如何在添加新项目后自动滚动列表框,但前提是在添加项目之前滚动条位于底部?
你可以尝试一下:
listBox1.SelectedIndex = listBox1.Items.Count - 1; listBox1.SelectedIndex = -1;
此示例代码可以帮助您.我已经使用TextBox多次完成了这项工作,但是需要一段时间才能找到一个ListBox
显然,它只是一个带有Button和ListBox的Form.修改以满足您的需求:
private void button1_Click(object sender, EventArgs e) { listBox1.Items.Add("Some Text " + listBox1.Items.Count.ToString()); //The max number of items that the listbox can display at a time int NumberOfItems = listBox1.ClientSize.Height / listBox1.ItemHeight; if (listBox1.TopIndex == listBox1.Items.Count - NumberOfItems - 1) { //The item at the top when you can just see the bottom item listBox1.TopIndex = listBox1.Items.Count - NumberOfItems + 1; } }
