Thank you. I've been fussing with my code, on and off, for the last few days trying to figure out why I couldn't get my string output of XML data to bind to my ListView object in .Net 3.5. I found the "onPreRender" statement in another article but a separate test datalist object bound fine in the "OnLoad" event. Turning the caching off was exactly what I needed- thanks.

Do you want to host it at home? I would use a hosting company, it costs about $100 - $500 per year to have an asp.net / sql server site hosted for you.
I didn't get any requirements for the signature

i also want to use a hosting company...so for that wat shud i do?? will i need to make any changes in my code or just approach any company with my code and database??

I used http://www.appliedi.net/aspnet-3.5-hosting/[^] and it was pretty easy.
They give you a virtual directory with FTP access to it. You can use any ftp program to copy up your website.
They will give a SQL Server database. You will get owner rights to your own database. You connect to it via the IP address right from Management studio on your desktop computer.
Good luck.

Hi,
After inserting the data I am clearing the textbox and dropdownlist. But when I press the refresh button in the browser once again the data is inserted. This happens not only for Insert but also for all are the event that happens last once again happens when browser refreshed. We are not using Ajax.
Thanks,
Ashok

try by setting the enableviewstate property of the controls to false
|
|
|
|
|
Redirect to the same page using Response.Redirect() once you have successfully enter the data. This will prevent the refreshing in performing a postback.
|
|
|
|
|
One easy way to handle this is to set a session variable the first time the page is posted. You can check for the presence of this on any refresh and if it already exists, prohibit posting of any information.

These lengthy coding is not necessary....You can find GroupName property of each radiobutton. Give the same groupname to all radiobuttons. and try

Good answer, but this is the ASP.NET forum.
However, I have a feeling you're right anyway as I think, looking at the code, that this is a winforms question!
|
|
|
|
|
The questioner asked that cannot be selected the only one radiobutton at a time. I thought that the person used this code as code behind for web form. Thats why I replied like this.

The whole point of a list of radio buttons is that only 1 item is selectable. If you use an asp:RadioButtonList it does all this for you.
Saying that, what exactly doesnt work in the code you've written?

thank u got the point... but i will try it..

Hello,
I'm trying to display a picture from my db using linq.
protected void Button1_Click(object sender, EventArgs e)
{
DataClassesDataContext db = new DataClassesDataContext();
test1 x2 = db.test1s.First(p => p.descriere.StartsWith(" Firma bazata pe intuitia cumparatorulu"));
byte[] img = (x2.img);
MemoryStream ms = new MemoryStream(img);
System.Drawing.Image Image1 = System.Drawing.Image.FromStream(ms);
MemoryStream stream = new MemoryStream;
Image1.Save(stream,ImageFormat.Jpeg);
Bitmap b = new Bitmap(Image1.Width, Image1.Height);
Graphics g = new Graphics.FromImage(b);
}
where test1 is a table with 3 fields- id-int/descriere char/img image.
my error: 'System.Drawing.Graphics.FromImage(System.Drawing.Image)' is a 'method' but is used like a 'type'.
Can someone tell me what why or tell me how to do it? Please dont tell me to search on goole..
i have read everything i could find on google and i cant figure it out.. i'm new in the field.

Hi,
the compiler error is saying anything. First Graphics.FromImage is a static method so you should rewrite it like this:
Graphics g = Graphics.FromImage(b);
Second if you try to run a method on an object, created in the same line you have to write it like this:
object a = (new B()).callMethodA();
Regards
Sebastian

byte[] img = (x2.img);
MemoryStream ms = new MemoryStream(img);
System.Drawing.Image Image1 = System.Drawing.Image.FromStream(ms);
MemoryStream stream = new MemoryStream();
Image1.Save(stream,ImageFormat.Jpeg);
Bitmap b = new Bitmap(Image1.Width, Image1.Height);
Graphics g = Graphics.FromImage(b);
g.DrawImage(Image1, 0, 0);
}
the code works but it doesn't display anything. When i debugged i saw that the image is loaded correctly in image1 and in b. Any ideas?

Do you have a control to display the image? ImageBox or Image?
|
|
|
|
|
Yes, the control is Image1 - type System.Web.UI.WebControls.Image
|
|
|
|
|
The problem is that it is not that simple. The Image Control needs an URL to point to the image to display. What you need to do is to build a page which takes the image-identifier as parameter (within the query string) and puts out as response the image content. The Image Control points to this page. Sounds complicated but is really easy. Found a tutorial in the web:

Hope this helps.

Hi,
I want to use a Frameset in .net webpage. This Framset is to create a Left Navigation menu. In the Frameset i want to have a Tree view control. I dont have idea about the Frameset. Can anybody pls help me on how to use a Frameset in .Net with Tree view control.
Tnx in advance.
With Regards,
Anand

Do not use a frame set!
Try a master page. There are countless examples of how to do this all over the interweb.
