i set CommandName="Select" in Link Button and performed this:

How can I get a DataItem in a listView in the ItemEditing event?? I thought it would work similar to a repeater but I am at a loss. I need it to do something like this:
protected void lvUsers_ItemEditing(object sender, ListViewEditEventArgs e)
{
var item = lvUsers.Items[e.NewEditIndex];
[code]...
So 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.
View 4 RepliesI have a ListView with many advanced controls and html tags. ListView is bound to collection of profiles when first profile in collection is current profile. current profile has few differences from other profiles ie. flash embed, js and some other stuff. I can access inside of my ListView Container.DataIndex property which gives me 0 as first item in index but i'm unable to use inline If statements like so
<% If Container.DataIndex = 0 Then %>
do stuff
<% EndIf %>
this is because i must place pound to access databound item but neither this
<%# If Container.DataIndex = 0 Then %>
do stuff
<% EndIf %>
How can i make inline If ?
I have a ListView with a template, it puts a bunch of data in, like X Y Z.
I want to hide show some columns based on criteria, so I have ItemDataBound event, but I don't know how to get the actual listview row so I can do things to do it.
I want to access the data that was databound to my list view when handling list view events such as:
protected void List_ItemDataBound(object sender, ListViewItemEventArgs e)
or
protected void List_ItemCommand(object sender, ListViewCommandEventArgs e)
Inside the events, I can not access the data via somthing like Eval("ID")
Currently we are using a very hacky solution:
string id = e.Item.FindControl("lblID").Text;
Where lblID is a hidden control that is populated with data in the aspx file using:
<asp:Label ID="lblID" runat="server" Text='<%# Eval("ID") %>' />
My eyes bleed when I look at this, Is there a better way?
have a listview with a list of comments. I would like to add the avatar of the person that posted the comment to each comment. To accomplish this I need to find the ListViewItem find the UserID get the avatar URL and add it to the ListView. I am sure I can do all of this in the ListView Databound event but how?
protected
void ListViewViewComments_DataBound(object sender,
EventArgs e)
{
try

I 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.
have an annoying problem. i'm trying to update single items in a databound listview. but when i click the update button it gives me the cannot insert NULL value. it doesnt seem to read anything from the textboxes which i have databound from the database. even though text is clearly shown...
i have setup my update statement and parameters, it uses the Update command name and ItemUpdating event. i catch the data from the textboxes by using e.ItemIndex and use the text assigned to the parameters in a SqlCommand.
The thing i'm aiming for too is that when an item is updated it stays on the page where the item was updated, (i was using response.redirect before but it went against my aim since the whole page reloaded)
I have 2 pages (let's say one is a.aspx and the other one is b.aspx). In the b.aspx, there is a nested listview control (let's say outer listview and inner listview).Therefore, there is an event on databound for the outer listview. so basically, the event will programmatically bind the datasource for the inner listview.
Now, in a.aspx there is a button to open a new window (with unique window name) b.aspx. The very first time click on the button, a.aspx opens a new window for b.aspx without triggering the databound event. However, the second click and so on will trigger the databound event which is causing an error because there is no data yet in the outer listview.My question is, what could have possibly triggered the databound event while there is no data in the listview?
i have a FormView, and i already have a Label control that gets the value of theselected propery inside the FormView, so each time the FormView displays data, i have a Label control that displays individual values, according to the value of the FormView, here is the code:
[code]....
What i would like to do is to know how i could add a DataList instead of a Label, and then each time the FormView databinds an item, to show the value of the DataList How would i go about doing that?
I want to render something like this (with ASP.Net Controls in the codebehind):
<ul>
<li class="first"><h1>This is a caption</h1></li>
<li><a href="#" title="" target="_self">Foo</a></li>
<li><a href="#" title="" target="_self">Foo1</a></li>
<li><a href="#" title="" target="_self">Foo2</a></li>
<li><a href="#" title="" target="_self">Foo3</a></li>
<li><a href="#" title="" target="_self">Foo4</a></li>
</ul>
<ul>
<li class="first"><h1>This is a another caption</h1></li>
<li><a href="#" title="" target="_self">Foo5</a></li>
<li><a href="#" title="" target="_self">Foo6</a></li>
<li><a href="#" title="" target="_self">Foo7</a></li>
<li><a href="#" title="" target="_self">Foo8</a></li>
<li><a href="#" title="" target="_self">Foo9</a></li>
<li><a href="#" title="" target="_self">Foo10</a></li>
<li><a href="#" title="" target="_self">Foo11</a></li>
</ul>
The amount of li elements that will be rendered into each ul is determined at runtime. Each link in a li belongs to into a specific ul (the one containing a specific caption. Imagine this as a kind of a treeview with nodes and subnodes) During the bind Event I need access to an ASP:HyperLink that will be rendered into the a-element. Which databound ASP.Net control should I pick for this? Looks like a repeater in a repeater, which should make the databinding process ugly. I'm thinking about creating this HTML-Output with StringWriters myself.
So I have a ListView (assignmentsListView) in an UpdatePanel, being filtered by a DropDownList in the same UpdatePanel. The DropDownList has a list of persons in it and uses autopostback, and the ListView shows the tasks those persons are assigned to.
I am trying to use code similar to this:
[code]....
When I first load the page, the DropDownList shows the first person in the list, and the ListView correctly shows that persons tasks.
If I then select a person who I know has zero tasks, I get an error at the RegisterPostBackControl() method, saying the passed-in control cannot be null.
When debugging, at the RegisterPostBackControl method, it shows that the ListView Items collection has >0 elements in it (the number of elements matches the person selected before the current person).
I use this bit of code in the code behind a OnRowDataBound comand of a gridview:
Code:
(int)DataBinder.Eval(e.Row.DataItem, "SectorID")I have made some changes to my Class so that SectorID is now a list of ints. How do i return the first item in the list using the above method?
I'm using DataTable for DataBinding.
Can I access dataitem (I think its suppose to be DataRow in my case) from aspx?
Something like:
<img alt="" src='<%= DataItem("ColumnName") %>' />
I am accessing a DetailsView from the following event
public void dvDetails_DataBound(Object sender, EventArgs e)
I am casting the sender to my detailsview like so
DetailsView dv = (DetailsView)sender;
Now when I look in "dv" I can see the DataItem property has the data I want in it under a field name, but I dont know how to write the code access the value??
The field name is shown in the dataitem property as "_DTMON_F", I tried to say
Datetime myDate=dv.DataItem["_DTMON_F"]
BUT C# doesnt like the syntax
I have some code like this:
<div><%# DataBinder.Eval(Container.DataItem, "M_ClassProperty") %></div>
<img src='<%# DataBinder.Eval(Container.DataItem, "M_AnotherClassProperty").To<string>() %>'
but there is no component which wraps this code like Repeater, DataList or something like that. How can set the set a DataItem to this code to show the values of an object of a class.
I have a ListView in which i have a function that creates images for users. I pass userGender,userImage1name,userIsImage1Aprooved values to the function in which i generate image.ie. if user has approved image i return it back, otherwise i return default image based on gender.y question is, is there any way to avoid passing 3 parameters to that function and to pass whole DataRow so i can get values of columns i need?In reality i pass about 12 parameters just made it easy for you.ie. i want to achieve something like that <%# GetImage(Container.Item) %> while in GetImage() i would be able to access Item("some_column_name") or C# version Item["some_column_name"].
View 2 RepliesAfter postback (click on a button) in my ASP.NET form, all the DataItem of my form are null. Why? What should I do to retrieve the content of the DataList even after postback?

