I have created a dynamic table using user entered values for Rows and columns. After the table is created the data is populated on the table. I have a separate event that is clicked to retrieve this data, but I am not able to get this data upon postback.
I need to convert the table values (in int) to an array for further processing.
I have a page where I would like to collect information about x number of users. I have a control where you enter in the number of users and based off of that number, I create a dynamic table with a row for each user. Each table row has textbox controls that I would like to retrieve the value from on postback. How can this be accomplished?

How to use this scenario with a single GridView table?
Based on the User input, the GridView might have (1 + 3) columns; (1 + 6) columns; (1 + 9) columns; ...etc.
a pure html table will be generated on the client side. (using jQuery to add dynamic new rows to the table when the user clicks a button).
These rows contain textboxes, dropdownlists, checkboxes and other input controls.
When the user clicks a button, a PostBack is triggered in which I need to access this data from the table on the server side, validate it (yes all rows at once) and perform other actions on it.
I'm able to perform the client side and access the table data on server side by adding runat="server" to the table tag. However, I only see the initial table rows (not the ones added through JavaScript) and I have troubles retrieving the different inputs from the rows.
I have a webform will perform a server.transfer to another webform. Upon postback on the second webform, i am not able to retrieve the previouspage data. is there anyway i can achieve this?

I´m looking for some advice on how to create an table showing bookings, a table containing mon-sun on the horizontal axis and times at the vertical. The admin is able to edit each days bookable times (first bookable time, last bookable time) - The slottime is constant.
What I want is let the admin click on eacha cell to remove it/add it when removed. And other features as well, like create an booking for a customer.
What would be the easiest way to achive this, at the moment I use dynamic links since I cant get asp:buttons to work and the code to create an dynamic asp:table row by row and this produces some ugly code.
So any advice on how to achive such an "schedule".
I am creating a kind of feedback website which has a feedback form on it. Each question is answered choosing from a radio button group. the answers to each question are (very good, good, bad, failed). I need to be able to create a table on the webform that will display the number of answers to each questions. for example, if the question is "Rate the use of this software" i need to be able to put in table format say 20 people said "very good", 30 said "good" etc. at the moment i only have one table to display the questions and answers and a date that will be used to select the date's report. so all the information i need is coming from this table. all i need to do is how to say like "SELECT Count* Question where Review date = "user entered date" and answer = "very good" etc.

I have a profile of member to be displayed. I am using a dataset with all the data table adapter to retrieve the information from database.
I have a memContact method which has NRIC and Number as a composition primary key. Thus, automatically, the table adapter has created a method called FindByICNum () for me. However, when I do the search to display the contents, i will only need to search by memberic instead.
Is there anyway to change the table adapter query?

have an ASP.net 4.0 page containing a GridView, where during the Page_Init event I'm dynamically adding BoundField columns to the gridview. I also have some custom sorting and paging methods that I use with this gridview, which result in postbacks on the page. In Chrome, Firefox, Safari, and Opera the gridview behaves as expected. HOWEVER, in IE 6, 7, or 8 when I click to sort a column in the gridview, or go to the next page of results in the gridview, it does not bind on postback, returning nothing back to the browser. Again, in anything but Internet Explorer, paging and sorting (frankly any postback event) brings back the gridview in its expected state. I only have the problem in IE. Relevant snippets of my code follow, where you'll see my Page_Init event calling a method in my WebFunctions class to add the BoundField columns for the table I pass to it, and my Page_Load event that calls the method in the user control responsible for binding my dataset to the gridview. Initial page load works in all browsers, but postback loading of the gridview only works in non-IE browsers.

how to retieve images which are stored in database one by one and put them in webpage's table.
My project is shopping cart type project in asp.net and server is sql2003
I saved the image urls in database.
(Example code below)
I have a GridView. It has a 'static' TemplateField (in the .aspx page). I add and remove BoundFields to it depending on user preferences on postback. Affter the second postback, the template field appears empty.
Here is a stripped down mockup of what I'm doing. You can click the "Regular Postback" button as much as you want, and nothing bad happens. But if you click the "Recreate" button once-- it's all ok. Click it again, and the "one" column goes on Christmas break.
So is there something else I should be doing, or is this going to be a "halcyon1234 to code interface" error.

I have a web page with a GridView and a table outside the gridview to display more information of the record when it is selected (like record details). I'm using data of five tables for this particularly window. I use one table of the five to bind the gridview the other tables are for the details, but I use like 1 or 2 fields of those tables. I'm binding the page with web services. I need some advice on which is the better way for doing this to make a faster web page.
In sql server I made a view with the five tables (all the tables relations are working perfectly). In the web service I call the view; and in the web page I call the web service to bind the page. Everything is working. All I want to do is retrieve from the server all the necessary data only once when the page loads and bind the five tables data (like 18 fields total) in the gridview which I only show 12 fields the other 6 fields are hidden, those 6 are for the details which I get with jQuery (that's another topic). Bind everything only once and manage the data on client side. Everything is working perfectly. Here is my doubt.
How are the maximum table joins I can make? To retrieve the data via web and not get a server time out error. Which is a better way to make a faster page? Make 2 views one for the gridview and one for the details and put each view in a web service; or make one view with all the table joins and one web service. Right now all is working but I have to make other pages that use different tables and joins and I don't know if the server gets me the time out error when the page is fully working.
I have a dynamic table in my view. The table is used to enter data about items, the number for which is not known. The the user can add any number of rows to the table. The script is plain javascript.
Questions:
1. Right now a normal textbox and dropdown is added to each row using the javascript. How can I add a html helper control instead so that I can get the viewdata values.
2. The model contains a List<T> as a property. So, the dropdown control id is named as an array. Eg: item[0].type, item[1].typeThe problem is this dropdown is populated by data from viewdata. How can I add the data for an array thru viewdata. Remember the number of items is not known
