Posted By:Naresh       Posted Date: March 01, 2010    Points: 10    Category: ASP.NET Controls    URL: http://www.dotnetspark.com  

If we want to bind the values for drop down list from database by getting a value from another drop down list box.

OleDbConnection con = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Datasource=c:/m/student.mdb");           
OleDbCommand cmd = new OleDbCommand("select RollNo from Student_Details where region='" + this.DropDownList2.Selectedvalue.Text + "'", con);
dr = cmd.ExecuteReader();
this.DropDownList2.DataSource = dr;
this.DropDownList2.DataTextField = "RollNo";
this.DropDownList2.DataValueField = "RollNo";
