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

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

I am using VS 2005.I have 5 tables depending on their values ,I need to draw a bar chart.
View 1 RepliesI'm creating multiple textboxes dynamically bases on different criterias, after that every time any control is posting back to the server,
i need to regenerate all the dynamic fields.
What should i do to make the controls stay once added to the form even if a post back occurs.
I have an xml feed that contains a list of form fields that I need to create and then submit to the server once a user has filled it out. Below is a snippet of the xml I am working with. how I should go about creating these controls and retrieving their values on postback?

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..................
I have html table with edit button in asp.net application, when user clicks on edit buttonthe content in td(table cells) will be edited in dynamically created html text boxes with save and cancel button when save button is clicked the data is updated using web method defined in code behind,but how to avoid entering malicious scripts like script tags and otherhtml content into this dynamically generated textboxes to avoid xss attacks.
View 1 RepliesIn 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.
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))
add the numeric values in two textboxes(textbox1+textbox2)
and when the button event takes place
the value(textbox1+textbox2) has to be displayed in textbox3.
can some in send me the code'for that .
i tried to convert string to int
but its trowing some kind of errror
I have a panel (ID=Panel1) holding a user control (ID=QuizMC)
This in turn holds a Label, Textbox and Submit button.
How do I retrieve the value entered into the textbox after postback?
P.S. I'd like a link to a resource which covers this subject (dynamically generated controls etc...).
Is it possible to add values in textboxes as well as subtract values? Scenario:
txtbox1 value = 3
txtbox2 value = 2
txtbox3 value = txtbox - txtbox2
I have able to generate several labels and textboxes based on a table in the database during runtime. My problem is that I could not get these values from these textboxes whenever a user changes these values and update them.
View 4 RepliesI am using this code which works perfect when I type username and the studentid in my textboxes in the first page.Now after pressing the button to go to the second page , the two labels display the values of the textboxes in the first page BUT when I am pressing a button in my second page I get this error :
Object reference not set to an instance of an object.
My code which is in the second page load event is :
Label1.Text = "Name:" + CType(PreviousPage.FindControl("txtusername"), TextBox).Text
Label2.Text = "Student ID:" + CType(PreviousPage.FindControl("txtstudentid"), TextBox).Text
Is there any option to make this labels keep their values ??
I have some textboxes and radio buttons in my form, and when the user clicks the "Search" button, an SQL select query is run from an SQLDataSource and that query populates a gridview. I want some of the values in these textboxes/radiobuttons to act as search criteria and I'll form a WHERE clause based on what the user typed into them. How do I do this?
View 8 RepliesI have a textbox and the date needs to be in between two dates. I want a popup message to display when they are out of those parameters. I don't want to use the Validator's because they make you put in a date to move forward.
One option is if I do use them is it anyway to add "out of date parameters" when they don't meet those dates then move to the next question?
Another option would be to just check the date, give an error message and move to the next question. Is it possible to do either one of these?
I create textboxes in codebehind based on user choice from a dropdown. The user then fills in thevalues of those textboxes and clicks a linkbutton to save the values. When I try to access those textbox values, they are null.
aspx code: <asp:PlaceHolder runat="server" id="TextBoxesHere" />
VB Code:
Private Sub CreateTextBoxes()
Dim ct As Integer = ddlAYIntervals.SelectedValue
TextBoxesHere.Controls.Add(New LiteralControl("<br><table id=""NewIntervals""><tr><th>Interval Name</th><th>Start Date</th><th>End Date</th></tr>"))
' now, create n TextBoxes, adding them to the PlaceHolder TextBoxesHere.........
See I want the values from my database to be displayed in textboxes by stored procedure.
I am having knowledge of inserting values to database by using stored procedure.
For Ex: database fields are
1) Studentid
2) Student name
From user i am accepting Student id in 1st textbox.
when user click ok on the button then he would be having
Student name in next textbox by using Stored Procedure..
Language I am using is C# & internal sql database
I have a form where one field needs to check if the person is up to 17 years of age by between 01/01/2011 and 12/31/2011.
So I added a a Range Validator and Validator Callout Extender
How can I get the page to check this range when the user enters in their dob in the dob textbox then when they go and enter a date in the bmidte box (if they are over 17 years of age) I want my error message to apper.
Here's the aspx page code:
RangeValidatorBMIDte.MinimumValue = "01/01/2011"
RangeValidatorBMIDte.MaximumValue = "12/31/2011"
RangeValidatorBMIDte.ErrorMessage = "Date Entered is NOT Valid. Value needs to be between 01/01/2011 and 12/31/2011."
12/31.
