Is there a place on web where we can get a list of countries and cities handy, and then populate into our dropdownlists in ASP.net page.
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?

I am referring to following line from this link [URL] ....
data 'continentId ' 'ddlContinents.ClientID'.val ''
In your code. i tried using this code and facing a tiny problem. In above mentioned code 'ddlContinents.ClientID'.val stores integer value in contentId for obvious reasons but the requirement of my code is different. i want to pass text which is selected instead of id no.for example if mumbai is listed as second option and i select mumbai it should store mumbai in contentId instead of 2 i.e. integer value.
Here is my scenario.In default.aspx page user selects the country, state, city from drop down list, and store them in cache for further use. but when other user open the web site from other computer it shows the same country, state, and city selected by user 1. Is there any problem related to cache? I have stored data as following.
cache["ctryID"] = ctryID;
cache["stateID"]= stateID;
cache["cityID"]= cityID;
I want to show default country, state , city at page load of default.aspx
I 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 am trying to select some data with dropdown lists which are related.

I think this needs to be a sticky since this is not solved anywhere that I have been looking... I have been googling this for a while now and came across the answer by shear luck and a simple typo when I was writing the code...
Problem: I have 2 dropdown lists...
ddllist1 and ddlist2... Both are code-behind populated via a sql DB.
they are cascading lists via the ajax control.
I am trying to dynamically populate them with values from a DB for edit reasons.
When I try to get them populated I kept getting the error...
"dropdownlist has a SelectedValue which is invalid because it does not exist in the list of items"
Solution:
1) get the values from the DB or from where ever...
2) create a sql select to get the values from the ddl db
3) set the ID of the first DDL control to cddcontrol1.SelectedValue = id (this is a number)
4) set the value of the DDL to the string value ddlist2.SelectedValue = value (this is a string)
here is the code.

I would like to populate Cascading DropDownList From SQL Server.
I prepare my project the same way as in this article: [URL] ....
But all the time I have "Method error 500" I read many articles how to solve this issue but without success.

1.tblUAP (UAP (PK), Start_Date,End_Date)
2.tblGAP(idGAP (PK),GAP,UAP(FK to tblUAP))

View 1 RepliesI'm wanting to maintain the dropdownlist values that were selected when i use postbackurl with a button. They cascading dropdowns are on a masterpage in an accordion pane. I select the 3 vales in the ddl and then presss a button which redirects to the new content page.
I've been able to get the values using previousPage.master.fincontrol... but am then setting the selectedValue in the page_init of the conent page, but they aren't set when the page loads... does anyone know where to put the code to set the values?
I really have no idea on this problem on the cascading dropdownlist. I have a cascading dropdownlist that bind with calling the web services.
I wan to do a autopostback to get the value of the Album GUId so that i can query out all the photo list of that album. it is working well if my page without the AlbumGUId query string.
my problem is:
when i redirect from other page and passing the Album GUId querystring to this page, it will display all my photo for this album guid. but when i change the album to Select which should be able to display all the Photos, it cannot display out. It only will work is when i choose another album and then go back to Select then it only can work..
