using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Data;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
GridView1.Attributes.Add("bordercolor","red");
MergeGrid();
}
protected void MergeGrid()
{
SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["dbcon"].ToString());
con.Open();
SqlDataAdapter adp = new SqlDataAdapter("select * from
Reg", con);
DataSet ds1 = new DataSet();
adp.Fill(ds1);
adp = new SqlDataAdapter("select * from
sale", con);
DataSet ds2 = new DataSet();
adp.Fill(ds2);
ds1.Merge(ds2,true);
if (ds1.Tables[0].Rows.Count > 0 &&
ds2.Tables[0].Rows.Count>0)
{
GridView1.DataSource = ds1;
GridView1.DataBind();
}
con.Close();
}
}
Create Two Database tables
Next - Add New Webforms - Select GridView From
Toolbox
Next - Select Two Database table to Two DataSet & Merge & Bind Gridview
It's better to use union in sql query:
ReplyDeleteDataSet myDS = new DataSet();
new SqlDataAdapter("select username, sal from table1 union all select username, sal from table2", con).Fill(myDS);
