I have a dropdown list placed in Update Panel the issue is that when i am trying to make selection from the dropdownlist i am not able to select the items under it(i.e. after clicking on the dropdownlist the items get displayed but when i move the mouse over it the dropdownlist gets closed).
This issue is observed in Fire Fox only (works fine in IE and Google Chrome).
I have two ListBox in my ascx file, I fill them with some data (no problem here), I make them multiple and increase the size, below is my code.
I use some jQuery code to exchange element between them (Here too, no problem). My problem begin when I post my form, I'm unable to get the data from the DropDownList with attribute multiple or size. I tried in my controler to add a FormCollection parameter, I can see every element in my form except those select tag with more options than id and name. I tested to put a manual select tag in my code with only an id and a name then add size and multiple attribute, when there is only id and name I can get the value but when there are more I can't get my select tag in the FormCollection
Also I need to get all the value in the ListBoxand not only the ones who were selected. I have been searching answer for 2 fays now... Without success, I only find resource on how to show ListBoxbut not how to get values from them in mvc web site and I don't find any resources who talk about multiple selection ListBox, I think I'm a bad searcher but....

I am having two dropdownlist in my project,one dropdownlist for empid, another dropdownlist for month, if the user select the empid, the values are retrieved in the textbox.
In the second dropdownlist, if the user select the month in the dropdownlist it will display the leave details, its all working fine, if the user again select the first dropdownlist that means empid, I want to show the second dropdownlist as select month, how can do this.....
I have a dropdownlist on my page with dates such as 1/1/2013, 2/1/2013, etc.
Then there is a second ddl.
If the date in ddl #1 is before 1/10/2013 I want to enable ddl #2. If the date in ddl #1 is on or after 1/10/2013 I want to either disable ddl #2 or hide it (whichever's easier).
Disabling ddl #2 based on the selected date is a new requirement so I am enhancing the existing code. Obviously I want to do this without a postback, but I don't know what is the best way. I am trying to understand what an AsyncPostBackTrigger is because this is the existing code:
I am using the cascading dropdownlist controls from the Ajax toolkit. I have everything working perfectly and all of my select changes work. I have 3 related select boxes that all work great for single item select. What I need is for my last dropdownlist to allow for the selection of multiple items. I have tried adding the 'multiple' attribute to the final dropdown list and it allows the selection of multiple items but I cannot get the items when I post back, just a single item.
I have a page that searches and displays records. Users enter a record number and then select the type of record to display from a dropdownlist control. They then edit some data on the page, and the app does some calculations based on the type of record that is selected from the drop down. How do i get to successfully pass the value from the dropdownlist to the method that does the calculation to ensure that the right formula is used? Here is the code that I currently have.
then the code behind to do the calculation looks like this...
After stepping through the code, i noticed that when it gets to the "foreach" block, the value selected by the ddlRecordType dropdownlist is always the default which is "select one" and not any of the other selections that might have been selected.How do I get this to work, so that it can maintain the value selected from the dropdown and used in the code behind?
I want to make a single selection in radiobutton in a gridview. I have added "GroupName" in radiobutton attributes but it only works in column which suppose to have a single selection in the entrire gridview. Another problem is getting the value of the radio button. Selected radio button value must appear in a textbox once it was clicked/checked.
I have a list box that I want to allow the users to select up to 4 items from. I set the selection property to multiple, but for the life of me it won't allow multiple selection. If I pre-select 4 items, they show up as all selected when the page loads, but as soon as I select another, it clears all of them and then only allows one at a time. if I check the source code for the page, the property is set to multiple (see below).
I've got two DropDownLists that are filled using a couple of SqlDataSources, like so:
The third DataSource, dsCriterias, is used to present a set of dynamically added DropDownLists depening on what's selected in the second DropDownList, subcategories. The set of dynamic DropDownLists are presented using this code:
The code works but there's little thing that's bugging me. When the page is first loaded the criterias belonging to the subcategory is not presented. I expect it to show the criterias but ther won't show until I make a choice in the categories-DropDownList meaning if I wan't the first subcategories criterias I have to choose different subcategory and then go back to the first one. It's a bit hard to explain.
An example: When the page is first loaded I get a category presented, eg. Vehicles. In the subcategories I get the alternatives "Bicycles", "Cars" and "Motorcycles". "Bicycles" will be the one presented when the page loads since the stored procedure used by dsSubcategories sorts the data by the subcategory names. The problem is that I don't get the criterias for the "Bicycles" subcategory at page load. To get them I first need to select "Cars" or "Motorcycles" and then choose "Bicycles".
I've tried putting a subcategories.SelectedIndex = 0 in in the OnLoad but nothing seems to do the trick.
I have already spent two day to solve this on my own but for some reason I can't. Maybe I'm missing the live cicle of the dropdownlist. I hve a three dropdownlist that filter a gridview and the other two dropdownlists One is "Year" the other is "Country" and the other "Species" Each one of them is filter by the other two. So if I filter for one year it will only show me the species and countries that have records on that year. So I have to reload the gridview and all the dropdownlist.
What happend is that since I'm filling again the dropdownlist with less values he can't remember the previous one. I have tried with the events: DataBinding, Load Unload and Init of the dropdown list to force it to remember. The conclusion I have reach is that the databinding and the load have the dropdown list of the previous page. So if I do
I have been having some trouble with dropdown lists reverting back to selecting the initial item in the list after a postback once a selection has been made from the dropdown list. I have read up on this and found out that a "if not ispostback then" is required.This works fine when I add in all the items in the dropdown list manually like:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not IsPostBack Then ddl1.Items.Add("Select...") [code]....
However, I have over 250 items and so it is far more efficient for me to load then in by using part of a multidimensional array which is created from a text file - Definitive database.txt. I have been using the following code to do so:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not IsPostBack Then 'loads the definitive database array[code]...
This loads all the items into the dropdown list perfectly, but now every time a selection is made, it reverts back to the inital item on postback even though i have included the "if not ispostback then" part.
I have the following code, i add code for required validator, but when you make selection from dropdown to create the table, the page generates an error. Should the logic be somewhere else to add it to the table? i mean, dont they have to be there so when you submit the form, it fires the validation?
I have one asp.net dropdownlist which consist A,B values. If user Select A in dropdownlist i need to bind this query to Gridview. Select FirstSelection from Tablname else Select SecondSelection from Tablename. How to do so..?
