[英]Control is not getting focused on Keyup event
Hi all I have created a dynamic combo box with a Textbox and a button to appear as dropdown style, every thing works fine but I handled keyup
event for the textbox so that when user enter some text I will search for the results and display them 大家好,我创建了一个带有文本框和一个按钮的下拉菜单的动态组合框,一切正常,但是我处理了文本框的keyup
事件,因此当用户输入一些文本时,我将搜索结果并显示它们
private void textBox1_KeyUp(object sender, KeyEventArgs e)
{
//Some code to filter my data
textBox1.Focus();
}
But I am unable to set the focus Immediately back to the textbox after results getting displayed so can some one help me 但是我无法在显示结果后立即将焦点设置回文本框,所以有人可以帮助我
Code I used is from here 我使用的代码是从这里

I have found that the Focus()
method is a bit flaky. 我发现Focus()
方法有点不稳定。
Other options: 其他选项:
textBox1.Select(textBox1.Text.Length - button1, 1);
...or simply: ...或简单地说:
textBox1.Select();
If you can verify that something else is going wrong, then this might be off base, otherwise you might simply be fighting weirdness. 如果您可以验证是否有其他问题出在哪里,那么这可能是错误的,否则您可能只是在与怪异作斗争。
