View 9 RepliesI am trying to get two cascading dropdownlist to work but cannot get either to populate. How do I de-bug this? I'm not getting any errors, just blank dropdowns.
I've been trying to fill in webservice from SQL Server. But in-case this was the problem. I found an example on this site to fill with test values, but this still does not work. Since I cannot even get first to populate, to simplify I'm just giving code for first dropdown and its function(s)

I have a cascading dropdownlist. The first drop down is for Departments and is databound on PageLoad from the database. The user then selects a department and the second dropdown is populated with the appropriate sub departments via JQuery/JSON which calls an httphandler. The problem is as follows: I select a department and the subdepartments are filled.
I finish what I'm doing on that screen and everything is fine. But then if I go to a different screen and add an additional subdepartment then come back to original screen, the new sub department won't appear in the cascading dropdown. I have to close the browser and restart the session in order for any new sub departments to appear even though they are in the database. I put a breakpoint in the httphandler and noticed that it is only called once per session per each department in the first dropdown. I don't know why this is happening. I want it to call the httphander EVERY time the index of the department dropdown is changed.

I'm building a WebControl for user registration. To expedite its use checks I used clientside validation through AjaxControlToolkit.ValidatorCalloutExtender. The validation is triggered when REGISTER button is pressed and popup information for missing or incorrect fields is showed. But I have a problem about a cascading dropdownlist(DDL) [Country]>>[City], because during the client-side validation I'm no more able to refresh my City DDL depending on the new selected Country. Server side, SelectedIndexChanged event is triggered but the DDL in the browser is not refreshed! (The DDL Country and City are Causevalidation=false) This occurs for each control on the page changed by server during client-side validation. How can I fix?

BindDropDownList(DDLtrade, "tradename", "Name", "id");
protected void BindDropDownList(DropDownList DDL, string spname, string dataTextfield, string dataValuefield) {
SqlCommand _cmd = new SqlCommand(spname, _cn);
_cmd.CommandType = CommandType.StoredProcedure;

SqlDataReader _dr = _cmd.ExecuteReader();
[Code] ....
NOW my problem is that when I select Item from ddlTrade it didn't show any thing in ddlTradeClass but when I delete this code
DDL.DataValueField=dataValuefield;
from BindDropDownList Metod and change like below:
protected void BindDropDownList(DropDownList DDL, string spname, string dataTextfield)
{
SqlCommand _cmd = new SqlCommand(spname, _cn);
_cmd.CommandType = CommandType.StoredProcedure;
_cn.Open();
