Bind A Dataset To A Combo Box Through Code?
Apr 6, 2011I'm using Visual Basic 2010. I have my dataset in my program. I'm have several combo boxes on the form that I was able to bind the particular table with the information from each table to most of the combo boxes by dragging and dropping them onto the combo boxes. However, one combo box in particular must be populated by code. When a user selects, let's say "a" from one combo box, I need the next combo box to display information in certain tables only, based upon their choices in the previous combo box.

View 6 RepliesForms :: Generate A DataSet And Bind It To A Datarepeater Object?
Aug 30, 2011This is my first post here so forgive me if I am not following any correct protocols. I am attempting to generate a DataSet and bind it to a datarepeater object. I had been doing this at Design Time and was getting an error message when filling the dataset when the form loaded. So I am basically createing the dataset in my code now when the form loads and binding it to the datarepeater. However, when I attempt to bind the dataset I get a NullReferenceException - even through I know that there are 60 rows of data in the dataset table.
[Code]...
As you can see i have several debug messages in there. I get the error on the last line when setting the datarepeater data source. I try and get data for a specified lot - if it doesn't return any values I create some values in the datatable and add them to the DB. On first load when there is no data this works perfectly. If I then close the form and reload it, it will display fine. However, if I change any of the data (database is updated) and then go back in again, I get the error above.

Bind A List Of Custom Objects To A Listbox Control?
Jun 25, 2010vs2010 vb.net WPF project
This is an experiment to learn something.
I have a class called logitem
it has a datetime property, and a message as string property
I have declared myLogEntries as List(of logItem)
I have a ListBox.
Ok now what?
I have searched but i am getting lost in all the examples.
I have set the ItemsSource=myLogEntries
I think i need a datatemplate or maybe to specify binding source.
I am doing all this in the wpf form loaded event.
I guess i need a sample code for binding a list of collection to a listbox.

VS 2010 : Populate Listbox With Dataset Created In VB?
May 1, 2012i have a Userform that I created in MS Word that automates almost half my job. I'm just looking to re-create this form in VB.Net so that I can keep up with the trends.What I did previously was load a listbox based on the contents of a data table in another word document. I've searched for other methods of creating a datasource in VB 2010 Express but I'm unsure how to load the contents of a dataset or datatable as opposed to a table from MS Word. Ideally, I'd like to abandon using Word tables and create a dataset in VB and load a listbox based on that. I do not have a copy of MS Access and I'm unfamiliar with MySql, which I'm guessing would are the easiest methods of loading a dataset. I also thought that maybe if I could create a seperate form (let's just call it form1) specifically for entering new data and saving the form as data is added, then linking the datasource from that form to a second form (form2) that has the listbox that will populate with the contents from the data in form1.
View 11 RepliesDataset To Retrieve Some Data From An SQL Database And Then Uses It To Populate A Listbox?
Jan 19, 2009I have inherited some code from an external contractor that I have to modify. Firstly, he uses a strongly typed dataset to retrieve some data from an SQL database and then uses that data to populate a listbox. I have decided to use a dropdown list (as the user can only ever select one value at a time).This is the code that populates the DropDownList
Private Sub FillUserComputer(ByVal userId As String)
Try
TraceDebug("Begin FillUserComputer"[code]....
This works well for the first two entries in the DropDownList. However, whenever I select one of the other options and click the Send Request button it "jumps back" to the 2nd entry in the list and sends that data instead, completely ignoring the option I selected.I think I have narrowed down the problem to the fact that the DataValue for the second entry in the list is a Null value.

View 5 RepliesDataGridView To Bind Or Not To Bind?
Sep 2, 2010I'm currently developing an application with a reasonably complex DataGridView that allows the user to build the lines of a sales document: Quantitiy, Description, Price, etc with some additional fields to help calculate price based on cost or discount i'm sure you get the jist - all this means we're not just diplaying data but adding and manipulating it - It also means there's mainly decimal fields, nit just simple text fields
Now, i'm new to VB.net, so i've perhaps done things a bit backwards during my learning curve, namely designing and coding my DGV before creating the underlying database table and binding to it - so as i'm sure you can image there's a bit recoding to do to allow for the fact that it's now bound to a datasource.
I'd got the DGV working just how a wanted it to, but now that i've bound it to a datasource i'm hiting multiple problems with: Formating the appearance of figures in the DGV Problems with blank fields while enering data (before the i try to save the data back to the database) How the DGV is functioning - it seems to behave differently when adding lines to a new sales document than it does when adding lines to an existing sales document
And given that when saving edits to an existing line i need to provide a valid update command i'm begining to think that it might be easier to scrap the databinding altogether and just Select, Add and Edit the database with code rather than binding the DGV in the IDE
I've read various threads about avoiding databinding due to it's limitations, but i've also read that it's far better in later versions of Visual Studio and .net. and i'm using VS2010
I'd just like some advise as to whether my gut feeling is right or whether i should persevere with databinding the DGV. i've noticed some quirks of databinding while working with other controls such as text and combo boxes, but i've overcome these and the result seems to be easier than coding the data transfer manually.
But i'm really struggling with databinding the DGV and the fact that i'm dtatbinding to a seperate table to the rest of the controls is leaning me away from databinding
ListBox PreferredHeight - Make ListBox Calculate Correct Integral Height Before ListBox Is Made Visible
Nov 19, 2009If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ListBox1.Visible = False
