I have a table in SQL Server which gives me a list of products (PRODUCT), and the products category (CAT). Right now I am putting all the products in the same ListBox:
But I need to create as many listboxes as there are categories, and distribute those products according to the category. Categories might be added or removed so I need to create them dynamically. So lets say the table has 5 products in category 1, 4 products in category 2 and 7 products in category 3, I would need 3 Listboxes created. The first with 5 items, the second with 4 and the last one with 7 items
I want to create multiple listboxes when you select the first it does a database query which gets a list for the second list box and it carries on for the third and so on. Beside each list box is a form to insert an entry for that list is there an article or video on how to do this. Some ajax might be needed to do what I want Im not really sure what to do I can't find an article on this.
I am developing an mvc 2 application.In my form i have a listbox. Based on selecting the items in the listbox a vertical tab is created.the tabs in the vertical tabs are created corresponding to each item selected in the listbox.after the creation of the vetical tabs each vertical tab will be containing a listbox.here the user can select the list items.now my problem is that i want to know which all items in each listbox in each tab is been selected .some code:
I have three ListBoxes each representing a single field database table. They are presented side by side on the ASP.NET page. Is there any way to group them so that only a single item from any of the boxes can be selected at a time?edit - ie, if item 3 in box 1 is selected, selecting any item in box 2 must unselect it
I'm currently in the process of creating a webshop. This webshop supports theming, but I also want customers to choose a lay-out. I can create multiple masterpages and create a handler to dynamically set the correct master page. But some components, like the shopping cart, are controls which have to be present in the master page and are also used in the aspx pages. The shopping cart control for instance, has an Update method which is called whenever the user adds a product to their cart. So the question is: can I somehow create a default masterpage which has all the components on it, but still be able to create multiple lay-outs. And how should I reference that master page from the aspx pages? I also thought of creating an Interface class which defines the masterpage and it's public components, but I don't know if I can reference an interface from aspx pages.
I hope this is in the right sections....if not please feel free to move it. Does anyone here have examples of how to create multiple text boxes dynamically based on a search result? For example A table has 5 rows. how do I output to the screen 5 text boxes? and then get their details later? (so in a week if there are 15 rows in the table , then 15 text boxes are output) also what would be a good search term on Google for this so I can try and find other examples as the search terms i was using returned zip
I have a listview that displays a list of textboxes that get created on a button click. I would also like a label to be created next to each txtbox that would increment what is says from step x: to step x+1:
Do I need to create another listview control for this, or is there a much easier way (which I hope)?
Here is the current web code for my listview:
<tr align="center" valign="middle"> <td> <asp:ListView ID="lvDynamicTextboxes" runat="server" ItemPlaceholderID="itemPlaceholder" onitemdatabound="lvDynamicTextboxes_ItemDataBound">[code].... And here is the code-behind
These textboxes are to create steps in a process, so all I would like to do is add a generated label next to each generated textbox to say which step it is. So I want it to look like this:
Im using Microsoft Expression Web 3 and am in the process of making a page for my Cab Company that basically calculates the price from an area in London (In listbox A) and an airport (In listbox B) along with the type of car used (Saloon, Estate, MPV) in a checkbox list.
If I were to set a value for each and every item in Listboxes A, B and Cars, is there some sort of autosum code I can use which calculates the price. The feature is only going to be a pricequote system for now untill we get some sort of booking system up and running so it is preferred that all calculations are done & displayed on the same page.
I have 2 listboxes, when i add a item retrieved from database to Listbox1, i need to select the item and bring it to listbox2. But i do not want to have same records added again. In my case, i cannot use the codes below
[Code]....
because the text displayed on listbox1 and after transferring to listbox2 are different. So i come out with a logic which is "if listbox2 does not contain the item value in listbox1 then populate listbox2". So i tried the codes below, but it is not working as there are errors
I have a web app that has two listboxes on the page. The first listbox has selection items that can be chosen and moved over with back and forward buttons to the destination listbox.
I can't figure out how to validate the destination listbox for empty items on a postback. I have tried to use a custom validator, but I can't get the validator to fire unless I actually select one of the items with the mouse.
