I already tried CollectionChanged but that does not detect any item changes. I wish you can give me any code example.

Thank you very much sir, for your reply, I want to mean "changes to the device list which should propagate down to the combobox"

Suppose, my list contain 5 strings. And that list is bind as Combobox item source. Now tell me how I save that in settings file at run time. Please help.

Very brilliant answer. I wish you can give me any code example. Just see the last part of my question where I already told about the Combobox item source.

Somehow we need to relate this with settings file.

But, unfortunately that's not working when Combobox content are dynamic that's why I asking this question in this forum. If you know then please tell me.

Thank you very much for understanding my problem. Actually, my combo box content are showing available audio devices. May be sometime different type of devices are available that's why combo contains totally different items next time you run. And if there no item changes happen then the previously selected option should be shown in the combo box when I restart my application.

If any item changes happen then the combo box should go to the "System default".
But still, I want to save from a Dynamic content can you please tell me? how can I do that?

I use the Code behind method to add Content in combobox in this way.. this.cmb1.ItemsSource = lcv; Just see the first part of my question, where I give the List<> code.

Dear sir, sorry I know slightly about ObservableCollection that it's best to use for updating the UI But in this type of situation I hardly have any idea to implement it. Can you please help. I definitely accept your answer.

I already know that, Can you please Complete the full code after applying Observable Collection to implement data binding. So, that I accept your answer.

Thank you very much sir, for your crystal clear explanation. Your code does not solve my problem.

Here is the question link where I described each and every part of the question is clearly explain which I asked on Microsoft Question and Answer Forum :

https://learn.microsoft.com/en-us/answers/questions/1092033/how-to-change-foreground-color-of-a-combobox-on-se.html

Thank you very much sir, but there nothing detect when I do debugging because my application don't crash anywhere, it's just does not add the attach behavior.

Can you give me another solution? a Costume class may be the solution.

His, answer is wrong if you read all comments then you clearly understand. His code has Data Context error, though I solve this problem later by doing datacontext="{Binding RelativeSource={RelativeSource Self}}" this data binding.

But still I don't get the desire effect I want.

Can you please solve my question?

According to the attach behavior, the IsFocus should false when mouseover true but I don't get this effect in my Combobox.

If you want to see the full source code then I already post on Microsoft Question and answer forum. I also post required GIF image there.

Hi, sir Can you write an attach behavior for IsFocus property? I need your help.

Ok, I am sorry for advocating for MVVM. Now, tell me how I implememnt this using a user Control. Give your answer with proper code and I will accept your answer. Please solve my problem, I stuck it here for my project for a long time.

This is the answer I want. Brilliant explanation. Can you give me the proper code on How I use the Preview tunneling? Because I don't want to use a user control with a click handler (for each item), that's violets the MVVM design pattern. I already given all of my code. Kindly give your full code for applying preview tunneling.

Thank you very much sir, for your reply. I already do that what you saying. Just give me a code solution of my problem if you or any of your friends and family member is a WPF developer then tell them my issue and kindly share my question link with them.

Can you have some demo code because it's too much complex. Give your answer with proper code and I definitely accept your answer.

I also try to use the PreviewMouse Down event but the result is same. I don't want to use any timer delay that's why I use MVVM pattern. If you have any code solution then please tell me. I am in great trouble.

Thank you very much sir. I understand that I should do this from Code behind. Can you please give me the solution with proper code. If you do then I shall be grateful to you. You also give me any example, links etc.

I understand that and I also know that sir. I don't use any long sentence as button content in the ToolTip content. Due to design purpose I have to do it in this way. By the way it's not my project. It's our office project so, the client wants that's way. Please help me. And kindly read the stack overflow post which I given as a link.

If you know how to achieve by using a trigger then please help me. Don't give your personal suggestion. If you know that then please tell me otherwise just ignore.

Thank you sir. My problem actually solved in Stack overflow but the problem is using an third party NuGet packages which is unfortunately not available now.

Can you please tell me that How I can solve this using any trigger? or Data Binding

Here is the Stack overflow link :https://stackoverflow.com/questions/63510347/tooltip-appears-instantly-in-wpf-does-not-trigger-initial-delay

Can you please post the code what you tried? it helps me a lot.

Thank you sir for your reply. But TextFormattingMode does not solve my problem. I hope we have to do something in data binding. If you know about multi binding then please help me to solve this problem.

Thank you sir. If I run those binding separately then that bindings are perfectly working. That means there no error in binding but only error comes in the multi binding. You already know what I want, that means I want font size =10 and the font size should be clearly visible in every screen resolution.

I suggest you to give me your binding suggestion regarding the Font size, because you already solve the problem of the converter.

Thank you sir for your guide. But again I face the error in the converter. I get some error like this unable to cast object of type 'ms.internal.namedobject' to type 'system.iconvertible.

Thank you for your help but your code is not working. As soon as I lower the screen resolution the text became blurry. Previously I solve this by binding to {x:Static Application.Current} to the font size. Your double collection is not solve my problem. Please give me a solution to add this line in the multi binding. <binding source="{x:Static Application.Current}" path="fontSize" mode="TwoWay">

the fontsize is just like other number. I both tested with int and double but the error "Specified cast is not working" is same.

Thank you sir for your reply. Your code is slightly working But I get the error "Specified cast is not working".

Please kindly give the full source code example. Because Path=TextSize is not working.
