I have a search page that a user can use to search for certain information about a device (ex. computer) that has been entered into a SQL database. They can search for Brand, Type, Hard Drive Capacity and other things. Once they click the search button, results are displayed in a repeater control. The DeviceID for each device is clickable and when clicked, it takes the user to another page that has all the details about that certain device. I want to be able to display the image for that certain device on that page, as well as all the other information. I have the image being saved as Image type in my SQL database. But I can't figure out how to get it out of my database and display it on the page. I've tried a few different approaches including displaying it in a grid control, which didn't work. I also tried using ASHX files but couldn't quite figure that one out either. I am using C# and ASP.NET. Any help would be greatly appreciated. If any code is needed, please let me know and I will be glad to post it. Thanks!
First hit on Google:
Retrieve Images from a SQL database for display in an Asp.Net Datagrid
Was able to solve this kind of issue using a Handler (ASHX). there are a lot of samples online. try this .. http://www.aspdotnetcodes.com/Insert_Images_Database.aspx

I'm trying to create a project which is basically a library management system.
As a display I used the standard DataSource to WinForm drag and drop system, which displays everything shown in the SQL table.
I want the users to be able to see the content of each row in the grid by double clicking it, which would redirect to another page with the selected row number and information to be displayed on each field.
As for the admin side, I want to be able to modify my db (delete, insert).
Is this the right path, or should I draw a grid from scratch?
Also, my SQL table contains images, this is what's bugging me.
The default gridview shows the little red X's in the varbinary column, and I can't seem to get rid of that.
Regarding inserting data into the table, is there any way to add images directly from the system above? Or should I redirect to a new page and code the respective into textboxes and things of the sort?
Thank you in advance.
the first pictures shows that the address is saved on my database. the 2nd shows my declaration of "product_image" on my database. the 3rd is the how i print the image on my gridview. and the 4th is the result. there is no image of the picture that i called. help me please. thanks. :)
The problem is, Here you are storing Physical path into database that's why it is creating problem, when you are providing full path like C:\user\xx\xx the asp.net application is not able to find those Images,Also this will create problem when you will deploy your application on production.The solution is to store Relative path based on current directory into database.

I'm trying to use Jmeter to simulate adding values, into a database from an ASP.NET website.
I have used the guide found here: https://www.youtube.com/watch?v=zYAiBwJK1v8
To setup the test, and to record the scenario. All of that seems to be working fine. The recorder, records the login to the site, and everything that comes after, including when I push the submit button to add the value to my database. When i afterwards run the recorded scenario it runs with no errors. But nothing is submittet to the database.
The scenario is this: I login to my site, (i'm using browser session id to differ between users)
Now I search for an item, the search text is parsed along with the url (this i can also confirm in the recording, in Jmeter)
Then i add this item to a tabel row in my databse using a submit button. (this also seems to be working in the recording details in Jmeter)
But nothing is added to the database when i use Jmeter to re-run the scenario. Can any one help me to find out, why or what I am missing?
I'm not sure what more information to give, but if you need more information let me know and thank you in advance
First of all I'd recommend checking that your Log In is successful using View Results Tree listener. At top left corner of the listener there will be a drop-down which defaults to Text. Select HTML (download resources) to see full response from server and verify if you're really logged in.
If not, refer to ASP.NET Login Testing with JMeter guide which highlights the peculiarities of simulating ASP.NET application log in including VIEWSTATE and EVENTVALIDATION dynamic form parameters extraction.
Hi I am designing a report using Crystal Report in VS 2010 C# to show students details.
I have designed the Crystal Report like below.
and my actual database table data is
but I am getting output is
What will be the problem?
Ashok as per your question information there might not be any error in your coding but might have error in Cristal report or Application setting.
Check your both that applications and try again.
It’s not quite clear what the issue you have at the moment. But based on your comments there are few areas that I think can be gone wrong.
Check you have correct data source set up (Right click on student under Database fields and go to set data source location and check you are connected to correct database and table)
Also go to file and check whether you have save data with report option is selected. If it is unselect that option
Try go to database and do verify database
Reason behind you seeing values like ###### is definitely because of not enough space been allocated
Hope this helps
You see the "######" because the field itself is not big enough to display the data. There are two ways you can solve this:
Click on the field to highlight it. Then move the mouse along the frame until the cursor changes to an arrow that points left and right ( <-->). Click and hold the left mouse button and resize the field (just like you would resize a window).
You can right-click on the field, select Format Field, and under the common tab you can check the "Can Grow" option.
Ok so here is what am thinking. Am making a recruitment website to hire people. It gives a functionality to the applicant that he can build his cv online! i have made various forms for that.
After filling the forms the applicant will submit the information to database and then am saving all of the information from the webpages related to building cv in the database!
Am thinking of providing the applicant a tab on which when he clicks "View CV" and i show him the cv he built on a new web page in the format like this
http://careers.telenor.com.pk/Page/Detail/VacancyView.aspx?PositionID=3003265
Like the fields should be on the left as table columns and their respective content in the database on the right! Can anybody completely guide me how i can do that ?? or direct me to a specific tutorial ?? i would be grateful! Am using Asp.net!
I have seen grid view! Much like a table it is! with columns on the top and below the values in the database! That is not the thing i want!
DetailsView control can be used to display fields from a single data record. It has that "format" you are looking for.
