I am trying to bind a DataGridView control on my windows form. However, it doesn't appear to be working. Am I missing a step somewhere? I cannot get the objects in my collection to display in the DatagridView.
Here is a sample of my code. I have not included the Person class.
'CREATE A COLLECTION OBJECT.
Dim p As New List(Of Person)()
'ADD PEOPLE TO COLLECTION.

View 4 RepliesUsing 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?

View 3 RepliesI have 2 tables:tblcode and tbltransaction tblCode with 2 fields:Code and Description with data like
Code Description
A test1
B test2
C test3
and tbltransaction with 4 fields:transactionID,UniqueID,Code,Value with data liketransactionID and UniqueID are the primary keys)
transactionID UniqueID Code Value
120 1 A 0
120 1 B 1
I want to write a query that outputs:
transactionID UniqueID test1 test2 test3
120 1 0 1 0
so because tblcode has 3 fields I have 3 columns which are test1, test2 and test3(the descriptions of Code A,B and C) i tried to use pivots but it didn't work for me since I don't know in advance the number of rows in tblcode?
I have a form called studentForm which has a studentCombobox, studentTextbox and a studentDatagridView
In the constructor of the studentForm I need to bind studentCombobox to the StudentbindingSource of the main form and to bind studentDataGridView to appropriate binding source in the mainForm.So that this datagrid view displays all the bookings for the studentID currently selected in studentComboBox
studentComboBox.DataSource = MainForm.StudentBindingSource
studentComboBox.DisplayMember = "StudentID"
studentDataGridView.DataSource = MainForm.StudentDataSet
studentDataGridView.DataMember = "Names "
This is the code I wrote in the constructor
I am sorry to keep bothering you about this damn DataGridView control ... As you might have noticed I am having a hard time with the DataGridView control ... My latest problem has to do with updating the data base file (Access) through a DataGridView control .
Up to now I have managed to successfully edit an entry in the DataGridView control and moreover to successfully update the data base file itself .
The above form and its code work fine . The problem starts when I am trying to run the code of the Update button from another form .
You see , I have another form , through which I change the contents of some of the cells in the DataGridView control (back in Form1) . What I want next is to simply update the data base file itself , just like I was doing with the button in the first form , after I manually changed the cell in the DataGridView control .Thus , on the second form I have a button with this code :
Form1.Button1_Click(Nothing, Nothing) (of course the Click event is declared public)I have also tried :
Form1.Button1.PerformClick()
but still nothing ...Although Form2 successfully changes the cells back in Form1 , the data base file itself does not get updated ...If I manually press the Update button in Form1 I once again successfully update the data base file , but I want to do the whole thing by calling the Update button from Form2 .
I'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
I have a basic Windows form with one Crystal Reports form veiwer control on it. When ran on the development machine it displays the report fine.After build and publish the application is now installed on a user PC. I am getting an error that the Crystal Decisions. Windows. Form version 12.0.2000.0 can not be found. All the Crystal dll's are in the install directory but none of them are being installed in the install machines GAC.Am I setting my publish output up wrong, may references wrong, or is the local GAC files the problem. The message is so criptic, it doesnt really point me in the right direction.
View 1 RepliesIs 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 was thinking. is it possible to bring the rows that we click at datagridview and bring it into another form. which mean i click on a data that are on the datagridview, then it will pop up a form, inside the form, there will be have the data we have click on the datagridview, and we can edit and save at that form. Can it be done? if yes, how do i gonna bring it over? i only manage to make a windows pop out only. but cant bring the data over.

View 2 RepliesSuppose I have a label control on a windows form called "UserName". How can I refer to that label programmatically using the label name? For example I can do:
For each ctrl as Control in TabPage.Controls
If ctrl.Name = "UserName" Then

Next
This seems quite inefficient. I would like to do something like: TabPage.Controls("UserName").Text = "Something" I did some googling but couldn't find a satisfactory answer. Most suggested looping, some said .NET 2005 doesn't support direct refenece using string name, and FindControl method was asp.net only...
