
