I would suggest doing something like using Javascript to obtain the client width of the browser, then resizing the image accordingly based on this. For example, you could make the image width 50% of the browser client width, then using this, you could change the image height to make it in proportion with the width.

I can give you a code example if you want it.

Hope this helps,

Dynamically loading SQL data(ASP.NET, C#)

Hi, i am making a webpage with asp and C# and now I have a couple of buttons with a table below. Now when the user click a button it loads the appropriate data from sql and puts it in the table. But how can i make this happen without the page refreshing? I have put the code in the OnClick of the button but the page still refreshes(which takes a while because it also reloads the images - which is why i want to do it without refreshing). I have seen this being done on phpBB forums when you quick reply.
Please help me.
Thanks Big Grin | :-D

So its because its causing a postback? Are there any other controls that dont cause postback's that i can use instead?

Anand Desai1-Aug-08 1:11

Debug your code. You will find its doing "PostBack" each time.

You must use Ajax to resolve it

Sorry for being ignorant and wasting your time, but I have never use AJAX. Wouldnt i have to install something on the server for that? I have no access to the server except htdocs folder.
Also how would I do this with ajax? Can i run a C# method(like an onlclick function) that would do it?

Thanks Smile | :)

where emp.name = '" + stringname + "'"

ok, ur misunderstanding. Heres code from something i did a while back. just adapt it to your needs.

sqlConn.Open();
SqlCommand cmdShowCat = sqlConn.CreateCommand();
cmdShowCat.CommandText = "SELECT * From Type WHERE TypeName LIKE '[R]%'";
SqlDataReader readerShowCat = cmdShowCat.ExecuteReader();

while(readerShowCat.Read())
{
string TypeName = (string)readerShowCat["TypeName"];
catagoriesLabel.Text = catagoriesLabel.Text + "
" + TypeName;
}
if (catagoriesLabel.Text == "") { catagoriesLabel.Text = "Sorry, there were no results."; }

sqlConn.Close();

hello frndz,
I am very confused, which transaction level should i use ???
What i want to do is , I have to insert 1000 value in a database table n i used transaction handling concept for that purpose.
My Isolation level is "READ COMMITED" but if any other user try to insert record in same table then it will retun me TIME OUT exception.

i think it will lock whole table till i completed my transaction...

what can i do for it ???

can i lock that perticular rows which i inserted???

any other hint ??? that table should not get locked ???

I have Sqlserver 2000 and .NET 2.0

thanks in advance

iframe is taking spaces also while loading the text in the hidden field

1-Aug-08 1:06

Use Stored procedure instead of single transactions..

it lockes the SQL from its process Begin...to....End.

Re: display problem with tables

Hi
I am using tables to do the outline design for my webpage.
The problem is, is that there is small gaps between each tables which I want to remove so that all areas are tight to each other.
Is there a way to do this, like reduce padding on table or border?

thanks Smile | :)