I am trying to design my logic to do this but I want to create a dataSet which will have records from several databases, The records all have the same layout.
I am reagin the connection string paths from a table in a database.
I am asking for your help in trying figure out my logic.
Should I use the connectionString builder in conjunction with a loop to Connect, read a record into a dataset Until therer are no more records to be read from my databse table with the database name/paths tables ?
Here is my beginning code which deals with one database:
I have a form which inserts data in DB on Submit button click but the problem is when client click the button multiple times its sends multiple create requests means multiple button click events for the same time of same data, which must not be.
I tried to disable the button when client click the Submit button first time but after this it does not call server click event handler or not fire the server click event once it got disabled.
I have two drop down listboxes in a GridView control. I want to populate the second drop down listbox based upon the value that was selected in the first drop down listbox. Currently I have not been able to populate the second drop down listbox. I am attempting to do this in the C# code file. See line 26 below.
// Here is some of my Aspx code: this first item template populates the first drop down listbox:
I am creating a web site through command line. I am able to create a web site with single host address. But i want multiple host address for a website. this is the command I am using iisweb /create D:Test Test.com /d [URL]
I have two databound listboxes. I am able to move items between them using add and remove buttons using for loops. However I have no idea how to commit the items back to the db when the user finally clicks on the Save button on the form.
I have two listboxes on one panel. Box on the left has names from the database, there are two buttons. High light a name and click button1 and the name move from listbox1 to listbox2. How do you do that?
I am having a lot of trouble with a seemingly simple thing. In an ASP.NET webform I have two ListBoxes, with Add and Remove buttons in between. The user can select items in one ListBox and using the buttons, swap them around. I do this on the clientside using javascript. I then also have a SAVE button, which I want to process on the server side when the user is happy with their list.
Problems : First I was getting the following problem when I clicked SAVE :
Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. I read that one of the methods to get around this was to put my ListBoxes into an UpdatePanel, which I did, and I am getting further.
However, now the event handler for the button's Click event is not being run if the user has used the clientside javascript to alter the contents of the Listboxes. If the user has not altered the contents of the listboxes, the handler does execute.
Protected Sub btnAddRow7_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddRow7.Click Dim tableRow As New System.Web.UI.WebControls.TableRow Dim tableCell As New System.Web.UI.WebControls.TableCell Dim textBox As New System.Web.UI.WebControls.TextBox tableCell.Controls.Add(textBox) tableRow.Cells.Add(tableCell) tbl7.Rows.Add(tableRow) End Sub
but it only adds one row dynamically. After the first addition, more clicks to the button will not add more rows.
I have 3 text boxes where a user can enter numbers. How do I dynamically add the 3 text boxes and show the sum as a label. I also need to make sure that the user is entering numbers. I am using c# and new to .net programming.
I have a contacts page where I have a table and 6 textboxes and a button(named ADD) in it. Whenever the user clicks on ADD another row with these textboxes and a button(named ADD) should appear.
Initially I thought of creating a table of 10 rows with these textboxes and button and hide them, and when a user clicks on ADD 1 row will be visible BUT whatif they have to enter 200 rows?
So I want to create the rows with these textboxes and button dynamically without any limit like 200 or 300.
I have a simple user control which contains a textbox and a dropdownlist. I need to add this control multiple times to my page then save the details to my db, validating each control. When they re-enter my page I need to load the user control for each record in the db populated with the data they entered. They can then edit the data, delete the row or add new rows.
I'm trying to find the cleanest most efficient way to accomplish this. I realise I would need to re-add the user controls after each postback re-populating the data. Would the best way be to add each row to an arraylist or list of type object, save it to the viewstate and re-add the controls with data on postback, or is there another method which would suit?
I want to create a page that will dynamically change the images displayed, based on which link the user clicked to get there. For example I have different movies listed and when you click a link for one of them it displays all the images for that movie. I need it to be on one page because at the moment I have hundreds of pages and its very hard to manage. I have the images stored in BLOBS on SQL Server 2005. I can retrieve all the images for a certain category and store the Image data for each one into a list of images. What I cant do, is display the images on the page. I can display one image by using the queryString to get the image by ID, then putting the Eval code into an asp:image, but I dont know how to do it for multiple images.
