VS 2010 - Display Contents Of A File Selected From ListBox Into Text Box
Jul 18, 2011
I need to display the contents of a file selected from a ListBox into a text box. When I populate the ListBoxItems, I set the Text property to the name of the file and its full path to the Value property.
When I click the item, the page refreshes because AutoPostBack is on, but nothing happens. I then tried this:
VB.NET Code:
Protected Sub lbLogs_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles lbLogs.SelectedIndexChanged Me.txtServiceTag.Text = Me.lbLogs.SelectedItem.TextEnd Sub
I'm trying to read the contents of a text file into a text box on my form. When I run the following code, nothing happens.
VB.NET Code: Protected Sub lbLogs_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles lbLogs.SelectedIndexChanged For Each li As ListItem In lbLogs.Items If li.Selected Then Using sw As New StreamReader(li.Value) txtLog.Text = sw.ReadToEnd sw.Close() End Using End If Next End Sub
I populate the ListBox with ListItems and each ListItem's Value property holds the full path to the file. But, I removed all of that and just put txtLog.Text = "test" inside of the "is selected" block.
How would I retreive the following numeric id value from a xml response, to a dropdownlistbox?
[Code]....
The following does not work for newContactID
var xmlResponse = proxy.ProcessClientAction(xmlRequest);var parsedXmlResopnse = XElement.Parse(xmlResponse);
I would like to have the ContactRecID's value stored in the variable newContactID based on the selection of the user. So if the user selects the the person "Sam" then 4033 should be stored in newContactId.
i want to display value in textbox when a value is selected in listbox in webapplication vb.net.

I'm using a ListBox to display fairly long text items (500 characters). If an item is too long it will go out the side of the ListBox and not be fully displayed. How can I get items in the ListBox to wrap? Also, is it possible to put some sort of separator between each item?
I'm working on an application (ASP.NET, Webforms) that generates a list of outputs based on a user input. I want to allow the user to save the contents of said list as text file, or possibly as other filetypes such as .csv. What is the best way to approach this? Can it be done client-side with Javascript?

I'm having trouble getting selected items in a listbox to be seen as selected. On my aspx page there's a listbox and a button:
[Code]....
But if I change my condition to Not selected, the string does build, with every item in the list. So the Sub is reached, the items and their text and values are seen, but user selection of items doesn't work. What am I missing?
Im with ASP.net using VB.net. What was supposed to happen is that upon page load, the system will automatically create a folder in C:. After that, the user will browse a text file and upload it to the created folder. But what happens is that both the folder and the text file is being uploaded inside C: where it should be the folder only and then the text file should be inside the folder.Here's my code.
Code: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Directory.CreateDirectory("C:TEXTFILEFOLDER") End Sub Private Sub DeleteFile(ByVal strFileName As String)
I am trying to display selected file to a user right after he selects. Which means I have to save it to a temp location and change image src (or ImageUrl if we are talking about asp:Image).
And I am trying to use AsyncFileUpload (from Ajax Toolkit) for that. Apparently it has "OnUploadedComplete" server event, but sadly it isn't working.
