问题 I have an UltraWinGrid and I want to give the focus to a specific cell and make it enter edit mode programmatically ( no click ).

问题 I've set stuff in a DataGridTemplateColumn.CellEditing DataTemplate.

Consider this example, when you go edit mode, the textbox is not keyboard-focused: <Window x:Class="MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <DataGrid

问题 According to this answer I try to create a page where if the input field get focused than the height is scaled down small enough that the page will be not scrollable. If the input field lose the focus than everything is made back to the original state. I tried this technique without events only entering the code through the console and it worked like a charm, but after I bind these to events, everything is ruined. I realized that after I click into the input field and the binded function

问题 I want to implement autoselect when a user tabs through the JTextFields and JSpinners in my forms.

问题 I can't seem to set the focus on Bootbox's textfield automatically. here's my code: function setCode(myCode){ bootbox.confirm("Enter your PIN: <input id='pin_code' type='password' name='pin_code'></input>", function(result) { if(result) console.log($("#pin_code").val()); }); $("#pin_code").focus(); }; Perhaps something about bootbox's code is getting in the way? 回答1: You can register a shown event handler that sets the focus (as suggested by @Shiny). However, as of Bootstrap 3 and Bootbox v4
