Selecting an Listview Item

Posted By:      Posted Date: September 21, 2010    Points: 0   Category :ASP.Net

May be I'm trying to run before I can walk, but here goes, I find coding for ASP so frustrating it's just not logical JIM!

Anyways after my rant, as I'm a huge fan of the listview control in WinForms I'm trying to get the hang of it in ASP, wth not much luck so far.

I've got several questions I hope you guys/girls can answer

I'm trying to make the listview winforms-e

Select Item then update/Delete as required

Also the following is a snippet of code I have that when your over the item you can select it which goes to another ASP page so it can be edited(when finished that is!).

listview 3.5 bind dropdownlists edit item template VB.NET


I am trying to do this with many issues of data binding doubling the amount and not setting selectedValue on dropdownlist. I have read some posts and they help but I am missing a crucial piece. My problem is that my dropdownlist is doubling the amount of records for the dropdownlist. Instead of "YES;NO;SELECT A VALUE", I am getting "YES;NO;SELECT A VALUE;YES;NO;YES;NO". My database is correct with the UPDATE part but the rebind after update is failing horribly.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If IsPostBack Then
            If Session("ACTIVETAB").ToString() = Session("SUBCONTRACTSATABNO").ToString() Then
            End If
        End If
    End Sub

    Public Function loadlookups(ByVal id As String, ByVal e As System.Web.UI.WebControls.ListViewItemEventArgs) As DataTable
        Select Case id
            Case "ddlCertReceived"
                dt = GetLookupTable("SubcontractsA", "Sub 1 Cert Received")
                Dim ddlCertReceived As DropDownList = _
                CType(e.Item.FindControl("ddlCertReceived"), DropDownList)
                ddlCertReceived.DataSource = dt
                ddlCertReceived.DataTextField = "lup_text"

datagrid item.ItemIndex keep selecting the wrong row number

I apologize in advance for my poor english:1. I have a dropdownList within my datagrid and its already populated fine (22 rows in my datagrid)2. The select item for the 21 row is the same as the select item of the 22 row3. When trying to do selectedIndexChange for the 22 row, it didn't seem to work. The error: Dim ddl As DropDownList = CType(sender, DropDownList)Dim dgi As DataGridItem = CType(ddl.Parent.Parent, DataGridItem)Dim rowID As Integer = dgi.ItemIndex The rowID keep staying at 20 even though the selectedIndexChanged is happening in row 22( ie. rowID should be 21)Does anyone seen this problem before??

Is there a way to have more than 1 "item placeholder" in a listview to accomplish having multiple in

I need to have 3 different sections of a listview act as a repeater, but independen of each other.  Each will have identical column headings, but different datasources.  They will all share the same Heading, but each will have a different footer.  In other words, I need to have 3 different "itemPlaceholders" in one listview. Can that be done. Presently, I have a panel with three listviews nested together.  It works fine except that the formatting of them doesn't stay consistent.  Thanks    

Issue with Combobox - On selecting Item the combobox border becomes red why?

Hi, I have a combobox. <ComboBox DisplayMemberPath="Name" Name="CB" IsEnabled="{Binding ElementName=RB, Path=IsChecked}"<br/> SelectedValue="{Binding Path=Folders, Mode=TwoWay, UpdateSourceTrigger= PropertyChanged}" /> It has Selected value binding with ObservableCollection as public ObservableCollection<T> _folders; public ObservableCollection<T> Folders { get { return _folders; } set{ _folders = value; }} Combobox's IsEnabled property has binding with a Radio button checked value.

