How to make autocomplete in wpf textbox?
提问by Ramji21
Here is the code I am using for search, it returns a value when we type a whole name, but I need a autocomplete textbox, that shows suggestions as I type a partial name.
这是我用于搜索的代码，它在我们键入全名时返回一个值，但我需要一个自动完成文本框，在我键入部分名称时显示建议。
private void textBox3_KeyUp_1(object sender, System.Windows.Input.KeyEventArgs e)//Name Search
{
SqlConnection con = new SqlConnection(constr);
con.Open();
SqlCommand cmd = con.CreateCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "Select [Patient ID],[Patient Name],[Gender],[StudyDateTim],[Modality],[Study Name] From RepView Where [Patient Name] like '%" + textBox3.Text + "%'";
cmd.ExecuteNonQuery();
DataTable dt = new DataTable();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
dataGrid1.ItemsSource = dt.DefaultView;
con.Close();
}

But if you don't want to create it yourself so you can just use an already created control by someone else. Download it from here.

you can also add the AutoCompleteBoxinto the toolbox by clicking on it and then Choose Items, go to WPF Components, type in the filter AutoCompleteBox, which is on the System.Windows
您还可以AutoCompleteBox通过单击将其添加到工具箱中，然后选择项目，转到 WPF 组件，输入过滤器AutoCompleteBox，它位于System.Windows
