newbie: load image from db + Repeater

hey
asp.net 2.0
With the help of a Repeater control on my webpage I want to dynamically
generate a list which contains both images and text field. This data are
stored in the aspnetdb.mdf database.
I know it's possible to have the imag tag to point to a .aspx file (<img
src="getImage.aspx" /> )
This is the Page_Load event I have in my getImage.aspx file
protected void Page_Load(object sender, EventArgs e)
{
if (Profile.Picture != null)
{
Response.ContentType = Profile.PictureType;
Response.BinaryWrite(Profile.Picture);
Response.End();
}
}
The getImage.aspx file above is used another place in my project. My PROBLEM
is that I don't know how to adapt (make another version of getImage.aspx
which suit the repeater) this getImage.aspx file into the Repeater control.
More specific: in the Page_Load event of getImage.aspx you see that I'm
setting some properties of the Response object with some values of the
Profile object. But in the new getImage.aspx file (created specially for the
Repeater control) I must for each line in the Repeater control pass over the
correct ID to the Page_Load event so the getImage.aspx file knows what image
to load!
In other words how can I tell the Page_Load event what image to show. I
think about using a paramter. But my problem is that I don't know how to add
such a parameter. Maybe it could be passed in the EventArgs argument.. I'm
not sure...
Instead of sending the picture ID I could send over the bytes representing
the image. But even that, I (As Far As I Know) still have to send a paramter
to the Page_Load event
Any ideas how I should pass over such a parameter?
Jeffhello Jeff
you can track the id's and do something like getImage ( id ) in the
ItemDataBound event.
on this page is a similar example, though uses a GridView instead, but
logically it's the same

NEWBIE: passing error to javascript alert

Hello,
is there a way call a javascript function directly from within asp
page?
Example, here is page load event in C#

protected void Page_Load(object sender, EventArgs e){

// create error
int Var0 = 0;
try {
int iVar1 = 8/Var0;
}

catch (Exception ex){

string sExMsg = ex.Message;

//javascript works fine with string constant
Response.Write("<script type='text/javascript'>alert('In Catch');</
script>");

//can write error to page no problem
Response.Write(sExMsg);

// would like a popup with error
Response.Write("<script language='javascript'>doAlert(" + sExMsg +
");</script>");
Response.Write("<script language='javascript'>function doAlert(sExMsg)
{alert(sExMsg);}</script>");

//write error to log since I can't pop-it-up
//StreamWriter sw = File.AppendText(Server.MapPath("~/error.log"));
//sw.WriteLine(sExMsg);
//sw.Close();

}

}

Any help for a newbie is appreciated

Wherever you like, so long as you don't Redirect from the page...

Basically, it will send down the JavaScript to run after the page had
loaded...

Yes.

Incidentally, why are you actually doing this...?

basically for debugging. I don't like response.writes and I'm trying
to learn javascript. but if you know of a better way to popup alerts,
let me know.
use the debugger to debug. alert debugging is asp classic style :)

Not much use in this particular case, though, as the OP's requirements for
this were for debugging a la ASP Classic...

Try to rebuild the project and re-load the page in the browser. You might be
having this error as the page class the newly added page inherits from in
its @.Page directive has not been compiled into the code-behind assembly.
