how to check if a dynamically created control has posted back?The below code is not working.
[Code]....
I have created some imagebuttons dyanmically on page_Init. But the above code always returns null. Why is that? How can I check If an image button has posted back?
Note: I am able to handle the click events of those imagebuttons.
I'm creating a static helper class for web services I'm writing. I'm tapping into the API of Telligent and therefore creating these Telligent "service" objects that allow me to do things with the platform. For example, I'm creating a MembershipSerice object in my helper class so I can do membership stuff with the same object. In my helper class I have a property with a getter that creates a new one of these objects:
private static MembershipService _MembershipService { get return new MembershipService(path, usr, pwd); [code]...
I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.
I have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1 'use a try to target the button, use catch to handle if it's instead a label, only one cell per row. Try Dim accountLink as Button = tblAccountList.Rows(x).Controls(0) Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck Catch ex as InvalidCastException Continue For End Try Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.
I am having an issue with MVC-3 generating outgoing routes for me. This is the address of the page I am on for both scenarios: [URL] Here are the map routes:
[Code]....
Scenario 1: From the controller: [Code].... From the view: [Code]....
The resulting link that gets created. [URL] If I change the controller code to read as follows:
[Code]....
I didn't make any changes in the view, only added those two lines to the controller and the following link is created: [URL] What am I missing here? This is consistent behavior, I was able to reproduce this in other areas of my application.
I have been experiementing with the annonymous types in C#, and am wondering if it would be possible to have a 'dynamic key' in the annonymous object.Here is what I have so far:
[Code]....
[ { "monday": true } ] what I am getting: [ { "temp": true } ]Is there a way to have the object's 'key' be dynamicly created? What I want it to be able to send the KeyValuePair's key as the object's key. Is this possible?
function preview(controlid, clientid) { var radio = document.getElementsByName(clientid); var answer = "k"; for (var ii = 0; ii < radio.length; ii++) { if (radio[ii].checked) answer = radio[ii].value; } PageMethods.SaveAnswer(controlid, answer); }
The problem however is that I want to get the groupname of the radiobuttionlist so I can use getElementsByName, but i have no luck so far.
I'm creating 14 textboxes for every day in a month and user can select the month so i have o create them dynamically. But i can't reach the values in the textboxes.
I have a tree view with checkboxes for leaf nodes. If i click on checkboxes, I am creating some html controls dynamically. And in other static button click event I need to get an ID's of those dynamically created controls.
I will have to retrive data from database assume this is the data I got
|No | Name| 46 ANN 24 LISA 20 JOAN 41 JACK
and so on. I will have to create checkbox dynamical by these data like this
checkbox ANN checkbox LISA checkJOAN checkbox JACK
I will create a container and then create checkbok , then add control to container.. my problem is how to give it a break each 3 controls? and how to format them like this
<TR> <TD width =33%> checkbox ANN </TD> <TD width =33%> checkbox LISA </TD> <TD width =33%> checkbox JOAN </TD> </TR> <TR> <TD width =33%> checkbox JACK </TD> </TD>
In my code behind (c#) I dynamically created some RadioButtonLists with more RadioButtons in each of them. I put all controls to a specific Panel.What I need to know is how to access those controls later as they are not created in .aspx file (with drag and drop from toolbox)?
I tried this:
foreach (Control child in panel.Controls) { Response.Write("test1"); [code]....
"test1" and "test2" dont show up in my page. That means something is wrong with this logic.
I know this question has been asked thousands of times, and I've struggled with it before, but for some reason, I can't accomplish what I want to accomplish... I have a dynamically added LinkButton that when clicked will dynamically add a control (in this example, a textbox) to the same panel. The intent is to continuously add on as many controls as times the LinkButton was clicked (i.e. I click it once, one box, then another click will give me 2 boxes, another click adds a 3rd). In the code below, I use the current date and time serialized to create a unique ID for each textbox control.
When I execute the code, clicking "Add Filter" will generate a new textbox, but once clicked again will create a new one, and dispose of the one before it. Instead, I want to persist the previous textbox as well as any data submitted within it.In the aspx:
I'm creating textboxes in the Page_Load event and giving them values, however whenever I load the details I am getting the same output. I always seem to get the first output I got, even on subsequent searches.Here's what my code with the irrelevant information missing:
If DropDownList has two values (e.g. "Item 1" and "Item 2") and has autopostback enabled, first time it will generate and show "Item 1" in the textbox (the default value for the DropDownList), but if this is changed and the autopostback fires, the textbox does not change.I've tried getting around this by creating a new TextBox, overriding the "LoadPostData" function to prevent this from loading, which got around the issue there, but then I couldn't view the data afterwards.
Any idea how I could get around this? I may be approaching this in the wrong way.Edit: I've added another item to DropDownList that removes TextBox, so that it can be re-created again. It seems to show the correct data when it is re-created after being removed, but if I'm attempting to just edit it, this isn't updating correctly.Edit2: Here's the rest of the code for this page in case this helps at all. The objects which I'm having issues with are SBUName and SBUComments, which are both TextBoxes. The same issue is also happening for SBUClientDropdown but I believe the resolution will be similar:
DBHandler DBHandler = new DBHandler(); List<string> clients = new List<string>(); List<string> clientGroups = new List<string>();
I'm writing a program that inserts controls onto a webform dynamically. Depending on a variable, I add either a textbox, a set of radio buttons, or a set of checkboxes. Later, after a user clicks a submit button I need to use the controls to determine if the user is submitting the correct answer, but when I try to reference the id of a control, I get "txtAnser is not declared. It may be inaccessible due to it's protections level.
