加载用户控件时,如何将焦点设置在文本框上?
在Winforms中,我在textbox1.focus()
中写了usercontrol.load()
,但是没有用。
最佳答案
请尝试.Select()方法。
textBox1.Select();
要么
private void Form1_Load(object sender, EventArgs e)
{
this.ActiveControl = textBox1;
}
另外,您可以尝试:
private TextBox TextFocusedFirstLoop()
{
// Look through all the controls on this form.
foreach (Control con in this.Controls)
{
// Every control has a Focused property.
if (con.Focused == true)
{
// Try to cast the control to a TextBox.
TextBox textBox = con as TextBox;
if (textBox != null)
{
return textBox; // We have a TextBox that has focus.
}
}
}
return null; // No suitable TextBox was found.
}
private void SolutionExampleLoop()
{
TextBox textBox = TextFocusedFirstLoop();
if (textBox != null)
{
// We have the focused TextBox.
// ... We can modify or check parts of it.
}
}
