Data Controls :: Bind Cascading Dropdownlist To Show State And City Which Is Stored In Table
Apr 27, 2016
Into my application there is EditAds.aspx page where the user get a link on his email after he add an Ad into my application. My inquiry is can i bind the cascading ddl to show the value of State column into Ad/product row as well if the user want to update the rest of state will be also reachable. It maybe hard to get what i am looking for exactly so i make a short screen record ...
Rebinding values of Ad/product depending on AdsID which is  a query string in the page called: QADNUM
[URL] ....
if (!IsPostBack)
{
if (cookie["Location"] == null)

DataTable rEfilterstathpBizDT = new DataTable();

Using four dropdown lists (country, state, city, pincode) in one table. i want to select one after other like based upon the country, states has to be displayed and based upon the states, cities has to be displayed and based upon the cities , pincode has to display.Â
Now i'm working on the cascading dropdownlist for to bind a country and city, city is based on country dropdownlist. its working well , if city comes more than 8000 records in city dropdownlist , takes more to bind city.
I have a scenario where I need 2 dropdowns like state and city.City dropdown depands upon on State drop down.Will you please tell me how to achieve it ASP.NET MVC?I found this article but not sure is there any alternate way to do?http://stephenwalther.com/blog/archive/2008/09/07/asp-net-mvc-tip-41-creating-cascading-dropdown-lists-with-ajax.aspx
Here is my scenario.In default.aspx page user selects the country, state, city from drop down list, and store them in cache for further use. but when other user open the web site from other computer it shows the same country, state, and city selected by user 1. Is there any problem related to cache? I have stored data as following.
cache["ctryID"] = ctryID;
cache["stateID"]= stateID;
cache["cityID"]= cityID;
I want to show default country, state , city at page load of default.aspx
retrieving values related to user select a country then its automatically shows the states name of that country in next dropdownlist and after that it will automatically display the city names respected to that country.
Girdview has dropdownlist TemplateField called ddlSate, how to bind state field value in sql table to selected value of ddlState dropdownlist control? For example the sql table has AL value for state field, (Note by default ddlState lists all states options with sqldatasource), how AL is selected in ddlState when binding to ddlState?
Secondly, when user selects different state like GA, how below update stored precedure works? that means how to find ddl selected value in update procedure as shown below question mark line:
I have a cascading dropdownlist. The first drop down is for Departments and is databound on PageLoad from the database. The user then selects a department and the second dropdown is populated with the appropriate sub departments via JQuery/JSON which calls an httphandler. The problem is as follows: I select a department and the subdepartments are filled.
I finish what I'm doing on that screen and everything is fine. But then if I go to a different screen and add an additional subdepartment then come back to original screen, the new sub department won't appear in the cascading dropdown. I have to close the browser and restart the session in order for any new sub departments to appear even though they are in the database. I put a breakpoint in the httphandler and noticed that it is only called once per session per each department in the first dropdown. I don't know why this is happening. I want it to call the httphander EVERY time the index of the department dropdown is changed.
I have a GridView control that has a SQLDataSource.
The GridView provides me with a list of musical artists (from the tblArtists)
In the Grid, I have a field, FKGenreID, that is a Foreign Key value for music Genres.
(An example of the data in that field would be "7", which upon lookup would mean Classical in the tblGenreList table.)
What I'd like to do is add a DropDownList control that looks up the tblGenreList table and populates the DropDownList with the ID and Description from the tblGenreList Lookup table.
Now the tricky part is that if the GridView field (FKGenreID) has a value, then I'd like the corresponding Genre Description to be displayed in the DropDownList
Alternately, if there is no value for FKGenreID in the GridView, then I'd like the DropDownList to show that nothing was selected, but have the list of Genres available.
Most importantly here, when the user makes a selection, I'd like the GenreID (from the DropDownList) to be entered into the FKGenreID field in the GridView field.
My thought is that a gridview record may or may not have a value in the FKGenreID field. Either way, the DropDownList is bound to that field. The DropDownList would display a list ofGenre Descriptions for the user to select from. Upon selection, the GenreID column of the DropDownList becomes the value in for the FKGenreID field in the GridView.
Is this possible?
In case it matters, I'm using ASP.NET 4, Visual Studio 2010, and coding in VB
Which one is faster? For a dropdownlist binding it the first time and using ViewSate or Turning of viewstate, keeping the data in a static datatable and binding the dropdownlist each time on a postback
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.

I bind ddlTrade from Tradetable and I want when users click on Item from ddlTrade it bind data from ddlTradeclass that TNAME=ddlTrade.selectedItem in ddltradeClass for this I used below code
I have 2 dropdownlists and on change 1st dropdownlist (ddlPlant), the 2nd dropdownlist (ddlCategoryName) refreshes its data based on 1st dropdownlist value. However, the codes does not worked.
I have created two dropdown lists. The 2nd DDL depends for values on the 1st DDL. I have written code on the SelectedIndexChanged event of 1st DDL to change values of 2nd DDL. also i have used detailsview. In the template field i have used 2 DDL mentioned above. they are having SelectedValue='<%# Bind("") %>' property. Everything works fine but when i tried to edit record in detailsview & select value from 1st DDL then it gives me following error.
Server Error in '/' Application. Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
I have an ASP.NET/C# web project that uses an Entity Data Model and Entity Framework to interact with my database. I also have a DetailsView control that will serve as the control used to insert a new record. The user will need to be able to select from multiple, cascading dropdownlist controls to determine what parent record this new record will belong to. Here is an example.Say we have an online ordering system with the following hierarchy.
Customers -> Orders -> OrderParts -> Parts
We're going to add a new part to an order, under a customer. Ultimately the orderparts table won't have a reference to a customer, just an order. The order will have the reference to the customer. In the DetailsView for the new orderparts record we will need two cascading dropdownlist controls. One for customer and one for order, since we won't want to view some crazy amount of orders all in one dropdownlist.
However, the customer dropdownlist should not be bound to the detailsview control since there is no field for it. I also don't want to use the AJAX control since I don't want to create a separate web service to provide all of this information to the dropdownlist controls.
