Has anyone been succesfull databing the InsertTemplate of a ListView to an SQL datasource?
My ListView is databound to a SQLDataSource however the InsertTemplate needs to be initialized to the last entry/record on the database
So I can create a second datasource to grab the last record from the database but how do I bind it to the InsertTemplate?
I am not sure if I'm in the right forum but I try anyway.I am making a webproject where I have a database with tables Product, ProductDetails.In my pageLoad event I am retrieving the information from these tabels in two lists: productList and productDetailsList.
Now what I would like to do is to databind these lists in code behind to my ListView. I know how to do this if I only have one list but in my case i have two and in my listView i have fields whose information is in productList list and others in the productDetails list.
Is there a way to achieve this?
Here is some code where I am databinding one List to ListView:

I have the following classes (pseudocode):
Item ( int Field1 )
ItemDetail : Item (int Field2, string field3)
If I set ItemDetail as the datasource for an asp.net gridview:
grid.DataSource = new List<ItemDetail>();
grid.DataBind();
Can I use Field1 in the GridView? If so, what is the correct DataBinder syntax? The following code blows up trying to cast to an Item:
<%# DataBinder.Eval(Container.DataItem, "Field1") %>
EDIT: And I'm a moron. I had copied the gridview and was calling a RowDataBound event handler for a different grid... Sorry to have wasted everyones time, but there is some good info here regardless if anyone has the same question. In the end, the public properties of the base class are binding correctly.
Is there a way to bind RadioButtonList control inside of a ListView control that is bind to a SqlDataSource control?

how we find the listview index of row in case of item databind
View 4 RepliesI am using Asp.net 3.5, C#, Visual Studio 2008. Ok, so I admit I am being really lazy here, but I know there's got to be a way to do this.
I have 2 identical listviews - listview1 and listview2. There is a checkbox in column 1 of both listviews, and a button on the page.
I would like to copy the rows that are checked in listview1 to listview2 when the button is pressed.
I know how to do this by looping thru listview1, but how can I do it in one step using an ObjectDataSource?
i created an objectdatasource and bind DetailView to it.i want to set the objectdatasource.datasource to a object (for example Member class that is an Entity) it means that i want to show just one record to this with my custom method that is MemberModel.GetMemberByNationalID(string nationalID)

I am looking for a simple (fastest execute solutions) for generate RSS feed from user search result in ListView & ObjectDataSource?
For example; User does some search, the search result summary is display in ListView. If the user like the search result, he/she click on RSS button, then RSS feed is generate with entire current view record/table.
ObjectDataSource cannot find ProductsBLL Class(with "show only data component" unchecked)?ProductsBLL.cs is located at the root of the project.

I successfully bind ListView DataSourceID to ObjectDataSource but it binds only initially on Page_Load event.
When I want to bind another data through a Button_Click event, the new data doesn't bind.
aspx code:
[Code]....
Codebehind:
[Code]....
On Page_Load, I get result:
A1
<hr />
T1
A2
<hr />
T2
A3
<hr />
T3
When I Button1_Click, nothing happens, no error, no any more results and _airLineData is 53 records, not 3 records (A1T1 to A3T3) I want the binding to be with DataSourceID to ObjectDataSource (not through DataSource property and control.DataBind() method)
I'm having trouble managing how to call upon databind from clicking on a row over an already populated repeater that will populate data regarding the row clicked TO another repeater on the same page.
I've succeeded doing that with postback, calling a jquery click event of that row, taking the data of the specific row and passing it onto a "Querystring" and after postpack, it will be pushed into a Session which the ObjectDataSource of the secondary repeater will recognize and populate the data tables accordingly.
The problem is, I must do it without a postback or in other words purely on client side.
I have the following situation:My business class:
public class Foo
{
public String A {get;set;}
public DateTime B {get;set;}
// .. and other properties like
public String Intern {get;set;}
}
I'm binding that Item to a DetailsView in Editmode. (I bind a List containing a single object of Foo, becuase I do recall that I can only bind IEnumerable<> classes to the DetailView)The binding is done via a ObjectDataSource
i'm opening a new window and passing on to it variables in a querystring, the values are loaded into a function that is filling my dataset and then filling my Gridview. after i press the button field in my grid to delete an item, the databind doesn't show the updated grid but remains the same. i've noticed that if i navigate back and refresh i see it correctly. in FF btw no problem.

