Jun 25, 2012
how can I manipulate 1 dropdownlist over another dropdownlist. Example:
I have a product table, which contain the type of the product (eg: FTW, APP, EQP)By choosing the product type, another dropdownlist will give the products under the selected type.
Protected Sub ddlDivision_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles ddlDivision.SelectedIndexChanged
'***************************
'After product type been selected.
'***************************
'use appilication connection
str_sql_user_select = "SELECT article_no, item_desc, brand_name, age_grp_name, cat_name, sub_cat_name FROM view_produk_details WHERE div_name='" & ddlDivision.SelectedItem.Text & "'"
Dim myConnection As SqlConnection = New SqlConnection(dbpath)
I have a gridview with 3 nested dropdownlists in one cell on edit like this:To get the exact fields when the user clicks on edit I used the following code(yes it's messy)
[Code]....
The BLLOnderhoud is a class and the getReserveInfo is used to get the Model - Brand(merk) Information.Since the dropdownlists are nested in the gridview I can't call them directly and they can't call any of my functions.And this is the problem, when I change the dropdownfield Model the Auto field wich is the last dropdown(in the picture is a typo) should be binded like in the following code:
[Code]....
But the dropdownlist onDataBound event can't call any of my functions that are in my class.So my question is how can the onDataBound event of the second dropbox trigger a function? The only thing that the function has to do is to bind the 3rd dropdownlist

I am making an application that deals with vehicles. I need two DropDownLists:
Makes: All Vehicle Makes Models: Models that belong to the selected value of the Make DropDownList
How is this done in MVC2? My Idea: Do I use an ajax call when my first list is selected and then pull back the Models to bind to the Model DDL? How would model binding come into play that way? UPDATE I posted what I ended up doing as an answer. It is super simple and works great. You can use a get too if you feel so inclined, but you have to specify that you want to like so... return Json(citiesList, JsonRequestBehavior.AllowGet);
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 having a 2 dropdown list, in the first dropdown I have 3company names,for each company I am having separate tables,every table have a empcode, if the user select the company name in the 1st dropdownlist, as per company selected the 2nd dropdownlist it will fill the list of employee codes as per the selection..
I am using 3 dropdown list in a gridview and the values for the dropdownlist is dynamic from database.based on first dropdown list selected value the values must fill to second dropdown and based on second dropdownlist selected value then items should load to 3rd dropdown and same for 4th dropdown list. Here if i select age,gender,sex, fist name, last name from the template name Human. The first drop down only populate the fields like Age,gender,Sex and so on., When the second dropdown list populate from the fields corresponding Template name Human, Finance, and so on.
I am trying to develop a simple MVC 2 timesheet application for my small business. I have a sort of mock model for now until I have a database in place, just to make things simpler while I develop the functionality.
[Code]....
But then I need to populate a second dropdownlist (taskDropDownList for the tasks associated with a particular customer) based on the selection the user chooses in the customer dropdownlist. But how do I do this exactly? I have seen examples with jQuery, but I'm not sure how to apply them to this situation. Also, the examples seem to just populate the lists with string values. I need to be able to access the objects with all their properties. Because the next thing I need to do is to be able to populate the TimeSegments list of the selected task with values from input fields (i.e. the hours worked for particular dates). And for that to be saved to the "model" (eventually to the database) in the controller, how do I get it there, unless the objects are all part of the same model bound to the View? I'm on rather thin ice with this since I still find the connection between the View and the Controller hard to handle, compared with e.g. Windows development, where these things are rather easy to do.
