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"

Bind GetAllUsers To ListView with ItemDataBound

Hello all, I am using a listview to which I want to bind the MembershipUserCollection which you get from GetAllUsers(). I don't want to use reflection, I want to assign it in the ItemDataBound event of my listview. I've done this before, but with datatables. The code will be something like DataRow dr = (e.item.DataItem as DataRowView).Row. You can then access specific columns with dr["ColumnNamehere"].ToString(). But how do you do this with MembershipUserCollection?

Bind a ListView to a return value from a method

I have a ListView in my View that I would like to bind to the return value of a method on my ViewModel.

Bind .NET ListVIew to Sharpoint list with Eval


I have a rather basic question of something that I just can't get to work. I have a user control with a ListView control. In the code-behind for the user control I bind the control to a SharePoint list.

Now, I want to render the items in a certain way in the LayoutTemplate and ItemTemplate sections of the ListView. I try to do this by binding to the columns with Eval, but this binding never returns any data work... 


This is some of the ascx:

Using ASP.NET 3.5's ListView and DataPager Controls: Displaying Data with the ListView

Prior to ASP.NET 3.5, developers who needed to display a set of records could choose between the GridView, DataList, and Repeater controls. The GridView provides rich data features, but has a very boxy layout; the DataList and Repeater allow for a more flexible layout, but lack the "point and click" data features found in the GridView, DetailsView, and FormView controls. The ListView bridges the gap between layout flexibility and built-in data features.

This article, the first in a series of articles on the ListView and DataPager controls, looks at the ListView's many available templates and illustrates how to display data. Read on to learn more!

WPF Tutorial - Using The ListView, Part 1

Many of the controls in WPF have a downright dizzying array of capabilities and features, due in large part to the composibility of all the components. The ListView control is a great example of this - the possibilities are almost endless. This series of tutorials on the ListView will hopefully make the space of possible options seem not quite as daunting

How to bind GridView and DropDownList controls using DataTable object

In .net framework 2.0, you can load a DataTable in memory by consuming a data source using a DataReader. In this version you will find the flexibility in accessing the DataReader means write access code once and use again and again using DataReader.

How to listen to events within a listview



I've got a listview and I've put a button control in one of the columns, I'm trying to figure out how I have listen to the button click within a certain row, but can't see the button in the dropdown for the IDs I can generate events for.

I'd like to get the primary key of the row that's been clicked on and then run a sql statement against it.

Any help would be appreciated.

ListView DataPager with SQL-Statements that already return only paged data.



As far as I understand the ListView-Control and the DataPager-Control, they work like this: The ListView gets its datarows from its data source, then the DataPager causes the ListView to display only a subset of those rows.

So what, when I want to use custom databinding for the ListView, that *already* gets the certain subset from SQL-Server (for better performance). Can I and how can I use the DataPager then?

Thanx, S.

.NET Reflection: Dynamically Bind Your Data Layer to Stored Procedures and SQL Commands Using .NET M


One major inconvenience of using SQL stored procedures from code is having to match type information. You have to write long wrapper functions around the procedures just to expose the data types. In the .NET Framework, however, the reflection services of the System.Reflection namespace allow you to query rich metadata that describe data types. This article explains how to use reflection in .NET to end your stored procedure nightmares. The author creates four custom classes, including one that generates a SQLCommand object based on the metadata of a method. Using this library, you'll be on your way to automating the generation of stored procedures.

Programmatically Simulating the ListView's ItemCommand Event


I have a User Control that contains a ListView.  In the user control's code is this event handler:

    protected void listView1_ItemCommand(object source, ListViewCommandEventArgs e)
      Button_ClickHandler(source, e);

What's occurring is that I'm explicitly firing an event so that the parent web page can monitor this and take appropriate actions.  Thus when the user clicks on a different ListViewItem it triggers the population of associated data elsewhere on the web page.

This all works fine except for one thing: When I first load the control I'm pre-setting the first ListViewItem.  Unfortunately, just setting the ListView's SelectedIndex = 0 doesn't fire the aforementioned event handler.

So I started investigating how to call "listView1_ItemCommand" but couldn't figure out how to instantiate the "e" parameter.

Any ideas of how to resolve this?
