You can use the FocusManager.FocusedElement attached property for this purpose. Here’s a piece of code that set the focus to TxtB by default. <StackPanel Orientation=”Vertical” FocusManager.FocusedElement=”{Binding ElementName=TxtB}”> <TextBox x:Name=”TxtA” Text=”A” /> <TextBox x:Name=”TxtB” Text=”B” /> </StackPanel> You can also use TxtB.Focus() in your code-behind if you don’t want to do this in XAML.
While @James’s answer above is correct. I’ve added more details to make it a completely working solution along with the use of focus event too. <html> <body> <input type=”text” id=”Text1″ name =”Text1″ value=””/> <input type=”text” id=”Text2″ name =”Text2″ value=””/> <SELECT><OPTION>ASDASD</OPTION><OPTION>A232</OPTION></SELECT> <INPUT TYPE=”CHECKBOX” id=”Check1″/> <INPUT type=”TEXT” id=”text3″/> <input type=”radio”/> <div id=”console”> </div> <textarea id=”textarea1″> </textarea> <script> … Read more
document.activeElement, it’s been supported in IE for a long time and the latest versions of FF and chrome support it also. If nothing has focus, it returns the document.body object.
I found this on silverlight.net, and was able to get it to work for me by adding a call to System.Windows.Browser.HtmlPage.Plugin.Focus() prior to calling RegularTextBox.Focus(): private void UserControl_Loaded(object sender, RoutedEventArgs e) { System.Windows.Browser.HtmlPage.Plugin.Focus(); RegularTextBox.Focus(); }
Unfortunately, it is almost a decade old well known FF bug (and now in Chrome too), which is not present in IE. All the Ctrl+T, Ctrl+Tab, Ctrl+W etc. keys just stop working when the focus is on a flash object. The worse thing is, no one seems to know the fix for it yet (see … Read more
What you describe works exactly as expected, assuming that you’ve set the HideSelection property of the ListView control to False. Here’s a screenshot for demonstration purposes. I created a blank project, added a ListView control and a TextBox control to a form, added some sample items to the ListView, set its view to “Details” (although … Read more
The Panel class was designed as container, it avoids taking the focus so a child control will always get it. You’ll need some surgery to fix that. I threw in the code to get cursor key strokes in the KeyDown event as well: using System; using System.Drawing; using System.Windows.Forms; class SelectablePanel : Panel { public … Read more
Handle the mousedown-event instead of the click-event. The mousedown event will be handled before the focus of another element is lost. In your mousedown eventhandler, you need to to prevent event default behavior. e.preventDefault(); // in your mousedown eventhandler JS-Fiddle demo
Rather than adding new control to window, I think you should give your Grid a name and react to the MouseDown event on your window, moving the focus to the Grid itself. Something like this: <Window x:Class=”WpfApplication1.Window1″ xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation” xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml” Title=”Window1″ Height=”412″ Width=”569″ MouseDown=”Window_MouseDown” Name=”window1″> <Grid ShowGridLines=”False” Background=”#01FFFFFF” KeyDown=”Grid_KeyDown” Name=”grid1″ Focusable=”True”> <TextBox Width=”120″ Margin=”117,61,0,0″ Name=”textBox1″ VerticalAlignment=”Top” … Read more