From Google i figured out these can be used to bind the columns in GridView to ArrayList. But what is "some property" ?For example i have a ArrayList in .aspx.cs as
static ArrayList componentSelectionArray = new ArrayList();
so can i just write in grid view to bind a arraylist to grid view columns as:
<asp:GridView ID= "GridView1" runat="server" AutoGenerateColumns="true">
<Columns>
<asp:TemplateField HeaderText="ComponentName">

I have a repeater control bound to a collection of objects. When I fire off the button_onclick event, I need to have access to the dataitem to get the object properties. Here is what I have and my question is how do I access the underlying objects in a repeater in a button_onclick event

I'm trying to pass a string value to a javascript function from a LinkButton's OnClientClick event, but the function is receiving "<%# Container.DataItem %>" instead of the value. Here's the code:
OnClientClick="javascript:SaveQuotaGroupCode('<%# Container.DataItem %>');"
The container is a collection of strings. Why is it not evaluating?EDIT: This is located in a nested ListView. The datasource for the inner ListView is a property in the datasource of the outer ListView.
I've bound a IeNumerable<class> to a repeater.On the repeater i've got a ItemDataBound.Right there i want the value of 1 of the items in my string s.So i've build this code.But if i run it i get this error:
System.Web.HttpException: DataBinding: 'dftv.AutoDiskClass+Merk' does not contain a property with the name 'nMerkID'.
if i run it again and put a breakpoint at this row, and push the DataItem, i get this information.
But how can i get the value of nMerkID in my string?The class i put in it is:
public class Merk
{
public string nMerkID = "";
public string Merknaam = "";
}
I am trying to access the current 'active' top level node from a sitemap repeater from outside of the ASP.NET repeater used to render it, this is for CSS styling purposes as I want to place the child nodes on the subsequent row with different styling horizontally. At present I have the following code which I can't get to display correctly using CSS.
[code]....
I would like to display the child nodes on the next light blue element which I can do perfectly well from a seperate div if this was not rendered using a child repeater. In the image below Blog and Services are top level nodes and their subseqent nodes (2 for each) should be displayed on the light-blue row below. Is this possible?
