How can i develop a product catalog that diplay a large picture of product and put the description with price under the picture? I use DataList, but the pictures don't appear. Is it true, if i use image handler, my data type for image must be in binary? My current data type for image now is varchar.
<asp:DataList
id="dlstImages"
RepeatColumns="3"
runat="server">
<ItemTemplate>
<asp:Image ID="Image1"
ImageUrl='<%# Eval("Name", "~/UploadImages/{0}") %>'
style="width:200px"
Runat="server" />
<br />
<%# Eval("Name") %>
</ItemTemplate>
</asp:DataList>

Varchar will screw up the data, I would guess. You should definitely use binary fields.
However, what you are doing here appears to be linking to an image on the server, not the image in the database; this means that the image name would be in varchar. Is your intention to refer to a folder, or to display the image data directly?
Also, you might want to use <img> tags instead of <asp:Image> controls; most people would consider it better practice to use the simplest control possible unless there's a good reason not to.

I use datatype varchar for image (put image path) and display in gridview, this is fine. But when i use the same datatype and display in datalist, the image didn't appear, but the description and price for the product appear. If i use binary for image, then i need to upload the picture to DB, rite? and also use generic handler. what is the easier way to display image for product and the details from different product categories (it's like e-commerce application)?

Displaying binary data directly in ASP is a bit hairy. I'd stick with an <img tag; View Source in IE to see what the path is, and check the data list to see if it's formatting your HTML as text - there should be a property in there somewhere. Again, View Source will help you out. My instinct is that it's some kind of HTML formatting issue.

LOL.
You want to catch a click event on datagrid one, and then use a value selected from that row, to select the data to show in grid two.

Hi,
I have a Td, which Iam converting it to edit mode.And Iam giving a textarea by which User can type along with the Old string in td.
But the problem is the textarea is not getting fixed to the Td.
I have given overflow:auto even set width and height to 100%
however if I press enter button in textarea itz getting fixed to Td.
so I tried using "/r/n" which is next line still the problem persists..
Can any one tell me how to INSERT A ENTER to the end of a String in Javascript? or is there any other solutions
Thanks in Advance

I would use a repeater to generate my bullet list, if you are doing it from a data source. Then I'd render links that post back to allow you to create the behaviour you're after

Hi
i need to check the information on a web page and access information to text box on this web, by code.
how can i do that in c#?
thanks.

Is it your web page and you are writing the server side code? If so the server side code is the same as writing a C# application with forms:
string str = textBox1.text;

Thanks Dan
Its a client side. i need to open the site as a regular internet user do, on screen.
check the information on screen and access to txtbox with no human intervention.
how to do that?

You can download the the web page using a httpWebRequest object (I think thats its name - its definitely close).
Parse the web page that is returned for the name of the textbox and then parse its value - that should do it.

Hi there,
Ok.. not really too grate on the C# / Generics bit.. so feel free to laugh!
I have a simple idea.. a stupid implementation!
I am trying to create a generic method to cache something (i.e. string, hashtable, etc), and the a simple method to return that cached generic value without unboxing.
So I have something like:
(Create method)
public void add<T>(string ID, T itemAdd)
{
Cache.Insert(ID, itemAdd);
}
(Retrieve method)
public void ret<T>(string ID, T itemBack)
{
itemBack = Cache.Get(ID);
}
Okay, okay, I know that doesn't look right, and the only way I can get it to work is:
public void ret<T>(string ID, T itemBack)
{
itemBack = (T)Cache.Get(ID);
}
Obviously the way it works is by unboxing the cache item back rather than some "generics" magic.
As I said, I am not an expert, and I have been searching to find references to this albeit not
too successfully as I am probably asking the wrong question!
Any ideas, or laughs at my stupidity most welcome! </t></t></t>

More fun... actualy found that in an ASP.NET page, you can of course do the following with the Cache object:
Cache.Cast<T> which takes the content of the Cache and makes it available to whatever generic type you need.
Also, got around (albeit I'm guessing not necessarily a best practice) the Cache retrieval part within a class using HTTPruntime and the following:
public T getCache<T>(string CacheID)
{
if (CacheID != null)
{
return (T)Cache.Get(CacheID);
}
else
{
return default(T);
}
}
Not pretty.. but works... the only thing now is finding out WHY and if I SHOULD !!!

This is not the right forum for this question. However, I'm in a good mood so I'll answer it - you need to download the VS2005 extensions here[^] assuming you are using VS2005.

hi all, i have made asp.net application in C#. suppose my site adress is
"abc.com"
I have pages related to admin and user but there are no folder, there
are internal page links on my site, like login link, when login link is
clicked within site user is redirected to "abc.com/login.aspx" and this
appear as it is on Ie browser bar, what i want is it should
"abc.com/admin/login.aspx" or "abc.com" (change browser bar adress and use
httpcontext.rewritepath() method),
There more similar situations like this but that is simplest, i know
other solution of that instead of login.aspx, link href should be
"/admin/login.aspx" but i dont want this solution and use
httpcontext.Rewritepath() method.
what i am intrested is href should be "abc.com/login.aspx" but afer
clicking on link and on post back Browser bar should display
"abc.com/admin/login.aspx" or only "abc.com", i want change values from
browser bar.
i hope you understand this problem i am doing this asp.net C#.
Regards.

The autoeventwireup , if it is set to false , it will not execute the code written in the page load function , and reverse is true.
My question is , how should i implement this case in the project and in which situation i should use it?
If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

you have create your own eventhandler
delegte it to execute function. you have also create some custome property , if its true then you should delegete to that function else not.
Pankaj Garg wrote: which situation i should use it?
if you check "FileSystemWatcher" components in C# windows application, it has raised event like "Create, Delete , Rename and Changed" and according to that it delegate to some function.
Now there is a property EnableRaisingEvents . if you set it to yes then it will raised those events.
hope this clears you !!!
