Setting SelectedIndex On A Combo After Adding A Row To Datatable Not Working Correct?
Dec 17, 2009
adding to the binding source then setting the combobox to selectedIndex of newly added row is not working.the new row is in there but it does not set the selectedIndex to the specified index. but if I run the code a second time it selects it.what can i do to make sure the combo uses the specified index?
Dim drv As DataRowView = CType(Dispatch.M8CustomersBindingSource.AddNew(), DataRowView)
drv("custID") = "999999"
drv("CustomerName") = "Select Customer"

I have a typical databound Form with a bound ComboBox bound on the form Load event.I have a typical BindingSource and BindingNavigator Control with an "AddNew" button.When a new record is added to the dataentry form (i.e. not the combobox) I intend the combobox to default to the first value in the list by setting...
mycombo.selectedindex = 0
I have this in the BindingNavigatorAddNewItem_Click event but it has no effect! I also tried placing mycombo.selectedindex = 0 in the BindingSource "AddingNew" event but this also has no effect. I have discovered that the "selectedindex" is somehow inexplicably changing itself back to -1 As an experiment I added a button to the form and on the click event pasted "mycombo.selectedindex = 1".I added a newrecord then clicked this button and the combobox updated as expected. But I wont this to work as I'm adding a record!Is there a particular event where I should set mycombo.selectedindex = 1 apart from the two I mentioned?

I have a DataGridViewComboBoxColumn that I allow the user to add new items to by typing in the ComboBox and hitting the 'Enter' key. That triggers CellValidating and I do the adding there by the following:
cmbColumn.Items.Add(e.FormattedValue)
All this works well, except that it leaves the DataGridViewComboBoxColumn blank. How can I set the DataGridViewComboBoxColumn to display the e.FormattedValue?

I'm trying to have it so that when the user selects an item from the combo box, it will display the right nodes for that selection in the treeview control. For example: User selects Artist from the combo box and the treeview displays the letter of the artist. The user selects a letter and it will display all artist with last names beginning with that letter. Unfortunately when I select a selectedindex, the treeview doesn't display anyting, it's blank. What am I doing wrong? Here's the code I'm using for artists:

I have a combo box on a form. I have a SelectedIndexChanged event, that displays a message box when the combo box has another item from it selected. This works fine. However when the form is loaded, I initially want to set the current drop down box item from the database, then AFTER I have set the current value, I want this event to work. Problem is from the get go when the form loads it asks me the question as its being changed from 'no data' to then be populated with a bunch of data and an item selected.

My understanding is that if you set a ComboBoxes .SelectedIndex to -1, it should unselect any items in the ComboBox and show nothing in the ComboBox text. This is not happening. How can I get that to happen?I have 10 items in the Combobox. Let's say the index is set to number 5 and the text says "MasterCard". Now through code I want to set it to -1 and the text should show nothing. How can I do this?

I have a datagridview bound to a datatable setting its datasource property to the datatable. I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)
now I would like save these visible columns on some event like form_closing so that the next time the user opens the form up it will remember the settings

I am trying to create a simple Word doc that when the user presses the button it takes the information in the boxes and tosses it into a template style paragraph. But my issue is that I have two combo list boxes as seen in the picture. I want to have two values in the drop down list as seen in the labels next to them but for the life of me I can't figure out how to do this in Word 2007. In Visual Studio this is much easier but I am work and need to snap this out for the folks at work. Is there an option that I can choose in the properties where I type in the values for each drop down or do I have to add them in at run time?

I have this code that use to sort a datatable.
Dim sortingIndex As Integer = orderby
Dim DataTableNew As DataTable = New DataTable
DataTableNew = dt.Clone
Dim query = (From c In dt.AsEnumerable Order By c.Field(Of String)(sortingIndex) Ascending)
query.CopyToDataTable(DataTableNew, LoadOption.OverwriteChanges)
My problem is that with this method I always need (Of String) for it to work, so the date columns are also managed as Strings witch is the problem. Is there a way to use the correct type so the sorting is based on the type of the column?

I have an SQL Database which has some end dates. I have used this little statement to make sure that the dates come out of the database in the right format
Execute("Set dateformat dmy")
And I use the below statement to enter the data in to a datatable and, with the above command, when I go to look at the data in datatable visualiser the dates seem to be in the correct dd/MM/yyyy format
"SELECT CID, expdate FROM Traineecerts WHERE iscurrent = 1"
Now when i try d1 = row("expdate") the format changes to the american MM/dd/yyyy format
Please note d1 refers to a variable with the type of date. Even if I format the dates after using d1 = format(row("expdate"),"dd/MM/yyyy") they don't change unless I make d1 a string. Is this normal?

I have a session which contains a datatable and also have a function which returns a datatable. I need to add these two. How can I do this? The below code is to be replaced with correct code.
Session("Table")=Session("Table")+obj.GetCustomer() where obj is an object of the business layer.
The '+' sign cannot be used to add these two, so how can I do this?

I am writing a school project in VB2005 and am trying to hook up a second combo box that gets its information of what to display from the first combo box. My application is where a student takes a "test" but they can choose what instructor they want in the first combo box. From there, they choose from a test of what each instructor offers in the second combo box. As of right now, my first combo box works great and my second combo box has nothing in it. Just a note, when I debug, it shows my iUserID value as 0.

Trying to set a Combo Box RowSource to a field in a table that contains the choices separated by semi colons. Have tried both a query and a DLookup but it results in displaying the full contents of the table field, e.g. "10;12;14;16" rather than giving me the usual selection list

In an attempt to learn VB I'm trying to build a database project for a friend's business. This db will be used to track customer information, predominantly for targeted marketing purposes. So far, the development has been slow (I'm still trying to adapt from VBA to VB), but its all starting to make sense now. I'm using two different forms for adding new customers and reviewing the information of existing customers, mainly because the database will grow by about 2,500 customers per year and we wanted to be able to search the records without returning every record when the forms load. Most of this works so far, but I'm having trouble with two issues.
When I open the new customer entry form, I want the form to automatically begin entering data without clicking the "Add New" button. The second problem involves the row ID from the database. It keep showing up as "-1", "-2" etc. The row ID records properly in the table, so no big deal. I have read that this problem is a bug in VB and that its nothing to worry about. However, down the road I will need to access the correct row ID from this same form in order to print out a report for the customer (as needed).
For what its worth here is the code I have so far:
Code:
'Update current record when the form closes
Private Sub frmNewCustomer_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Me.TblCustomersBindingSource.EndEdit()
Me.TblCustomersTableAdapter.Update(Me.dsNewCustomer.tblCustomers)

I have a form that displays a graph. From the appropriate toobar button click frmGraph.show is called and it works. But when I call it from the assigned F6 function key the graph hardly ever displays. Sometimes it does display properly, sometime it flickers a one time display of the graph then it's gone, but mostly the form just draws the background but no graph. In debugging this i discoverd that putting a message box just before the call to frmGraph.show the graph will display properly everytime after i click ok in the messagebox. Anyone know how to cure this or at least a workaround that doesn't involve displaying the messagebox? This is the code with the messagebox("here") just above the call.
