Solution 1

You could create a View on the SQL Server, test it, and use that as your DataSource.
Using a BindingSource is recommended, see this example: DataGridView.DataSource Property (System.Windows.Forms)[^]
Also there could be a problem with your join, take a look here for a join example:
SQL Joins[^]
I think the join should be like this:

SQL

from cmpny_dtl join State s on s.State = cmpny_dtl.State

this is not helpfull

RickZeeland 13-Jun-17 5:14am

Yes, it is, but you have to show some effort !
Did you try to create a view and tested that first ?

Deekshaa Singh Chauhan 13-Jun-17 6:02am

i want save state_id but show state name

RickZeeland 13-Jun-17 6:09am

To make things more clear maybe it would be a good idea to use SQL Server Management Studio, Right-click on your tables, and select "Create script". Add the generated scripts to you question by hovering over it with the mouse and select "Improve question".

this code worked bt show only 1 row and sometime that give error in data grideview id column

DataTable dt = new DataTable();
{
SqlConnection con = new SqlConnection(strcon);
dataGridView1.DataSource = null;
dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
con.Open();

SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
con.Close();
//dataGridView1.ColumnCount = 7;
//dataGridView1.Columns[0].HeaderText = "id";

}

if (dataGridView1.CurrentRow.Index != -1)
{
//if (dataGridView1.CurrentRow.Cells[10].Value != DBNull.Value)
//{

I would recommend to test your query first in SQL Server Management Studio and see if that returns more rows.

Deekshaa Singh Chauhan 13-Jun-17 6:46am

I tested that this only show one row but why? where is problem

RickZeeland 13-Jun-17 7:52am

As I do not have access to your database and have no information about it, I can not help you further. You can try modifying your query in SQL Server Management Studio and see what happens, good luck !
