I'm trying to display new data at the top of a listview box with very little luck, the nearest I've come to it is using the following code, only all it's doing is overwriting what is already at the top with the new data[code]...
View 2 RepliesI have a vb-2008 program that contains a (listview) control.
View = details
AllowColumnReorder = true
Lets say the table has 3 columns (a,b,c) and 1 row of data.
a b c
1 2 3
I want the user to be able to re-arrange the columns (by dragging the column headers) before printing the contents of the table.
c a b
3 1 2
Statements like:
.. ListViewX.Columns(2).Text
.. ListViewX.Columns.Item(2).Text
.. ListViewX.Items(0).SubItems(2).ToString
Give the column-name (c) and cell-contents (3) of the origional table .. not the (3rd) column (b) of the re-arranged table.
How can i get the column-name and cell-contents of the (3rd) column of the re-arranged table?

I have 2 listviews that serve different purposes. Short question is that I need to find out how to pull specific columns from a WPF listview to add them to properties of an object.
Listview 1:Bound to a database table. A user changes a combo box in order to filter the table that the listview is bound to.
Listview 2:This listview is bound to an observable collection with 3 properties.
User action:The user selects a subset of items from Listview 1 and clicks "add". I want to add specific columns of listview 1 to the properties of an "employee" object and then added to an observable collection so they can be displayed in Listview 2.
What I have completed:The databinding of listview 1 and listview 2 work perfectly. I have an employee class with 3 properties (agent id, name, office). I created an observable collection that I will be adding the employees to - IM FINE with this part.
What I need:I need to know how to find the specific data of listview 1 in order to assign the correct pieces to the corresponding properties of the objects in my observable collection.
My attempt is really an epic fail.. I will loop through all selected items to get the data from each, but for my try I only used the first selected item:
Class windEmployee
Private Agents As New ObservableCollection(Of Employee)
Private sub AgentData()

View 3 RepliesI want to filter data on the textchange event on listview so I use dataview to filter data. Issue in the below code is, I use dataview inside for each so that it checks only one condition that is last value only it takes, I want to check value in s1 with dataview and remaining value should bind with listview. E.g.: if I type an in textbox it should list all the item values starting with an value like anandha kumar, anna etc. Suppose I keep the value anandha kumar and anna in array s1. I should list all other values expect the array values like antony etc... in listview.
protected void TextBox1_TextChanged(object sender, EventArgs e) {
dvProducts = (DataView)Session["ListViewItems"];
string serachText = EscapeLikeValue(TextBox1.Text);
string lvValues = hdRetailCustomerGroup.Value;
string trim = lvValues.Replace(" ", "");

i am currently working on an Application Manager that basically will free up my desktop of all my shortcuts by adding them to a program, or in my case, the listview object. Basically, so far i have set up a toolbar on top with a few options that will add listview objects, listview groups, remove those, and some other help and support things.
What i want to do is allow the user to add a listview object, which will be an application shortcut- they can choose the name, the icon, descriptions, whatever. (In essence, i am basically moving the desktop style of shortcuts into an application, where you can categorize and organize these shortcuts).
The questions i have are: 1. Is the listview object a good option for what i am trying to accomplish? 2. I saw that you can import imagelists, but how can i incorporate that to include icon pictures selected when a user adds an application? 3. How do you save listview data? 4. Anyone have a good strategy on how to approach this project? 5. Do i/Should i make an 'application' class that handles all the application information rather than using direct listview methods?
here is my code
Dim lvitem
Dim iCount As Integer
Dim iLoop As Integer

I'm new here, but I always exhaust myself in research before I go asking for help with my code. What I'm actually doing is porting a program I wrote in AutoIT proprietary code over to vb by hand. I've really come far and have figured out out how to read/write data to an XML file, which was the biggest challenge. I'm having a little bit of a rough spot with iterating nodelist data and then adding it to a listview in order.Here's what I have within a sub that begins to pull data from the file.
[Code]...
This adds data a row at a time, which is what I want. But look at the data I'm feeding it, node.innertext.I have to iterate the specific nodelist before I can use node.innertext. Putting .subitems.add in the iteration just results in a huge mess. I thought about using a function to return the data and then drop the function name in there, but whenever I iterate within the function it only ever returns the first item (it iterates only once even though there are more than one interations). Hopefully someone can point me in the right direction, I don't need to be spoonfed the answer.
I'm trying to transfer Data submitted into a listview xaml form to a vb form but having difficultly in doing so.
My goal is to be able to double click a "username" and it will move that data to a new form and be displayed in a user / pass text boxes.
I've added the code to my project to try and give you guru's a idea as to what i'm getting at.
This code runs at my other sample prog. but when I try to use it to my actual prog., it wont work.
