AJAX :: Ajax Cascading Dropdown Control Not Working On IIS After Deploying?
Jan 12, 2011I am new to Ajax Control Toolkit, with the help of online tutorials I had created a cascading dropdown list in asp.net and tested it on my local machine. For this dropdown list data source would be an xml file (which is saved on my local machine c drive). I haven't encountered any issues until I deploy the precompiled web site on to IIS 7. When I open the web site from IIS I would see the two dropdown boxes on the web page with an error "Method error 500". I believe this error occured due to incorrect xml file
path provided on IIS. I had copied xml and xsd files into IIS server C drive but it did not help out and then I created a network map and placed the xml and xsd files in that shared folder tried to access that path from web service, it's working on local machine but not on IIS. It would be great, if any one could explain me the solution.
Following is the .aspx and .asmx code:
.aspx code:

AJAX :: Cascading Dropdown Selected Value Not Working?
Feb 9, 2011I have a web form where I have three dropdowns for Country State And City and there corresponding
ajaxToolkit:CascadingDropDowns.
The dropdowns are working perfectly fine with the web service methods. i.e country loading initially and then State as per selected Country and City as per the selected City.
The problem occurs when I try to set selected values in these dropdowns as per the Values previously saved.
The Country loads properly and the selected value is set according.
The State is filled as per the selected country but its selected value is not set.
The City is not loaded at all (as the state doesn't have a selected value)
The Code is as Follows:

AJAX :: Cascading Dropdown Inside Of A Listview?
Jan 26, 2010Does anybody have a working example of a cascading dropdown inside the insertitem and edititem templates of a listview? I have been working on this for a couple of days now with only marginal success, and I fear I will have to abandon work on this due to time constraints.
The areas where I'm having difficulty are:
I just have two dropdowns(dds). In the insertitem row, I am able to have the user choose from dd1 and set a value in dd2. This works fine, but the user must be able to go back and change dd1 and have the proper value set as a selected default item in dd2. I can't get this to work.
In the edititem rows, I'm having difficulty setting the selected value of the dropdowns when displaying the row to be edited, and am running into the same problem as above when the user changes a dd1 value - the dd2 value does not reset to the proper selected default item.
My strategy for the edit items has been to try to get elements from the dataset bound to the listview to flow to the web service routines as contextkeys. I then iterate through the data values to be displayed in the dd and if the value = contextkey value, then set its isDefaultValue to true when adding it to the list of CascadingDropdownNameValue items.
The solution needs to work in the real world. That means Master Pages, so any fancy javascript workarounds need to take this into account.

View 8 RepliesAJAX :: Cascading Dropdown And Triggering Events?
Oct 7, 2010I have a big form wrapped in an updatepanel (for other reasons). Inside this form is a section that needs to have it's own asynchronous postback -- there is a cascading dropdown and, based on the selections, you can add a product to a list. Once that list is populated, it can be submitted with the rest of the form.
So in this little section I have :
A Label for testing the button event (the label gets updated)5 Cascading Dropdowns (which are working fine)A button The button event changes the label text. If I click the button right away, it updates the label as expected. However, if I click the button *after* doing any selections on the Cascading Dropdowns, the label does not get updated. Things I have tried:
Removing the updatepanel surrounding the form -- yes, then the event gets fired, but I need it all in the updatepanel.Adding UpdateMode=Conditional -- no changeAdding an update panel just around this section -- no changeAdding Triggers either to the big updatepanel or to one just around this section -- no change
Thoughts?
