我正在使用下面的代码来绑定我的datagridview
和select
语句,以便获取我需要的记录。
在这些代码行中一切正常,但我想在用户输入textbox
内容时自动过滤记录,当删除数据时,记录返回初始状态,当表单是加载。谁能给我一些提示?
这是我的代码:
public nir()
{
InitializeComponent();
nir_load();
}
void nir_load()
{
string cs = "Data Source=IS020114\\CODRINMA;Initial Catalog=gcOnesti;Integrated Security=True";
string select = "select p.cod as Numar, p.data as Data, p.doc_cod as NrDocFurnizor, g.nume as Gestiune, c.nume as Furnizor, p.validat as Validat, p.facturat as Contat from primar p inner join gestiuni g on p.part2=g.gest_id inner join cf c on p.part1=c.cf_id where p.tip=2";
using (SqlConnection con = new SqlConnection(cs))
{
SqlCommand cmd = new SqlCommand(select, con);
con.Open();
SqlDataAdapter sda = new SqlDataAdapter();
sda.SelectCommand = cmd;
DataTable dt = new DataTable();
sda.Fill(dt);
BindingSource bs = new BindingSource();
bs.DataSource = dt;
dataGridView1.DataSource = bs;
}
}
private void btnSearch_Click(object sender, EventArgs e)
{
string cs = "Data Source=IS020114\\CODRINMA;Initial Catalog=gcOnesti;Integrated Security=True";
string select = "select p.cod as Numar, p.data as Data, p.doc_cod as NrDocFurnizor, g.nume as Gestiune, c.nume as Furnizor, p.validat as Validat, p.facturat as Contat from primar p inner join gestiuni g on p.part2=g.gest_id inner join cf c on p.part1=c.cf_id where cod='" +txtnr.Text+"' and data='" + dtpData.Value.ToString("yyyy-MM-dd") +"' and p.tip=2";
using (SqlConnection con = new SqlConnection(cs))
{
SqlCommand cmd = new SqlCommand(select, con);
con.Open();
SqlDataAdapter sda = new SqlDataAdapter();
sda.SelectCommand = cmd;
DataTable dt = new DataTable();
sda.Fill(dt);
BindingSource bs = new BindingSource();
bs.DataSource = dt;
dataGridView1.DataSource = bs;
}
}
答案 0 :(得分:0)
我使用了private void txtNumber_KeyUp(object sender, KeyEventArgs e)
事件并且工作正常。
