Web Forms :: Duplicate Number Validations In Dynamic Textboxes?
Nov 30, 2010
In one of my aspx pages, i have dynamic built textboxes, each having its own unique id. These textboxes have to accept numbers 1,2..n. There can be any number of dynamic textboxes. There is a save button as well on the form, which is static. OnClick of the Save button, i have to highlight the textboxes that have duplicate numbers.
There is a bad way to achieve this by iterating through these dynamic textboxes and one-by-one comparing each textbox's value with others, but this will result in performance issues.

In my form i am having 5 text boxes where onlyone text box will be active(visible=true) and i need validation for it.....Similarly i applied the same validation for all other hidden textboxes which will be activated by another add button click.So here am having only one button to submit the data basing on the user selection of textboxes.So while submitting data in single in textboxes validation is firing in another textboxes also and I dont want it...i want the validation to be fired for the textbox which i activated it.

I am generating dynamic textboxes with the ids as follows table row 1:
no1,name1,addressline11,addressline21,city,pin,communicationAddress1(here the row count I am appending at last to the control id's)table row 2: no2,name2,addressline12,addressline22,city,pin,communicationaddress2
table row 3: no3,name3,addressline13,addressline23,city,pin,communicationaddress3 and so on....
A new will be created when user hits enter key in the last textbox i.e., communicationaddress.For validations I have used java script. Now my requirement is when user types the address line the content of the textbox should be copied to communication address.
communication address = addressline1+addressline2+city+pin
so in theabove four textboxes when the user hits the keys the matter appending to the communication address with ',' seperated. I acheived this through key press event in java script..................

my problem is that i have a dynamic controls(text boxes) that are generated depending on a dropdownlist
and upon generating the textboxes i have created a required field validator and associated it to the text box that is being generated,
when javascript is enabled in my browser, the client side validation works fine, but when i disable the javascript.. no server side validation occurs and the Page.IsValid gives true when the method Page.validate() is fired
i tried a new simple page with dynamic controls and seems to work fine, but i could not figure out whats wrong with this page.
private void generateFarmForm()
{
int numberOfFields = 9;
Label[] labels = new Label[numberOfFields];
TextBox[] farmt = new TextBox[numberOfFields];
[Code]....
also the button that submits the form back has the same validation group,,, yet no luck with this... the page is in a content tag of a master page if this has any relation to the problem

I am building an application using masterpages, one of the pages contains dynamic gridviews with textboxes using templates. The textboxes have the autopostback enables to allow the calculation of the numeric values entered in each row.
The grid has 3 cols (3rd col has the total of the first and sec cols) the problem is that when i change the textbox (therefore a postback is created) the page scrolls up.
I tried the Page.MaintainScrollPositionOnPostBack = True but it does not work. Can i use any other method to solve this poblem.?

I have a multiview page. Page 1 basically gives you the option of selecting if you want to enter percentages or amounts. Page 2 you can select a productgroup page 3 creates dynamically a table with textboxes in the first row and radiobuttons in the next rows. In the textboxes you enter a percentage or an amount depending on the choice on page 1. Because these textboxes and radiobuttons depend on the data present in a database, I have to create them dynamically, so far so good.
The textboxes also have the textchanged event and autopostback, because there needs to be a check if an entered value is valid. Now when I enter a value in a textbox, click on a button that directs me to page 2 (view 2) and select another productgroup, the same value I entered also pops up in the textbox in the same position.
And I don't get it, the table is cleared every time I enter page (view) 3 and the function that creates the table and fills it with data is also correct (with the correct values), but when its displayed the value from the previous productgroup is in the textbox. Is this behavior someone recognizes ? maybe I forgot something simple?

