View 5 RepliesI have a aspx content page which is associated with a master page. In the code behind of the master page there have code to populate menu control. Besides the menu there is an AJAX Accordion cotrol which is also binding. In the master page there have n number of javascripts written which are being used in master page and also in the content pages.
In the content page n numbers of functionalities are there. Some times I noticed that the textboxes of the content page is getting disabled randomly. Suppose I have perfomed a task in the page and after that I have seen that the textboxes are disabled but later I have performed the same task and it didn't happen, means the problem is arising randomly.
Onething I want to mention here whenever I am mouse clciking on the textboxes when the textboxes are disabled, nothing happens. Neither the any text being selected nor the mouse pointer is showing (textbox doesn't get focus) but after mouse clicking on one of the textbox if I try to type something the letters are coming in the text box without the letter which I first typed and in the meantime all the textboxes are getting enable again.
I'm pulling back an image that is stored in a column in a SQL server database.I need to serve this up on an aspx page.
View 4 RepliesI am trying since more than 5 days to retrieve and display an image in a web page, no success so far.1. I have a table named image, with three fields ImageID, Img_data, Img_contenttype .2. I am able to display the ImageID as a link in my page.3. On clicking the link i am going to my viewImage.aspx?img=ImageID .This far it works ok. ImageID is passing in the query string.4. In this page imageID is being captured from query string and stored in ImageIdview int variable. viewImage.aspx has an image tag to display the image as below.
<asp:Image
id="image1"
ImageUrl='<%# "ViewImageHandler.ashx?imgid=" + Eval("ImageIdview")

View 3 RepliesI'll be debugging a site in Visual Studio 2010 and editing an *.aspx or *.ascx file, and without warning, it will lock up so that I can't edit it. There's no message or anything, I just can't type or make any changes. The only way to start editing again is to stop debugging, close the editing window, and then find whatever file I was working on and reopen it. It's a huge pain in the you-know-what. My colleagues are experiencing the same thing, so it's apparently not something with my particular setup. What's the explanation, and how can we make it stop?
Note 1: I've reported this to Microsoft here. If you've experienced this as well, please go there and vote up the bug report.
Note 2: This is not VSS-related, at least in my case. We use VisualSVN, which doesn't use file-system-level locking to mark files as checked out.

View 7 RepliesI've been having some production runtime errors that I don't fully understand. This has happened to us on a couple different ASP.NET 4.0 Web Sites (shudders - yes, I know - we're porting it to MVC but that's taking some time).
First of all, we have never been able to reproduce this issue in development/QA environments. Secondly, upon deployment, the issue seems to be non-existent. Sometimes the issue manifests within a day or two of deployment and other times the deployment will be live for a month without it manifesting at all. However, once it manifests, then ANY page viewed under the web site causes the error. Lastly, this problem seemed to only come up once we migrated to .NET 4.0. We started at 2.0, a year ago upped to 3.5, and recently upped to 4.0 with this solution and most child projects.
The error:
Could not find the sitemap node with URL '~/Default.aspx'.
A simplified version of our sitemap (with some names changed and uninteresting nodes removed) is as follows:
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0">
<siteMapNode roles="*" title="EG">
<siteMapNode url="~/../SM/Default.aspx" title="Welcome" description="" roles="*" />
<siteMapNode url="~/../SD/Default.aspx" title="SD" description="" roles="*" />
<siteMapNode url="~/../SMD/Default.aspx" title="SMD" description="" roles="*" />
[code]...
I have confirmed in all of the SiteMaps that there is a node with url="~/Default.aspx" with roles="*" (which includes public/anonymous access), so I am very confused as to why this problem occurs.
SiteMap does not have a node for Default.aspx. All of them do. SiteMap's Default.aspx node is not accessible for security reasons to the current user/role. They're all accessible to anonymous users and this problem even exists for super admin users. Passed-in URL contains querystrings (Default.aspx?abcd). I don't know if this is a problem (I sure would hope not) but once the problem manifests itself, I can handwrite the URL with no querystrings and the problem still exists.
SiteMap changes. It doesn't Service's permissions to the sitemap file. The sitemap works perfectly fine after a deployment, so unless permissions are changed in a way that IISRESET fixes, then this is not an issue. The worker process becomes globally corrupt. I don't think so. We have ~12 web sites all in the same app pool and the problem always stays confined within a single web site. Also, we have yet to have this happen to more than a single web site at a time although it has manifested itself in 4 different ones so far.
how do i create linq query and asign that query to as data source to datalist on default.aspx.cs page
View 3 RepliesI've always depended on putting a control on an aspx page and double-clicking in design view to create my VB page. But this isn't happening in my current project. It creates an inline script in my aspx page instead. Where is the option or preference or XML file or.... that controls this?
View 5 RepliesI am unsure on how to perform this task, what i need to do is make a gallery with tagging. I need this as it is a requirement for the project. Each user will have there own gallery and be able to upload and delete images from there gallery. I already know how to insert and select images from a database. I will then display the gallery using a data repeator with paging, I am sure i can google an article for data repeator with paging.
My challenge is, when the user wants to save a image to there gallery, he must 1st upload the image and then i must some how display the image, when the image is displayed, i will have a text box where they can add tags, this textbox will save in the tag table for that user_id, picture_id and the tag will have an id also. I am unsure on how to do this When he clicks save, i wanna insert the image into the table, and the tag. If he does not click save, then nothing should be saved. Now the 2nd part.
In the data repeator, i want a modal window to popup when they click an image, this modal will have the image and the respective tags that where saved for this image, I am unsure how to this.
I want delete, edit, select items is in grid view i have to do in c# code it will reflect to database also

