尝试

{

SqlConnection connect = new SqlConnection（）;

connect.ConnectionString = ConfigurationManager .ConnectionStrings [ApplicationServices]。ConnectionString;

connect.Open（）;

SqlDataAdapter da = new SqlDataAdapter（SELECT *通过ID_CODE从LOANS订购，连接;



SqlCommand SqlCmd = new SqlCommand（sp_searchActLoan，connect）;

SqlCmd.CommandType = CommandType.StoredProcedure;



SqlCmd.Parameters.AddWithValue（@ searchString，txt_Search.Text）;

SqlCmd.ExecuteNonQuery（） ;



SqlDataAdapter daa = new SqlDataAdapter（）;

daa.SelectCommand = SqlCmd;



DataSet dsas = new DataSet（）;

daa.Fill（dsas，searchResults）;

GridView1.DataSource = dsas;

//GridView1.DataSourceID = null;

GridView1.DataSource = dsas;

GridView1.DataBind（）;

connect。关闭（）;

推荐答案

按照消息的说明进行操作！

您在标记中初始化DataSourceID，而不是从代码隐藏中初始化DataSource。 。

Do as the message tells you!
You initialize DataSourceID in the markup, than initialize DataSource from the code-behind...

DataSourceID="SqlDataSource1"

GridView1.DataSource = dsas;

GridView无法决定将哪个用于数据呈现。你必须选择!!!删除其中一个......

The GridView can't decide which to use for data rendering. You have to choose!!! Remove one of them...

这篇关于DataSource和DataSourceID都在'GridView1'上定义。删除一个定义。的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
