Asp.net - Allow Paging On Gridview With Custom Databinding In Place?
Mar 17, 2012I am a bit lost in concept how to implement what i want to do. I have a gridview, a checkboxlist. I bind the gridview on the page_load. Everytime user choose a checkboxlist, the gridview rebind as well. I have something like this now. This is not the actual code. Thanks so much.
[Code]....
So what do i put here in order to allow paging ? basically, I have 2 datatables in the above example. In the actual code, I have about 5 datatables with 4 checkboxlists. I can't use Datasource control. I need to do it in codebehind as all code already exists.
How To Place ASP Custom Controls In Separate Tab Panels
Dec 23, 2011I have a asp.net placeholder which gets populated with many custom controls, each custom control is a summary of a location containing various facts and interactions. When directly populating the placeholder with the controls they get added one under another down the page. I'm trying to find a way to place each custom control generated in a loop in its own tab (any sort of tab, asp.net/jquery ui etc) so that the user can select the summary they wish to view instead of having to scroll down the page to find it. (I'm using ASP.NET and VB.NET)

Custom Made Bindable Structure?
Oct 1, 2009As a coding exercise, I would like to know if it is possible to build a bindable data structure that would have a dynamic collection of field objects, in which each field not only would have a specific data type, but also would hold the value for that field. That is, is not like a DataTable where you can have many rows, I only want to manage a single collection of values.

View 6 RepliesCreate A Custom Tree(view) Structure?
Jan 1, 2012I'm looking for a way to create the treeview structure in memory with a classes, so I can loop through them, like with a collection and easily load the data into a treeview, listview, datagridview or simply work with the data in the background.
There's a treenode class that I could use, but I've noticed that when I have a lot of data in the nodes, it has a lot overhead when for example serializing, because it also saves the checked state, imageindex of the nodes and things like that, which I never need. The saved file is about 10 times bigger than the actual data, which is not acceptable.

VS 2008 Navigating My Code - Flow Can Jump From Place To Place
Mar 11, 2010Like I imagine everyone, I often have problems navigating my code because the flow can jump from place to place. For example, if my code calls routine1, and I then want to go to routine1's code, I know that I can click in the dropdown menu and it will take me to that sub. But wouldn't it be easier if I could somehow right click on the call to routine way and select something like 'take me there' which would transport me from the function making the call to the code for the function being called? Then it would be easy to hop from place to place.

Class Structure - Large Structure That Has Lots Of Properties ?
Jan 5, 2010I'm new to VB 2008 after having spent a long time with VB6, so I apologize if this is a stupid question. But I'd really like to have this straightened out.
Let's say I have a pretty large structure that has lots of properties.
Code:
Now say that I want an internal database with about 10 instances of this structure total, describing, say, 10 different products that a store sells. When these values are loaded from a database, they remain totally static. (However, they can be different each time a program loads)
Now say that I have a class. Each instance of this class is a type of that BaseProduct structure. Meaning, each instance of the class pertains to one of the 10 types of products that the store sells. However, this class has additional properties that pertain specifically to each instance, which are not static.
Code:
Now, the problem here is... If I have 200 different transactions, each one contains an instance of BaseProduct. BaseProduct is HUGE, and is largely redundant (only 10 types possible), so I think it's a little silly to include a whole copy of it with EVERY transaction. However, the Transaction class really needs information regarding the base product it pertains to. Is there a way to, instead of declaring a New BaseProduct in the Transaction class, to simply make one of the properties of the Transaction class a pointer to a BaseProduct variable?
In VB6, I would accomplish this by making a BaseProduct(10) array, and then giving each Transaction an ID number referring to an entry in that array. But in VB 2008, using class structure, this is impossible. I can't define the BaseProduct(10) array outside of a class in a namespace, and if I define it in the actual application's form, then the class loses modularity since it relies on the application that's using it.
Converting Structure Within Structure To Byte Array For Socket
Aug 29, 2009I am trying to communicate with an external device and i am trying to send a byte array to the external device via sockets but i am always getting a response the message size is too small so i am not sure what i have done wrong. Between the data type there should be no alignment present and all numbers are represented in little endian format. The char array is not null terminated as mentioned in the protocol specifications.
I have to send data based on a struct that embeds 2 other struct. So here's my vb.net code for the struct used to convert to byte array and the sending part.

Place All The Objects In The Same Place On The Screen
Nov 30, 2011I am learning Visual Basic 2010 and I am working on a space combat program for my own education and amusement (a simulation of the Honorverse space combat system). I have a routine to add ships to the enemy ship roster and then place them randomly on the viewscreen. When I step through the sub with the debugger, it works fine, but when I run it without stopping, it wants to place all the objects in the same place on the screen. It's actually assigning 2 random numbers pertaining to the size of the viewscreen and assigning those numbers to GameObjectScreenLocation through GameObjectWorldLocation.X and GameObjectWorldLocation.Y. The objects are fully initialized to 0 in their constructor, FYI. Code is below:
