I have a page where I have 20 textboxes, each indicating a name that I need to go through. Rather than having 20 sets of code, I would rather loop through, something like this:
Code:
[code]....
But it fails to find execute when I hit it, Object reference not set to an instance of an object."
I need to know how to loop the user input value in textboxes programatically. For example I have 3 rows of textboxes i have programatically generated with id txtCategory1, txtCategory2, txtCategory3. Since I generated all these textboxes programatically I have no idea how many textboxes will be there. I need to do a looping again to get the value user put in into textbox. How can I get the value of textbox by using ID?

I have a dropdownlist whose values are int (actually they are string basically but they can be parsed. they are 1, 2, 3, 4, 5.. etc)
I want to create textboxes acording to the number of dropdownlist selected value. Lets say drop down shows 3 and I wanna create 3 textboxes. how can I do that.
In my application I have panel which has 5 textboxes. I've written several functions for checking each of textbox if the entered value is ok (number, is this number in database, etc.). If error occurrs textbox which caused it has different color of background.
However I wanted to write (add) function which will check if one of the textboxes has the same value as other. The problem is that function is checking blank textboxes, although it shouldn't - I wrote if statement which allows checking only non-blank textboxes but it doesn't work.
The repeater below allows a visitor to click a [+] to add a textbox. They can add as many as they need. Each textbox will contain a name.

I want to be able to collect all of the additional textboxes and add it to an string:

If for example the visitor added two textboxes and typed in "Mary" in the first and "Sue" in the second, I'd like "myAdditionalRegistrants" in the above string to be replaced with:
Mary <br /> Sue
Like many people using ASP.NET MVC, I've implemented my own custom 404 error handling scheme using an approach similar to the one described here: [URL]
(I actually discovered that post after implementing my own solution, but what I came up with is virtually identical.)
However, I ran into one issue I'm not sure how to properly handle. Here's what my 404 action in my ErrorController class looks like:
[Code]....
The part that's different from the answer in the other StackOverflow question I referenced above is how the 'retry loop' is prevented. In other other answer, the code that prevents the retry loop simply sets properties on a ViewModel, which doesn't seem to actually prevent the loop. Since the action is sending back a response code of 404, then accessing the action directly (by typing "/Error/NotFound" in the browser) causes an infinite loop.
So here's my question: Did I miss another, more obvious way to handle the retry loop issue, or is my approach a decent way to do this?

View 3 RepliesI have a userControl with with two DDLs and two RBLs, and public properties to get/set the values. If I register the UC on a page it works fine....I can set/retrieve the values without a problem.
I need to create multiple UCs based on records I'm pulling from a dB, so I'm trying to instead create the UCs programmatically. I'm testing this by adding a reference to the control ("symptomBasic"), creating a placeholder ("ph1") on a page and then trying to populate it with the UCs in PageInit. (the parent page uses a master page)
Partial Class testUC
Inherits System.Web.UI.Page
Private myUC As ASP.symptomBasic
Protected Sub Page_init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
Dim i As Integer
For i = 1 To 3
myUC = CType(LoadControl("~/controls/symptom.ascx"), ASP.symptomBasic)
ph1.Controls.Add(myUC)
Next
End Sub
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub
End Class
When I load the page, I get three UCs in a row, and they work properly on postback...i.e. all the values are preserved. Question is, how do I then find the controls on postback when I want to populate them with data or read the values back?
Let's say I know I returned 3 rows from the dB and created 3 UCs during pageInit...how do I then access those controls to read back the values provided by the user? I see that each control has an ID like: "ctl00_ContentPlaceHolder1_ctl01_cName", where each set of controls is "ctl00", "ctl01", etc.

How I can do it
I have several rows in my database like this
ID Status Type Count Event
291 0 0 2 1
523 1 2 0 4
and so on. When my user performs some basic actions on my website, some values are passed through JSON to the server and are then converted into custom objects with 5 int properties(so they match the table). These objects that the server receives are the rows to be updated(based on ID) and the values for each column. How can I do this in one SQL statement without the need to loop through each object and update them all seperately? Is there a way? Preferably compatible with SQLServer 2005.

Using a loop to send multiple e-mails with alternate views
I'm trying to make a form that could have one or multiple textboxes. I have a textbox and a button to add additional textboxes.
I have no problem adding a second textbox inside a panel but I want to be able to keep adding more textboxes every time the link button is clicked and later reference those boxes to be saved. I would also like to maintain the value of the textboxes there. They are not saved to the database until all the necesary texboxes have been added.
I added the textbox using:
private void button1_Click(Object sender, System.EventArgs e)
{
TextBox textbox1 = new TextBox();
panel.controls.add(textbox1);
}
that works fine, but when i click the button again it doesn't add an additional textbox which is what i need.
I have a form containing fields for a user to enter an address. The town/city field in the form uses an autocomplete extender to return a list of suggested towns/citys which are taken from an sql query in my webservice. The table in the sql db that contains the addresses also has a column containing partial postcodes for those places.
What I would like to be able to do is have it so that when the user selects a town/city from the autocomplete list or types a town/city in the textbox, it triggers another query to get the postcode from the db and updates the postcode textbox without a full postback.Is there an easy way to achieve this? I know there's the OnTextChanged event for a textbox but this is server side isn't it so would only trigger on postback? Could you have two auto complete extenders and two webmethods where the value from method one updates textbox one and method two gets the value from method one and updates textbox two?
