Taking The Dataset And Putting The Results In The Listview?

Mar 24, 2009

I have a form with a Listview. I have not manually added columns through the gui so I need to do this too.I have a stored procedure which returns two sets of data. One is titled url and the other occurrences in he procedure.I have bound the results to a dataset. I am having problems taking that dataset and putting the results in the listview. Here is the code I have:


It is not creating the column headers. It is not putting both results in the view. It is only putting the first column "url" It is not putting the next row on the next line, but placing it in the next column where the occurrences should be going. It is also not resizing the columns to match the data , but keeping at the size assigned (I assume) in the columns.add section.

C# - How To Convert Listview To DataTable

Jun 22, 2012

I have seen many examples of populating a listview from a datatable or converting a datatable to a listview but what I am trying to do is exactly the other way around.

How can I convert/copy the contents of a winform listview to a datatable?


I have a listview with a context menu where users can multiselect items and choose one of the context menu options, I then loop the selected items and extract each selected row (listview item) and serialize it, instead of doing this I wanted to convert the listview to a datatable then add the datatable to a dataset and serialize the dataset.

Asp.net - Extract/convert Information From A Listview (to A DataTable)?

Jan 4, 2010

I have a relatively simple Listview that suddenly needs (due to new requirements) to have it's 'layout' extracted to a DataTable so that a common routine can convert it to an Excel spreadsheet for export purposes.The ItemTemplate is just a series of Table Rows with some text, data-bound labels and textboxes with validators in the cells.Usually, when trying to pull out a particular value (like what was entered into a text box), I use the ListViewItem's .FindControl method.

For Each objItem As ListViewItem In lvwOptions.Items
Dim objTextHrsLabor As TextBox = CType(objItem.FindControl("txtHrsOptByLabor"), TextBox)
decHours = CDec(objTextHrsLabor.Text)

In this case, however, I'm trying to take all the data displayed - all the 'rows and columns' of the table that was created.Inside the ForEach / Next loop of ListViewItems, I started a ForEach/Next loop of Controls for each instance's controls but I got some really strange results returned (like controls that had a couple of table cells in them).

I get the sense I'm headed in the wrong direction. All I want is for the nicely-formatted 5-line, 6 column table to be converted to a 5-line, 6-column data table.
