Hi all,

I try to focus textbox but when selecting tabControl1, focus radio. How do i focus into textbox

void tabControl1_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            if (!(e.Source is TabItem))
            {
                return;
            }
            if(tabControl1.SelectedItem.Equals(tabItem1))
            {
                this.tabItem1.Focus();
                UpdateLayout(); //tabControl1.UpdateLayout();
                this.textBox1.Focus();
            }
            else
            {
                this.tabItem2.Focus();
                this.tabItem2.UpdateLayout();
                this.txtFocusTab2.Focus();
            }
        }

推荐答案

这不是重点，这是选择。方法如下：

http://msdn.microsoft.com/en-us/library/system.windows.forms.tabcontrol.selectedindex(v = vs.110）.aspx [ ^ ] ，

http://msdn.microsoft.com/en-us/library/system.windows.forms.tabcontrol.selectedtab(v=vs.110).aspx [ ^ ]。br />


请注意，这两个属性都是读写的。设置者具有实际选择所需选项卡的副作用。

This is not focusing, this is "selection". Here is how:
http://msdn.microsoft.com/en-us/library/system.windows.forms.tabcontrol.selectedindex(v=vs.110).aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.forms.tabcontrol.selectedtab(v=vs.110).aspx[^].

Note that both properties are read-write. The setters have the side effect of actually selecting the tab you want.
