Question

I have a GirdView table in my application. I have a Delete link button and a checkbox in my first column. Below are snapshots:

I can manually delete each row by clicking Delete link button on each row.

However, I would want to enable the checkbox to delete multiple rows.

Below is my code for my Delete link button:

LinkButton lnk = (LinkButton)sender; 
        string stid = lnk.CommandArgument.ToString();
        SqlConnection conn = new SqlConnection("Data Source=DATASOURCE");
        string sql = string.Format("DELETE FROM [UserDB] where Employee like '%{0}%'",stid);
        SqlCommand cmd = new SqlCommand(sql,conn);
        conn.Open();
        cmd.ExecuteNonQuery();

Below is my code for the current Delete Checked button:

bool atLeastOneRowDeleted = false;
        foreach (GridViewRow row in GridView1.Rows)
        {
            // Access the CheckBox
            CheckBox cb = (CheckBox)row.FindControl("UserSelection");
            if (cb != null && cb.Checked)
            {
                atLeastOneRowDeleted = true;
                // How do I get the value from my Employee column?
                string userID = ???;


           SqlConnection conn = new SqlConnection("Data Source=DATASOURCE");
           string sql = string.Format("DELETE FROM [UserDB] where Employee like '%{0}%'",userID);
           SqlCommand cmd = new SqlCommand(sql,conn);
           conn.Open();
           cmd.ExecuteNonQuery();
            }
        }

I would like to know how should I grep userID, which is Employee key in the GridView, to INSERT it into my SQL delete statement?

I think you want

bool atLeastOneRowDeleted = false;
    foreach (GridViewRow row in GridView1.Rows)
    {
        // Access the CheckBox
        CheckBox cb = (CheckBox)row.FindControl("UserSelection");
        if (cb != null && cb.Checked)
        {
            atLeastOneRowDeleted = true;
            //assuming you have the ID column after the controls
            string CusId = (row.Cells[3].Text);


       SqlConnection conn = new SqlConnection("Data Source=DATASOURCE");
       string sql = string.Format("DELETE FROM [UserDB] where Employee like '%{0}%'",userID);
       SqlCommand cmd = new SqlCommand(sql,conn);
       conn.Open();
       cmd.ExecuteNonQuery();
        }
    }
