I am going crazy trying to figure this one out. I have been told many times that you can get the data of a column in a listview in this manner: YourListView.SelectedItems(0).SubItems(1).text This does not work. I have a ListView called EmployeeListView that is correctly populated by my database. There are three columns: (0) is First name, (1) is Last name and (2) is Employee ID. I can see the information in the ListView when I run the program. What I need to do is to pull out the Employee ID and put that into a variable called EmpID.
I've been searching and searching, but I haven't been able to find a halfway-decent way of adding multiple columns of data into a WPF VB.NET ListView. The data I'm adding is not from a datasource. [code]...
I am making one program, it goes like: I put some data in textbox and when I press the button it goes to listview this part is no problem, but I don't know how to sum data what is entered in listview column nr 4 when I press some button and display the result in one other textbox or label.
i am developing a point of sales system. currently i have my product code scanned and displayed in a listview. lets say that i have 5 product codes displayed in my first listview. By clicking on a button, how can i use these codes to call upon the details (prices, product name, etc.) of the corresponding codes and display in another listview?
i am using Visual Basic 2008 and MsAccess as my database. who have the idea on solving my question. (As my last thread has not been answered at all..
I've a ListView with 5 columns and the CheckBoxes property is set to true, Now how do i make the Checkboxes on any other column rather then the 1St column? Also i would like to change the state picture of the checkbox to something else when it's checked and unchecked.
How would I change the text in the last column in the listview. I was thinking of looping around the lsitview but that would just change ever item. Anyways this is what I have.[code]
I have a 3 column listview. Column 1 and 2 has few integer. How can I subtract Column 1 and column and show the result in column 3. Below is a sample data for columns.
Is it possible to have a checkbox in a column header when in "Details" view? I want to be able to select all items in the ListView control with 1 click. Or is there another way to add a Select All command?
I have a ListView in which the items in the first column are selectable with a mouse click. How to I make these items non-selectable?FWIW, I've dug into the properties for the ListView but not been able to find which parameter is the right one to change.
I have a listview control in my form which contains 44 columns. When user clicks on particular node in the 'tree view' it loads corresponding records to the listview. If the number of records is less then it works fine, but if there is more number of records then it takes more time to load(very slow).
I am having some trouble accessing the data in a listview. The data in my listview is popluated from the database which works fine. What I want is the user to be able to click on the entry in the listview and it show them a messagebox with all the data from the listview. I have 1 main item and 2 subitems in the listview.
I'm trying to build an app using WPF and I want to display a load of data from some tab delimited log files in a data grid style. I know there is no DGV control for WPF so after watching a few "forms over data" videos on the MSDN site I figured I should be able to do it using a ListView with DataGrid tags within it.So after messing about with the XAML code for a bit I managed to create my column headers in my ListView etc and I can load data into it fine if there's just one column... but obviously I need more than one column.
So I thought fine I just create my extra columns and then use ListViewItem and ListViewSubItem classes to create the content for the listview and then add them to it. However, it seems that ListViewSubItem does not even exist in WPF and the ListViewItem doesnt seem to have any way of editing separate column data. For example, if I set ListViewItem.Content = "some text" and then add that to the ListView it just sets "Some text" in all 5 of the columns I have.All of the examples on MSDN are using data bound listviews and I dont want mine to be data bound I just want to manually load it with items.
I'm connected to an access database using VB 2008.. there is information already located in the tables. But what I am looking to do, is find the "SUM" of all the data in a certain column.
My task for the moment is just to find out what the height of ListView's data row is (not the header--different height). The height of a ListView meant to fit exactly the contents of the list can't be set statically. This is because, when a system uses font scaling, the ListView rows are going to be scaled relative to the scaled font. So, I have to find out what the height of the first row is (since they're all the same height) and then multiply that by the number of items in the list. This should get me an exact fit for the height of the ListView.
if this question has already been answered many times, but I am new to VB and I don't really understand any of the examples I have found by trying to research this topic. I am using VB 2008 Express Edition. My List View is called listView.
why my code isn't deleting the selected row in my ListView from my SQL table? it says it works fine in run time and removes the seleced row from the ListView but when i restart the program its there again.
Obviously this is because my code isnt actually deleting the data from the SQL table but i cant work out why not? the code for my delete button is as follows
Private Sub btnDeleteTask_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDeleteTask.Click Dim delete As DialogResult = MessageBox.Show("Are you sure you want to delete this customer?", "Delete Customer", MessageBoxButtons.YesNo, MessageBoxIcon.Warning)
rewriting a class I use for saving Treeview data to a XML file for use of saving ListView data I can't really figure out the rewrite, I'm stucked, unfortunately Listviews seems to be a big problem for me in general.
Option Strict On
''' <summary> ''' The TreeViewDataAccess class allows the nodes within a TreeView to be ''' persisted to xml for later retrevial. ''' </summary>
I have this test form where I'm testing the idea, but ran into a snag. Now the main idea is to load all the data from a dataset into the one column of the datagridview. This works perfectly as shown in the image. Now there is something that I want to happen, but just can't get it right. when on the DataGridViewComboBox Column I also want to be able to type in my own data if the one I want is not available in the combobox.
Also if there are 50 values in my combobox and 2 of them are: jacky, jacson When I type jac, I want the combobox to only give me the options starting with "jac"
Here is the code that I'm currently using: Dim dt As DataTable Dim dsNewDataset As New DataSet() Dim i = 0, intSetArray As Integer = 0 Public Function JT_PullDataWithCOLUMNS1(ByVal Cols As String, ByVal TableName As String) As DataTable [Code] .....
i need to use virtual mode in a listview to load data from a table...what to add in the retrievevirtualitem event... i have a data bindingsource which is attached to the table..
I have a program that is reading and writing to certain memory addresses to a particular application exe...
So I have a listview control with 4 columns and X rows
| Name | Address | Type | Value |
Name: Is just an identifier so the user knows what it is.Address: Is a specific memory address (eg 0058AFA0).Type: Type of value stored in the address (eg, 4 Bytes, Float).Value: Value to store in the address.Im looking for a way to go through each row, take the address and use this to read the value at that address and then update the value on that row
I'm somewhat of a novice at VB.I have a DataGrid that I am manually populating from a SQL query-based dataset (see code below). Question: How do a capture the value of a specific column of the selected row (mouse click in the row) to use as a variable in other parts of the overall solution?Also, how do I add cell padding around the contents of the data grid cells?
