It is possible to add one control, but when when you try to add other controls to the layout, just sits where you place it rather than split in to sections.
Expected:
Actual:
I can not add any type of control to the layoutControlGroupItem. I have a screen recording of me trying to follow the procedure shown but it is 60M so I can't attach it. I shared the file on my OneDrive if you would like to access it that way.
To reproduce:
private void RadButton5_Click(object sender, EventArgs e)Workaround:
private void RadButton5_Click(object sender, EventArgs e)
{
RadButton labelControl = new RadButton();
labelControl.Size = new Size(200, 30);
labelControl.Text = "Test";
((RadLayoutControlControlCollection)this.radLayoutControl1.Controls).RemoveInternal(layoutControlItem1.AssociatedControl);
((RadLayoutControlControlCollection)this.radLayoutControl1.Controls).AddInternal(labelControl);
layoutControlItem1.AssociatedControl = labelControl;
layoutControlItem1.UpdateControlBounds();
}
Workaround: handle the RadPropertyChanging and RadPropertyChanged public partial class RadForm1 : Telerik.WinControls.UI.RadForm { public RadForm1() { InitializeComponent(); this.layoutControlGroupItem1.RadPropertyChanging += LayoutControlGroupItem1_RadPropertyChanging; this.layoutControlGroupItem1.RadPropertyChanged += LayoutControlGroupItem1_RadPropertyChanged; } private void LayoutControlGroupItem1_RadPropertyChanged(object sender, RadPropertyChangedEventArgs e) { if (e.Property == LayoutControlGroupItem.IsExpandedProperty) { Console.WriteLine("IsExpanded Changed"); Console.WriteLine("Old Value: " + e.OldValue); Console.WriteLine("New Value: " + e.NewValue); } } }
Workaround: set a White back color to the control in the designer or use the attached custom theme
To reproduce: - Add layout control to a standard Form. - Make the form smaller so a scrollbar appears in the layout control. - There is an exception when you are scrolling. Workaround: Use RadForm instaed.
To reproduce: - Start the attached project. - Collapse and then expand the group. - The label should remain hidden. Workaround: bool labelVisiable = false; private void TxtIdNro_VisibleChanged(object sender, EventArgs e) { if (txtIdNro.Visible && !labelVisiable) { txtIdNro.Visible = false; } }
Please run the attached sample project and follow the steps in the document locate din the zipped folder. Workaround: this.radLayoutControl1.VerticalScrollbar.ValueChanged += VerticalScrollbar_ValueChanged; private void VerticalScrollbar_ValueChanged(object sender, EventArgs e) { this.Width += 1; this.Width -= 1; }
Workaround: access the tabbed group and remove the group item manually this.layoutControlTabbedGroup1.ItemGroups.Remove(this.layoutControlGroupItem1); this.radLayoutControl1.HiddenItems.Add(this.layoutControlGroupItem1);
The attached video shows how this can be reproduced. Workaround: private void RadLayoutControl1_MouseWheel(object sender, MouseEventArgs e) { HandledMouseEventArgs ee = (HandledMouseEventArgs)e; ee.Handled = true; }
To reproduce: - Open the attached project. - Select the second tab and then the inner tabs. - The layout is not updated. Workaround: private void TabStrip_ItemSelected(object sender, RadPageViewItemSelectedEventArgs e) { LayoutControlTabStripElement el = sender as LayoutControlTabStripElement; foreach (LayoutControlTabStripItem item in el.Items) { var groupItem = item.LayoutGroupItem; groupItem.Visibility = Telerik.WinControls.ElementVisibility.Visible; groupItem.InvalidateMeasure(true); groupItem.InvalidateArrange(true); groupItem.UpdateLayout(); groupItem.Visibility = Telerik.WinControls.ElementVisibility.Collapsed; } foreach (LayoutControlTabStripItem item in el.Items) { if (item == e.SelectedItem) { var groupItem = item.LayoutGroupItem; groupItem.Visibility = Telerik.WinControls.ElementVisibility.Visible; break; } } } // access event layoutControlTabbedGroup4.TabStrip.ItemSelected += TabStrip_ItemSelected;
To reproduce: - Create a new project and add a blank user control to it. - Add RadLayoutControl to the user control. - Add another control to the layout control. Workaround Use a form instead of user control. Then add the controls from the form at runtime.
To reproduce: - Add RadPageView with four pages to a form. - In the firs page add RadLayoutControl with some items in it. - Select the second page and try to add controls to it. Workaround: - Place the layout control in a separte user control and then add it to the main form.
