based upon the below query you can search the data in table and display it to the grid view

C#

DataTable objdt = new DataTable();

var searchval=Textbox1.Text

C#

string query =@ "select * from TableName where name like '%" + searchval+ "%' or id like'%" + searchval+ "%'

C#

SqlDataAdapter da = new SqlDataAdapter(query, con);

C#

con.Open();
 da.Fill(objdt);
 con.Close();
 if (objdt.Rows.Count > 0)
 {
 GridView1.DataSource = objdt;
 GridView1.DataBind();
 }

Hello ,

You can use LINQ to extract any row from the datatable

C#

DataRow[] result = table.Select("Size >= 230);

"Size" in above line refer to Column name.

just need to define the condition in table.select("Condition")
Once you get the row array you can apply loop over it.

C#

foreach (DataRow row in result)
	{
	    Console.WriteLine("{0}, {1}", row[0], row[1]);
	}

Thanks.
Hope this helps.
