I need to have a button on the master page.
Once that button is clicked I generate a string that represents URL.
test.apx is a content page I use and the string will look like something like this:
Example:
www.blah.com/test.aspx?user=blax&develop=extreme_all
Now all I need is to reload the page while content is redirected to the URL I generated.
I hope this makes more sense.
Thanks guys I am new to asp.net and really appreciate any help
Why dont you use Update Panel?
Have the page postback with the updated query string to change what is in your content area
Assuming your masterpage is set up correctly
within the <asp:content> tag of your aspx page that is using the masterpage you created add code to get the query string
Request.QueryString["key"]
example url: http://www.whatever.com?foo=bar&bar=foo
string tmp = Request.QueryString["foo"]
tmp will become "bar"
Now just check the "postback" option of the asp:control you're using to reload the content page or do whatever you to make the page refresh.
If I understand your question correctly, you want to reuse the same code to parse out your user and develop variables from different content pages that use the same master page.
It sounds like you need a strongly typed master page.
First, put your shared code in your master page. Then, expose the parsed data as properties of the master page. Next, simply add the following directive in your content pages:
<%# MasterType VirtualPath="~/mymasterpage.master" %>
Finally, in your content pages, you can reference your properties as such (assuming you created a property called MyUser):
string user = this.Master.MyUser;
You can also use inheritance if you want a different approach. Simply create class that inherits from Page. Then put your shared code in that class. Finally, make your content pages inherit from your new class, instead of Page.

Assume I have an list or array (doesn't matter) in a aspx.cs page. How can I pass that list/array etc to send it to a master page. Then in a function use that information to pass to an .aspx page without passing the list/array to the function?
Hope this makes sense. Thank you.
My best guess to your answer would be storing the variable in session (Session.MyVariable) and once the child page loads, access it via that way. You wouldn't necessarily be passing it from the layout page to the view but this would allow you to get whatever data to the view once it's loaded under the layout page. If that helps, not entirely sure I understand.
In the "header" of the child page
#{
if (Session.MyVariable != null)
{
// do something on the webpage with this data
}
}

Go to the part where he describes "Changing the Master Page's Properties from Content Pages", he defined a label in site master, then he was able to change the text of this label from the content pages.
My best guest is to pass like a serialized XML and then parse it in master page
I want to assign the html content to iframe control from asp.net code behind page;
this is working fine
myIframe.Attributes.Add("src", "pathtofilewith.html");
but, i don't want to give the path of html file to display i just want to assign some html content which comes from database to iframe control.
i want some thing like this(Ashok) to be displayed in iframe control
i tried the bellow ways but nothing is succesful
myIframe.Attributes["innerHTML"] = "<h1>Thank You..</h1>";
myIframe.Attributes.Add("innerHTML", "<h1>Ashok</h1>");
A way to communicate between two different pages where one is in an IFrame on the other, is to post data using JQuery. An example is given in this StackOverflow question
It is also discussed in this other StackOverflow question
On this page, you will also find a short and simple example of how you can put content in an IFrame without using a separate web-page for it (note the lacking src attribute!).
Hope some of this helps!
You can't. That's not how an IFRAME works - it is for use with the src attribute as you've already discovered.
Perhaps you want to create a DIV instead
There is no way to insert HTML content into iframe tag directly, but you can create a page which gets the content form the database and then you can view it using iframe,
or
You can create a page for example called getContent.aspx which request value from the URL e.g. getContent.aspx?content=<h1>Thank You..</h1> and display it wherever you like, and then call it from iframe.
In ASP.NET, I have a master page, and five other pages which are under master page.
In all five pages, I need to implement a button, after clicking it, will generate different download results.
My original implementation is, in all five page, will all have a "Button", so in code behind will have corresponding event method to generate the download.
But my approach, will have duplicated html compoents.
Is there a way I can define the download button in my master page, when clicking button in different page, event method from different page will be invoked?
Yes you can, on master page you can have a Download Button and on it click check the URL, which will help you to identify the request has come from which page. Then you can write code on the basis of current page being displayed.
You can use the SHTML instead of HTML and include it every where that you need it.
I don't know what exactly You want to achieve, but maybe it would be better to have one aspx with the button and load the correct ascx file to this page according to some criteria? Each ascx can derive from some interface with some method, f.e. Click(), and each time the button on aspx is clicked, the Click() method from currently loaded ascx can be called.
I'm looking for a way to (preferably) strongly type a master page from a user control which is found in a content page that uses the master page.
Sadly, you can't use this in a user control:
<%# MasterType VirtualPath="~/Masters/Whatever.master" %>
I'm trying to access a property of the master page from the user control and would rather not have to pass the property from the master page to the content page to the user control because multiple content pages use the same user control. One change, one place whatnot.
Try Page.Master.
Whatever whatev = (Whatever)Page.Master;
You'll have to make sure you add the proper using statements to the top of your file, or qualify the Master page type inline.
One potential gotcha is if this control is used by a different page whose master page is NOT the same type. This would only get caught at runtime.
Have you tryed Page.FindControl("name") on the usercontrol?
The best way to do it that I've found is actually to build a custom class that is based off of UserControl, give it a Master property with a get accessor that fishes through the this.Page.Parent until it stops encountering master pages (If you are nesting, this step is unnecessary otherwise) and then return that web control as the type of the master page you want to use. Then, when you add a new user control, change it's base class to the name of your custom class. The .Master property will be accessible and cast properly as the master page you want it to use.
In VB all I needed to do was change this:
Dim lAuthLevel As Integer = Master.MasterContact.AuthenticationLevel
to this:
Dim lAuthLevel As Integer = CType(Me.Page.Master, main).MasterContact.AuthenticationLevel
So all references of Master become Ctype(Me.Page.Master, typeofMaster)
Where is in this case the word "main" - get that from the declaration at the top of the master page. e.g.
So "main" in this case :)
From what I've already read this appears to be impossible, but I wanted to see if anyone out there has a secret trick up their sleeve or at least a definitive "no".
Supposedly a master page is really just a control for a content page to use, not actually the "master" of a content page. If I wanted to go from one content page, to another content page with the same master page, I would just say
Response.Redirect("PageB.aspx");
But this would immediately cause a postback, flickering the page, which is the crappy pre-ajax way of doing things.
In this current project, I'm trying to see if I could figure out how to change the current content page of a ContentPlaceHolder in the master page asynchronously, when a button is clicked on the master page.
Is this possible, if so how?
I don't know if you can between pages (.aspx) but it can definitely be done using UserControls.
ASP.Net pages each have their own URL so what you're trying to do is to go from one URL to another without any postback, that's just not how it's supposed to work.
Using user controls (.ascx):
Create a page that uses the MasterPage and use something like this in the content
<ajax:UpdatePanel ...>
<ContentTemplate>
<asp:PlaceHolder ...>
</ContentTemplate>
</ajax:UpdatePanel>
Search for UpdatePanel and tweak its settings to do what you want, then learn how to swap user controls in a placeholder.
No, you cannot because a master page is actually a control rendered on a particular aspx page, rather than actually containing the aspx page as it deceptively appears to be programmatically and in design view.
More Info:
You could however use a variety of other controls to simulate this effect. The asp:MultiView control is one example, each "page" could be made in a single view and placed in an update panel, thus allowing it to be switched asynchronously. Alternatively you could define each page in a separate user control and put those in an update panel, asynchronously switching the visible property on those controls as needed.
There are really a lot of different ways to achieve an effect similar to changing the master page's content placeholder.
