推荐答案

1.为comboBox创建TextChanged事件
2.在查询的where子句中将输入文本作为参数传递
3.使用带有该参数的like运算符获取结果并将其绑定到comboBox


例如:

1. Create TextChanged Event for comboBox
2. Pass input text as parameter in where clause of the query
3. use the like operator with that parameter to get the the result and bind this to comboBox


for example:

Select * from tbl_name
where column_name like ''%''+@Param+''%''
