let say you have table name 'tblData'.
Now if you want to add table row then create table row by
TableRow tr = new TableRow();
Create table cell and add it to table row
TableCell tbcell = new TableCell();
tr.Controls.Add(tbcell);
Then add it to your table
tblData.Controls.Add(tr);

Thanks also from me!
I was wondering about that the other day, but then got distracted.
You have reminded me and solved it in one go

Of course it is, you're telling it to.
<script type="text/javascript"> jungJava(); </script>
This is going to run every time the page loads. Then your script submits the form which causes it to reload, which causes the script run, which submits the form, which cause to reload, which causes...see how it goes?
If you want to happen once then trigger it with an event, such a button click.
Also, notice how the code snippet here is formatted? Use it next time

Hi folks
I'm building this registration system in my asp application and I've got a question. I'd be happy if you provide me with an answer.
I have a code block to check if the entered email exists or not. I've used executeScalar method here. so when the email exists I receive a ONE. now I made an if block telling the machine to print an error then and stop the process. because I'm putting the main process (saving user to DB) after this checkpoint, HOW can I stop the code blocking from process(going on to insertation) if email exists before?
I mean I want the transaction to stop if email exists and this requires I think something like break; or ... . can you help me?

I think this validation is better to do on DB.
But, instead
break use
return

1. Better is to use ID of the selected option which is selected answer of one question.
2. If question is multi-choice then use CheckListBox otherwise use RadioListBox.
Take and look Visual CertExam, you will get idea how will looks and works your application.

Hi,
I have search facility on my web site. I am using .NET framework 3.5 with ASP.NET C# and I would like to display an image on the page. The image i am retrieving is directly from a web site e.g http://somewebsite.com/images/image1.jpg
I am trying to use the <asp:image> control and tried to set the Image URL to the web address but it doesnt work.
I know how to display the image from a web server when using Windows Form by using system.Net and using http requests but i dont know how to go about implementing this in web site.
I would appreciate if somebody could assist me with this?
Thanks,

How are you setting the image? Setting the src property for the image tag is all that is necessary.

I am using <asp:image> control and I am setting the image URL to the web address like this:
String webURL = System.Net.HttpWebRequest.Create(Title.ImageUri.OriginalString).GetResponse().GetResponseStream().ToString()
Image1.ImageURL = webURL;
if i view the source then the src is set to this which is wrong:
img id="ctl00_ContentPlaceHolder1_Image1" src="System.Net.ConnectStream" alt="DVD" style="height:122px;width:122px;border-width:0px;margin-left: 73px" />
Any advice on the above?
Thanks,
|

|

What you are doing is assigning the ImageUrl property the type name, System.Net.ConnectStream, because you are calling ToString() on the Stream object returned from GetResponseStream(). Why did you even think this was necessary or the proper way?
Title.ImageUri.OriginalString is all you need.

Hi,
Yes your right, i only need to specify the OriginalString part. I solved the problem by using the debugger after i replied to your previous message.
When i was developing a Windows Form application I was using HTTpRequests etc and assigning the values to a picture box.
Thanks for the help.

This[^] shows how to insert images to database.

GridView is for display. Manipulating the data and inserting or retrieving from a database is separate.

There are so many examples of how to insert data into a database in books, articles, online, etc. Are you saying you have never seen any example?  If so, then you need more help than we can give you here.

Yes. They can be done using Javascript, HTML !
There are lots of menu's (not exactly the same though, a simpler version) article in CodeProject itself. Search it, try to use the one looks fine to you. You can use, Javascript, jQuery, AJAX based menus to get it. Suit your requirement and knowledge!
