How to check if bindingsource contains records? 
|
|
|
|
|
The bindingsource will not contain records directly; you would have assigned a datasource previously. Probably a list or a datatable

Try MSDN[^].
"The Count property gets the number of items in the underlying list represented by the List property as modified by the value of the Filter property."

Dear Sirs,
I need to restrict the colours and the fontname of a control that will be displayed on a property grid.
For example, in my application I only will allow the user select on of the follow FontNames for a control in a propertygrid: {Arial, Calibri, Comic Sans MS, Arial Black, and others}.
The same will be happened with the allowed colours do be selected.
I would also know the easiest way to hide all properties, except "Size", "Location", "Font", "Backcolour", and some properties that I've created. I've learned to use Browsable(true/False), or using BrowsableAttributes. But there are some properties within an Attribute that should be hide.
Thanks,
Almerindo Paiva

Create a proxy; a new class that contains the properties that you want to set.

Hi Does anyone know of a good book that actually has C# Coding in it to use as a good reference book. Thanks.
|
|
|
|
|
Almost all of them, provided they do not have multiple exclamation marks, the words "for dummies" or the word "in x days" in the title.
Have a look the the Wrox[^] selection, or Addison-Wesley[^]

CLR via C# is a very good book if you want to spend learning more time about the internals of the .Net framework (rather than the programming language itself).

What I really want is a Reference Guide to the actual codings thanks

The MSDN C# Language Reference[^] is all you need, then. Most pages have sample code, as well.
Whew! I had to click twice - once to get to Google, and the other to get the page - to find that for you. I'm pooped... time for bed.

I go with Abhinav, CLR via C# is still best book for me. If you do not have concept clear, example does less of purpose.

Go for the Nutshell book - see my post (and the one before mine) in this thread.

When this came up a month ago or so (again), I did a bit of research and found an excellent book. In fact, I bought it myself. The OP that time was looking for a book that included exercises and answers, just like a real textbook, and this one has them. The one thing it lacks, which might be a good thing for a beginner, is much coverage of data access. Although that's most of what I want to master, lengthy discussions of ADO really detract from learning the fundamentals of the language, and are better left to specialty books. It does an outstanding job of teaching the essentials of the language, and is specifically targeted for Visual Studio development for Windows. Although I've been writing functional, if not fancy, apps in C# for years, I've learned a bunch from this text, and hope to spend some quality time with it soon.
It's published by Wrox Press (unsurprising, as they produce some of the best programming books available, consistently), and entitled "Beginning Visual C# 2010." The ISBN is 978-0-470-50226-6, and it's available at Amazon. It's also dirt cheap.

Jeffery Richter's book
Applied Microsoft.NET framework programming
CLR via C#
Best according to me...
|
|
|
|
|
|
I've found the C# 4 Nutshell[^] book to be an excellent reference.
