when the user clicks on the add button another form launches, which enables the user to add student info such as name, address, course, start date and end date, this information is then written to class when the ok button on that form is clicked, and then displays the data on the initial form in data grid. the user can add multiple entries and they are all displayed on the intial form and a the data grid is populatedwhen any of the rows in the displayed grid is selected, and the update button is clicked then the same form launches as the previous one and but this time its in the update mode and pre populates the form with the inital values.

View 2 RepliesI am using vb 2008, DataBound Controls and typed dataset. My form is having Group Box (initially hidden) and some text box, combobox controls for Data Entry, and the code is
bsSales.AddNew()
txtCreditDays.Text = 20
dtDueDate.Value = dtSalesDate.Value.AddDays(txtCreditDays.Text)
cboGodown.SelectedIndex = 0 '
Default
gBox.Visible = True
dtSalesDate.Focus()
I have set the combo box to select the 1st record in the list however, when the next Statement that is "gBox.Visible=True" is executed, the Combo Box is again set to -1 position. Why is it?
Do I really have to go through all this just to find out what item has been selected in a ListView?

This is a VB .NET application where we are showing the output of a SQL statement in a Datagrid view. using .NET 2005.We need to get the seperators of the headers on the grid control to be the same colors as the GridColor on the form. See the picture below:We've tried looking through all of the properties of the DataGridView control, and found some interesting things that looked promising such as the DataGridViewAdvancedHeaderStyle, and DataGridViewHeaderBorderStyle, but none of it seems to allow you to change the colors on it.Does anyone know how to do this without remaking the entire thing with a GDI+ control?

The split seems to be working fine but the issue i am having is when I populate the datagrid it is growing in height and changing the splitter instead of leaving the height alone and adding scroll bars.
What simple thing am I overlooking?

The first would be, how would I go about making each index in a list box an integer or decimal value? For example, If I wanted the 1st (or 0) index to = 300 and the next one (1) = 400. The next question that I have is that, if I had two or more list boxes with each index as a certain value as listed above, how would I go about adding up the total for each index that is selected?
View 10 RepliesI need a way of converting the listbox.selectedindex into hex and then writing it to a file(The writing is done using PackageIO.writer). The weird thing is the code i use works for most of it but on some of the writes and conversions it just converts the selectedindex to 00 when its not.
Dim Writer As New PackageIO.Writer(Filepath, Endian.Little)
Writer.Position = &HE24A
Writer.WriteUInt16(Convert.ToByte(ListBox3.SelectedIndex))

I have a DataGridView containing a large number of columns. I want the users to be able to select multiple columns and then select a menu item to hide the selected columns. For example a user might selected columns 5 through 10 and I want the program to hide those columns. I know how to hide columns, one at a time. I can get the count of selected columns but I have not figured out how to get the index to the left-most selected column. Trial and error is such a slow process.
Considering the huge number of options offered by the DataGridView tool, it would be nice if this forum had a special category for the DataGridView (common to VB and C#).
Finally I got the desired results but it took a lot of coding, looping through the selected cells to find the one with the lowest column index, then a second loop to count previously-hidden columns, then a third loop for hiding the selected columns, stepping past previously-hidden columns and declining to hide frozen columns.
how can i get the index of selected row in listview in mouse up?
