Validation error tooltip floats around when moving window about mahapps.metro

[sirWest]

I would love to test/debug this but frankly I have no idea how to create a simple test code to show this invalid message box :) Can you give some simple snippet to insert to MetroDemo for testing this issue?

Here is a tutorial: http://codeblitz.wordpress.com/2009/05/08/wpf-validation-made-easy-with-idataerrorinfo/

I think the best way would be to implement IDataErrorInfo in the MainViewModel class and create a new property for the textbox to bind on.

Sorry, I didn't had time the past days. I've created an example code for the error validation at my "validation-test" branch.

Now, when you enter the word "Test" into the textbox with the username watermark, the validation error message ""Test" is not a valid input." appears. Now drag the window around and you can see that the message remains at it's original position and does not stick to the textbox.

Woops, I've just noticed that I deleted the branch for testing this issue.

I have now recreated it, just follow the steps I explained in my last post.

Still no one trying to fix this issue? Come on guys, this is easy to reproduce.

You're welcome to send a pull request or post a complete reproduction. But come on, that would be being helpful.

Why did this got closed? :(

because nobody is working on it, @ktei was good enough to whinge about it, and I don't use validation stuff so I have little desire to fix it.

Oh, ok, I just asked because I saw the "useless issue..." label and don't know what I did wrong

This issue can be resolved by using the "Validation.ErrorTemplate" instead. Remove their validation template (ValidationErrorElement and storyboards that go with it) and use the code below.

Example:

@punker76 improved the validation bits a while ago. You shouldn't need to delete the ErrorTemplate.

See #357 for details.

i agree with @rasheedb that this is still a nasty behaviour. the tooltip is not moving or closing if i move the main window.

[shiftkey]

@punker76 ok, I've reopened it then now that I can see it is still occurring.

[punker76]

@shiftkey i think, if we replace it with a Validation.ErrorTemplate we lost the cool tooltip feature. maybe is this a bug in wpf, because the current validation feature (style) is the same as by msdn.

[rasheedb]

You can still have the "cool" transitions if you like. I ended up doing the following, where the message shows when the user has clicked (focus) into the control only. I do a horizontal slide to show storyboard.

(sorry about not known how to post code in these comments)

[punker76]

@rasheedb that's not the same! the errorMessage is only shown within the MainWindow/Control. so if their is not enough space it looks nasty (so you must have enough space around the control with the error). the tooltip solution shows the error also outside the window (no extra space around the control is necessary).

look at the help for posting code here: https://help.github.com/articles/github-flavored-markdown

Unbaked the code in that png... Didn't fix my issue though :P
