C# 使用tableadapter windows窗体C制作自动完成文本框
我有这段代码来自动完成我的搜索文本框C# 使用tableadapter windows窗体C制作自动完成文本框,c#,winforms,autocomplete,tableadapter,C#,Winforms,Autocomplete,Tableadapter,我有这段代码来自动完成我的搜索文本框 AutoCompleteStringCollection coll = new AutoCompleteStringCollection(); DataTableReader reader=this.customerTableAdapter.GetData().CreateDataReader(); while(reader.Read()){ coll.Add(reader.GetString(0));
AutoCompleteStringCollection coll = new AutoCompleteStringCollection();
DataTableReader reader=this.customerTableAdapter.GetData().CreateDataReader();
while(reader.Read()){
coll.Add(reader.GetString(0));
}
search.AutoCompleteCustomSource = coll;
这是最好的表演方式吗?或者是否有一个函数可以使自动完成源直接指向列本身
此外,这段代码只过滤名字,但当我在gridview中使用这段代码时,它提供了更好的搜索能力,因此它可以捕获名字的任何部分
private void search_KeyUp(object sender, KeyEventArgs e)
{
string outputInfo = "";
string[] keyWords = search.Text.Split(' ');
foreach (string word in keyWords)
{
if (outputInfo.Length == 0)
{
outputInfo = "(Name LIKE '%" + word + "%')";
}
else
{
outputInfo += " AND (Name LIKE '%" + word + "%')";
}
}
//Applies the filter to the DataView
myView.RowFilter = outputInfo;
}
建议请这段代码不使用循环,它在字符串数组中填充表的一列,然后用作autoCompleteSource
根据我的说法,一切都是正确的。关键字搜索代码呢?如何将其合并到自动完成源中
DataTable dt = this.data_allDataSet.merchandise;
//use LINQ method syntax to pull the Title field from a DT into a string array...
string[] postSource = dt
.AsEnumerable()
.Select<System.Data.DataRow, String>(x => x.Field<String>("name"))
.ToArray();
var source = new AutoCompleteStringCollection();
source.AddRange(postSource);
cat_name.AutoCompleteCustomSource = source;
cat_name.AutoCompleteMode = AutoCompleteMode.Suggest;
cat_name.AutoCompleteSource = AutoCompleteSource.CustomSource;
