My problem is that I have an ASPX page which contains an ASP:Table. The rows for the table is added dynamically on Page_Load. One column in the table contains TextBoxes, BUT when I type something on a TextBox and cause a postback, I am unable to find the value just entered. And above that the table is not displayed after the postback.Can anyone help me please? I want to keep the table viewstate with the modified textbox values, so that when i post back to server, I can intercept these new values.

I've just setup a new site on my IIS6 and I'm experiencing the following problem:

I have a table thats created dynamically, the table gets its contents from a custom class I've created that gets statistical data from a database. As the table is generated dynamically, I've put the contents class (the table data) into a session object and I populate the table initially inside a !IsPostback then on the page init I get the data from the session (its empty on the firts page load). I am now getting this error: Multiple controls with the same ID 'controlnamehere' were found. FindControl requires that controls have unique IDs. How can I avoid this?

what I am currently doing is creating an aspx form dynamically and saving its data by using Server.Transfer("PrssPage.aspx").
On ProcessPage.aspx I am using the Previous Page property to save the data entered by the user using the dynamically created form.
Each Dynamic Form is provided an ID for example 123.aspx
Now what I want to achieve is to repopulate the dynamically created aspx page with the user input values from database, plz note here that I do not have an aspx.cs page getting dynamically generated. I am only generating aspx page.
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'm working on an ASP.NET project in which the vast majority of the forms are generated dynamically at run time (form definitions are stored in a DB for customizability). Therefore, I have to dynamically create and add my controls to the Page every time OnLoad fires, regardless of IsPostBack. This has been working just fine and .NET takes care of managing ViewState for these controls.
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
RenderDynamicControls()
}
private void RenderDynamicControls(){
//1. call service layer to retrieve form definition
//2. create and add controls to page container
}
I have a new requirement in which if a user clicks on a given button (this button is created at design time) the page should be re-rendered in a slightly different way. So in addition to the code that executes in OnLoad (i.e. RenderDynamicControls()), I have this code:
protected void MyButton_Click(object sender, EventArgs e)
{
RenderDynamicControlsALittleDifferently() [code]
My question is, is this really the only way to accomplish what I'm after? It seems beyond hacky to effectively render the form twice simply to respond to a button click. I gather from my research that this is simply how the page-lifecycle works in ASP.NET: Namely, that OnLoad must fire on every Postback before child events are invoked. Still, it's worthwhile to check with the SO community before having to drink the kool-aid.
On a related note, once I get this feature completed, I'm planning on throwing an UpdatePanel on the page to perform the page updates via Ajax.
i have an array of buttons added to a panel control and need to reset them to their original values, is this possible pragmatically?
protected void Page_Load(object sender, EventArgs e)
{
RenderTable();
}

How can i make the Page event fired from the Selected index changed of the dropdowns keeping the autopostback property to be set as false.
View 5 RepliesHow do i handle 404 page not found?
View 5 RepliesI have a CentOS 5.x server running Mono 2.8.1 and mod_mono 2.8 with apache2.
Every time I deploy a site from visual studio 2010 to my server by ftp, and navigate to the site, I get a 404 not found error page.
Sites in other subdomains (virtual hosts) are not affected.
Performing a restart of httpd using /etc/init.d/httpd restart fixes the problem, and I can view my ASP site again. Obviously restarting the entire httpd process is less than adequate.
My guess is that this is similar to application domains in IIS. Is there a way to 'recycle' and app domain in mod_mono? Can I set this to happen on deployment?
