Forms Data Controls :: ListView Does Not Insert Item?
Mar 13, 2010
What I'm trying to do is: I have a listview control on my page and in my code behind, I created an SQLDataSource object which I defined its Select, Delete, Update and Insert Command strings. I then binded that datasource to my listview. When I load the page, it's obvious the select command works. however, when I perform the insert, the ItemInserted event triggers, but the itemInserted doesn't trigger and there is nothing inserted in my database.I'm not sure what to do here. I also hard coded the insert values in my insert command. So it's not depending on the form values.

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?

How can I use required field validators in the insert item template in a listview control? The empty fields in the insert item template are preventing the user from deleting or updating ay other row.

I have a listview displaying my products and an "Add to Cart" button in the item template. the button fires 2 functions that should add that specific products information and the order details to two SQL database tables(Orders and Quantity(intersection entity between Orders and Products tables)) then you get redirected to the shopping cart page and it should display the item(s) according the specific key in the Quantity table(key is foreign key in Orders)My problem is that i cannot pull any information from the specific item template when i click that button. Need a way to find that specific controls information in my listview. Can anyone help with this?Below is my item template...
<ItemTemplate>\
<td id="Td2" runat="server">
<table ID="Prodtable" runat="server" width="130px" height="95px">

Suppose I have a horizontally oriented ListView that always shows 4 items and also has a left & a right button: < A B C D >
Now, let's say I have a DataTable containing 20 entries, with indices ranging from 0 to 19.
When the page first loads, this is what'll be displayed: < 0 1 2 3 >
Assuming those buttons are regularly configured DataPage buttons then if I press the right one we'll get this: < 4 5 6 7 >
And if I press the right one again we'll get this: < 8 9 10 11 >
But suppose I'd like the left & right buttons to only scroll one at a time, so that pressing the right one at the start results in this: < 1 2 3 4 >
In such a case, is there a way to configure the DataPager to do this or should I instead introduce regular buttons and perhaps have them call a hidden DataPager?

have a nested listviews:
Listview1-Item1
<if Listview1.selected index = 0>
Item1NestedListView - item1
Item1NestedListView - item2
When a user selects an item in the parent listview, the nested listiview displays as part of the selected item template - when a user selects an item in a nested listview it correctly populates a third, separate listview. To make sure I'm being clear, I have a parent listview with many rows and each of those rows has a nested listview, that is only populated and displayed when the row is selected. The parameters for the nested listview are set in the ItemDatabound event of the parent.
I had this working fine when both objectdatasources were on the aspx page. However, requirements have changed and we would like to pass a class to the BLL. I cannot figure out how to do this using a datasource on the aspx page. I can pass a class doing a databind in the code behind. However, if I do the databind in the code behind, the SelectedItem template does not get displayed as I would like. I need to find the the selectedIndex for the parent listview in SelectedIndexChanging. however, when I click or 'select' an item in the parent listview, the page refreshes, the ItemDatabound of the parent of the parent fires NOT knowing the selectedindex, then the SelectedIndexChanging event fires changing the SelectedIndex. By this time the Listview is already on the screen without the selectedItemTemplate containing the nested listview. If I click on another item, the when the page refreshes it knows the selectedItemIndex chosen before and displays that SelectedItemTemplate containing the selected index.

I am trying to export a Nested Listview to Excel, but I am having issues with the code recognizing the records in the ListView. When I do a FindControl, that code works fine.The Issue arises when I try to loop through the Items of the Nested Listview. The Count always comes back as 0 (zero). However, if I do a watch on the nested listview variable and navigate to the Items collection, then the count is updated with the correct content. I've tried forcing a Databind() on the 2nd Listview, but that really shouldn't be necessary as I know the records are there. As a result, I am having issues Exporting the Data to Excel since only data from the Parent ListView is returned.

I have one ListView. If someone selects an item (as LinkButton) in the ListView, then the program will retrieve the record value and then converted the record value into ArrayList.
Is there VB code example (or showing a link) how to write the program in one page aspx?

i have a listview. The listview contains a usercontrol with ID="ucEquationBuilder1" which is added only! in the SelectedItemTemplate.I've came along some post which stated you can't find the control in the SelectedItemTemplate unless it is also in the the ItemTemplate.
To me this sounded ridiculous. Untill i ran some tests, and indeed i was able to find all other controls (TextBox's Labels) which where both inside the itemtemplate and the selecteditem template.
To me this is quite frustrating. Is there a way to retrieve the control which is only inside the SelectedItemTemplate without adding it to the itemtemplate?

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.

Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. error when I place a drop down list into my instert item template of my listview, but I have the exact same control in my edit view and it works fine, any reason I am getting this error? I know what it means but why would it work in the edit mode, and not the insert mode?

How would I go about showing the insert row in a ListView? Intially, when I went to configure the ListView, the Enable Update, Delete and Insert checkboxes were all greyed out. I changed a bit of the template code and couldn't access this screen anymore but that's not really a big issue.The Edit and Insert templates are present in my source. To get editing working, I simply adding an asp:Button to each row with the CommandName 'Edit'. However I'm a bit confused as to how I can get the insert row to show. Do I have to create a new button there with the 'Insert' CommandName? If so, where should I put it? Is there another way of doing this?
