Description John Miller [MSFT] 2014-06-13 13:52:24 UTC
## Overview: 

    Using the VS iOS Designer and adding an event handler for a button from the Properties -> Events menu a MT4117 error occurs at compile time. Double clicking the same button to add an event handler for Up Inside does not reproduce this issue.

## Steps to Reproduce: 

    1. Create an iOS project with a storyboard file.
    2. Add a button to a view. 
    3. Go to the Properties menu for that button.
    4. Go to the Events tab, and for the Up Inside event, type in an event handler name e.g. Test_Click
    5. Save and build.

## Actual Results: 

    Error 1 MT4117:The registrar found a signature mismatch in the method 'TestApp.MainViewController.Test_Click' - the selector
'Test_Click' indicates the method takes 0 parameters, while the managed method has 1 parameters.

## Expected Results: 

    No error.

## Build Date & Platform: 

    XVS 3.0
    VS 2013

## Additional Information: 

    If you double-click the control to add an event handler for TouchUpInside, it will work fine. The difference in the storyboard shows this:

When manually adding the event handler through the properties menu:
<action selector="Test_Click" ...>

When adding via double-clicking the control:
<action select="Test_Click:" ...>

The ":" is missing in the first. 

This does not happen in Xamarin Studio.

I have tried this issue but I am unable to reproduce this issue.

Steps to reproduce this issue:

1. Create a iOS "Single View Application" on VS 2013.
2. Add a button on MainStoryboard.storyboard file.
3. Add an event to button (select button => on property menu => select Event tab => add handler for Up Inside event).
4. Save and build the project.
5. Project is building successfully.
