Please refer to the attached sample project and follow the steps illustrated in the gif file.

Note: if the vertical  scrollbar is visible, the editor is activated as expected. 

Workaround:

Me.RadListView1.ItemSize = New Size(200, 30)

RadMaskedEditBox - (2019.3.903.40) - Text property not respecting numeric mask formatting on Up, Down keys

To repeat the bug create the RadMaskedEditBox and set the next properties:

this.radMaskedEditBox1.Mask = "N0";
this.radMaskedEditBox1.MaskType = MaskType.Numeric;

Enter the 111 in the editor. With the up/down keys set all of the values to 0.

Expected value is 0, got 000.

To reproduce: 

The tab order in the dialog is incorrect, the dialog is not focused when shown.

Workaround: 

To reproduce:
- Open the attached project.
- Type a text so there are no results in the drop down.
- Press Enter.
- Click the arrow button.

Workaround: 
private void RadMultiColumnComboBox1_DropDownOpened1(object sender, EventArgs e)
{
    if (radMultiColumnComboBox1.Text == "")
    {
        radMultiColumnComboBox1.EditorControl.FilterDescriptors.Clear();
        CompositeFilterDescriptor compositeFilter = new CompositeFilterDescriptor();
        compositeFilter.FilterDescriptors.Add(new FilterDescriptor("Drug", FilterOperator.StartsWith, ""));
        compositeFilter.FilterDescriptors.Add(new FilterDescriptor("Name", FilterOperator.StartsWith, ""));
        compositeFilter.LogicalOperator = FilterLogicalOperator.Or;
        radMultiColumnComboBox1.EditorControl.FilterDescriptors.Add(compositeFilter);
    }
}

Use attached to reproduce. 

- Click at least 7 times.

Workaround: Crete new series instance each time.

If you apply one theme to the entire application and want to apply another theme for RadDock as it is demonstrated in this help article, the ThemeName property of RadDock is not respected:

        public RadForm1()
        {
            InitializeComponent();

            radDock1.ElementTree.EnableApplicationThemeName = false;
            radDock1.ThemeName = "FluentDark"; 
            ThemeResolutionService.ApplicationThemeName = "Windows7"; 
        }

Please run the attached sample project with the latest version. You will notice that the maximized floating window is not loaded properly. This used to work in versions prior to R1 2019.

Workaround: remove "WindowState=Maximized" from the XML.

Add a RadSpreadsheet on the form and try resizing it at design time. You will notice that the control is resized after a considerable delay.

If you Dock the control to Fill and try resizing the form at run you will notice that the layout is incorrect. The attached gif file illustrates the obtained behavior.

Workaround: update the layout after resizing:

How to reproduce
public partial class Form1 : RadForm
{
    public Form1()
    {
        InitializeComponent();

        GridViewTextBoxColumn textBoxColumn = new GridViewTextBoxColumn();
        textBoxColumn.Name = "Column";
        textBoxColumn.HeaderText = "Column";
        this.radGridView1.MasterTemplate.Columns.Add(textBoxColumn);

        GridViewTextBoxColumn textBoxColumn2 = new GridViewTextBoxColumn();
        textBoxColumn2.Name = "TextBoxColumn2";
        textBoxColumn2.HeaderText = "ReadOnlyColumn";
        this.radGridView1.MasterTemplate.Columns.Add(textBoxColumn2);

        for (int i = 0; i < 10; i++)
        {
            object v = i * 2;
            if (i % 3 == 0)
            {
                v = null;
            }

            this.radGridView1.Rows.Add(new object[] { i, v });
        }

        this.radGridView1.MultiSelect = true;
        foreach (var row in this.radGridView1.Rows)
        {
            foreach (var cell in row.Cells)
            {
                GridViewCellInfo cellInfo = cell as GridViewCellInfo;
                if (cellInfo != null && cellInfo.RowInfo.Index % 3 == 0 && cellInfo.ColumnInfo.Index == 1)
                {
                    cellInfo.ReadOnly = true;
                }
            }
        }
    }

}

i am not able to run the Quickstart examples

when i opened the solution in visual studio and run it, its throwing the error application its throwing error as "FileNotFoundException: Could not find file 'C:\Users\rpeddala\AppData\Roaming\Telerik\WinForms\Examples\Analytics\config.xml"as shown below

When  you increase the SmallTickFrequency and use the TrackBarSnapModes.SnapToTicks, moving the thumb with the mouse should snap to the visible ticks. 

RadGridView can not change the current column (by using the IsCurrent of the desired column) in the CurrentColumnChanged event.

The issue exists in Fluent, Material, and Crystal themes.

To reproduce:

Create an MDI application and maximize the child form. 

The child form buttons are not styled. 

You need to press Tab twice to move to the next control when in popup editor.

Use attached to reproduce. 

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:

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.
