Dropdown has long delay

If I click on the dropdown arrow the box has a long delay before it opens (1 to 2 seconds). Before it opens the following runs in the Output Window. It does not matter if it is on my main form or a child form or with one item or 100. Once it runs ALL dropdowns work fine after that.

Thanks

Scroll jitter

I have a panel with AutoScroll = true.
Inside of this panel i have another panel with a grid docked to fill inside of it. lets say the height is 500px.
(Note: the panel is resized in the codebehind as needed depending on the row count, so its a growable panel but I don' think that will matter for replication).

When the main panel has a height of greater than 500px, you can tab between the cell just fine (even if the scroll bar is showing because you have other stuff in the main panel).

If you change the size of your panel to be less than 500 , so all the rows in the grid cant be displayed at once, there is a weird scrolling issue. When tabbing along the bottom rows the scrollbar moves up and then back down immediately causing the grid to "shake" / "jitter" / "bounce".

Any input on how to fix this issue would be great! thanks ahead of time.

Theme not responding to custom property changed

I'm extending a rad element for custom behavior (specifically, I'm making a multi-select drop down where the textbox acts as a search input). I'm trying to add a custom property, IsHighlighted to RadListBoxItem. I have a custom XML style sheet for my control which is being loaded and works, except that it doesn't highlight as expected.

Here are the modifications I've made:

I've created a MultiSelectComboBoxElement that extends RadComboBoxElement. I define a public static RadProperty IsHighlightedProperty in this class. It's static constructor registers my theme (XML) from storage (this was based on the default combobox theme) and registers the property as follows:

    
            IsHighlightedProperty = RadProperty.Register("IsHighlighted", typeof(bool), typeof(RadListBoxItem), new RadElementPropertyMetadata(false, ElementPropertyOptions.AffectsDisplay));

Notice, I'm trying to add the rad property to RadListBoxItem in the MultiSelectComboBoxElement static constructor.

My theme (XML) defines some visual settings for RadListBoxItems with selector condtions that use my new property. Here's one example:

    
            <XmlPropertySettingGroup> 
        
              <PropertySettings> 
        
                <XmlPropertySetting Property="Telerik.WinControls.Primitives.FillPrimitive.GradientStyle" Value="Linear" /> 
        
                <XmlPropertySetting Property="Telerik.WinControls.Primitives.FillPrimitive.NumberOfColors" Value="4" /> 
        
                <XmlPropertySetting Property="Telerik.WinControls.Primitives.FillPrimitive.GradientAngle" Value="90" /> 
        
                <XmlPropertySetting Property="Telerik.WinControls.Primitives.FillPrimitive.GradientPercentage" Value="0.5015975" /> 
        
                <XmlPropertySetting Property="Telerik.WinControls.Primitives.FillPrimitive.GradientPercentage2" Value="0.5623003" /> 
        
                <XmlPropertySetting Property="Telerik.WinControls.RadElement.Visibility" Value="Visible" /> 
        
                <XmlAnimatedPropertySetting EndValue="White" Property="Telerik.WinControls.VisualElement.BackColor" Value="" />
        
                <XmlAnimatedPropertySetting EndValue="255, 235, 173" Property="Telerik.WinControls.Primitives.FillPrimitive.BackColor2" Value="" />
        
                <XmlAnimatedPropertySetting EndValue="255, 215, 106" Property="Telerik.WinControls.Primitives.FillPrimitive.BackColor3" Value="" /> 
        
                          <XmlAnimatedPropertySetting EndValue="255, 213, 156" Property="Telerik.WinControls.Primitives.FillPrimitive.BackColor4" Value="" /> 
        
              </PropertySettings> 
        
              <Selectors> 
        
                <XmlClassSelector ElementClass="ListBoxItemSelectionFill" AutoUnapply="False"> 
        
                  <Condition xsi:type="XmlSimpleCondition" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
        
                    <Setting Property="Telerik.WinControls.UI.RadListBoxItem.IsHighlighted" Value="True" /> 
        
                  </Condition> 
        
                </XmlClassSelector> 
        
              </Selectors> 
        
             </XmlPropertySettingGroup>

I set the IsHighlighted value in code using item.SetValue(IsHighlightedProperty, true). This seems to work because subsequent calls to item.GetValue(IsHighlightedProperty) return true. I know telerik is using my theme as I see other visual changes and it does not throw any exceptions about not being able to find the IsHighlighted property, but the control style never changes at runtime (the item's background doesn't change). Any help would be greatly appreciated.

RadTextBoxElement databinding

Can a RadTextBoxElement be data bound?

The following code successfully binds a RadTextBox to a data field:

                            class MyObject         
                    {         
                        public double Number { get; set; }         
                        public string Title { get; set; }         
                    }         
                     
                    public Form1()         
                    {         
                        MyObject myObject = new MyObject() { Number = 5, Title = "Hello" };         
                        RadTextBox textBox = new RadTextBox();         
                        textBox.DataBindings.Add(new Binding("Text", myObject, "Title"));         
                        Controls.Add(textBox);         
                    }         

However, the following code fails to bind a RadTextBoxElement to the same data field:

                            class MyObject         
                    {         
                        public double Number { get; set; }         
                        public string Title { get; set; }         
                    }         
                     
                    public Form1()         
                    {         
                        MyObject myObject = new MyObject() { Number = 5, Title = "Hello" };         
                        RadTextBoxElement textBox = new RadTextBoxElement() { MinSize = new Size(200, 0) };         
                        textBox.DataBindings.Add(new Binding("Text", myObject, "Title"));         
                     
                        RadPanel elementsContainer = new RadPanel();         
                        elementsContainer.PanelElement.Children.Add(textBox);         
                        Controls.Add(elementsContainer);         
                    }         

Is databinding supported on a RadTextBoxElement? If so, am I doing it wrong?

Thanks,

Autosizing a RadTextBoxElement to its text

Hello -

I'm trying to cause a RadTextBoxElement to automatically size to its text, similar to the way a TextPrimitive automatically sizes to its text. Here is the code snippet:

                            public Form1()         
                    {         
                        StackLayoutPanel panel = new StackLayoutPanel();         
                        panel.Orientation = Orientation.Horizontal;         
                        panel.AutoSize = true;         
                        panel.Children.Add(new TextPrimitive() { Text = "Color:" });         
                        panel.Children.Add(new RadTextBoxElement() { Text = "Purple" });         
                        RadPanel elementsContainer = new RadPanel();         
                        elementsContainer.ThemeName = "Desert";         
                        elementsContainer.PanelElement.Children.Add(panel);         
                        Controls.Add(elementsContainer);         
                    }         
                     
                     

The TextPrimitive properly sizes to its text ("Color:"), but the RadTextBoxElement fails to size to its text ("Purple"). If I set AutoSize = true on the RadTextBoxElement, nothing changes. If I also set the AutoSizeMode to WrapAroundChildren, still no change. Can you advise me on how to make this work?

Thanks,

DockPanels don't resize properly after hide

I have a simple form with three docked windows. The first is on the bottom, taking half the screen, then two equal size panels on the top. When I hide the left top panel, then the right top panel, then unhide them (in either order), the left top panel is only about 25 pixels wide (probably your default minsize), and the right panel takes up the rest of the top half of the screen. Shouldn't unhide restore the panel to it's original size? I don't want to set the minsize to half the screen because my users might want to make it smaller. I have tried responding to the resize event, but then the contents of the DockPanels get unsysnced with the DockPanel size, although they are set up to fill the DockPanels. I've tried setting PreferredDockSize in the form load, that does not seem to help.
