AJAX :: Using Any Textboxes In Any Of Web Forms To Generate A Postack In An Update?

Jun 16, 2010

With a VB WEb app, using VS 2010 and all updates, I have been getting intermittend javascript errors. Finally tracked it down to something to do with textboxes and update panels. With-in any of my Web pages, if I use a textbox and the .TextChanged even to post back, I get a JavaScript error. No problem if I use a Dropdownlist, Button, etc. Also, if I use any other controls such as buttons or dropdownlists before using any of the textboxes to generate a postback, everything works fine.

And yes, I have the the controls with-in the correct updae panels just in case anyone was wandering.

I wasn't having a problem before and have a feeling it is a bug, but am not sure so I posted it here.

Also, can't figure out how to debug the Javascript code. Using the developers tools in Internet Explorere it says soure code doesnt' exist for some reason now.

Generate Dynamic TextBoxes Based On Count Value In QueryString

Jul 9, 2012

Suppose, I sent a value from 1 page to another [ex:5]  then on another page where i sent the value I want to display that many TextBoxes 1 by 1 means 5. I want to read all the values and want to store it.

 Once the another page got the number It will display :-

Enter Product 1 Quantity : TextBox1 : I will enter the quanity next

Enter Product 2 Quantity : TextBox2 : I will enter the quanity next

till TextBox 5 / number

Basically, my idea is I want to generate the bill according to products which my worker carry. So I will enter my worker id and I will ask him how many products do you have. I enter the number. suppose 5. then that many textboxes will appear on the form and i will just enter there quantity.

MVC :: URLs - Using GUIDS & Non Unique Names?

Mar 12, 2010

I have a question about URLS, I am creating a little app and using GUIDs from the primary key and identity and LINQ2SQL - So wondering how I would go about creating nice URLS? I don't want the guid in the URL which is what it tries to do by default.And I can't use a Name field as there may be duplicate names? I'm considering just creating another auto incrementing field in the table just for the URLs? Just wondering how everyone else handles this

Web Forms :: Controlling Focus On Form With AutoPostBack TextBoxes?

Oct 29, 2010

I have a form with several textboxes. All of these have AutoPostBack="True".

My problem is that the focus disappears to goodness knows where after each postback. The behaviour I would like to enforce is as follows,

If the user hits the Enter or Tab key after filling in a textbox then the focus should go to the next field on the form (to be explicitly specified in my code).

If the user clicks on textbox X after filling in textbox A then the focus should go to textbox X after postback, even if it is not the next in the list.

In other words, I want the form to behave in the way that most users would intuitively expect.

I have Googled for potential solutions to the loss of focus after postback but the few that I have found were many years old and I am unsure that the advice is still relevant for ASP.NET 4.0. Some of these old solutions also appeared to be invalid for browsers other than IE. What is the current best practice for handling this issue?

BTW, VB.NET solutions are preferred though I will also be happy to accept C# suggestions (which I would run through a code converter). Note that I have a single sub in my code for handling the TextChanged events for all my textboxes. This means that I have to use the following code to work with the textbox that has called the sub.

Dim CurrentTextBox
TextBox =

If addressing the focus problem means that I have to have individual TextChanged event subs for each textbox then so be it, but I prefer the simplicity of my current single sub approach.

Web Forms :: Method Wont' Accept Input Form Textboxes

Jan 21, 2010

I've written a small class .That has a method for adding and subtracting.

My class file is fine and everything works well when I hard code the integer values. But the moment I try to use textboxes in my methods signature to accept values it complains that this is an inavlid argument. I assume that this is because I used int as my signatures but then how can i use my class to textboxes as input.

Forms Data Controls :: Repeater Textboxes - Unable To Fetch The Values Of Textboxes

Aug 11, 2010

I have a repeater which is binded using a Collection of Entity Data Framework.

Once the repeater is binded using the datasource, the user can control the no of rows present in the repeater using a Dropdown list on the page. For ex: if datasource has 2 rows, user want to add 3 more rows, user selects 5 from dropdown, which adds 3 additional rows to the Repeater. I am able to do this.

The repeater has textbox controls in each row. Now once the user enter the values in this textbox of the newly generated rows, the user can save the values entered with the no of rows specified.

I have a button which is outside the repeater and on click of this i need to validate all the textbox values and save them into dB accordingly.

Here is my code






Right now the problem is im not able to fetch the values of the textboxes present in the newly generated rows.
