数据显示到列表框中 [英] data show into listbox

问题描述

我有一个文本框，如果我输入字符A，则它应该在列表框中显示与字符A相关的数据列表.

i Have one textbox if i enter character A then it should show list of data related to character A into Listbox.

推荐答案

山姆，您可以使用以下命令代码:

Hi Sam, You can use following code:

int index = listBox1.FindString(this.textBox1.Text);
if(0 < index)
{
  listBox1.SelectedIndex = index;
  listBox1.TopIndex = listBox1.SelectedIndices[0];
}

关于textBox1_Click事件:

On textBox1_Click event:

textBox1.Select(textBox1.Text.IndexOf(textBox1.text), textBox1.Text.Length);
textBox1.Focus();

希望对您有所帮助.

Hope it will help you.

使用DataBindingDource.Filter:

use DataBindingDource.Filter:

public void textBox1_TextChanged(object sender, EventArgs e)
{
    string filter = string.Format("Column_Name Like '%{0}%'", textBox1.Text.Replcae("'", "''").Replace("[", "[[]");

    // Column_Name iscolumn name of a table that you have bounded to the listBox
    BindingSource.Filter = filter;
}
