I want to be able to get the current bound object in the ItemTemplate of a ListView control.
Here's an example of what I want to do:
<asp:ListView ID="UserList" runat="server">
<LayoutTemplate>
<asp:PlaceHolder ID="itemPlaceHolder" runat="server" />
</LayoutTemplate>
<ItemTemplate>
//How can I get the current bound object in here?
</ItemTemplate>
</asp:ListView>
I have ListView control on my page, and i bound it to Dictionary<string,DataTable> generic.Now i'm trying to put DataPager on my page to support paging, but DataPager doesn't work properly, in particular, I have to click twice to move to next page, or first few records repeating thru every page. What's the problem, what am I doing wrong? I used ListView control before with ObjectDataSource and it worked just fine. Now I'm using Entity Framework to retrieve data frm Db.

View 3 RepliesI need to change the row.forecolor = drawing.color.red.
in my gridview i have a STATUS field, its ItemTemplate is LABEL1 and its EditTemplate is DropDownList1.
on loading I have successfully changed the forecolor, but when I edit it gave me an error:
Object reference not set to an instance of an object.
I have various difficulties handling dropdownlist in listview itemtemplate.Hopefully, resolving this example will help me understand how to make things work.I need to do several things upon DropDownList1_SelectedIndexChanged.(1) Fetch row index of listview then set the row as listview selected, or vice versa, in which dropdownlist was changed.(2) Fetch text of namelabel in that selected listview row.(3) Fetch selected text of dropdownlist in that selected listview row.
[Code]....
At the moment...(1) Label1.Text = ListView1.SelectedIndex always shows '-1' regardless in which row dropdownlist is selected/changed.(2) Label2.Text = NL.Text pops 'Object reference not set to an instance of an object'.(3) Label3.Text = DDL1.SelectedItem.Text pops 'Object reference not set to an instance of an object'.

I am using a ListView and would like to implement the switch from read only mode to edit mode for a ListView item on the client side. Some of this is discussed at: Inline form editing on client side
I am trying to do this by something like:
[Code]....
switchState is a Javascript function that simply hides/shows the DIVs with the readonly and edit classnames. In LinkButtonSave_Click I get the value from TexBoxName but it always contains the bound original value and not the edited value that was entered in the texbox.
Does ASP.NET not postback the textbox value because it is in the ItemTemplate or is it something else that's causing this problem? Could I use a Repeater instead to accomplish this?
I was wondering if there is a way to hide the ItemTemplate. I am using listview and would like to hide the itemtemplate when i am inserting a new record. Im not sure how to or if it is possible to do.
View 4 RepliesGiven the following code for a textbox in the EditItemTemplate of ListView:
TextBox txt = (TextBox)ListView.EditItem.FindControl("ImageURLTextBox");
How would we code for a textbox in the ItemTemplate of the same ListView?
The following code represents an EditItemTemplate in my ListView. My problem is that when I click the Update button, everything updates but then the display doesn't go to the ItemTemplate. According to Microsoft: "By default, theListView control returns to read-only mode after an update operation."
[Code]....
I have listview where every item has a textbox and next to it a button if you want to update the item. I want that every textbox default button(pressing enter) is the one right next to it. So i have a panel(pnlInput) surrounding the textbox(txtQuantity) and the button (btnCart). If i do nothing in code behind the default button for every textbox is the button of the item that was first rendered.
But then i tried in codebehind
lstArticles_ItemDataBound
//Set default button right
Panel tmpPanel = (Panel)e.Item.FindControl("pnlInput");
Button tmpButton = (Button)e.Item.FindControl("btnCart");
tmpPanel.DefaultButton = tmpButton.ClientID;
But when i tried that i get the execption when the page is rendered that the default button for a panel needs to be of type ibuttoncontrol. I also tried UniqueID, but the same happens.
on SelectedIndexChanged event handling of DropDownList in ItemTemplate of ListView. I put OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" in mark up, with code behind, but only to get Compiler Error Message: BC30456: 'DropDownList1_SelectedIndexChanged' is not a member of 'ASP.webform1_aspx'. How do I make it a member? When I do not put OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" in mark up, BC30456 does not pop up, but nothing happens when dropdownlist selected item is changed.

I've got the following ListView (extra code removed for clarity) :
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<ItemTemplate>
<asp:Label ID="lblHomePhone" runat="server" Text='<%# Eval("HomePhone", "{0:(###) ###-####}") %>' ToolTip="Home" />
</ItemTemplate>
</asp:ListView>
This does render the phone number, but it is unformatted (8005551212 instead of (800) 555-1212).Why is the formatting not applied?

View 4 RepliesThis is a weird issue. I have a List view with 2 Link buttons. "Edit" and "Delete" Iam able to attach an event handler for the first linkbutton(Update). Code in the event handler executed fine. But If I try to attach a event handler for the second link button(Delete) , I get an error.
My Item Template Looks like this.
[Code]....
First Item works absolutely fine. But If I attach the second handler, I get the following error
Am I missing some thing ? Note - There is no error if I try to attach the 1st event handler to the second link button.[ie EditLinkButtonClicked to DeleteLinkButtonClicked ] Issue occurs only when I try to attach DeleteLinkButtonClicked to DeleteLinkButton

Based on the selection of SchoolID in listviewSchools, the ListviewStudents will be filled with the data.
SchoolIDLabel is in the ItemTemplate of the ListviewSchools. The following works for insertitemtemplate
Dim txtTitle As TextBox = CType(ListView1.InsertItem.FindControl("txtTitle"), TextBox), but i can not Access a control inside the ItemTemplate of a listview.
I am new to Repeater and DataBinding
In PageLoad, I have
var photos = from p in MyDataContext.Photos
select new {
p,
Url = p.GetImageUrl()
};
repeater1.DataSource = photos;
repeater1.DataBind();
In the Repeater control, I have
<ItemTemplate>
<% Photo p = (Photo) Eval("p"); %> <!-- Apparently I can't do this -->
...
<asp:TextBox runat="server" ID="txtTime" Text='<%= p.Time == null ? "" : ((DateTime)p.Time).ToString("dd/MM/yyyy HH:mm:ss") %>' />
...
</ItemTemplate>
But that is wrong.
What I need is to get the Photo object in ItemTemplate so I can do things with it (eg. to display the time as in the second line in ItemTemplate above). Is it even possible to do this in a Repeater?
I have a listview showing the data, and that i will use to Show, Edit, Delete, and Insert data.

Neither updating data or turning back to ItemTemplate.
Here is its code:

I figured this wouldn't be too difficult to do, but I can't seem to figure out how to do it. Is there a way to easily access the current item from a ListView data source? For instance, you can easily evaluate the current item's properties using Eval("propertyName"), but is there a way to access the object itself?
And if this isn't possible, what I ultimately want to do is get the Type of the object.
i have a listview (table layout) bind to a sqldatasource (sqlprocedure) with a datapager for custom paging and custom sorting using linkbuttons.
The problem is, if i click on a linkbutton to sort, the datapager jumps always to the first page.
Is there any way to keep the current page on sorting?
I tried DataPager.SetPageProperties() on sorting event, but it doesn't work.
