I created save,delete,next,last buttons.How do i correspond them with the navigator control.This is what i need to do as per the assignment.Both the customer and order tables should have buttons which correspond to the BindingNavigator control. There should be NO BindingNavigator controls. The user should be able to save, delete, go to the first or last record, or go forward or backward one record at a time.
View 1 RepliesI know I've done it before but I'm drawing a complete blank on this.Where can I modify the code for:
BindingNavigatorAddNewItem_Click
I need to add a try catch block to it because if the user clicks on it twice, it tries to add a second new blank record and throws an exception.
I'm using a SQL database and I want to bind five tables to one Binding Navigator.
View 3 Repliesi want to control the functionality of moving the records thru binding navigator in vb.net
for example, on click of next button in navigator, i want to check some condition, if condition is true then move to next record otherwise don't move.
Is there a way to bind the text property of a control to an expression? I have a user control that I add to a FlowLayoutPanel. You can see I have 4 controls in the FlowLayoutPanel below. The first control is a LinkLabel and the other three are my user controls which are numbered 1, 2, & 3. I'd like to bind the label that shows the 1, 2, or 3 to the user controls index within the FlowLayoutPanel.
If I happen to remove the 2nd user control I want the 3rd user control to now display 2. I could use the FlowLayoutPanel ControlAdded or ControlRemoved events, but wanted to see if I could do some binding first.
If I need access to the value of a user control's property BEFORE PreRender, would I need to base the custom control off of one of the preexisting data controls (repeater, listview,etc.)?One of my user controls features a gridview control that is configured based on the user control's properties on which it resides. Several of the key properties alter the SQL Statement for the underlying recordsource. I'm now in a situation where the property that sets the WHERE statement for the SQL Statement needs to tied to a value in the user control's parent FormView. Think of the formview as displaying a customer detail record. The user control takes the customer's account number and then displays data from a related table such as Customer Contact Names. Since the gridview is created before the control's prerender event, working within the prerender event doesn't seem efficient.

I'm using the following code to bind watin to a webbrowser on the winform.
Dim w As IE = New IE(WebBrowser1.ActiveXInstance)
Settings.AutoStartDialogWatcher = False
w.GoTo("http://google.com")
I can see from wireshark that the page get's loaded, but the form is frozen until a exception gets thrown "Timeout while Internet Explorer busy". Is there a way to bind watin to the webbrowser control?
I have been working on keeping things object oriented for my project. Currently, I'm using a .DLL which supplies all of the app's classes to the WinForms project acting as the presentation layer.My .DLL will, for example, return a SortableBindingList(Of T) to code in a form. The SortableBindingList(Of T) comes from here. Let's assume a SortableBindingList(Of Product). Assuming that the .DLL's function Services.Products.GetList() returns a SortableBindingList(Of Product), I can easily do this:
DataGridView1.DataSource = Services.Products.GetList()
Now, the DataGridView is properly populated with my list of Products. Fine. However, there is no .SelectedItem property which gives me back my object which was selected in the DataGridView:
' Doesn't exist!
Dim p As Product = DataGridView1.SelectedItem
' Need to make another DB call by getting the Product ID
' from the proper Cell of the DataGridView ... yuck!
However, a ComboBox or a ListBox does in fact store and return my Product objects intact:
' Valid!
ComboBox1.DataSource = Services.Products.GetList()
Dim p as Product = ComboBox1.SelectedItem
Another however ... the ComboBox and ListBox do not show all of the fields of the Product object, only the value of the DisplayMember property.Is there a nice control in VB.NET 2008 that I am just missing, which gives me the object oriented functionality that I want which will actually display an entire object's fields and also return that object back when selected by the user?
I am developing a fairly large database in VB 2010 as a record keeping.

I am trying to bind a dictionary to a repeater control. I have a dictionary object which is filled with the Key (as String) and values as (Class object). I receive Object reference error when I try to DirectCast() the e.Item.DataItem to a Key-Value pair of that dictionary used for binding repeater. If you check the second screenshot, the e.Item.DataItem value is "Nothing" because of which I am getting Object reference error. What is the reason that the value is e.Item.DataItem is coming as Nothing?

View 2 RepliesI need to create a new tree view, that is linked to a particular table.
Each row in the table has a parent id that links back to the table's primary key, and that defines the node hierarchy. So that relationship needs to be indicated in the databinding.
Am I able to use the standard treeview control in Visual Studio 2008, or do I need something extra to make this work?
What I want to achieve is to Bind just some of the properties of a Control to a DataTable object.Let's say I have a Label on the Form : "MyLabel1".MyLabel is a Class that inherits from Label and adds a property "ID", an Integer, to the base class.
I want to Bind .Left and .Top properties of MyLabel1 to a DataRow in my DataTable, and I want to see them updating, everytime I change MyLabel1 location on Form. I put description and full code, so everyone can test it in minutes :
I have :
--> A Form, with a DataGridView "DGV" : The DGV is for showing at real time the desired properties of the controls I want to bind ( in this case, just one control : MyLabel1 ).
--> MyLabel Class :
Public Class MyLabel
Inherits Label

I'm trying to integrate a custom control that I built into my vb.net project. My control contains 4 text boxes Month, Day, Year, and Time. My database field is a datetime field in SQL Server 2005.I am able to bind the data, but my control doesn't work when a date isn't entered. I'm pretty sure that this is a DBNull issue. I need to be able to insert NULL into the database when a date isn't entered. When a date is entered, I want to insert that date into the database. With the below code, I can't tab out of my control when a date isn't entered.

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.

Using VB 2008. We have an app with a third party grid on it works well enough. This is a small utility within a bigger suite, and adding/updating it involves a simple EXE copy. The issue I am trying to address is that not all customers will have the 3rd party controls on their systems, and we want to avoid deploying them if we can.
Can I build the app so that if the controls are present, the app uses them. But if they are not present, I use a simpler control? I picture using a 'launcher' form that tries to load Form2 with 3rd party. if it errors, then just load Form3 with common controls. But can I even get to that point? With missing controls, will the app even load? I understand Late Binding for objects, but this is a control right on the form. Can I late bind a control and add it to form dynamically perhaps?
