Dropdownlist assign selected value

I have a dropdownlist which I populate from a db table and its value is in one column and the display text is in another.  When I run my report I do a join to get the text to display on the page based on the value column.  Here is my query:


SELECT fcomp_assign, 
	(SELECT fcode_cmmt
	 FROM fcode_mstr
	 WHERE fcode_value = fcomp_assign 
	 AND fcode_fldname = 'fcomp_assign') AS AssignedTo
FROM fcomp_mstr
WHERE fcomp_comp_id = 8

 This returns what I expect: 6 and Customer Service

Problem is I want to populate the list with this query:

SELECT fcode_cmmt, fcode_value
FROM fcode_mstr
WHERE fcode_fldname = 'fcomp_assign'

Which returns this:

Shipping 1
Purchasing 2
Inventory Control 3
Quality 4
Engineer Services 5
Customer Service 6
Production 7
Accounting 8

 And assign the selected value with the previous query from a different data source.  I am sure it is possible but I haven't been able to find out how.

Your question is not clear. Do you want to implement a cascading drop-down - on seelction of one item from first Dropdown, it will populate second dropdown?

4/7/2008 5:44:30 AM

No the cascading part is easy to me.  What I need to do is populate the ddl items with data from one table and the selected item value is a value stored in another table. 

To take it a bit more in detail:  

My complaint master table stores comp_assign = 3 for complaint_id #1.  This would equal Inventory Control 3 in my code master table.  I need to display the ddl text and store the ddl value which are in two seperate queries and tables.

Hi b471code3 ,

Do you want to set datatextfield and datavaluefield to two columns which in two different tables and there are FK relationship between these two tables ?

If so, my sample will be helpful.


        DataSet ds = new DataSet();
        DataTable catogory = new DataTable();
        catogory.TableName = "cc";
        DataRow dr1 = catogory.NewRow();
        dr1["id"] = 1;
        dr1["name"] = "cat1";
        DataRow dr2 = catogory.NewRow();
        dr2["id"] = 2;
        dr2["name"] = "cat2";

        DataTable item = new DataTable();
        item.TableName = "ii";
        DataRow dr3 = item.NewRow();
        dr3["parent"] = 1;
        dr3["name"] = "item1cat1";
        DataRelation rel = new DataRelation("test", ds.Tables["cc"].Columns["id"], ds.Tables["ii"].Columns["parent"]);

        for (int i = 0; i < ds.Tables["ii"].Rows.Count; i++)
            ListItem ditem = new ListItem();
            ditem.Text = ds.Tables["ii"].Rows[i]["name"].ToString();
            DataRow parent = ds.Tables["ii"].Rows[i].GetParentRow("test");
            ditem.Value = parent["name"].ToString();

So I have tried your example in my setting and have not yet been able to be successful.  Is there no other way to do this within the GUI interface?  Does it all have to be done programatically?

As per my understanding you have to populate the datatext and datavalue to the DDL and code is here

And if i am wrong plz let me know


   Dim cmd As OdbcCommand = New OdbcCommand("select * from states where country_id=" & country.SelectedValue & " order by state_name", con)
   Dim myreader As Odbc.OdbcDataReader
     myreader = cmd.ExecuteReader()
       Do While myreader.Read()
            Dropdownlist1.Items.Add(New ListItem(myreader("Datatext_column"), myreader("DataValue_Column")))
  If you have a problem with this plz let me know

This does look like what I am going for.  What I have is a Complaint table with many fields, one of them being the AssignedTo value (INTEGER) which is joined back to a Code table which holds all the items for the DDL.  So when I populate my DDL I run this query: SELECT * FROM CodeMstr WHERE CodeName = "CompAssign". 

This returns: (dataText, dataValue)

Shipping, 1
Customer Service, 2
Purchasing, 3

What I want is to have the selected value be "Shipping" when the complaint has the AssignedTo value of 1 in that field.  If I see what you are doing, I need to pass the AssignedTo value as a parameter to my SP in order to get the selected value to work right.  Is this correct?

I think Yes...  the way you wanted the above code does and see the query

SELECT * FROM CodeMstr WHERE CodeName = "CompAssign". 


For displaying in the DDL it takes shipping and value will be one ...........If you have any question on this plz feel free to ask

I also have a submit button on my page which when clicked is supposed to get the number I have selected in my dropdownlist. But this does not happen. It keeps returning 1 even if I select 4. I'm guessing whenever the page is loaded the dropdownlist is being created again and hence it selects the first number which is 1. Can anyone tell me how to solve this problem?
