There's a thread that i'd read wherein you reply regarding on shortcut on populating a listview with databatable or dataset, but i forgot it. How did you populate a listview with datatable or dataset with just one line.
In datagridview .DataSource how about in listview ?
I want to populate a listview and leave selected records that are true
I have a DB record which is ID int, desc varchar, selected boolean.
I have tried the code below
LVProducts is a Listview and DS is a dataset
CODE:
Part 1 of what i want to do is on the Load Event of my form i want to look at an excel worksheet and populate a data table with the data found in the first two columns of the worksheet.
Essentially column 1 is Descriptions and column 2 is pricing
Part 2 of what i need to do is that when a user selects a description from the combo box it populates a text box with the appropriate pricing.
After doing some reading into this all i have seen is some threads on how to use Jet4.0 to link and grab the data but it is my understanding that Jet doesnt work with 64 bit OS.
Nonetheless I need to figure out a way to accomplish my end goal and make it as universal a solution as possible (ie. i do not want it to only run on 64 bit or 32 bit machines)
I have a procedure that populates a ListView, but it does a lot of work and it takes too much time to display all it's items (about 100-200 items). I want to use a thread to display the items as it's extracting data (real-time).

I have a very simple program which simply populates a listbox with a list of files stored in a directory.
Try
lvScripts.View = View.Details
lvScripts.Items.Clear()
lvScripts.Columns.Clear()

However, I'd like to embed these files into the application itself and open them from there rather than from looking at the directory.To this end I've added each of the files as a resource but I don't know how to populate the list view with a list of the text files in the my.resources rather than a list of the text files in the directory.
I have searched and searched but have not found code that worked for me. I need to get the data from a mysql db to my listview. I can already connect to the db, i just need the code to get the stuff from it to the listview.
View 5 RepliesI am trying to populate a multi-column listview from a file. I have gotten as far as reading the correct data from the file to an array and populating the correct columns with said data. However, sometimes the array will span multiple lines of data in the file and I need all of these matches to populate the listview but the code that I have now only populates the listview with the data from the first matching line. I have tried declaring the variables as listviewitems instead of strings, which allowed me to use listView.Items.AddRange(arr) but then all of the data appeared in the first column instead of spread across all columns like it is supposed to. At this point I am at a loss because I can only figure out how to either fill the first column with all data or fill all columns with only the first line of data. Here is the code that I have

I populate a datatable from a database. The table is sorted by the first column.
Then I add some new rows to the table. After that I sort the table with pgds.Tables(0).DefaultView.Sort = "firstcolumnname"
The new added rows are listed after the originally ordered rows and not in the right order.

View 7 RepliesI've populated my DataTable will all the results from a SQL search. Upon a button click I want to populate a combobox with all the results where a condition is met. My DataTable as a column called UserID and I want to add all results where the UserID is equal to a set value (for example 12). I can do this to add all results and I guess I could add a if statement inside this to be If Entry.Tag = 12 Then but is there a better way?

I am trying to populat a treeview with nodes that are the values of a column in a datatable. I have managed to get the correct number of nodes but the text is not displayed next to the nodes, there is just a 3 shape but the other way round and with square corners shown.
The code is below. I would like to have these parent nodes populated on the form load and then (i think this is what i have read) to be quicker i would like to then load the childnodes once a parent node has been selected, as i don't want to load the whole database on form load or when the form is refreshed.
