ASP.NET: Set ListView Data Through The Codebehind Instead Of Using The Bind() Function In The Text Attribute?
Dec 16, 2011
How do I set ListView data through the codebehind instead of using the Bind() function in the Text attribute?Right now I'm doing the following, but I'd like to have it retrieved and set in the codebehind. I'm using VB..
Is this code correct to fill this table? If not, why? Honestly, I've found several perspectives on how to do this sort of thing, some of which are linked below:

I also want to store it in a string to check a condition . And again set it wilth a new value if a condition is met. string s = HtmlCell.Attributes["class"] not working I have added runat="server" and added an id for it as well. But i guess HtmlCell.Attributes["class"] is cant be cast into a String. I want to access the value of 'class' attribute.
I am having trouble accessing a Javascript function from my code behind file. I need to do this as I am using the GoogleMaps JS API to add markers to a map based on addresses retrieved from my database. I have a function called AddMarker that takes in the address as a parameter, so I need to be able to call that from my code behind file in the page_load function.To simplify the question, how I can I call this javascript function to display an alert with a string passed from my code behind file?:
I have a page of checkboxes, I select a few of them, click submit, and go to a second page. on this page, I have a listview that is built using the checkboxes selected on the previous page. Now I'm wondering how i can add sortability to this listview.
In the past I would add CommandName='sort' CommandArgument='column' to the link on the header in the LayoutTemplate. But since my listview has it's header row outside of the listview, this doesn't seem to work. This is what I have so far:
<!-- header row (outside of listview, when I try to put it as a LayoutTemplate in listview i get an error, see below) --> <table>
[Code]....
I've tried to add a templatelayout in the listview, but that gives me an error on the line that binds the data (listview.databind() ), i'm assuming because this isn't possible.
I'm using VB 2010 Express and I want to connect it to sql server 2005 where I have db with just one table.What I want is to write code to connect to db and bind database fields to form controls like text boxes. I'm new in VB.net, and have found some code on net but when I try to load form textbox is empty. Here is full
I am trying to bind data from a text box on my form to a field in my database table. First of all I have created a DataSet, BindingSource and Table Adapter in the forms Design view, but I am having from there. Under the properties of each text box I have set the DataBindings (Text) to the field in the table under the forms instance and DataSet rather than the Projects Data Sources. I am very rusty at Visual Studio 2005 and that is all I have to work with.
I would like to populate a <p id="para1"></p> html tag from the codebehind page in VB. I need to read text from a text file that will be periodically uploaded from a user and display it on the aspx page in specific paragraphs.
I have created a few WebRequest extension methods that support cancelling. Is it possible to mark related .net framework methods as Obsolete. That will allow other developers to get warning and encourage them to use a new extension methods.
how to bind a listview to my .mdf dataset. how would i also manipulate the binding navigator that comes with datagrid view or details view when you put the fields on the form with buttons i want to add apart from the ones on the navigator itself?
see i have a form in that i have following controls
.combobox .textbox .listview
the combobox contains all the column names of listview like docid,firstname,surname etc
when the form is loaded the listview is populated with some data from the database.
is there is anyway to autopopulate the listview control based on search term entered on the textbox.i heard about the "onchange event",but i'm not sure how it works .
I have a question because in my I.O.File. I use this to save the data in the listview in a c: est.txt but the problem is that it only save one data and every time I click the save the previous data that I save is deleted and it change the new one that I save. And also when I click the remove in the listview it will also delete the data that save in the c: est.txt and the format should like this
First name | lastname | address | rae alanah new york john smith los angeles
Here the code that I did... Dim myFile As String = "C: est.txt" '//file location System.IO.File.WriteAllText(myFile, TextBox1.Text & " " & ComboBox1.Text & " " & TextBox4.Text & " " & ComboBox2.Text & " " & TextBox3.Text & " " & TextBox2.Text & " " & TextBox5.Text) Or you can also create new code base on ur understanding. This is the first time I use the I.O file or file stream in vb.net because my crystal report does not detect my database that's why I need to do this.
I'm using Visual Basic Express 2008 and I need to upload and sort two data text files (notepad) in a listview box. It doesn't have to be a listview box I chose that because it has nice options for columns. Anyway I've got the code set up to open the dialog box and allow the upload of multiple files. I've also got it set up to show separate columns, movie titles and box office amounts, titles in one file box office amount in the other. What I nee sorting the data once it's uploaded so the movie titles show in one column and the box office amounts show in another. Currently everything is showing in the left most column. I'd like to be able to represent the data seperately also so I can format the dollar amounts into currency. Here's what I've got so far:
Private Sub LoadButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoadButton.Click Dim DialogBoxResults As System.Windows.Forms.OpenFileDialog
I get an error when I try to build my project.'SSLAccessFiltercannot' be used as an attribute because it does not inherit from 'System.Attribute'. [code]
I have the following issue - I amcodinga move directoryfunction into my program. It all works fine except the resulting moved directory (the files within) appear(s) with a lock on them and they have become read only when they didn't start that way. I'd like to prevent the read only attribute from happening. Below is the code which moves the directory. I put it into a backgroundworker.
Private Sub bwMove_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs)
I want to be able for a user to click on a button and then it runs a function and then shows the results in the data list.i know i can get data and bind it through my tables
So - I have some text in an RTF control. I want the user to be able to highlight text and apply an attribute. The following code is placed into a button called BOLD and seems to work nicely:
If rtfText.SelectedText.Length > 0 Then rtfText.SelectionFont = New Font(rtfText.SelectionFont, FontStyle.Bold) End If
The code above will turn the selected text bold.
But then the user selects the Same text and with the following code placed into a button called ITALIC it removes the bold attribute and replaces it with italics.
If rtfText.SelectedText.Length > 0 Then rtfText.SelectionFont = New Font(rtfText.SelectionFont, FontStyle.Italic) End If
Since the users actions are separate - I can not know that they want BOLD and ITALIC, so how do I make sure I keep the existing attribute on the selected text (which, by the way could be part bold and part not-bold) and add italic?
Somehow I need to add the italic attribute to the selected text, not simply replace all attributes with italic.
I need to initialize the text attribute of the text box element with a property from some where else when actually I can simply do this from code but it will be much more convenient if it possible to do it like this:
<asp:TextBox runat="server" Text="<%= new ContextItem("title").Value %>" />
Unfortunately the above can't be done.. how to make it cleaner then to write it again and again in the code behind?
Like how do I make a drop down menu populate with the data from a connected database? And how can a label pop out on a form from code that has to do with a database? Last, how to add data to a database from saying "yes" to a messagebox that was coded?
I wrote small program which is reading xml data to datagridview (table). I used open file dialog and everything works fine. Now I would like to add some edit options to my program (add, delete, save). I decided to bind data and then use binding navigator?