Is ther a way I can tie DataSource to SqlDataSource on aspx page and pass select parameters?
I am generating an aspx page which then I need to convert to png and store it somewhere. A similiar situation with mine was asked before here but got still no response. I tried also the code that the Swapnil Fegade has asked but the code is looping continually making request to loading page and no conversion is actually being done.I found some solutions on the web also but they require WebBrowser control which i understood can be used in windows form but i am building a web project.

View 3 RepliesI am developing on my local machine, therefore my url is http://localhost/<VirtualDirectory>/ My site is hosted at http://www.<DomainName>.com
For example: my link to css file is <link href="/styles/styles.css" rel="stylesheet" type="text/css" />
This works fine on on the public site, but breaks on the dev machine because of the addition of the virtual directory level.
I want to add a key to my config file to manage the current location of the site: <add key="CurrentServerLocation" value="http://localhost/<VirtualDirectory>/"/> or
<add key="CurrentServerLocation" value="http://www.<DomainName>.com"/>
Then I want to add the key value to my links, so that I can change the server path in just one location, config file.
For example:
<link href="<#CurrentServerLocation>/styles/styles.css" rel="stylesheet" type="text/css" />
However, I don't know the correct syntax to add a key value to an aspx page?
I want to achive on functionallity like below.
I want to Dispaly image after image selection.so Users can see image at that moment.
I have two files. The first file is called FinalImage.aspx and here is the code for that page:
<html>
<body>
<img src="newpage.aspx" />
</body>
</html>
newpage.aspx has the following code, based on Jason's sample in the comments below:
<%@ Page Language="C#" %>
<script runat="server" language="c#">
protected void Page_Load(object sender, EventArgs e)
{
Response.ContentType = "image/png";
byte[] data = System.IO.File.ReadAllBytes("http://mystatus.skype.com/smallclassic/eric-greenberg");
Response.OutputStream.Write(data, 0, data.Length);
Response.OutputStream.Flush();
Response.End();
}
</script>
If I call FinalImage.aspx I see a broken image.
If I call newpage.aspx directly, I get a "URI Formats are not supported error"
I think its close, though. this solution is needed to get around the fact that skype does not have an https option for its skype buttons which tell the status of the skype user. Creating this proxy page will allow this to work without causing a 'mixed' security alert in the browser.
I want to display images, which i stored in the MSSQL 2008 with the type of varbinary, in a gridview.
