Hi!
When using CopyingCellClipboardContent the event is fired x3 times in each cell (once for each supported format). So if I have selected 5 cells the copy will trigger the event 15 times. Is there any kind of event for multiple copies?
Hi,
My team is trying to make an update from WinForms 2015.1.331 to the Latest 2024 Q1 Update 2024.1.130. Asked me for the comparison RadGridView component features until 2015 Q1 version(current) vs the rest of improvements/features from current to 2024 Q1 version. Is there a better way to get this comparision without scrolling through all releases and noting down the features and manually analyzing?
I doubt that this is an issue with the WinForms controls but I'll ask anyway in case anyone has experienced this problem (and I haven't found any solution searching the web). My project is MDI with seven child forms so far. After a few months of development I finally experienced a problem when I select several of my menu options (launch several child forms). It doesn't matter what the order I select the menu options; the third menu option, whichever option that happens to be, gets a System.NullReferenceException.
The code for each menu option is this pattern:
private
void
miDULAudit_Click(
object
sender, EventArgs e)
{
if
(objDULAudit ==
null
)
{
objDULAudit =
new
frmDULAudit();
objDULAudit.MdiParent =
this
;
objDULAudit.FormHiding +=
new
EventHandler(ChildFormHiding);
}
objDULAudit.Show();
objDULAudit.BringToFront();
objDULAudit.Activate();
objDULAudit.WindowState = FormWindowState.Maximized;
}
The error happens at objDULAudit.Show(); (in this code example).
System.NullReferenceException was unhandled
HResult=-2147467261
Message=Object reference not set to an instance of an object.
Source=System.Windows.Forms
StackTrace:
at System.Windows.Forms.NativeWindow.WindowClass.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)
InnerException:
I stepped through every line of code (as the child form instantiates) trying to run into the problem but I have not been successful.
Any ideas?
Thank you,
Gary
the data has been bind to radgirdview ,how to set the rowspan at runtime ? because must use set DataSource method to render data ,so cann't render the gridview cell by cell.
In the screen capture below I have a RadGridView in a RadCollapsiblePanel. I need to hide the border for both the CollapsiblePanel and the PanelContainer.
I tried the code below - which I found on another form post = but to no avail:
radCollapsiblePanel1.ControlsContainer.PanelContainer.BorderStyle = System.Windows.Forms.BorderStyle.None; radCollapsiblePanel1.ControlsContainer.PanelElement.Border.Visibility = ElementVisibility.Collapsed;
What am I doing wrong?
Thanks

Hello,
I am looking for a freelance GUI Designer familiar with Telerik UI for Winforms for an internal Project

I have a completely new winforms project. The only thing I adjusted was to change the target framework from .NET6 to .NET7 in the projects properties.
Now, each time I minimize (or maximize) a RadForm and then "normalize" it again, it is getting larger (some pixels to the right and to the bottom). This does not happen on .NET6 but on .NET7 and .NET8.
There is also an issue within the VS designer: When I open the form again its size is also slightly different (e.g. set to "300; 300" changed to "318; 243"). It also does not matter if I change the forms AutoScale value to "None", "Font", "DPI" or "Inherit". Furthermore, I have no strange scaling in MS Windows, it is set to 100 %.
What is the reason for this behaviour and what do I need to do to prevent it?
I would also like you to check if this occurs to other controls, as well.
Hi,
Is it possible to modify mp4 output settings to increase video quality?
Currently it seems to be fixed at around 4 mbps which results in poor quality for full hd.
Thanks

Is there a way to detect when the user clicks on the column header to sort.
An event like SortStarted and SortFinished?
I'd like to capture that event to perform some special processing.
