Forms Data Controls :: How To Push Down Outer ListView From Nested ListView Control
Mar 13, 2011I 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?
View 8 RepliesC# - Nested Editable Listview Bound To Object
Dec 15, 2010I have a problem similar to the one found in this Question I have a ListView nested inside of another listview. The outer Listview is bound to an object in the codebehind.
listViewOuter.DataSource = myObject[0].someProperty;
listViewOuter.DataBind();
Where someProperty is a List of another object(mySecondObject). The inner Listview needs to be editable and it is bound in the markup to another property(secondObjectProperty) of type List in the mySecondObject as such:
DataSource='<%# Eval("secondObjectProperty")%>'
This works fine to display the data, however I cannot figure out how to put the nested listview into edit mode. I am handling the OnItemEditing command and setting the EditIndex to the proper row however the mode of the nested LV never changes. I have tried every imaginable combination of updates panels and rebinding both the inner and outer listviews however nothing seems to work
heres the LV markup(psuedocode)
<updatePanel>
<asp:ListView ID="outerListView" runat="server">
<layouttemplate here>
<itemTemplate>
<aspListView ID="innerListView" DataSource="<%# Eval("secondObjectPropery")% onitemEditng="editMethod">
</asp:LsitView>
</itemTEmplate>
</asp:ListView>
</updatePanel

Forms Data Controls :: Referencing A Nested ListView In A ListView?
Aug 17, 2010Ok, 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.

C# - Bind The Datasource Of A Nested ListView To The Parent's ListView Datasource?
Dec 13, 2010I have triple-nested ListView controls on my asp.net page, each nested within another. I use the OnItemDataBound event in the 1st ListView to set the DataSource of the 2nd level ListView. The 3rd ListView is contained in the of the 2nd ListView. I want to assign the same DataSource to both the 2nd and 3rd level ListView datasource controls, but I cannot figure out how to access the 3rd level ListView in order to do that.
[Code]....
The level1_ItemDataBound method finds the level2 control, casts it as a ListView, sets its DataSource and executes the DataBind. At this point I'm stuck trying to get Level3.DataSource to be set to the same as Level2.DataSource.
How To Access The Bound DataSource Item In The ListView's DataBound Event
Sep 22, 2010I know the question has already been posted here but we didn't get to an real solution.I have bound my ListView to an SqlDataSource and I want to write some text in a control present in the view created in the LayoutTemplate depending on some properties of the rows returned.Obviously, I'm using the ItemDataBound event to feed my items but this is not the point.
The spontaneous solution was to bind the ListView.DataBound event and access the raw datasource (a DataTable?) and do the required calculations.I inspected the Items property and, despite it was not empty, the related DataItem property was null.The only work-around I can come to is to execute the calculations in the ItemDataBound event and accumulate the result in some private fields. But it's really ugly to see and makes harder to get some of the required values.

DataSource Controls :: Sorting A ListView Bound To LinqDataSource Based On Child Object?
Jul 22, 2010This was a pretty disappointing moment - when databinding, using Eval("Contact.LastName") would work. It nicely evaluates the related Linq object's member LastName. If the "Contact" object is null, no error is thrown... instead the field is simply null.
However, the same does not hold for sorting - if there exists a null entry (this object does not have a Contact) then the LinqDataSource throws a NullReferenceException. This means that, if you ever have nulls on your foreign-key objects, you can't use sorting headers in the ListView.
This makes the feature moderately useless - I have to roll my own properties for every single field I'd ever want to sort on. That's insane.
Type Of Data In GridView / Listview Bound - Template And Auto Generated Fields
Aug 18, 2010Background: I'm populating lots of asp.net c# GridViews and ListViews from a database and subsequently users may export them to Excel. I want export as native Excel (not html). I can't use office automation, and I'm using JET which works fine. I have no control over users' machines. Question: When doing the export, you have to tell Jet what type each field is, in my case "text" (varchar) or "numeric" (double). The difference is that if you export a numeric column, the users can sum the data in Excel, where as strings are exported with a leading apostrophe and so are not much use in arithmetic.
Currently I parse the first data row of the Grid/ListView, check if each value is numeric or text, and assign a type to the column accordingly. That works, except for when I have something in the first column which looks numeric but in fact is a text string. I don't want to parse every row in order to be sure I have the correct data type as some of these exports are quite large. When I load the Grid/ListView from the database, the database certainly knows what type each field is. So my question is... how do I extract the type of the database item behind a a Grid/ListView item? I could explicitly code it as an attribute on the item, but that's duplicating information I already have, if only I can get to it. I know that where I have a DataTable then I can get the underlying type from that, but mostly I don't have tables handy, just the Grid/ListView. Note that Jet will throw if you try to insert an empty string into a nullable numeric column. The way to do this is to omit that column name from the insert statement, or output a zero.
C# - Access Parent DataItem In Nested ListView
Mar 31, 2010So I've got two listviews; one nested inside the other. The parent is being bound to a collection of objects that contain fields such as MaxPrice, MinPrice, and SuggestedProducts. The nested one is being bound to the SuggestedProducts collection of the parent item. How could I reference MaxPrice and MinPrice in the nested listview? Is it even possible? If you need any clarification, leave me a comment and I'll update my question.