Example: we have different articles in a database like cars, jewelery, boats. The data related to these articles is different in the tables. I have to show that data in a textboxes and let the user change those data and update. I can do the update and reading the data from database. But the problems is for each item the no.of columns and rows will differ.
My task is I need to get the data according to the use selection in the table with textboxes. I dont know which container (gridview, formview or etc) will suites for my requirement. send me any sample code or any tutorial related to this.
Note: showing the data in a table should be a constraint. Because I should show data row wise (each row contains 3 textboxes and 3 labels (DB table column names))

I'm dynamically creating labels and textboxes. The labels are getting the data that they should, but the textboxes aren't. The textboxes are empty if they were newly added or contain data from a previous initialization. There's no difference in the code that I'm using that I can see or think of. What do I need to change to get data to the textboxes?
The following code is in my OnInit event. The code for dynamicTextBoxes is currently commented in favor of dynamicLabelsData, which works as I'd like. myPlaceHolder is a ContentTemplate on the page.

I have a gridview with delete buttons for each record (I've used AccessDataSource). I have loaded the data in and have many duplicate records.
I just want to use the delete button delete each duplicate record while remains many duplicate records. For example:
I used the following query to load in duplicate records:
SELECT * FROM TableA WHERE ([ControlA] IN (SELECT [ControlA] FROM TableA GROUP BY [ControlA] HAVING (COUNT [ControlA]) > 1)))
ID ControlA PIN# FaceValue Date
delete 76637 128232 1234 5 6/4/2006
delete 72722 128232 1234 5 6/4/2006
delete 76638 234567 2345 10 7/3/2006
delete 72723 234567 2345 10 7/3/2006
What is the query to delete single duplicate record instead of deleting all duplicate records?

I have created some dynamic textboxes with standard content.Does anyone know how can I read the content of these textboxes (assuming that user modified the standard content) when I press one button?This is how I am creating the textboxes:
foreach (string name in listOfNames)
{
TextBox tb = new TextBox();
tb.Text = name;
tb.BorderStyle = BorderStyle.None;
tb.BorderWidth = 0;
tb.Font.Name = "Arial";
tb.Font.Size = 8;

I am creating dynamic TextBoxes in a page by clicking a LinkButton.
However, after that, if the page is submitted, I can't find the items created dynamically, thus, can't send the information to the database.
protected void lbAddTag_Click(object sender, EventArgs e)
{
for (int i = 0; i < 3;i++ )
{
CreateTextBox("txtTag-" + i.ToString());
}
}
private void CreateTextBox(string ID)
{
TextBox txt = new TextBox();
txt.ID = ID;
txt.Width = Unit.Pixel(300);
//txt.TextChanged += new EventHandler(OnTextChanged);
txt.AutoPostBack = false;
tagsPanel.Controls.Add(txt);........
in the lbAddTag_Click method I can see the items, and they exist, but if I submit the page and try to insert the values in the database nothing...

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.

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
Repeater.aspx
[Code]....
[Code]....
Repeater.aspx.cs
[Code]....
Right now the problem is im not able to fetch the values of the textboxes present in the newly generated rows.

I'm developing a CMS of sorts, and I want to give my users the possibility of customizing the display. More precisely, I want to give them the ability to choose to display or hide the left column, the right column and/or the top div. The middle column cannot be hidden since this is where the actual content will show, whereas the other columns are for navigation or side menus.
I've been looking for a way to make this as smart and flexible as possible. For now I'm using a MasterPage, but that seems to be too constraining. For instance, with MasterPage you need to add a ContentPlaceHolder control in every of your ASPX pages.
What are the best practices in this area? I guess a simpler way of saying this would be "I want to create a template system over which I have complete control".

I have an (almost) empty aspx page and I want to insert a certain number of the same user control in this page.
I tried to add them from the CodeBehind but it seems that the UserControls are completely empty.
In the main page (MainDiv is a div with runat="server"):
protected void Page_Init(object sender, EventArgs e)
{
WebUserControl1 uc = new WebUserControl1();
WebUserControl1 uc1 = new WebUserControl1();
MainDiv.Controls.Add(uc);
MainDiv.Controls.Add(uc1);
}
(it doesn't work if i put this code on Page_Init, Page_Load or Page_PreRender)
UserControl (gw is a Gridview contained in the UserControl):
protected void Page_PreRender(object sender, EventArgs e)
{
if (_data != null)
{
gw.DataSource = _data;
gw.DataBind();
}
}
when I arrive there, gw is null (this.Controls.Count is 0).