Display the item in the ComboBox inside the ListView(GridView)

I have the below code used in binding the values to the ComboBox in GridView(ListView), please help me < ListView Margin="480,51,6,14" Name="grid1" ItemsSource="{Binding UserDetail}" IsSynchronizedWithCurrentItem="True" Width="389" Grid.Column="1" > <ListView.View> <GridView> <GridViewColumn Header="UserName" Width="120" DisplayMemberBinding="{Binding Path=WindowsUser}"/> <GridViewColumn Header="Role" Width="140"> <GridViewColumn.CellTemplate> <DataTemplate> <ComboBox Name="Rolecombo" Width="120" ItemsSource="{Binding Path=UserDetail}" SelectedValue="{Binding PFR_Tbl_Role.Role}"/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> <GridViewColumn Header="Active" x:Name="column" Width="100"> <GridViewColumn.CellTemplate> <DataTemplate> <Grid Width="{Binding ElementName=column,Path=Width}"> <CheckBox IsChecked="{Binding Active}" HorizontalAlignment="Center" /> </Grid> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView>  </ListView.View> </ListView>

Load byte[] into a ListView like in a hex editor (each byte should be an item)

Hi, I am writing some sort of Hex Editor in C# .NET 3.5 WPF. My input is a binary file, which can be very large (at least 10MB). I want to benfit from WPF's UI virtualization. For that I've tried using the DataGrid or the ListView. However, those 2 have a concept of each row being an item, and the hex dump means each cell is an item. Trying to copy the byte[] to a DataTable or a new class that implements IEnumerable takes too much memory and hangs the application. Also creating many strings / TextBoxes will be very expensive. Example of an input: 37 AA B1 00 01 05 03 33 45 66 23 45 67 43 32 12 47 5A 61 70 01 05 83 99 45 45 23 25 67 43 32 12 56 34 45 67 I would like to show like this: 37 AA B1 00 01 05 03 33 45 66 23 45 67 43 32 12 47 5A 61 70 01 05 83 99 45 45 23 25 67 43 32 12 56 34 45 67 I've encountered the wrap panel (which might suit as well with Horizontal orientation) but wrap panel has no virtualization. I'm fairly new to WPF, but I've read a lot for 2 weeks in all the web... and tried a lot!!! But still, I can't seem to find a good solution to my problem. Please help :( Thanks in advance, Michal.

ListView.ItemTemplate with Button. Command doesn't execute when item is selected

I have a listview with an item template that contains a button: <ListView ItemsSource="{Binding AllProducts}"> <ListView.ItemTemplate> <DataTemplate> <Grid> <Button Content="Add Supplier" Command="{Binding AddSupplier}"/> </Grid> </DataTemplate> </ListView.ItemTemplate> </ListView> When the listitem is not selected and the button is clicked, the command executes fine. However, if the listitem is selected, the command does not execute. I have tried putting click and mouse down event handlers on the button, but the events do not fire. Is there any way to make the command execute when the listitem is selected?

Listview Item RemoveAt


Hi There,

I'm trying to delete a item from the listview.

I can delete the item from the database ok, but the listview item does not get removed, I could do a Response.Redirect to redisply the page but this is overkill?

Below is my code:

 Private Sub ListView1_ItemDeleting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewDeleteEventArgs) Handles ListView1.ItemDeleting

  Dim key As String = Me.ListView1.DataKeys(e.ItemIndex).Value.ToString()

    'Dim mDbase As New SQL40.Database.SQL.SQL(<Sever>, <Database>, "", "", True)
    ' mDbase.Open()
    ' mDbase.Record.Delete("DELETE FROM TBLResults WHERE ID=" & key)
    ' mDbase.Close()
 End Sub


ListView, DataPager, LinqDataSource: LinqDataSource Selecting event fire twice


Dear all,

In my web app, I used LinqDataSource, ListView and DataPager (.NET 3.5 sp1) to implement search feature with paging. I have a button to trigger the search.

But In the first time, the Selecting event of LinqDataSource fire twice and I don't know why (I debugged my code very carefully). I don't use QueryString with DataPager and assign PageSize of DataPager in the first time of page load to prevent the ListView bind again (as in some instructions I found in forum)

Have anyone seen this problem before? And If possible, can you give me some instructions to try?

I can't post my code because it's quite large.

Thank you very much
