Web Forms :: Unexpected Behavior With Dynamic Textboxes In Multiview Page
Mar 23, 2010
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?
I am developing an ecommerce site that is utilizing PayPal's sandbox environment. I have a login control in the header section of a master page. Everything works as expected until I am redirected back to my site from PayPal. The login control doesn't work as expected. When I click on logout it doesn't change to login or it does change but the user still appears to authenticated.
"To put a node into selection mode, set the node's NavigateUrl property to an empty string."
"When a node is in selection mode, use the SelectAction property to specify which event or events are raised when a node is selected."
"Setting TreeNodeSelectAction value TreeNodeSelectAction.Select Raises the SelectedNodeChanged event when a node is selected."
Here is the problem and possibly a bug in the control:
When I set the TreeNode object PopulateOnDemand value to true and call the Collapse() function on that node.Then the TreeNodeExpanded event is raised in addition to the SelectedNodeChanged event.This is in complate contradiction to what is writen in the MSDN.According to the MSDN this sould happen only if TreeNodeSelectAction Property is set to TreeNodeSelectAction.SelectExpand value.
The first and third view are simple now.The second view contains a user control AgreementDetailUC, which dynamically loads many other user controls onto several dynamically created tabs, as show below
When <Next> and <Previous> button is clicked, it take several seconds to show the second view. Page_Init is run very fast, it seems the time is spent on rendering the page.
My questions are:
1. How can the performance be improved?
2. How to change the cursor to hour glass when a button is clicked and change it back when the new view is shown (I can set it to hour glass when a button is clicked, but don't know how to set it back to normal).
I have a page with an UpdatePanel in wich I load the menu selected Layout pages, and the layouts loads its contents dynamically.
It works fine, but when I load a Layout that has an Multiview control, the code behind of the Layout don't come in into the if(!Page.IsPostBack), ok, I fixed it with if(multiview.ActiveViewIndex==-1) multiview.setactiveview("viewName").
In the Multiview I have a ListView, in the listview I have Linkbuttons that opens another view and shows the information of the specified row dynamically.
when I click in the link so the page disappear from the update panel... why? I do not a full postback of the page, so I think I don't need to reload that page on the update panel... Right?
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.
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.
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.?
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 have a page with 14 dropdown lists. In the first page load (ie. not isPostback) I set the selectedIndex of the dropdownlists individually but I find that they are all set to the value I use for the last dropdownlist set. Here is the code
comboFirstJudge1.SelectedIndex = 0 comboFirstJudge2.SelectedIndex = 0 <so on for all the dropdown lists until the last one> comboFirstJudge14.SelectedIndex = 4
The result is that all dropdown lists have SelectedIndex = 4. If I run the same code on a postback it works just fine (the first lists have SelectedIndex = 0 and the last one = 4).
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.
am using vs.net 2005 with c# i want to create the dynamic textboxes and retrieve the value of them.
i have the following page :
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="testDynamicTextBox.aspx.cs" Inherits="testDynamicTextBox" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server">........
Here when i click on "Add More" button one more text box should be inserted to the form (the maximum limit for textboxes is 10) and when i clicks on the "Submit" button i want to display the content (textvalue) of the text boxes(all the text boxes).
I've been looking for the best method to add "Tab Views" to my .ASPX web pages. I read about one method on the internet and actually remembered the other possible method from a control in the default VS2010 toolkit.
I like the <asp:MultiView> control because its so easy to use. The only thing is that it requires the page to be posted back. The second method would use CSS + JavaScript to essentially emulate tabbed views in the same webpage by changing the styles of <div> elements based upon the users tab selection, making the selected tab appear visible and the other tabs appear invisible.
I like the ease of implementation of the <asp:MultiView> but I dislike the fact that it requires the page to be posted back and resent. Also, I haven't even tried this myself yet but Im assuming there is a way to setup the page to make it look like you can select different tabs with a MultiView. Can anyone confirm this?
I like the CSS+JavaScript method of "Tab Views" because no page postback is required but it is a little more work to code. No big deal really though once its done.
In my web app there is a page(page.aspx). this page inclusdes mutiple views using multiviews. I want to pass querystring value (i.e. id) to this page. 3 processes need to be done
1- querystring value pass to sql statement. 2- sql statement result will pass to page. 3- page determine which views to load
Now, I want to ask
1- what page event handler(s) is responsible for these process? 2- Is the whole process influence on performance?
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'm new in ASP.net, i download your code from the below link.URL...I was searching from net to add a new row in client side i go thru this it was OSOME. I have another dought if you add a one link delete option to delete the row in client side.Another thing if we add a template field such as textbox and dropdown list then there no datafield then how we fill the grid from database.
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 need a way to change the ActiveViewIndex of a multiview control based on some query results. Right now I test to see if I have rows returned from my linq query. If so, set a certain view active. If no rows are returned, I would like to set a different view active. I would like to do this on Page_Load if possible.
Right now I get the fatal "Object reference not set to an instance of an object" error on page load with it bombing at line 12. My count is given a value at runtime so that is not the issue. Can anybody tell me why this is and how to get around it. Code is attached.
I also tried this both the pre render and Page_Init event but both yielded the same behavior with the Object reference not set to an instance of an object error. I can do this just fine in an onclick event for a button, but now I need a way to run a test and set the default view when the page loads. Seecode below
protected void Page_Load(object sender, EventArgs e) { eCrystalPSGDBDataContext psgDB = new eCrystalPSGDBDataContext(); int count = (from st in psgDB.studyTbls where st.patientid_i == Convert.ToInt32(Request.QueryString["PatientId"]) && st.studystatusid_i == 1 select st).Count();if (count == 0)else if (count == 0) { StudyInfoMultiView.ActiveViewIndex = 1; } else { StudyInfoMultiView.ActiveViewIndex = 2; } }
