RadControls are slow when using at design time in a form containing a lot of controls, split containers and table layout panels
Workaround: manually resize the editor or drag it upwards
To reproduce: - Add RadLayoutControl to a form. - Change the Language property at design time. - You will receive the following message: There is already a command handler for the menu command '1496a755-94de-11d0-8c3f-00c04fc2aae2 : 103'. Workaround: - Reopen the designer.
Project Update Utility throws unhandled exception when you try to upgrade project which files are not checked-out from source control.
To reproduce: run the sample project, open the test.rtf file and start scrolling with the mouse. As a result, you will encounter the following error: ************** Exception Text ************** System.ArgumentException: Parameter is not valid. at System.Drawing.Image.get_RawFormat() at

To reproduce: add a RadLabel and change its cursor to Hand. this.radLabel1.Cursor = Cursors.Hand; The PixelatedHandCursor.png shows the poor quality of the cursor which should be improved. Workaround: https://stackoverflow.com/questions/6016995/un-antialiased-hand-cursor-in-windows-forms-apps/6017174#6017174 public class LinkLabelEx : RadLabel { private const int WM_SETCURSOR = 0x0020; private const int IDC_HAND = 32649; [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)] private static extern IntPtr LoadCursor(IntPtr hInstance, int lpCursorName); [DllImport("user32.dll", CharSet = CharSet.Auto)] private static extern IntPtr SetCursor(IntPtr hCursor); protected override void WndProc(ref Message m) { if (m.Msg == WM_SETCURSOR) { // Set the cursor to use the system hand cursor SetCursor(LoadCursor(IntPtr.Zero, IDC_HAND)); // Indicate that the message has been handled m.Result = IntPtr.Zero; return; } base.WndProc(ref m); } } The ImprovedCursorRendering.png shows the improved cursor.
Workaround: this.radChat1.ChatElement.InputTextBox.TextBoxItem.TextBoxControl.Multiline = true; this.radChat1.ChatElement.InputTextBox.ButtonsStack.Children.Remove(this.radChat1.ChatElement.ShowToolbarButtonElement); this.radChat1.ChatElement.InputTextBox.ButtonsStack.Children.Remove(this.radChat1.ChatElement.SendButtonElement); StackLayoutElement stack = new StackLayoutElement(); stack.MinSize = new Size(0, 60); this.radChat1.ChatElement.InputTextBox.Parent.Children.Add(stack); this.radChat1.ChatElement.InputTextBox.Parent.Children.Remove(this.radChat1.ChatElement.InputTextBox); stack.StretchHorizontally = true; stack.Orientation = Orientation.Horizontal; stack.Children.Add(this.radChat1.ChatElement.InputTextBox); stack.Children.Add(this.radChat1.ChatElement.ShowToolbarButtonElement); stack.Children.Add(this.radChat1.ChatElement.SendButtonElement); this.radChat1.ChatElement.ShowToolbarButtonElement.StretchHorizontally = false; this.radChat1.ChatElement.SendButtonElement.StretchHorizontally = false;
Workaround: manually increase the font of the controls protected override void OnShown(EventArgs e) { base.OnShown(e); var dpi = NativeMethods.GetSystemDpi(); this.Font = new Font(this.Font.Name, this.Font.Size * dpi.X / 96, this.Font.Style); this.radMenu1.Font = new Font(this.radMenu1.Font.Name, this.radMenu1.Font.Size * dpi.X / 96, this.radMenu1.Font.Style); this.radCommandBar1.Font = new Font(this.radCommandBar1.Font.Name, this.radCommandBar1.Font.Size * dpi.X / 96, this.radCommandBar1.Font.Style); }
How to reproduce: check the attached video Workaround: select a color from a different tab or use the color picker
FIX. RadPageView the isContentVisible property should work in all modes. RESOLUTION: This property should work only in ExplorerBar mode by design.
As workaround please, rename the controls with Find & Replace from VS Editor.
FIX. RadPageView - newly added page should be automatically selected in the properties window in design time Comment: When the above is implemented and a new page is added the following happens: 1. The RadPageView smart tag menu is closed 2. The new page is selected (the new page is a different component) 3. The smart tag menu of the new page is opened. This actually breaks the user experince instead of making it better.
To reproduce:
-Open the FileExplorer example.
- Resize the panel (see attached).
The performance of the DayView when the control is bound to a large number of recurring appointments and it is grouped by resources needs to be improved.
Use attached to reproduce.
Workaround:
public RadForm1()ChildRowHeight can be set on the main table element of the control like this:
this.radGridView1.TableElement.ChildRowHeight = 750;
When the grid is in a hierarchy and a parent row is expanded, the inner child template will create a new table element and its ChildRowHeight is 205 which is the default value. It would be expected that the height of the inner table element is initially set as the height of the main table element of the control.
A possible workaround is to handle the ChildViewExpanded event of the grid this way:
private void RadGridView1_ChildViewExpanded(object sender, Telerik.WinControls.UI.ChildViewExpandedEventArgs e)