I'm doing research on framework development for my company. SInce I will be developing a framework I can not simply declaire all my control in the code in front. Receiently I've been having trouble binding the controls from my ListView to my ObjectData Source. Basicly the properties in my DataObjectTypeName are not populated when the ObjectDataSource "Update" command is thrown. I recieve no error, I just get null values. All I need is an equivalent to this statement for code-behind ...
<%# Bind("AbstractText") %>This would solve all my issues. Ofcouse I will most likely need to bind the control's ID somewhere but that is not an issue. How do I Bind a control to a property in my DataObjectTypeName from the code-behind?
I have an ObjectDataSource that I want to perform updates using a business entity i.e. Type="Object"). Since the values for the entity are within a user control, I have stored a reference to the control in Session and in the updating event, set the new instance to the value of the entity from the user contol property (which also pulls values from the form viaother properties of the control):
Protected Sub MasterDataSource_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs) Handles MasterDataSource.Updating
Dim entity As New Login()
Dim accountControl As AccountInfo = TryCast(Session("AccountCtrl"), AccountInfo)
entity = accountControl.Entity
e.InputParameters.Add("entity", entity)
End Sub
And here's the markup for the datasource:
<asp:ObjectDataSource ID="MasterDataSource" runat="server" EnableCaching="true" CacheDuration="10"
SelectMethod="SelectAll" UpdateMethod="Update" TypeName="Data.DAL.LoginDAL">
</asp:ObjectDataSource>
My question is, how can I get the update method to pass this entity to the update method in my BLL class? It seems the Update method requires an ID or reference to the original object to use in determining whether any changes have taken place, but I don't really want to do this. In other words, I just want to use the Update event on my ObjectDataSource to pass my entity to the method ("Update") I set as a property and then let this business method handle the update of the data. Shown below, is the BLL update method I want to call:
Public Overloads Function Update(ByVal entity As Login)
If entity Is Nothing Then
Throw New ArgumentNullException("entity")
End If
MyBase.Update("UpdateLogin", entity.Username, entity.Password, entity.FirstName, entity.LastName, entity.Role, entity.Region, _
entity.Email, entity.Title, entity.TierID, entity.Street, entity.City, entity.State, entity.Zip, entity.Mobile, entity.Phone, entity.Fax)
End Function
When I try to call this as it stands now, I get an error: ObjectDataSource 'MasterDataSource' could not find a non-generic method 'Update' that has parameters: ID, entity. Previously, I'd set up a long list of parameters of basic data types (string, int, boolean), but this is rather cumbersome and I was hoping to use an entity for this (FYI, I also got the same type of error when I tried this approach, but with the ID as the
last parameter in the list). Perhaps what I'm doing here is atypical to how the ODS is normally used?? Has anyone done something like this successfully?
I am really having a hard time trying to write something from scratch I created a 'Person' Class.Public Class Person
Private _FirstName As String = ""
Private _LastName As String = ""

FirstName = FirstName
_LastName = LastName
_Age = Age

I have a ListView, I've setup to use an ObjectDataSource, I've created my Layout and Item templates, and I'm able pull and view a list of my data no problem. However I want to add delete capabilities to my
ListView and my reference material tells me to go into the "Configure ListView..." option under the ListView's smart tag, the only problem is I don't have that option, the only three options in my smart tag are "Choose DataSource", "Configure DataSource..." and "Refresh Schema", what am I doing wrong?
