I've been trying to get a grasp around Master Pages.
I haven't done a whole lot of web work in the past few years, and really don't have any need for it in my current professional capacity, but I would still like to understand it.
I have read a few articles and was wondering if anyone could post a simple Master Pages sample for me to digest (preferably in C# or J#).
Nothing over the top, I am just trying (at this point) to understand how the ContentPlaceholders interact with your pages and how and when to use them.
TIA

Just think of the ContentPlaceHolder as a page within a page?
like your including ASP code from another page into your master page whetehr the placeholde is, bit like an include file.
Ill post an example later if i get time. -

Can you not use them to for Controls that require State, for example say a navigation control?

I believe I saw one or two screencasts right here on C9 that deal with master pages... hope it helps.

You should see the master page as a template for the web site. It holds all the page stuff that is on all pages the same. The contentplaceholder holds the content for a certain page.
Example
You have a website with a navigation (on the left) and a header (top). This part is always the same. Right of the navigation you have the content.
You create a new masterpage and put the top (header) and left (navigation/menu) part and a contentplaceholder in the masterpage.
Now you right click on the masterpage file (in Visual Studio) and "Create Content Page". Visual Studio creates a new .aspx file that holds a reference to the master page and the content place holder. There you put the content of the page.
You can access the master page from the code behind, by doing: this.Master.something.
You could for example add a property/method to your master page (let's say the master page is named MyMaster).
You can access that property by using:
string foo = ((MyMaster)this.Master).MyProperty;
((MyMaster)this.Master).SetTitle(...);
That allows you to edit the content of the master page from the content page... -

Excellent, thanks. -
One more thing.
Once I place a Contentholder on a Master page in the IDE, how do I size it and move it around?
When I mouse over some areas, I do get a resizable cursor, indicating I can resize it, but any attempts to do so result in nothing.
Same thing occurs when I try to move it...

Size it? It's not a sizeable thing; it isn't like a panel in Winforms. It'll resize to whatever you want. If you really want sizing or absolute positioning it's time to break out CSS, and wrap the placeholder in a div tag.

ah, I see thanks for the clarification -

You could do some javascript magic here, to have it sizable and movable. You could put the contentplaceholder in a div (in the masterpage) and apply javascript on that div... It's custom code that you would need to develop!

Yeah, I guess my confusion stems from how it appears in the designer. When you drop one on a page, it is freakin huge.
I am figuring I will define my page layout structure as a table in a Master Page and then place my Content PlaceHolders in the appropriatte columns.
That should work, aye?

Yep. Although you should use DIVs instead of TABLEs

Yeah, I know and I'll get there eventually. Like I said, I haven't done any real web work in sometime (before CSS positioning), so for now I will use tables because I know how, later I will refactor to use CSS positioning. -

Just think upon it as the HTML a page spits out instering itself into the content holders on the master page.
So yes, you can certainly use tables or CSS for layouts; but that also explains why it's not a sizeable element; it's not really an element at all, but instructions showing where the HTML will be placed.
