Hi Guys ,
I built windows application form and connected to the database through LINQ ADO.NET entity Data Model.
Now I added some Datagridview to my app and I'm trying to write code to show columns from multiple tables but really don't know how to do it.
Can someone give me example how to write this code.
Here is the SQL code with all the tables and columns I need to show in my C# application datagrid.

Please can I have some more deeply help I'm really new for this world and the example you provided me is not too clear for me.
I was trying something like that but nothing seem to be working get many red marks.:)

private void Form1_Load(object sender, EventArgs e)
{
var db = new rmsmasterdbtestEntities2();
dataGridView1.DataSource =
EnumerableRowCollection<DataRow> contactQuery = from row in DataSet.tables["
}
Read the comments given above the GetData() function. You are going to fetch the data from Database right? Replace GetData() with those statements.
Thank you very much but I couldn't get it that way and I figured it is going to be a lot of work as I have many tables and columns to add, so I connected to the storage procedure the SQL guy gave me, in this way I could get all the columns I need for the datagrid.
now it is working
private void Form1_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'rmsmasterdbtestDataSet.SALESANALYSIS' table. You can move, or remove it, as needed.
this.sALESANALYSISTableAdapter.Fill(this.rmsmasterdbtestDataSet.SALESANALYSIS);
}
now it is working
