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?

how we find the listview index of row in case of item databind
View 4 RepliesI 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 am using list view to display the the data but i am getting an error like An item placeholder must be specified on ListView 'ListView1'. Specify an item placeholder by setting a control's ID property to "itemPlaceholder". The item placeholder control must also specify runat="server.Even i have specified the itemplaceholder id but no use still same error.

I'm using a ListView and have two buttons that allows users to delete or edit a item from the list. Below is the code for the buttons:
<td>
<asp:ImageButton ID="ButtonEdit" runat="server" ImageUrl="~/Styles/Images/Edit.png" ToolTip="Edit" OnClick="ButtonEdit_Click" />
<asp:ImageButton ID="ButtonDelete" runat="server" ImageUrl="~/Styles/Images/Delete-Red-Cross.png" ToolTip="Delete" CommandName="Delete" />
</td>
When the user clicks the edit button I want to pass the unique identifier from the item in the list to the parameter string so I can retrieve it in the edit page. how to retrieve the ID from the selected item?
I have 2 pages. Retrieving selected values with session from my first page then

I wish to remove the edit button in the formview item template if a particular user is not authorized, how do you accomplish the removal?

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.

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?
I am trying to insert manually new items in a Listview control using objects. The item seems to be inserted, but when the page is sent back to the browser, there is nothing there. Here is the code that I am using:
[Code]....
I can assign a list of object to the datasource, but when I try to input a new object to the list of items from the ListView, it doesn't work.
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 have a listview that renders like this:
yearsexp: 4
desc: a description text on the row databound, if there is no value for yearsexp or desc, I would like to make it not visible. The other one needs to still be visible. So far I have

I have a page where I use the ListView and DataPager.My listview is populated as a table where each row has a bit data a dropdownlist with some values and a link button. Now I am trying to pick out the selected value from dropdown list when I kick on my linkbutton. As long as I'm on page one, everything is woriking fine. But if I go to page three then I can not pick out the value I selected in the dropdownlist. I have tried to add a textbox in the listview and then I am able to get the value out I typed into the textbox independent which side I'm on.
Why can I pick out the value from textbox but not the selected value in dropownlist?
