I have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?

I am having trouble finding how to solve the following issue :
I am using nested listviews to display Sales and Sales details.
The main ListView displays General Information about Sales and the child ListView displays the detailed information about one sale. the child listview is shown only when the user clicks on a link (see included code, DataBind is made on PageLoad) :
ASPX Markup Code :
[Code]....
C# Behind Code :
[Code]....
If I removed the datapager part, I can manage show/hide the child list view on the button click event. but if I want to use the DataPager with the PreRender event handling, the child listview is not longer shown on button click.

Ok, background first:
The form allows a user to create and edit one estimate.
Each estimate can contain multiple Jobs, which are represented in a ListView.
Each Job can contain multiple Parts, which are contained in a ListView that sits in each item of the Jobs ListView.
A user can add and remove as many Jobs as they want.
A user can add and remove as many Parts to/from each Job as they want.
I have no issues adding to each of these, but I do have a problem removing a single part from a single job.
For a reference, here is one Job in the Jobs ListView on the form:
I want to make sure that no matter what a user does, the part of the form they are working on saves what they have. Removing a row from that Parts ListView is no exception. What I want it to do is save the values in each of those textboxes and then delete the necessary row.
Here's what I have in the codebehind:
[Code]....
The EstimateRow variable I create does not get a value from theListView)HFERID.Parent.FindControl("LVEstimateRow") bit of code. There must be another level of nesting that I'm not accessing correctly, because it can't seem to find that nested ListView.

The Data is from a SQL Data Source:

However I'm not sure what to set the inner listview's DataSourceID to as I need to display just the boards in that category.

I am trying to get my Nested ListView to work. I have my parent List View supplying the correct information, but I can't seem to set the SelectParameter Value for my Nested ListView. I am using SQLDataSources for both. I read your comment about adding a Hidden Field. Where Should that field be located. Right now I have it inside my Parent ItemTemplate but nothing is happening. Currently I have both DataSource outside my Parent ListView. I tried moved the nested ds inside with the list view but I still was not able to grab the hidden field values either. Here's what I have:

I have two listviews. What i want to do is that when the nested listview emptydatatemplate shows i want to put a hyperlink with a querystring in it, the id in the querystring should be the fk in the nested listview. Is it possible to bind the hyperlink with the id in codebehind? I use two object datasources. Does it matter where i put the nested listview now i have it in the parents itemtemplate. Also it seems to be a problem to set the datakeynames in the nested listview, what could be the reaso for that.

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 two listviews. The inner listview (InnerListView1) is in the SelecttItemTemplate of the outer listview (OuterListView1). Both listviews are bind in the code behind. The outer listview displays correctly in the ItemTemplate. Neither Listview Listview displays in the SelectItemTemplate. Both should display when I click the Select button. I just get a postback (flicker). The display should include the selected record of the outer listview and the inner listview.
Shown be low are code snipets of the.
Markup:
<asp:ListView ID="OuterListView1" DataKeyNames="entryid" runat="server" EnableViewState="False" EnableModelValidation="True" InsertItemPosition="LastItem" OnItemDataBound="OuterListView1_ItemDataBound" OnSelectedIndexChanging="OuterListView1_OnSelectedIndexChanging"

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 a list box in a list view control. I want to access the value of the listbox. I have fixed the height of the list box and the box has scroll bars. If i change the number using the scrollbar and then click on the number (turning it blue) everthing works fine. If I simply change the number using the scrollbar the system throws the error below. Can anyone tell me how to get this to work simply by using the scrollbar to select the number (without having to also click on the number itself) This is the error that is thrown

in the nested ListView (or the child ListView), the edit command does not work.
It seems that the <EditItemTemplate> is not properly excecuted by the edit button in the <ItemTemplate>.
Interestingly, the edit command in the parent ListView works well.
The insert and delete commands in the nested ListView also run without any problem.
But I get no change by pushing the edit button which is located for each reply (the item of the nested listview)
Here is my code.

I am using a nested listview to display a seperate grid for each group of data returned from my db query. To get this working, I have adapted a piece of code to group the data prior to it being bound:
[Code]....
I am then using the following html markup:
[Code]....
[Code]....
This works as I want it to however some of the fields within the nested table need to be formatted as currency so I am trying to use Eval and {0:c} to do this however the moment I use Eval, the data items cannot be found
DataBinding: 'System.Data.DataRow' does not contain a property with the name '0'.

Is there a better, cleaner way to do this in ASP.NET 2.0?
An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.
The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.
The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.
