First of all your database design doesn't follow normalization rules.
Make it normalized.

Solution 1

Please try following.

public void bindddl()
 {
   string serial = TextBox8.Text;
   string[] s = serial.Split(',');
 
     for (int i = 0; i < s.Length; i++)
     {
         string s1 = s[i].ToString();
      
         string qry = "SELECT DISTINCT Vendor_Name FROM [VandorDetail] WHERE Asset_Type like'%'+s1+'%';
         SqlDataAdapter adpt = new SqlDataAdapter(qry, con);
         DataTable dt = new DataTable();
         adpt.Fill(dt);
         DropDownList4.DataSource = dt;
         DropDownList4.DataBind();
         DropDownList4.DataTextField = "Vendor_Name";
         DropDownList4.DataValueField = "Vendor_Name";
         con.Close();
     }
 
 }

It is showing error invalid column name S1

Try this.

string qry = "SELECT DISTINCT Vendor_Name FROM [VandorDetail] WHERE Asset_Type like '%"+s1+"%'";

Member 10578683 4-Jul-14 7:17am

Actually i need that vendor name that contains the assets present in my textbox.

Prasad Avunoori 4-Jul-14 7:45am

Then solution1 should work for you.

Why did you allow your table's columns to allow multiple values in one cell?

Member 10578683 4-Jul-14 8:54am
