推荐答案

请更正您的sql连接字符串，您的datagrid将正常工作，否则，请对datagrid使用数据源连接向导.

Please rectify your sql connection string, your datagrid will work, or if else use data source connection wizard for datagrid.

连接字符串出了什么问题?实际上我是这里的新手.有人可以拿走我的文件并帮助我吗?

what is wrong with the connection string? actually I am a newbie here. is it possible if someone can take my files and help me out?

添加以下代码行
dataGridView1.DataBind();
在此行之后dataGridView1.DataSource = tbl;

所以最后两行将成为

dataGridView1.DataSource = tbl;
dataGridView1.DataBind();

Add the following lines of code
dataGridView1.DataBind();
After this line dataGridView1.DataSource = tbl;

So the last 2 lines will become

dataGridView1.DataSource = tbl;
dataGridView1.DataBind();
