Release R3 2019

Please refer to the attached sample project and run it. Select a random item and press the button. You will obtain the error. If no selection is available, the item is removed as expected. 

Workaround: use Begin/EndUpdate block while deleting a record from the DataTable:

        Me.RadGanttView1.BeginUpdate()
        _dataset.Tables("Tasks").Rows.RemoveAt(2)
        Me.RadGanttView1.EndUpdate()

To reproduce: 

Change the scaling to 200% or larger.

Set the animation:

 this.commandBarToggleButton1.UseDefaultDisabledPaint = true;
 this.commandBarToggleButton1.Enabled = false;

Hello,

In our Environment it's not possible to assign a GroupComparer to another GridView template then MasterTemplate. The GroupComparer property is always null after assignment.

It's possible to assign our custom comparer to the MasterTemplate and it will be triggered, but not in another template then MasterTemplate.

Best regards.

Maybe I'm doing this wrong but it works with the standard .Net SaveFileDialog. No matter how many filters I add or which FilterIndex I set, the last filter is always activated.

With DF.RadSaveFileDialog1
    .SaveFileDialogForm.StartPosition = FormStartPosition.CenterParent
    .SaveFileDialogForm.Text = "Save File As - " & DF.OriginalTitle
    .SaveFileDialogForm.ThemeName = "Fluent"
    .CustomPlaces.Clear()
    .ShowNetworkLocations = False
    .InitialDirectory = My.Application.Info.DirectoryPath()
    .Filter = "Word Document (*.docx)|*.docx|PDF Document (*.pdf)|*.pdf"
    .RestoreDirectory = True
    .FilterIndex = 1
    .ShowDialog()
End With

Using a custom control using the Telerik Presentation Framework, I am receiving a NullException inside the GridCheckBoxHeaderCellElement during the GridViewElement's data load.

The custom control construction follows an example I found somewhere (reference is lost to me at this point):

ControlContainingGridView inherits from RadControl

CreateChildItems creates and adds ControlContainingGridViewElement

 

ControlContainingGridViewElement inherits from RadElement

CreateChildItems creates and adds some layout controls AND a GridViewElement

 

public partial class ControlContainingGridView : RadControl {
        public ControlContainingGridView() {
            InitializeComponent();
            this.TextChanged += ControlContainingGridView_TextChanged;
        }

        private void ControlContainingGridView_TextChanged(object sender, EventArgs e) {
            controlContainingGridViewElement.Text = this.Text;
        }

        private ControlContainingGridViewElement controlContainingGridViewElement = null;


        protected override void CreateChildItems(RadElement parent) {
            controlContainingGridViewElement = new ControlContainingGridViewElement();
            this.RootElement.Children.Add(controlContainingGridViewElement);
            base.CreateChildItems(parent);
        }

        public object DataSource {
            get {
                return controlContainingGridViewElement.GridView.Template.DataSource;
            }
            set {
                try {
                    controlContainingGridViewElement.GridView.Template.DataSource = value;
                } catch (Exception ex) {
                    Debug.WriteLine(ex);
                }
            }
        }

        internal void SetupColumns(Action<MasterGridViewTemplate> setupColumns) {
            controlContainingGridViewElement.GridView.Template.AutoGenerateColumns = false;
            setupColumns(controlContainingGridViewElement.GridView.Template);
        }



    }

            dlp.StretchHorizontally = true;

            };

            this.Children.Add(dlp);
            base.CreateChildElements();
        }

    }

 

During Form load, I programmatically add columns and provide a binding source

 

private List<SampleModel> sampleModels = new List<SampleModel>();
        private BindingSource sampleModelsBinding = new BindingSource();

        private void RadForm1_Load(object sender, EventArgs e) {

            sampleModels.Add(new SampleModel() {
                When = DateTime.Parse("1980-04-23"),
                SomeText = "Purple Bananas",
                IsTrue = true
            });
            sampleModels.Add(new SampleModel() {
                When = DateTime.Parse("2002-07-20"),
                SomeText = "Ball & Chain",
                IsTrue = false
            });
            sampleModelsBinding.DataSource = sampleModels;

            controlContainingGridView.SetupColumns((grid) => {
                grid.AddDateTimeColumn(nameof(SampleModel.When), "When");
                grid.AddTextBoxColumn(nameof(SampleModel.SomeText), "Some Text");
                grid.AddCheckBoxColumn(nameof(SampleModel.IsTrue), "Is True");
            });

            controlContainingGridView.DataSource = sampleModelsBinding;

        }
