VS 2008 ListView - How To Find Out Data Row Height
Mar 21, 2010
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.
How can I resize the height of the listview when the user maximizes the form. I used custom controls and it does not work properly with the anchor property. Do any of you had an alternative code that acts just like the anchor property? I will also place buttons below the listview and I would want them to to automatically always stay below the listview.
My application uses a ListView control to display some data from a database, and I would like to make the height of the row bigger (it is in the 'Detail' view).As you can see the rows are quite slim and rather ugly :P And I can't find a way to change the height of them in the properties for the ListView.[code]Which I can imagine working in .NET (even though it's C#) but it is obviously very very hacky.
I want to draw a string at a specified location with a specified width. If the string is wider then the specified width, the string is "word wrapped". How can I find out how much vertical space was used (the height of the "word wrapped" string)?
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 am needing to get the browser height and width of the browser window with vb. I can get these values by setting an ASP.Net hidden input control using javascript, after the page has loaded and a post back is done. I need to be able to get these values when the page initially loads so I can create an image based on those values.
Have a populated listview with check boxes. If the item is checked I want to send it to report for printing. This code is bypassed:
Code: Private Sub GetSelectedItems() If Not Me.ListView1.SelectedItems.Count = 0 Then
[code]....
Count is always = 0. This seems to work only if the item is double clicked. And then only one item is returned in the msgbox. MSDN says "The SelectedItems property will not contain any items if the property is accessed before the ListView handle is created, which typically occurs when ListView is initially loaded for display in the form. You can check to see if the handle is created with the IsHandleCreated property."
When I tried to check for the handle, an error said something about overloading. So I added this:
Code: Public Overloads ReadOnly Property GetSelectdItems() Get If Not Me.ListView1.SelectedItems.Count = 0 Then
[code]....
Which does not help. How to find the items checked/create the needed handle?
Is is possible to do basic mathematical operations like addition, division etc. in XAML?For example, I want to set the height of a button to {Binding ElementName=MW,Path=Height}/2.
i have a dataset and i want to create a textbox and a button that once you click on it it will search for the word in that textbox in the dataset, for example like in sql with the "LIKE %xxxx%" format.
here is an exapample:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim dr As DataRow()
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 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.
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)
I have a treeview and text box below it... is it easy or even possible to allow a user to change the height of the treeview which will automatically change the height of the textbox so there is no gap between them?ie one gets bigger the other gets smaller etc etc
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'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 an sql search engine. I need it to find a row of data take some of the columns and paste it to some labels or textboxes.Need some help with the code got my connection, command, I am thinking on how to split the notes and the username onto two different controls or should I get two different sql statements for them ?
Private Sub btnFind_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFind.Click Dim con As New SqlConnection Dim cmd As SqlCommand = New SqlCommand("select owner, notes from orders where orderref = '" + txtReference.Text + "'", con)
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
