• Patrick Keller BindingNavigator - Detail/DataGridView

  I am quite new in VB I am trying to make a simple form with tables from a SQL database.I have three tables ( 1 parent and 2 children) shown as details. They areralated in a dataset with primary keys and FK. I have added two sets of data into thedatabase. When I run the application it works out fine, and I can shift between the two sets of datawith the navigatorbar. The three tables shifts correctly. However - when I add a new record into the application and save it, it is only the parent table that obtains the data. The two other tables become empty when shifting away - and back to the new record. I would be very pleased if anyone can help me out of this problem. I now found out that my application works out fine when the parent ...Show All

• DRoden Display text in an ownerdrawn listview - again.

  Hello, The concept goes like this: The user selct n number of rows in a listview, and then right-click the mouse, and select an item from the popup menu. How many items - and which one - the user selected, and the text to display in the columns 1, 2 and 3, is determined in the sub shown below. So far, so good.The problem is that I can't see a way to get the text into the listview, and I don't know what triggers the DrawItem event in this case - control is Ownerdrawn. I would be grateful for some hint to point me into the right direction in this matter.

• data_architect Add entries to ComboBox in DataGridView

  The best way to ask this question is to describe the simplest scenario of what I am trying to do. So here goes. I have two business objects: 1) Address - For simplicity assume only 3 columns : ID, Street, City_ID 2) City - Columns: ID, CityName I would like to have a form where the address is in a DataGridView control and the User can get the City from a dropdown or combobox. Thats the easy part, I know how to do that. What I want to achieve is something that is easy to do in MS Access but an equally simple solution in VS2005 has been eluding me: First, if the list of Cities is empty, I don't want a gridviewcomboboxcell error. Second if a user types in a city that does not already exist, I want that city to be added dy ...Show All

• Mohan1 C# vs2005 .Net 2.0 ListView .HitTest(...) always null for ListViewItem

  Hi, I am having a problem with the ListView controls .HitTest method, to be honest I am not sure if this is a misunderstanding on my part. I am trying to provide edit controls for various fields within a ListView control by overlaying various controls (TextBoxes, ComboBoxes etc) onto the clicked Item/SubItem. I originally thought I would have to invoke HitTest from win32 to obtain details of the SubItem under the click region, however I found that the .Net 2.0 ListView impliments .HitTest() directly. It returns a ListViewHitTestInfo object, amoungst the various members of this object are .SubItem and .Item I perform the HitTest in the ListView controls MouseUp event, and it workd as expected so long as the clicked item is a ListViewSubItem ...Show All

• Anpiro String Function for repeating character string

  in VB6 we can use String Function for repeating character string of the length specified, what can be used in windows mobile or visual studio Hmm, I must be a bit dense here as I am not finding it in visual studio 2005. I am converting an embedded vb project targetted at pocket pc's to a windows mobile environment, but can't find that I am looking to do something like a=string(3,"x") result a= "xxx". Someone suggested string.padright (3,"x"), but that doesn't appear to be available in the mobile environment! The String() function is still around in VB.NET. For C#, you could use this replacement: public static string FillString ...Show All

Among the two, name should be displayed in the SListView control.
