C# WIndows phone disable button after one press

I'm making a Windows Phone 8.1 app in Visual Studio 2013.
I have a page where a user sees an image and button labelled "Complete". The user has to do (in real life) what is in the image, and then press the button. After the button is pressed he is awarded 3 points.
Once the user presses the button, the first time, I would like to disable it. Right now, there is a bug where the user can press it many times and gain more points from one task.

Try doing this:
Button myButton = FindName("ButtonName") as Button;
myButton.IsEnabled = false;

Control default action in ASP on Enter

This may be an easy question for you guys.
I have a web form with several buttons and only one textbox. When I enter a value in the textbox and press enter the method gets executed that is wired to the first top left button. I need to control what button's method gets executed (in this case it is a button in a whole different location that does db query).
I tried to alter tab index to have my desired button the lowest and I tried to pass focus to my desired button on page_load (like I would have done in Win Forms) but still if I enter text in textbox and hit eneter, the top left button's method gets executed.
I could put conditions in execution of top left button's method but that would be a workaround not a solution. So how do I control that behavior?

ASP.NET form has a defaultbutton property that specifies which button is clicked when ENTER is pressed. Just specify your button ID there. E.g.
<form id="form1" runat="server" defaultbutton="MyDbQueryButton">

onclick functionality of a button in a page should be called when user click on 'Enter' button on the keyboard

I have a C# .net application in which 3 text boxes and 1 button is there. When I fill the form and click on 'Enter' button on the keyboard, the button onclick functionality is not called by default. I need to call the button onclick functionality when the user clicks 'Enter' button on the keyboard. (These controls are in a usercontrol and it is populating in an aspx page).
Why its like this and how can I resolve it?
I am using asp:Wizard control here.

The control asp:Panel can set the attribute "DefaultButton" to the ID of a button, that will be triggered when pressing enter. Could that be of help here?

How can I set up my winform button so that I can either click the button or press enter

I have some buttons on a winform that I would like to have the option of either clicking the button or press enter but I cannot figure out how to do it. Is it even possible?

Set the AcceptButton property on your form to the button you want.

If you want to make a button the default button on a form you should set the property AcceptButton.
In this way, if another control in your form has focus, pressing enter will close the form.
The same process is valid if you want a cancel button (a button connected to the Escape key). This time you set the CancelButton property on the form.

How to generate buttons dynamically

I have one table with some records. My table like this
WFID clientID WorkflowName workflowsteps completedstep
12 15 print cutting,printing,lamination -
Workflowsteps will vary depending upon the workflow name.
In completedstep column it will show the completed steps. For example: if cutting and printing is done then it will show cutting,printing
Now I want to create dynamic buttons with the name cutting, printing, lamination
All the button will be disable by default only first button will be enable and clickable if I press first button "cutting" then its color should changed to red and The next "printing" button will be enable. Same process will repeat for each dynamic button.
How to do this in ASP.net?
:)

Put cutting button inside completedstep column.Do your code in gridviewrowcreated event, and enable only first button.Keep a printing button their also after cutting button make it visible false.Create a cuttingbuttonclick event handler method to handle visibility of printing button.
For dynamic button place a panel or placeholder inside grid.Then create button from codebehind and add it to the panel or placeholder.
Put this code inside gridviewrowcreated event.
Panel panel1=(Panel)e.Row.FindControl("PanelinsideGrid");
Button dynbtn = new Button();
dynbtn.Text = "Button Name";
panel1.Controls.Add(dynbtn)
