Good morning,
I would like to ask three questions concerning your radWebCam control.
1. We're using it within an application running on a Windows 10 tablet and I would like to ask if it's possible to move the control panel to the left or right side to have it vertical? As our tablet is pretty heavy (it's a Dell Latitude 7212 for rough environments), the usability of our app would improve a lot if our workers could keep their tablet in both hands while taking a photo.
2. Regarding the use on a tablet, I wanted to enlarge the control panel of the camera as well as the buttons on it. I noticed a kind of strange behaviour when I change the Control Panel Height via the smart tag. As soon as I modify this value to something else than 30, the camera doesn't launch anymore and VS 2019 says, that the application is in break mode due tu a System.InvalidOperationException that was thrown within External Code. Is that maybe related to the video format or to other parameters that I set when launching the camera? I attached you my demo project, you can download it here: https://easyupload.io/la69am
3. We would like to add a button to swap the camera (front and back). I just dragged a radButton with this functionality onto the control panel of the webcam and anchored it to the bottom. It works fine but the only problem which is left is that I would like to disable or hide this button when the user took a picture and has the choice of saving or discarding it. The event "SnapshotTaken" is fired only after clicking on the disc to save the snapshot. But how can I "catch" this state of the photo preview before saving it?
Thank you in advance for your help and have a nice day!

RadMemnuItems have a .showArrow propery, which shows a little triangle to the right of the item, to indiate there are sub-items.
Does anyone know how to make the arrow appear at the bottom of the item? There 's Direction property, but that changes where the wrrow points, which is useful, but does not change its position.

Is it possible to send mail report from RadGridView Telerik WinForms C#. I have button to print when the button is clicked the report should export to pdf also.

Hi,
I'd like to customize the location of a MessageBox. Ideally, I would just set a parent control and the MessageBox would center itself to the parent.
I tried this ((0,0) to make it obvious) but it doesn't work:
'Dim pt As Point = New Point(Me.Parent.Location.X + Me.Location.X, Me.Parent.Location.Y + Me.Location.Y)
'Telerik.WinControls.RadMessageBox.Instance.Location = New Point((pt.X + Me.Width / 2) - (Telerik.WinControls.RadMessageBox.Instance.Width / 2), (pt.Y + Me.Height / 2))
Telerik.WinControls.RadMessageBox.Instance.Location = New Point(0, 0)
Dim ds As DialogResult = Telerik.WinControls.RadMessageBox.Show(Me, "Are you sure?", "Clear form",
MessageBoxButtons.YesNo, RadMessageIcon.Question,
MessageBoxDefaultButton.Button1)I've also found this bit of code (modified it according to my needs) from an older answer to someone else's similar question:
Private Sub Instance_LocationChanged(sender As Object, e As EventArgs)
RemoveHandler RadMessageBox.Instance.LocationChanged, AddressOf Instance_LocationChanged
Dim box As RadMessageBoxForm = sender
Dim pt As Point = New Point(Me.Parent.Location.X + Me.Location.X, Me.Parent.Location.Y + Me.Location.Y)
box.Location = New Point((pt.X + Me.Width / 2) - (box.Width / 2), (pt.Y + Me.Height / 2))
AddHandler RadMessageBox.Instance.LocationChanged, AddressOf Instance_LocationChanged
End SubBut the problem here is that the MessageBox is then static and can't be moved.
Suggestions?
Using version 2021.1.326.40.

Hello,
I am using the RadSpreadProcessing library to create Excel reports: https://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/overview
I'm using the DataValidation (i.e. ListDataValidationRule) to create dropdowns with a set of values: https://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/data-validation
Here's the issue I'm seeing:
I go to try to create a dropdown with the ListDataValidationRule object, but when my string length is >255 characters for the Argument1 property and I export out the report, I receive an error when trying to launch the exported file:
Sample code:
CellIndex dataValidationRuleCellIndex = new CellIndex(0, 0);
ListDataValidationRuleContext context = new ListDataValidationRuleContext(worksheet, dataValidationRuleCellIndex);
context.ErrorStyle = ErrorStyle.Stop;
context.ErrorAlertTitle = "Wrong value";
context.ErrorAlertContent = "The entered value is not valid";
context.InCellDropdown = true;
context.IgnoreBlank= false;
// Insert string length is > 255 characters
context.Argument1 = <INSERT STRING OF LENGTH > 255 CHARACTERS>;
ListDataValidationRule rule = new ListDataValidationRule(context);
worksheet.Cells[dataValidationRuleCellIndex].SetDataValidationRule(rule);

Hi, How do I go about setting my own image for the help button shown in the title bar at run-time of a RadForm ? I can get the '?' button up but I want to change this form something else.
Thanks Toby

How can I put one Image on the right side of RibbonBar?

Hi guys,
I would like to get the 4 coordinates for the displayed map on RadMap
Top Right (x, y) , Top Left (x, y) , Bottom Left (x, y) , Bottom Right (x, y)
those values should change different when a user zoom in/out, or move the map with mouse.
is there a way to do that?
