I have a list box with over 50 words. I would like the user to be able to type the first few letters of the word in a text box, and the program would automatically set the SelectedIndex property to that word in the box.
View 2 RepliesFirst of all, I'm a somewhat-experienced VB3 Developer, and I'm trying to convert a VB3 app to VB.NET.I got the programming guide (http:url....) by searching the web.The problem I'm having is the syntax for .NET is way different than VB3, and that's OK, but finding the correct syntax is very difficult.I'm trying to eliminate duplicates in a ListBox:
When I access the Programing guide, I see that:
ListBox.SelectedIndex Property
Gets or sets the zero-based index of the currently selected item in a ListBox.I also have Murach's and Stephen's manuals, and they say the same thing.Visual Studio converted The old .ListIndex to a VB6 Function:
If VB6.GetItemString(PlayList_ListBox, I) = VB6.GetItemString(PlayList_ListBox, I + 1) Then
This is Try #1. It generates: VB6 is not declared. It may be inaccessible due to its protection level.Then I read that VB6 is only for converting old code.So then I tried SelectedIndex:
Dim I As Short [code]..........

View 10 RepliesI have a dropdown list that I am binding to a datatable. Here is the code I am using to do it:[code].....
Unfortunately, the line ddlBuildAddr.SelectedIndex = addressId is failing. Looking at this line through the debugger, the SelectedIndex goes to -1, while addressId goes to 2. What gives? Why would the assignment operator flatout not work?
Is this possible? I programatically change the selected index when a certain event is fired using this code:
DropDownList.SelectedIndex = DropDownList.SelectedIndex + 1
Now I want to update a corresponding textbox with the text that is in the new SelectedIndex of the DropDownList via postback.What's the easiest way to do this?I know how I can do this in javascript.... I was just wondering if i could do this in the VB code behind.
I click on items in my listbox and then hit a submit button, but when istep through my button_clicked code it doesn't detect any selectedindex. All controls are in the same form and there are no panels. Why can't I detect what items were clicked on in the listbox?
View 2 RepliesMy 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?
