Parent = context.table
child = From t in parent where ...
In properties, the datasource is set to parent as well.
The bindingnavigators.bindingsource are set to child, all controls and datagrids are bound to the child bindingsoure.
Add new will instaniate a new row. It displays in the datagrids; however, it will not save. The primary key field maintains 0. As soon as I sort or call a new query the row is gone. On reload the row is gone.
I have tried ending edit in reverse order and not reseting the current item (needed to update the changes, which works correctly for some strange crazy reason). The problem exists solely with saving a new row.
Does it make a difference that there are two binding navigators? Due to space and design, I opted for 2, but I have tried the addnew on the second.
Hmmm ... Ideas? (Asked in VB too. Saw the forms forum after.)
Actually, I solved this in quite an odd manner. I added a textbox for the primary key that was linked (bound) to the parent datasource. This solved the add new.
Why the child could not aquire a key value is beyond me. I simply hid the textbox by placing it behind another control. Oh, that reminds me. You cannot set the visibility to false and the key still add. Again, another thing that eludes me entirely. What does visibility have to do with it? I could not find any documentation that linked the visible status to the enabled status, but ah well. Problem was solved.
Hey all, is there a way to detect if ANY control is clicked inside a form? The MouseUp, -Down and so on events can only be set for the form itself, but as far as I have tested i out not for any controls that reside inside it - true? Is there another way? Cheers, Dennis

False, anything that inherits from Control[^]. See Richards'[^] answer for a recursive method that loops all controls, and hook 'em up to a single event-handler. The 'sender' argument would tell you what control was clicked.
I have an installer developed in Wix. I want to execute one batch command during the upgrade operation. I added one Wix custom action in wxs file. Anybody know to which sequce should i add this for my requirement.
Are you using databinding to get the value in there, or putting in the value manually? With databinding, it'd be using the FormatString[^] property of the binding;
"Text", // the property of the textbox that we wanna bind
Properties.Settings.Default, // the object to bind to, this case "Settings""ConnectionString", // the property of that object to bind totrue));
textBox1.Databinding.FormatString = "C";
Alternatively, you could keep the value in a private variable, set it when the user is done editing, and update with a formatted version when the focus is lost. A description of the markup can be found here[^].
If the subject is "new", MSDN has an introduction here[^].

I used to be able to write bat files in my sleep. now, they are a fuzzy memory. Ok here's the deal, I need a something that I an run on start up or execute via executable, It will open a folder and merge about 50 different .reg files into registry, how ever, I want it to run silently, and no confirmation other then completion.
I am sure I can put the files in a .dat and insert from there. any ideas on what I should use?
Throw me a bone. Flame me. I don't mind, as long as you don't mind getting flamed, torched, nuked, back.
