AJAX :: Autopostback On The Last List In A Cascading Dropdown List Series/ Invalid Postback Or Callback Argument

Aug 20, 2010

I have a Cascading drop down list that is working fine to load the correct lists however I would like to have the last one initiate a query and display a datagrid on the same page containing the results of the query. Without Ajax involved this seems rather easy by using autopostback on the drop downs. If I could do it through Ajax that would be great but I can settle with having the page to reload to display the data. Right now I'm not sure how to do either. I enabled autopostback on the last drop down and wrote a method for it but I get an error at runtime saying:

Invalid postback or callback argument

Forms Data Controls :: 2 Dropdown List / "Displaying A Dropdown List Of Categories With A --None -- Option?

Oct 10, 2010

I am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category". When i click on edit to edit or change category, it doesn't display the selected category.

How To Enable/Disable Button When A Dropdown List Selected Value Changes

Oct 28, 2010

I have a couple of dropdownlists and a button.when a user selects an item in the 1st dropdownlist,the 2nd dropdown is programmatically bound to a set of items(using an ajax request) depending on the value selected in the 1st dropdown.Then the user will have the ability to choose an item from the 2nd dropdown and click on the button,which performs some server side opeartions and returns the results.

But if the user tries to click on the button before the 2nd dropdown list is populated,user will receive an exception message.Instead of that I would like to prevent the user from clicking the button before the ajax request is completed to populate the 2nd dropdown.I tried using Button1.Enabled=false in the selectedvaluechanged event of 1st dropdown,which does n't seem to work.

Can Make A Dropdown List Act As A Command Button In A Lintview Control

Mar 19, 2011

I have a listview control that collects address among other things. I have a dropdown list for the country that defaults to "United States". For the state/region, I have another dropdown list populated with the states, and a textbox. I want either the state drop down list or the text box to be visible and enables at a time. The default is to have the dropdown list displayed. If the user changes the country, the state dropdown list should only be displayed if the user selects "United States" again. If any other country is selected, the text box should be displayed instead

AJAX :: Cascade Dropdowns With Web Methods?

May 10, 2010

I am showing state,city, zipcode in cascaded format. I designed cascade dropdown with asp dropdown list controls. I am loaing the citys & zipcode based on selection index changed.. here when I am selecting city the request is sending to server & its loading citys....

I don't want see post back operation on my page when I am selecting city & zipcode. So I am thinking to use Ajax cascade dropdown list to avoid sending the request for each selection.

If I use Ajax Cascade dropdownlist can i cascade the loading of citys & zipcode without using webservices?

If I use only webmethods for cascade dropdown it will work ?

AJAX :: Ajax Cascading Dropdown Control Not Working On IIS After Deploying?

Jan 12, 2011

I 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:

<form id="form1" runat="server"> <div> <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"> </asp:ToolkitScriptManager> <br /> <table> <tr> <td> <asp:DropDownList ID="DropDownList1" runat="server"

<br /> </td> </tr> <tr> <td> <asp:DropDownList ID="DropDownList2" runat="server" Height="20px" Width="257px"> </asp:DropDownList> <asp:CascadingDropDown ID="CascadingDropDown2" runat="server" Category="Type" TargetControlID="DropDownList2" PromptText="Select

I'm working with CascadingDropDown Lists, like CAR > MODEL > ACESSORIES.

Everything have worked fine, but there are some CAR MODELS that don't have ACESSORIES, so I want to HIDE the DROPDOWN "ACESSORIES" if a MODEL that doesn't have ACESSORIES be selected. If the user select a MODEL that has ACESSORIES, so the DROPDOWN ACESSORIES appears.

I think that I might use something like "DIV STYLE:HIDDEN"...

AJAX :: Repopulate Cascading Dropdown List Using Javascript

Mar 31, 2010

I've 2 dropdownlists, both are binded to a cascadingdropdown. Whenever I select an option in the 1st dropdownlist (parent), the options in the 2nd dropdownlist (child) will repopulate based on the options I selected in the parent dropdownlist. I need a javascript function to reset the options of both dropdownlists in their initial state (the prompt text).

I've tried changing the selectedIndex of the parent dropdownlist. However, this only changes the selected option in the parent dropdownlist. It does not reset the child dropdownlist to its initial state (which is supposed to be disabled and without any options). Need the script to reset the chained dropdownlists?
