问题描述
我希望在单个数据gridview中显示2个表来自第一个表的所有表和来自第二个表的1个列。
i尝试但是只显示空白单元格，而不显示存储数据
帮助我，我该怎么办？
我尝试过：
i want display 2 tables in single data gridview all tables from 1st table and 1 column from 2nd table.
i tried but there show only blank cells, not show stored data
help me, what should i do?
What I have tried:
public void disp_data()
{
DataTable dt = new DataTable();
{
SqlConnection con = new SqlConnection(strcon);
dataGridView1.DataSource = null;
dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
con.Open();
SqlCommand cmd = new SqlCommand("select id,cmpny_dtl.c_name as Name,cmpny_dtl.adrs as address,cmpny_dtl.state as state,s.State as state,cmpny_dtl.c_phone as phone,cmpny_dtl.wbsit as website" + " from cmpny_dtl join State s on s.State = s.State", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
con.Close();
dataGridView1.ColumnCount = 9;
dataGridView1.Columns[0].HeaderText = "id";
dataGridView1.Columns[0].DataPropertyName = "id";
dataGridView1.Columns[0].Visible = false;
dataGridView1.Columns[1].HeaderText = "Name";
dataGridView1.Columns[1].DataPropertyName = "c_name";
dataGridView1.Columns[2].HeaderText = "address";
dataGridView1.Columns[2].DataPropertyName = "adrs";
dataGridView1.Columns[3].HeaderText = "GST";
dataGridView1.Columns[3].DataPropertyName = "GST";
//dataGridView1.Columns[3].Visible = false;
dataGridView1.Columns[4].HeaderText = "state";
dataGridView1.Columns[4].DataPropertyName = "State";
//dataGridView1.Columns[4].Visible = false;
dataGridView1.Columns[5].HeaderText = "phone";
dataGridView1.Columns[5].DataPropertyName = "c_phone";
dataGridView1.Columns[6].HeaderText = "website";
dataGridView1.Columns[6].DataPropertyName = "wbsit";
dataGridView1.Columns[7].HeaderText = "servicetax";
dataGridView1.Columns[7].DataPropertyName = "servicetax";
dataGridView1.Columns[8].HeaderText = "adsnldtl";
dataGridView1.Columns[8].DataPropertyName = "adsnldtl";
dataGridView1.DataSource = dt;
}
}
