I need a little advice in manipulating DataGridView in Visual Basic .Net. This is my first time playing with DataGridView. My program is to load a .txt file containing data of every room in a building and display them in the DataGridView. Here is a portion of the file showing 2 rooms:
A room is a one-line string that ends with an endline character.I have no problem with loading the file and getting all these information. I store data of each room into an object of class Room, and put them in a list.Right now, I put all of the properties of the room into the data grid's columns like this:
Now, how can I put all these rooms' data into the grid? I tried follow [URL].. at first, but setting DataSource to a list of class Room imitating from the given link doesn't show anything in the grid view.How can we tell the program to link rows of the grid to a list of objects? Or am I doing it wrong?
I have a vb.net window app that has a number of combo boxes on it. These are being populated from a number of XML files and all this works like a charm. The problem i have is when it comes to putting the comboboxes in a datagridview. I have set up my columns and have set the first column to be a combobox but i'm having problems referencing this so that i can set the datasource to populate it.
I've looked everywhere but cant seem to find how to reference this control. Once this has been selected it will populate a second combo box based on the data from the first. I think i can sort this out, if i could only work out how to set the datasource of the first combo programatically.
I have attached a picture of yahoo Messenger with this Thread and highlighted the 2 text fields and a button with red line. The problem is that I have seen a small program in the computer of my friend. When He double clicked on that program, it (program) automatically puts the User ID and Password in Yahoo Messenger relevant fields and automatically presses the Login Button. I have tried much to get the source code of that program, but cant.
