I'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 page with several textboxes, dropdowns, and check boxes on it. When I click my update button and the update happens, at that point all of the textboxes on the page are locked, I cannot click into any of them. The dropdowns and check boxes still work.
I do have an update panel on the page:

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 the following code. i am dynamically generating some textboxes, and i need to retrieve the values of those boxes at the click of a button in order to save to a Database...
i've searched a lot and i've tried several of the fixes proposed, but so far non have worked...or maybe i am doing it wrong...i don't know...

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'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 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.

more than 24 hours of googling up by now but i hv'nt yet found the commendable solution of my problem. Actually what i searching is ihave a bunch of textboxes created dynamically on the basis of no. of rows in a sql table i put in some data in these textboxes and inserting in other table and here comes the actual problem i have to create the dynamic controls on every postbacks otherwise controls does disappear. other thing i can do is recreate the table on insert button click but in that way i am able to insert the data in the table and recreate the controls but this way text in dynamic textboxes does not remain there.

How can I do that?
I have an asp.net dropDownList listing hours and minutes of the day. I want the time chosen to be shown in a texbox. Can this be done without making a postback?
View 4 RepliesI 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...

View 1 RepliesSuppose, 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 "n" <tables></tables> on my page and each <table> has One(1) <asp:CheckBox.. Enable ='true"/> and "x" <asp:TextBox Enabled="false"..>. Each Table looks as follows

Page also has <asp:Button ...Text="Submit"/> whcih actually grabs the data from the textboxes on the page and send it to the databse. Here is the Onclick event of the <asp"button../>

If the exception is thrown , textBoxes are not reset but on postback textboxes appear as disabled (values are not reset)
So here is what happening on postback when exception is thrown
1) Values are not reset (that is what want)
2) Texboxes appear as Disabled (that is what I don't want on exception, REMEMBER I enable textBoxes using client side script)
How can I keep the textboxes enabled = "true"

I have an ASP.Net Application that in some cases will create up to 100 or so dynamic controls that have events being triggered from CodeDom Assembly. The problem is when at an event is fired off I have to Re-Create all those controls on a PostBack. With 10 to 30 controls its not so bad but with 100 it takes approx 3 to 4 seconds before the user can resume filling out the rest of the controls.
View 2 RepliesCan i know that how can i get a dynamic dropdownlist controls's value after postback?
