Data From Database display to textbox c#

Question

Good day Guys. I want to display the value of Townhouse into txthouse after selecting code from the data Thank you guys .

DataTable dtRefItem = Common.Common.GetData("SELECT Townhouse FROM County where code= '"+txtbox.text"'"

Answer 1

I would recommend using sql parameters instead of building up the sql command with just strings. this will help limit your exposure to sql injection and is just a good practice to start.

Answer 2

A DataTable normally contains multiple DataRow s. Even if you select only one you need to access that row from it's DataTable.Rows -property .

string townHouse = null;
if(dtRefItem.Rows.Count > 0)
{
    townhouse = dtRefItem.Rows[0].Field<string>("Townhouse");
}
txthouse.Text = townHouse;
