Web Forms :: Creating Two Cascading Dropdown Menus?
Apr 30, 2010
I need to create 2 cascading dropdown menus for a website. I am really new to ASP so don't understand a lot of it yet.. now is that the website pulls the list items from a SQL database and I don't want to use this method. I need to use either JavaScript or just hard code the items. Here are the directions for what I need to do:
Drop down list box for selecting a state (populate it with names of five states)
I have a masterpage that contains all my dropdown menu controls. The 2 largest browser hits on my site are IE and Firefox (in that order). I just recently updated to the latest version of Firefox and now... my dropdown menus no longer appear with Firefox but still do with IE.
There is nothing strange going on with my masterpage and it used to work fine in both IE and Firefox. Not too sure what is going on and can't seem to find anyone else who has posted on this subject.
I am designing my own Customize Calendar for my webproject.Using Calendar Control of asp.net2.0 I want to add three dropdowns at the top to collect Hour, Minutes and Seconds.What I required to load dropdown menus on runtime with values:
Im creating a web application in asp.net visual studio 2008.. in my application, i have manually created a menu control.. since, the menus changes by needs, i wish to load it dynamically from sql table..simple application which loads a menu control dynamically and i can develop mine using those concepts.
Does anyone out there use ComponentOne's C1Menu and create a menu with subitems at runtime? I have went through their forums and help and anything at runtime is done with C1WebMenu which was replaced with this version.I need to create the whole menu with subitems. Can you show code for this if you have?
I designed a simple site with some css and jquery. All the css is in the header using and the javascript files are in a folder called Scripts and referenced in my site like below. Everything is beautiful locally, but on the server some objects such as a couple of my divs are out of their original positions, and my dropdown menus that use jquery don't work properly but they do work somewhat (like they slide down or fade). I have made identical folder structure in root on the web server. I am using .NET 3.5 and the server does support it.
Do you guys think it can be a path issue for my scripts? What could cause the css to move divs out of position? Does css or jquery behave differently on different servers?
creating a dropdown similar to the time dropdown in outlook, located in the recurring event. The dropdown shows intervals of 30 minutes based on a 12 hour time format and allows the ability to put text in it.
I don't want to link my dropdownlists with a database like most of tutorials and forums show. I just want to link 2 dropdownlists, for instance if one says "Food" I want to show only the food producs in the other DropDownList. All this items are not from a database, I just inserted them in the DropDownList control.

I tried cascading dropdown in asp.net using ajax. I have tried with 3 dropdown control.

I'm trying to follow this article on cascading dropdown list in a GridView control in edit mode (except I'm using C#) [URL] I keep getting this error message "ProjectID is neither a DataColumn nor a DataRelation for table DefaultView."
and this aspx page [Code].... perhaps i followed this example here http://programming.top54u.com/post/AJAX-Cascading-Dropdown-Example-using-SQL-Database.aspx
it return an error that System.InvalidCastException: unable to cast di object of 'AjaxControlToolkit.CascadingDropDown' on tye 'System.Web.UI.WebControls.DropDownList'.
Suppose parent dropdown is car (Values are car1, car2, car3)and its child is color(for car1 R Y G B, For car2 R Yand for car3 G B).Now on selection of car2 R and Y will appear and select R, then again made the change on car and select car3 then again select is comiing with G and B and select B.
Now if I select again in car, car1 then the child is populating with the values of car1 but it takes the B as a default value as it was previously selected and also present for car1 too.This case is only happen. on select of child value which is availble for both parent selection.
I have a form that needs to display 3 dropdown lists, one for my client type, then, based on the selection, my second list shows the clients for that type, and then based on the client name, my third dropdown box shows the contacts for that client. The first dropdown list one being a normal html.dropdownlist, and the other 2 being CascadingDropdownLists.
I have followed Stephen Walther's method 1 located at [URL]. If I select my client type, then my client names in my second dropdown shows perfectly, but when I choose my client name, the third dropdown does not work. When I view my page source, all my contacts are listed in my <select> control, but my dropdown box stays blank. Did anyone ever get a third dropdown to work?
I have a cascading dropdown which is dynamically created and does a postback based on a certain condition. How do i set the selected value after the postback
A form contains 2 cascading dropdowns. When an item is selected in the first dropdown, jQuery retrieves a list (json) from the server and fills the 2nd dropdown.
The user posts the page to the server, and when the page is returned the dropdown is empty because its not stored in viewstate.
What do you do in this situation? Is this the point where cascading dropdowns using jQuery and trying to make your page a little more stateless gets tedious?
