This way the column could bind to any collection of objects which can be converted to doubles.

When you set the AutoSize property to true, the control becomes enormous - Size (5002, 5002).

There is no specific logic for auto-sizing the control. We should either remove the AutoSize property or size the control according to the rows/columns it uses.

Dear Telerik Support Team,

 

I have a Grid with one level of Hierarchy, I am using also the search row control of Gridview but this control only searches the data in the Parent Grid and not in the child Grid, I am using the version: v.2019.2.618.20 of Telerik controls in the Project. Below is the code snippet which is used in the Project, please let us know how we can search in child grid using the search row of the Gridview.

When pressing Enter or Tab in the new row the ParsingDateTime event is fired after the editor is validated. Use attached to reproduce.

 

private void GridView_CellEditorInitialized(object sender, GridViewCellEventArgs e)
{
    var editor = gridView.ActiveEditor as RadDateTimeEditor;
    var editorElement = editor.EditorElement as RadDateTimeEditorElement;
    editorElement.TextBoxElement.MaskType = MaskType.FreeFormDateTime;
    var provider = ((FreeFormDateTimeProvider)editorElement.TextBoxElement.Provider);
    editorElement.TextBoxElement.Provider = new MyFreeFormDateTimeProvider(provider.Mask, provider.Culture, provider.Owner);
}

class MyFreeFormDateTimeProvider : FreeFormDateTimeProvider
{
    public MyFreeFormDateTimeProvider(string mask, CultureInfo culture, RadMaskedEditBoxElement owner) : base(mask, culture, owner)

    }
    public override bool Validate(string stringValue)

Run the attached sample project and select the second page. You will notice that the tasks are missing. This used to work in R2 2019 (version 2019.2.508).

Workaround: Initialize the RadGanttView.BindingContext before adding it to the page:

        Dim Gantt As New RadGanttView
        Gantt.Dock = DockStyle.Fill
        Gantt.BindingContext = New BindingContext()
        RadPageViewPage2.Controls.Add(Gantt)

We have upgraded from WinControl UI 2010 to 2019 R2. 

we have a lot of non-data bound radgridview that we process our data and add each row manually.

The radgridView.Rows.Add(rowdatacolumn1, rowdatacolumn2, rowdatacolumn3) used to return the row index of the added row. It is now returning -1 . 

This is breaking a lot of our code.

I've got a tree with multiple nodes like

document1

 -page 1 

  -page 2

document1

 -page 1 

  -page 2

  -page 3

...

document10

 -page 1 

  -page 2

Due to the size of the treeview, only 2 or 3 documents are on screen, the rest is scrolled. (manually added items, no dynamic or lazy loading)

Lets say I click page 2 of document one, hold the mouse button to select more and go down to the last document (the tree is automatically scrolled down, as expected)

But when I go back to review what I selected, only the last items on screen are selected (documents 9 and 10 for example).

When I try to do the same selection with the arrow keys and the shift key, it works fine, but not with the mouse.

The DateTime Value is lost when using a custom format "dd.MM.yyyy" in RadgridView and custom provider is used. 

Workaround: 
Set the MaxDate in the custom provider:
Public Class MyMaskDateTimeProvider
  Inherits MaskDateTimeProvider

  Public Sub New(mask As String, culture As CultureInfo, owner As RadMaskedEditBoxElement)
        MyBase.New(mask, culture, owner)
        Me.MaxDate = DateTime.MaxValue
    End Sub

        With RadDateTimePicker1

Please use the following code snippet to setup the Gantt view:

Sub New()

                 


        InitializeComponent()

        Dim dt As New DataTable
        dt.Columns.Add("ID", GetType(Integer))
        dt.Columns.Add("Group_ID", GetType(Integer))
        dt.Columns.Add("Title", GetType(String))
        dt.Columns.Add("Start", GetType(DateTime))
        dt.Columns.Add("End", GetType(DateTime))

        dt.Rows.Add(-999, 0, "Root", New DateTime(2019, 8, 21), New DateTime(2019, 8, 30))
        dt.Rows.Add(6, -999, "Item 1", New DateTime(2019, 8, 21), New DateTime(2019, 8, 23))
        dt.Rows.Add(7, -999, "Item 2", New DateTime(2019, 8, 26), New DateTime(2019, 8, 30))
        dt.Rows.Add(1000, 6, "Sub1.1", New DateTime(2019, 8, 21), New DateTime(2019, 8, 22))
        dt.Rows.Add(1001, 6, "Sub1.2", New DateTime(2019, 8, 22), New DateTime(2019, 8, 23))
        dt.Rows.Add(1002, 6, "Sub1.3", New DateTime(2019, 8, 23), New DateTime(2019, 8, 23))
        dt.Rows.Add(1003, 7, "Sub2.1", New DateTime(2019, 8, 26), New DateTime(2019, 8, 29))

        Me.RadGanttView1.GanttViewElement.GraphicalViewElement.TimelineStart = New DateTime(2019, 8, 20)

However, if you switch the order of adding the rows, not all items will be visible in RadGanttView:
