I'm trying to create a calendar extender dynamically on my application. For that i am using the following code:
[Code]....
THe problem is that i'm having a runtime exception, on the OnPreRender of the ExtenderControlBase.cs saying that "A control with ID "filtrodatainicio" could not be found. I'm pretty sure the problem resides in the fact that i'm creating both the text box and the extender dynamically but i can't quite figure out what should i change to make this work.
I'm dynamically adding a calendar extender like so:
[Code]....
When a postback occurs I get the following error:
Extender control 'ceDateFrom' is not a registered extender control.
Extender controls must be registered using RegisterExtenderControl() before calling RegisterScriptDescriptors().
Parameter name: extenderControl
Im trying to dynamically create a popup control extender for labels which are also dynamically created. the labels are one a dynamically created accordion pane. Here is a section of my Page_Init method:
[Code]....
When I run the site with this code I get the following error:Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors.Parameter name: element
I thought it might be because the target control ID changes during compilation so i tried to find the labels in the Page_InitComplete method with this:[Code]....
The expression in the FindControl argument is what the id of the label looks like when i view source in my browser after running the page.I also tried to use the popup control's DynamicControlID property, but im not sure what the DynamicServiceMethod is for.

I am using ASP.NET 2.0 with VB. In design view of grid, i have one textbox in its template field. I also have one Ajax Calender Extender and FilteredTextBox Extender. I have set target controlId of both calender and filteredtextbox extender equal to that textbox. Now dynamically i dispose one of the extender from that textbox. everything works ok. But once my page reloads it takes the original design image, means both extenders are being set to that textbox.

View 2 RepliesI am developing a website that has product images on an external server. I have code that tests to see if the image exists like (pseudo code):
DynamicString = FunctionThatCreatesDynamicString()
' DynamicString = "[URL]
If ImageExists(DyanmicString) = StatusCode.200 Then
' Embed link in ASP.NET page
Else
' Embed not found image in ASP.NET page
End If
My code builds fine and appears to execute. The problem occurs when I attempt to view the external link in a browser, the image appears properly (I have to authenticate first, but that's OK considering I'm on an internal network and this app will be used internally). However, when I attempt the view the source in my generated HTML page, I am seeing the image to the "Not Found" image when I know the image is there. I compared all the characters in my dynamically assembled to the external link and all the characters are matching up correctly. I'm wondering if the authentication has anything to do with why the image is not rendering properly on my rendered HTML.
I'm using a lovely jQuery plugin to load static images into a thumbnail viewer - the locations are hard coded which doesn't serve us any use other than for a demo.
I've managed to pull the images from our server into a unique folder but I've no idea how to load the images dynamically to the plug in. This is the format for the images in the plug in.

The documentation says I can use a JSON array too:
[Code]....
But I don't know how to make this "dynamic". I have the filenames and folder location in C# in my code behind - no idea how to pass this to the jQuery plugin. I can collect the file names and pass to a new ASP page (ie no need to load from the current page).
This is something I just couldn't figure out how to do in ASP.NET:
I have a database of photographs, with upload/management and all that.
What I want to do is to dynamically change/create a css file that changes the background of a div to one of the selected images on the database. (bing.com style).
Is this possible using images stored directly on the database? (sql2008) Or maybe possible only using uploading images to a directory and saving it's path/name on database?
I'm fairly new to ASP.NET but I have developed quite a few WinForms apps in C# where I've used the System.Drawing.Bitmap namespace extensively without much issues.
Today, I decided to write some code to dynamically create some PNGs on the fly in my Page_Load event and everything seems to work fine. But I notice this scary looking warning on the microsoft documentaion site. What is up with that ??
I am unaware of any other ways to deal with images in .Net except using System.Drawing.Bitmap ...

View 2 RepliesI want to create a page that will dynamically change the images displayed, based on which link the user clicked to get there. For example I have different movies listed and when you click a link for one of them it displays all the images for that movie. I need it to be on one page because at the moment I have hundreds of pages and its very hard to manage. I have the images stored in BLOBS on SQL Server 2005. I can retrieve all the images for a certain category and store the Image data for each one into a list of images. What I cant do, is display the images on the page. I can display one image by using the queryString to get the image by ID, then putting the Eval code into an asp:image, but I dont know how to do it for multiple images.
