Open new page outside masterdetailpage

I just new to Xamarin.Form with Prism. I want to load the page in different behavior. The first one I achieve already is in image below.
But I want to do a behavior like below image. Load a new page outside master detail page. How can I do it in prism?

You have figured out how to display the "Hamburger" icon as well as title by doing the following.
NavigationService.NavigateAsync("MasterPage/NavigationPage/DetailsPage")
If a user makes a selection from the actions listed on the master page. For Example, let's say settings.
You have a couple of options here, you can do navigate relatively
NavigationService.NavigateAsync("Settings")
This will navigate to the settings page. This will also display the back button as the second image. Your current page path will be
MasterPage/NavigationPage/DetailsPage/Settings
Now let's say you want the settings page to be the top details page. You have to navigate to it via an absolute path.
MasterPage/NavigationPage/Settings
NavigationService.NavigateAsync("MasterPage/NavigationPage/Settings")

You need to add a new page to the stack, page over existing one. To do that you should do navigation like this:
navigationService.NavigateAsync("Settings")

How to dynamically add a button using html table in asp.net

I want to add dynamically button in html table.
I created a master page and another subpage.
On the sub page, I want to dynamically add a button in html table.
This is my code:
Button btnSend = new Button();
btnSend.ID = "btnSend";
btnSend.Text = "Send";
btnSend.Click += new System.EventHandler(btnSend_Click);
this.form1.Controls.Add(btnSend);
But I get an error:
form1 is not accessible from sub page.
Please help me to dynamically add a button into the html table.

If you use asp.net then you have no forms. So simply insert a button from the toolbox and set buttonName.visible = true or false as you need.

If you want to add dynamic controls to your sub page, then i suggest you to add a panel, and then simply use panel.controls.add(your button) and thats all.

Do you create the HTML table on codebehind? If so, you may add the button there.
If not, you may try putting a Literal there, and fill it with the code for an HTML button if needed.

Add html text to webcontrol Button in ASP codebehind file

So I am looking for a way to add HTML text to a programmatically created button, or some other control that would accept HTML text and have a on_click_event to capture.
I have a table that I am building dynamically in the codebehind file based upon steps (attendance to a lesson, and the taking of a quiz) that are recorded as complete or incomplete in the database. If a step was not done, I entered a button with a simple X
If the step was done, I just added HTML month and day to the cell.
Attendance to the lesson is a step that can be repeated, so I wanted to make the lesson button look like the styling of a completed quiz, but still capture a 2nd+ attendance point with a click_event.
I am stumped in making a dynamically created button work with my HTML styling. My text style on an ASP.net webcontrol button in a codebehind file is being interpreted as literal text on that button.
Here is the code that fills the cells, either creates the buttons, or adds the text
if(lesson_completed == true)
{
DateTime date = Convert.ToDateTime(lesson);
Button markNewDateComplete = new Button();//System.Web.UI.WebControls.Button Class
markNewDateComplete.Text = "<font style='font-size:50%;color:silver;'>" + date.ToString("MMMM") + "</font><br><font style='color:light gray'>" + date.ToString("dd") + "<font>";
markNewDateComplete.CssClass = "mybtn";
markNewDateComplete.CommandName = lesson_detail_id.ToString();
markNewDateComplete.Click += new EventHandler(this.NewDateLesson_Click);
tc2x.Controls.Add(markNewDateComplete);
}
else
{
DateTime date = Convert.ToDateTime(quiz);
tc2x.Text = "<font style='font-size:50%;color:silver;'>" + date.ToString("MMMM") + "</font><br><font style='color:light gray'>" + date.ToString("dd") + "<font>";
}
Here is what the output looks like on-screen
There are many pages in SO that give insight how to do this in the regular ASPX page, but none that I could find to do this programmatically in a ASPX.cs codebehind file.
In programming there is always another way to do something; so I am looking for a way to add HTML text to a programmatically created button, or some other small control that would accept HTML text and have a on_click_event that I could use as a method back to SQL.
Example of what I want, but this is not for the codebehind file.Font awesome inside asp button

how to hide the master page content in a web page

I want to open a regular .aspx page in a rad window.But the regular page consists of Site Map.I don't want that sitemap to be displayed when it is opened in rad window.
Please suggest me some solution.
I already tried this:
this.MasterpageFile="..//test.Master";
But in my page it does not work

So you will have ContentPlaceHolders which will automatically inherit from the master page. If you go to the regular .aspx page and head into Design view you will see sections with all the content from the Master Page.
If you click the little right arrow to the right of the area that looks like a Div, you should be able to change the content back to what you have in your regular aspx page.

Make a public property on MasterPage to show hide your site map , on your rad window page access that Property and make it hide.
public bool MyProperty()
{
// get and set your controls visibility
}
Access your property like this.Master.MyProperty = false

Best control to handle changin images and text in a asp.net button click

I'm working on a asp.net website.. and I need a little help.. please see image as reference...
What I want to happen is when a button is click from the buttons on the right.. text would appear on the boxed space... I don't know which is the best control to use to hold the text on the space I would like text to appear..
which is the best control to hold images and texts at the same time? and how could I connect it to the button on the right?

You could use the HtmlGenericControl class. It has a constructor which accepts a string variable which initializes a new instance of the HtmlGenericControl class with the specified tag:
var div = new HtmlGenericControl("div");
It is also has InnerHtml and InnerText properties.
Setting up a div with the custom content means you could host images, text or basically anything else that you want to stuff inside a div.
