Does anyone have any idea how I can set a transparency key for an image (Most likely white or, my favourite, Fuschia) - Normal C# has the .MakeTransparent(Color.Fuschia);, yet the ASP.NET Image boxes seem to lack the method...
I have code to pretty much create small images over a large image, which are being loaded from the web, and they're not exactly square, and these random white boxes are... disorienting 
Maybe a way to customise a .jpg to be transparent by default, and THEN upload it... ?
Any help would be GREATLY appreciated!

I believe that later versions of IE support transparency in PNG images.
Also, ASP.NET is constrained by what HTML allows.

Well, it seemed it needed an actual transparency settings.
Paint.NET's transparency function worked wonders 
Thanks anyways

If the control is a CP article, ask in the forum provided by the article. If not, look for a forum where you downloaded the article. Most people here will not have used it, so how can we help ?

Ah - the problem is that you're trying to use a windows control in a web application. You can't do that.

First google hit. You can use a literal to set the header.

Did you read the article ? Once you have a literal, you can change the title in code, anywhere you like.

if one needs to change the value in HTML (as he is asking) one can use javascript and search for the the particular TAG (<title> in this case) ans set its innerTEXT / innerHTML as per requiremnet.
try to use javascript ... it is bit easier solution for your problem without implementing anycode in CODE BEHIND
cheers !

No, you're wrong. Doing stuff in code behind is elegant, allows for object orientation, and works on any browser. Doing stuff in javascript requires that you know for sure that only certain browsers are going to be used, and increases the load on your traffic, because the pages are bigger. It also means you can't comment your code unless you want to also send the comments to the client.
Indeed, because he wants to set his header based on server side events, doing it with javascript would require injecting javascript into the page in the code behind, which would just make this approach doubly retarded.

Hi, I am stuck big time with a problem in Data Grid.
I am using C#, in VS.NET 2003.
I am writing a simple web mail system, and I am using the datagrid to display the inbox.
It is a very standard inbox, nothing fancy, and I am displaying the sender, subject, as well as the date sent. For each message there is an extra column "opened" which denotes whether the message has been read.
Here's what I am stuck, I need to BOLD the message subject for those messages which are unread.
I have absolutely no idea where to place the codes, the pseudocode is very simple, simply:
If the "opened" column for that particular message is NO,
then BOLD the subject
Where do I place the codes? I tried to place it in the HTML code as well as the codebehind, no luck.
Any suggestions??? HELP!!!
Thanks!!!

First suggestion, post your code so we can point out what you're doing wrong.
I would do something like writing a div to contain the text, and then having the style set the font weight via a property that comes from the codebehind, which in turn is passed the opened value, and returns the right string for plain or bold text.

Thanks for the reply.
Here is the code for the part that displays the Template Column.
<br />
<asp:TemplateColumn HeaderText="Subject" ItemStyle-CssClass="content"><br />
<HeaderStyle CssClass="subtitle"></HeaderStyle><br />
<ItemStyle Width="350px"></ItemStyle><br />
<ItemTemplate><br />
<asp:HyperLink id="Viewmessage" runat=server CssClass="content" NavigateUrl='<%#"viewmessage.aspx?messageid=" + DataBinder.Eval(Container.DataItem,"messageid") %>'><br />
<font class="content"><br />
<%# DataBinder.Eval(Container.DataItem,"messagesubject") %><br />
</font><br />
</asp:HyperLink><br />
</ItemTemplate><br />
</asp:TemplateColumn><br />
As you can see, the code above only retreives the SUBJECT and displays it.
Is it possible to put a IF condition in the HTML Code? It is possible to do something like this?
<br />
<asp:TemplateColumn HeaderText="Subject" ItemStyle-CssClass="content"><br />
<HeaderStyle CssClass="subtitle"></HeaderStyle><br />
<ItemStyle Width="350px"></ItemStyle><br />
<ItemTemplate><br />
<asp:HyperLink id="Viewmessage" runat=server CssClass="content" NavigateUrl='<%#"viewmessage.aspx?messageid=" + DataBinder.Eval(Container.DataItem,"messageid") %>'><br />
<br />
<%#<br />
if (DataBinder.Eval(Container.DataItem,"opened") == "no")<br />
{<br />
SET FONT = BOLD<br />
}<br />
%><br />
<br />
<font class="content"><br />
<%# DataBinder.Eval(Container.DataItem,"messagesubject") %><br />
</font><br />
</asp:HyperLink><br />
</ItemTemplate><br />
</asp:TemplateColumn><br />
Thanks!!!

You can do this:
]]>
// add tags for column here
]]>
I may have some details wrong here, but I know I've done a control that added columns to a datagrid in certain modes using code similar to this.

Hi Friends,
I have one Com Dll to hash the password.
How to use that DLL in ASP.net to hash the password.
Thanks
Hari

Import it into your project the same way you would any COM dll and call it in your business layer.
Of course, it makes more sense to use the crypto stuff built into .NET
