I've implemented a ListView to display selected data from a DataTable. My listview is one row high and 4 columns wide. I've setup a DataPager to the left of it and another to the right to allow the user to access any item in the ListView.My problem is simple: When the user adds a new item to the DataTable, I rebind the data again { e.g. listView1.DataBind() }, and then I proceed to select that newly added item. BUT no matter what I try, nothing works! More precisely, I do this: listView1.SelectedIndex = #; where "#" is the appropriate index number.

View 3 RepliesI have a listveiw populated from a List<> in the code behind using the following code:

The page displays the images from the list<> and button ok but nothing happens when i click it other than postback. Furthermore even when i set up a test button wich changes the ListView.selectedindex the ListView.SelectedIndexChanged event never fires even though i can read the selected index and see that it has changed.
I'm guessing that it's something to do with using a list<> from the code behind to populate the listview but i must confess to being completely clueless.

I have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.
The InsertItem Template is in the first position, making it easy to insert a new record.
And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.
I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
which works fine also.
The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:
Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub
This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.
Here is the code for a typical entry of the InsertItem Template:
[code]....
All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"
How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?

I have 4 buttons on a page. Each button opens a modal window and let's the user input data in a form. When the user hits the save button in the modal, a ListView appears on the page with the submitted data.
The button the user clicked to open the modal window is set to visible=false, so it's gone when the row is added to the ListView. Now there are 3 buttons and the same goes for those; when the user hits a button, a modal appears, and when the modal form is submitted, the button disappears and a row is added to the ListView.
In the ListView row, there is a delete button. When this button is clicked, the row is deleted and the button that was initially clicked to add this row (and open the modal), SHOULD reappear, but it doesn't. The row disappears, but I have to refresh the page before the button comes back. There is a ScriptManager on the masterpage, so I guess this is an AJAX partial refresh issue. I tried adding different events, but I can't find the one that fires at the right time.
I use an ObjectDataSource to fill the ListView, and the data comes from a database, wrapped in a business object.This code loads a business object in a List<> and checks if the user inserted an item of a specific type. If he did, the button he used to open the modal is hidden. This works fine (maybe not the most elegant)
_goals = GoalManager.GetGoalsByUser(UserID);
if (_goals != null)
{
foreach (Goal _goalinlist in _goals) [code]...
As you can see, I tried setting a boolean, and then check it when the page is re-loaded. But the problem (I guess) is that the whole page isn't refreshed when the delete button is clicked in the ListView.
This is the delete button in the ListView:
<asp:ImageButton ID="ImageButton2" runat="server" CommandName="Delete" CausesValidation="false"
ToolTip="Delete" CommandArgument='<%#Eval("GoalID")%>' ImageUrl="delete.gif"
OnClientClick="return confirm('Delete this post?');" CssClass="button"/>
I guess the question is, how do I make the button re-appear right after the ListView button is clicked?

I'm using a ListView (e.g topListView) with paged rows (using a DataPager). One of the topListView's features is when a user clicks on one of its rows, its SelectedValue property is used to populate a SelectParameter in another SQLDataSource control that populates another ListView (e.g. bottomListView). It's working fine. Even when the webpage first loads, the SelectedValue of first row of the topListView is successfully being used to generate content in the bottomListView.
However, when one of the DataPager's buttons is clicked, the SelectedValue seems to be ignored, and the bottomListView isn't refreshing. And yet, when you click a DataPager button again, it works. basically it's taking TWO clicks of the pager for the SelectedIndex to be read. I've tried assigning the SelectedIndex to 0 in the PagePropertiesChanged and PagePropertiesChanging handlers but no luck (even with calls to bottomListView.DataBind(); and/or SQLDataSource1.DataBind(); after index assignment).
assigning the index seems unecessary though, since top row content is being rendered correctly in a SelectedItemTemplate after clicking any DataPager button. to me that means the SelectedIndex is being set to 0 when the page is being re-rendered.

I have a listview control which is bound to DataTable object. When a user clicks "Add", I am creating a new row in the underlying datasource and refreshing the datatable so that it includes the new row and displaying the listview. My requirement is to "select" the newly added row after listview is refreshed. I have the ID of the newly created row and it is bound as one of the columns in the datatable.Now my question is, how can I get the index of that particular row which was newly created from the Listview so that I can set its SelectedIndex.
