I have a combobox which contains a sample of names selected from a table.Currently the default name displayed in the box is the 1st name found in the table. What I would like to do is display the name of the person who is doing the selection as the default. The name is stored in a public variable 'PubName' and I do not want the user to be able to type into the combobox themselves.Is this possible?

My program has a textbox and a listview. In the list view i have added three person's name, John, Kat, Adel.
How do I make it such that when John's name is selected in list view, John's age is automatically displayed in the text box?
And when Kat's name is selected in list view, Kat's age is automatically displayed in the text box?

I'm writing a standalone application in VB.NET using Visual Studio 2005. I want to display/hide a bunch of Buttons based on the selected value of a ComboBox. Each selection would have a different set of Buttons to display, and I'd like to have them arranged in a nice grid.
Driving a TabControl with the ComboBox value would be the kind of behavior I want, but I don't want it to look like a TabControl to the user because it might be confusing.Is there a way to do this?
Basically, I'd like Selection1 of the ComboBox to show Buttons 1-4, Selection2 to show Buttons 5-11, Selection3 to show (maybe) Buttons 1, 3, 5, 6, and 8, etc., have them arranged nicely, and have the GUI show only the ComboBox and the buttons.

i got another problem with this selectionchanged event in datagridview1, i set my datagridview1 to Selectionmode = fullrowselect.
the problem is i got nullreferenceexception error whenever i clicked the column header, so meaning selectionchanged fire when i click the columnheader since columnheader will have a row value of null the exception appears, i tried to catch it but ending up in messy situation which the code i written doesn't run right. is there anyway to prevent user from clicking column header but it still visible? but if i do that user cant sort the data right.

Is there a way to prevent the SelectionChanged event from firing when adding rows to a DGV programatically? I am adding rows in a loop & the SelectionChanged event fires twice, which is causing me problems. I only want it to fire when the user clicks on a row.

why the SelectionChanged event fires when adding the first row to a DataGridView? Subsequent adds do not fire this event ... only the RowsAdded event fires after the first row is added.

I have a DataGridView that I am adding rows to programmatically.Normally, when I add the first row of data the SelectionChanged event firesBut my Grid is anchored to the top and bottom of the form and when I make the form smaller such that the height of the Grid is zero, the SelectionChanged event does not fire when adding the first rowIs this by design? It doesn't seem logical to me.
With DataGridView1
.Rows.Clear()
.Columns.Clear()

I have a datagridview and some code that will seek out the appropriate row and select it programmatic.
For intIndex As Integer = 0 To ofrmMasterList.dgvMasterList.Rows.Count - 1
If ofrmMasterList.dgvMasterList.Rows(intIndex).Cells(0).Value = strMasterID Then
ofrmMasterList.dgvMasterList.Rows(intIndex).Selected = True
[Code].....
The above code works like a charm, except that my selecting of the right row does not fire the datagridview 'selectionchanged' event like it would normally do if I just clicked on it manually.
what I need to do to get the grid to fire off this event after selecting a row with code instead of a mouse click?

In the following sample, I create a collection of objects and bind them to a DataGridView. When the button is clicked, I .SuspendBinding, then remove all the records, then .ResumeBinding. The DataGridView1_SelectionChanged event is fired when I remove { m_dataSource.RemoveAt(pos) } the selected row of the Grid. Why is this? I would think that .SuspendBinding() would stop any events from firing through to the grid. If not, what is the point of .SuspendBinding()?
Imports System.ComponentModel
Public Class Form1
Private m_dataSource As New BindingList(Of BusinessObjects.Person)

I have problems figuring out how to separate a single person to display on my listbox.
I am currently working on an assignment called "Douglas Resort Reservation" and we are supposed to select a query from the combo box Guest Search. For example, when I select Barb Allen, I get the info to display properly, which is good. But, I still have a problem.
When I try to click my button 'Prepare Invoice', I want Barb Allen's info to be displayed in my listbox 'Invoice'. But, now I don't have that complete. I have a whole list of items generated when I load my whole thing from my Form Load event from the textfile RESORT.TXT. I get a whole list of items instead of individualized items.
My question for you is: "How can I get just ONE name and person's information to show up?" when I press the button 'Prepare Invoice'.[code]...

How can I get the sum all the values a user enters into TextBox1 to display that sum into TextBox2.The user is going to enter one value one by one. The user enters '1' into TextBox1, therefore, TextBox2 should display '1'.If the user than enters '2' into TextBox1, TextBox2 should display '3'.If the user enters '2' into TextBox1, TextBox2 should display '5'.And so on.TextBox2 should only display one value at a time, not one after another.I am using double because I need decimal places.I have a ListBox1 where it displays all the values entered by the user in rows one by one, but I prefer not to use the ListBox1 to get the sum of all the values entered in TextBox1 and to have TextBox2 show that sum. Because in that ListBox1, I have few other things in there, like Strings, which will not allow the sum of all the values entered in TextBox1 to be calculated and displayed in TextBox2.Not sure if this matters or not, but I thought it might.So only need TextBox2 to have all the values entered in TextBox1.If 1 was entered in TextBox1, TextBox2 shows 1.Then 2 is entered in TextBox1, TextBox2 will show 3.
