DataGridView数据绑定和手动列

Question

I have a DataGridView on a form in c#, of the 7 columns i need on this DGV 6 of them will be pulled from an SQL DB and 1 of them i need to manually enter and its a link column . One thing i have going for me (i think) is that the manual column have the same data in every row.

I have been filling this DGV using a datatable, but i am not figuring out how to add manual columns and data bound ones in the same DGV. My column layout would look like this:

Column1 - DB Populated

Column2 - DB Populated

Column3 - DB Populated

Column4 - DB Populated

Column5 - DB Populated

Column6 - DB Populated

Column7 - Manually Populated

Can someone please explain to me how i would do something like this. if you can include the datatable definitions also it would be a big help, in order for me to verify that i am at least doing that the right way.

Answer 1

Do not know why this should be so difficult - do not keep any columns initially in the Datagrid. Bind it to a datasource and then add your columns manually

private void button1_Click(object sender, EventArgs e)
{
    con.Open();
    SqlCommand com = new SqlCommand("select * from yourtable", con);
    SqlDataAdapter adp = new SqlDataAdapter(com);
    DataSet ds = new DataSet();
    adp.Fill(ds);
    dataGridView1.DataSource = ds.Tables[0];
    dataGridView1.Columns.Add("manualcolumn", "manualcolumn");
}

Alternatively:

private void button1_Click(object sender, EventArgs e)
{
    con.Open();
    SqlCommand com = new SqlCommand("select * from yourtable", con);
    SqlDataAdapter adp = new SqlDataAdapter(com);
    DataTable dt = new DataTable();
    adp.Fill(dt);
    dataGridView1.DataSource = dt;
    dataGridView1.Columns.Add("manualcolumn", "manualcolumn");
}

con is SqlConnection

I hope this will give you a hint on adding dynamic columns to Grid-view.
