Matching Items In TextBox And ListView?
Dec 15, 2010
I have ListView with records (2 columns), I have also TextBox. I want when i type something in the textbox and if there is a match to select me that row of the ListView and if there isnt a match there will be MsgBox. I`ve succeeded to do it with 1st column. But if i try to use records from 2nd column it doesnt happen anything. Here is the code for TextBox_TextChanged that is working with 1 column records.
Dim boolFound As Boolean
Dim i As Integer
Dim intLen As Integer
[Code].....

I have a child form which contains a list of names and information, like age, sex, etc, in a multicolumn listview that gets populated from an xml file on the form load.There is also a combobox on this form that contains different Ages and when the user selects an age in the combobox I have it so the listview clears and the data reloads then removes all the rows that don't contain the matching "age" value in the age column.This works but it's really slow since each time a user makes another choice from the Combobox the whole listview is repopulated from the xml file.[code]I was thinking about doing the Name filter about the same way except on the textbox keyup event, but I fiqured I'd work at getting this working better first since this is way too slow.I don't really know any way of filtering the listview other than deleting the entries that don't match what's in the combobox.But then I end up reloading the whole thing when another selection is made from the combobox.

Is there any way to detect the area under a form window. e.g I want to create a grid and use what's in that grid to match patterns.orIs there any way to take a screenshot of the area under a form?
I have been searching all over for something that will do this and the only thing I managed to find was [URL]..I do not however want it for this application (If I really wanted to cheat at a game I would buy the software). But this is a perfect example of the pattern matching I wish to achieve.Edit: OK scratch that... I have managed to take a csreenshot of the region under a form, now has anyone any experience in pattern matching images?

I have a combo box with a list of Coordinator IDs, one Coordinator can run many subjects. On another form I have a list box that contains a list of the subjects, and another list box that has the coordinator that teaches the subject. The positions match up, i.e if there is a match for the co-ordinator ID in the list box at position 3, I want to extract the subject list box at position 3 also. The problem is 1 coordinator can teach more than 1 subject. Basically I want to show the subjects taught by the Coordinator the user selects in the combo box. I have tried the following but have had no luck:

I hope someone can help me. I have an ATM machine connected to a server. A form takes a textBox entry as a PIN number and matches it to a card number in the same table which is the primary key. The card number is in a comboBox.Selected Item. I have used a dataset to fill the comboBox as the form loads. I have tried for days and got nowhere.

If I look at all the options for
me.ListView1.Items(index)
one of them is for Name.
So instead of coding
Me.ListView1.Items(index)
I can use
Me.ListView1.Items("Name")
But if I go into the properties of the ListView1 and look at the collection for the Items there is no place to set the Name.I can code Me.ListView1.Items(1).Name = "Name" and then I can code Me.ListView1.Items("Name")Where can you set the "Name" of the Items in a ListView?

I am trying to search through listview in VB.net 2008. It works fine with small list, but when the list is big ( around 25000 rows), if I search multiple items , it fails saying that index is not valid. Obviously what I understand is , it it tryiong to remove an index does not exist. But I am unable to figure out where exactly it is going wrong.
PS : while it is doing search through the entire listview, I am incrementing index = index+5 becasue I want the next 5 rows to be in the selection state as well.This is the code Private Sub TextBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp If (e.KeyCode = Keys.PageDown) Then

I have a ListView which might contains a lot of items, so it is virtualized and recycling items. It does not use sort. I need to refresh some value display, but when there are too many items, it is too slow to update everything, so I would like to refresh only the visible items.How could I get a list of all currently displayed items ? I tried to look into the ListView or in the ScrollViewer, but I still have no idea... the solution must NOT go throught all items to test if they can be seen, because this would be too slow.I'm not sure code or xaml would be usefull, it is just a Virtualized/Recycling ListView with its ItemSource bound to an Array.

I have a small application. When I click on a ListView row to Edit the details populated from the MS Access DB, I have the Else statement being executed all the time. Initially the code is attached behind a button named Edit. I have a Refresh button also which is clicked before the Edit button is clicked. Thus I just don't want to click on the OK button on the message box generated from the Else part. I just want to switch the Edit option between the ListView data when the ListView is item is clicked.[code]...

how to clear items from a ListView but no advice on how to clear columns from a ListView. The first time that the form is activated, coding creates and loads four columns in a ListView. On subsequent activations I want to remove those ListView columns before proceeding, otherwise I get eight columns and then twelve columns etc. There has to be a simple way of putting the ListView back to its initial state.

I have a listview with two columns of data in it. I want to capture all the items in the listview into an array. The array will have two dimensions, one for column 1 and the other dimension for column 2. I am a little lost on how to iterate over the listview items. I figure it would be a for each statement. Its also the actual call that passes the found item and sub item to the array I am struggling with.
