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);
    }
}

To reproduce:

  doc.Pages[0].CropBox = new Rect(150, 150, doc.Pages[0].Size.Width - 30, doc.Pages[0].Size.Height - 30);

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

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

 

The exception bubbles up to the ViewFactory.ShowWebCam() method, but it doesn't get trapped by that method's try/catch or in your OnWebCamError event.

To reproduce (a bit random)

Im using a logitech HD C270, usb cam

There's often a period of initialization where the cam shows a white or black screen. Sometimes, pressing the control's capture button during this period causes the exception.

I reproduced it in the telerik Quick Start Framework, web cam app. The following code window is the stack trace of when it happened.

I understand that this is within Media Foundation code, and I'm guessing the capture is asynchronous, but is there any way that your control can catch the error as I know my users will be onto the support department when it happens?

Or is there any way to disable your embedded buttons until an image actually appears? I've tried trapping some paint events within the control but failed.

There's also no indication of what's happening during the initialization period, which has taken 10-20 secs occasionally, so it's very tempting to press those buttons :)

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

Workaround: 

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();

        radRichTextEditor1.RichTextBoxElement.FindReplaceDialog = new MyFindReplaceDialog();

    }
}
class MyFindReplaceDialog : FindReplaceDialog
{
    public MyFindReplaceDialog()
    {
        this.Controls[0].TabIndex = 2; // FindNext button
        this.Controls[1].TabIndex = 3; // Replace Button
        this.Controls[2].TabIndex = 5; // CloseButton
        this.Controls[3].TabIndex = 4; // Replace All button
        //this.Controls[4].TabIndex = 5; // label
        //this.Controls[5].TabIndex = 5; // label
        this.Controls[6].TabIndex = 1; // RepalceWith textbox
        this.Controls[7].TabIndex = 0; // TextToFind  textbox
         

    }
    protected override void OnShown(EventArgs e)
    {
        base.OnShown(e);
        this.Controls[7].Focus();
    }
}

Using FirstLook (also in my application) run the WebCam sample.

Press the takePhotoButton while running youtube video on 2nd monitor (also with netflix, so I assume it's general)

Sound on video pauses and returns when webcam control closed down.

Might be bug, or driver (Im using usb headphones) or needs me to set some property?

 

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. 

To reproduce:

- drop a track bar and make it less than 100 pixels, move the thumb to the right. 

Workaround:

 rtbPlaybackSpeed.TrackBarElement.MinSize = new System.Drawing.Size(0, 0);

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)

Add a combo-box column that point to a field with Guid data type, add summary item to this columns as well.

Workaround: 

private void RadGridView1_CreateRowInfo(object sender, GridViewCreateRowInfoEventArgs e)
{
    if (e.RowInfo is GridViewSearchRowInfo)
    {
        e.RowInfo = new MySerachRow(e.ViewInfo);
    }

}

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.

 

            radgvStockCount.DataSource = dtStockCountHeader
            radgvStockCount.MasterTemplate.EnableHierarchyFiltering = True
            radgvStockCount.UseScrollbarsInHierarchy = True
            radgvStockCount.MasterTemplate.Columns("INVCountHeaderId").IsVisible = False
            radgvStockCount.MasterTemplate.Columns("INVCountNo").HeaderText = "Stock Count No"
            radgvStockCount.MasterTemplate.Columns("CountryCode").HeaderText = "Country Code"
            radgvStockCount.MasterTemplate.Columns("AreaCode").HeaderText = "Area Code"
            radgvStockCount.MasterTemplate.Columns("LocationCode").HeaderText = "Location Code"
            radgvStockCount.MasterTemplate.Columns("LocationName").HeaderText = "Location Name"
            radgvStockCount.MasterTemplate.Columns("CreatedBy").HeaderText = "Opened By"
            radgvStockCount.MasterTemplate.Columns("CreatedDate").HeaderText = "Opened Date"

            Dim template As New GridViewTemplate()
            template.DataSource = dtStockCountBatches
            radgvStockCount.Templates.Add(template)
            template.Columns("INVCountBatchesId").IsVisible = False
            template.Columns("INVCountHeaderId").IsVisible = False
            template.Columns("INVCountNo").HeaderText = "Stock Count No"
            template.Columns("INVCountBatchesNo").HeaderText = "Stock Count Batch No"
            template.Columns("LocationCode").HeaderText = "Location Code"
            template.Columns("LocationName").HeaderText = "Location Name"
            template.Columns("SupervisorQty").HeaderText = "Supervisor Qty"
            template.Columns("CreatedBy").HeaderText = "Batch File Uploaded By"
            template.Columns("CreatedDate").HeaderText = "Uploaded Date"
            template.AllowAddNewRow = False
            template.AllowEditRow = False
            template.AllowDeleteRow = False
            template.AllowSearchRow = False
            template.AllowRowResize = False
            template.EnableFiltering = True
            template.EnableHierarchyFiltering = True
            template.ShowHeaderCellButtons = True
            template.ShowGroupedColumns = True
            template.EnableHierarchyFiltering = True
            template.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill

            Dim relation As New GridViewRelation(radgvStockCount.MasterTemplate, template)
            relation.RelationName = "StockCountBatches"
            relation.ParentColumnNames.Add("INVCountHeaderId")
            relation.ChildColumnNames.Add("INVCountHeaderId")
            radgvStockCount.Relations.Add(relation)

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.

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.

FIX. RadButton does not indicate that it is pressed when it is clicked with key instead of clicking with mouse

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)
    {
        //do your code here
        return base.Validate(stringValue);
    }
}

Use attached to reproduce.
