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 :)

002.just-in-time (JIT) debugging instead of this dialog box.

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

Workaround: 

public partial class Form1 : Form

        InitializeComponent();

        radRichTextEditor1.RichTextBoxElement.FindReplaceDialog = new MyFindReplaceDialog();

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?

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)

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.MasterTemplate.EnableHierarchyFiltering = True
            radgvStockCount.UseScrollbarsInHierarchy = True

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.

Please refer to the following code snippet demonstrating how the comparer can be applied:

        public RadForm1()
        {
            InitializeComponent();
            this.radGridView1.EnableFiltering = true;
            this.radGridView1.ShowHeaderCellButtons = true;
            this.radGridView1.FilterPopupInitialized += radGridView1_FilterPopupInitialized; 
        }

        private void radGridView1_FilterPopupRequired(object sender, FilterPopupRequiredEventArgs e)
        {
            RadListFilterPopup popup = e.FilterPopup as RadListFilterPopup;
            if (popup != null)
            { 
                popup.MenuTreeElement.TreeView.TreeViewElement.Comparer = new MyComparer(popup.MenuTreeElement.TreeView.TreeViewElement);
            }
        }

        class MyComparer : TreeNodeComparer
        {
            public MyComparer(RadTreeViewElement treeView)
                : base(treeView)
            {
            }
            public override int Compare(RadTreeNode x, RadTreeNode y)
            {
                if (this.TreeViewElement.SortOrder == SortOrder.Descending)
                {
                    return x.Text.CompareTo(y.Text);
                }
                return x.Text.CompareTo(y.Text) * -1;
