Forms Data Controls :: Binding Datatable To Listview
Apr 22, 2010I have a function that constructs a datatable from a file that the client uploads. And I want to bind that datatable to a listview but I'm not sure what I'm doing wrong... Say, the datatable is like:
FirstName LastName
John Smith
Here's how my aspx looks like:
[Code]....
In my names.aspx.cs file, I do: lvNames.Datasource = dt; //dt is a datatable
lvNames.DataBind();
When I run my aspx page, the listview is empty, is there something obvious I'm doing wrong?

View 1 RepliesForms Data Controls :: Changing The Items In The Listview At Runtime?
Feb 2, 2010There is a page in my project named Messages.aspx that shows the messages received [but obviously], using the ListView control.
I want that the user should be able to see the body of the message on the same page [Messages.aspx] just by clicking the subject of the message, which is ofcourse a link.[Messages.aspx?msg_id=some_id]. Hence the user would actually reload the same page to read the contents of the message.
Now what I want is that I should be able to write some code that would change the <LayoutTemplate> and the <ItemTemplate> of the listview during the runtime. [in the page_load event of course]
Previously the listview would look like this:
[Code]....
After the clicks any message to read it and the page gets loaded, I want the layout of the listview to look like this.

Forms Data Controls :: Multi Selecting Items In A Listview?
Jul 18, 2010i have the following problem. i'd like to use a listview with paging for mulitple selection of items in a list. The selection is no problem. I do have f.i. a list which holds the key values.

Forms Data Controls :: ListView With Datasource And Later Adding Items Dynamically?
Dec 11, 2010I have a listview which has a complicated Item template that contains a repeater, an objectdatasource and some other controls. On the first run I am only showing 10 Items of the listview. The user has an option to show 10 more ListView Items. If user clicks on show older items; the listview shall add another 10 items. how to go around this since my list view already has a datasource and I don't want to rebind the whole listview all over again. Instead; I just want to add another 10 items.
View 7 RepliesForms Data Controls :: VB - Manipulating Data Items In Code Behind And Adding To Listview
Feb 10, 2011i'm currently learning .Net and i can get data out of a database and display in a listview. But how can i access data items in the code behind and format, change, concatenate...do whatever i want to them then display in the list view? Is it even possible?
[Code]....
Maybe an example of what i'm trying to do would be to concatenate a address from the dataset and in a variable sAddress and then attach sAddress to a label in the list view, or add to colums of the dataset together and then show in a label in the listview.

Forms Data Controls :: Listview Not Reading Info From Databound Items On Update
Mar 14, 2011have an annoying problem. i'm trying to update single items in a databound listview. but when i click the update button it gives me the cannot insert NULL value. it doesnt seem to read anything from the textboxes which i have databound from the database. even though text is clearly shown...
i have setup my update statement and parameters, it uses the Update command name and ItemUpdating event. i catch the data from the textboxes by using e.ItemIndex and use the text assigned to the parameters in a SqlCommand.
The thing i'm aiming for too is that when an item is updated it stays on the page where the item was updated, (i was using response.redirect before but it went against my aim since the whole page reloaded)

Data Controls :: Populate ListView With DataTable
Nov 22, 2015This is what i want to do with my website. I want to pull data from an access query and and load it into a listview table. The user will sort through the data on the website and remove the rows she doesn't want. After the user is done, they will click a send button that will email the data to the appropriate party.I have read the access query data into a data table. I have the list view table built, but I am unsure how bind the data table into the listview table. Is this the best route to go? Will binding the datatable to the listview table allow the user to delete rows out of the datatable?
Protected Sub btnView_Click(sender As Object, e As System.EventArgs) Handles btnView.Click

Feb 2, 2010I'm displaying a bunch of items in a ListView. Each item has a button that the user can click if he/she is not interested in the item. What I want to do is this: if the user clicks the button, I want to remove that item from the list but I don't want to necessarily make a datadabase trip for each and every item the user clicks. I'd rather make one DB trip and take care of all the items user has clicked. However, as the user clicks them, I'd like to remove them from the ListView.

Forms Data Controls :: Gridview Copying Data From One Field To Another When Updating
Mar 5, 2010I have a gridview based on a sqldatasource that has some colums from which two colums showing the data of two fields: field1 and field2. field1 is an ID which should not be updated and therefore it is readonly=true. The sql-query from the sqldatasource is:
SelectCommand="SELECT field1, field2 from anyView"
What I want is, that when a row is updated, then the value from field1 should be copied to field2 The update-query is:
UpdateCommand="UPDATE myTable SET field2=@field2 WHERE field1=@field1"
My idea was, that the @field2 paramter gets the value from the query string out of field1:
<UpdateParameters>
<asp:QueryStringParameter Name="field2" QueryStringField="field1" Type="Int32" />
</UpdateParameters>
But this does not work. Is there an easy way to copy the data from field1 to field2 when updating the row? In addition, is this possible, even if field2 ist not shown in the gridview (i.e. field2 is selected in the query but is not a field in the gridview but should be updated with value of field1).
