I have created a WPF ListView that uses GridView as its view. Below is the XAML code for my ListView
[Code]....
I am binding data to the Listview through a DataTable using the following
[Code]....
My data is being displayed properly.My question is that when I click on a particular row of data, how do I generate a click event?For Example, when I click on someones name I want a MessageBox to appread.
I need to create Listview control dynamically and also i get columns dynamically .
How can create dynamically LayoutTemplate and ItemTemplate and how to bind data dynamically.
Using a listview control for the first time... I need a button for each item, and of course I need to handle the click event for the buttons... upon clicking a particular button I of course need to know which item the button is associated with so the appropriate action can be taken...
In VS, I can't select the button and see my list of available events in the properties window like is normally done for controls outside of templates like this... what do I need to do?
I am trying to populate the ListView using LinqDataSource data source but the issue I am having is.I need to load the listview on Search button click action.
IN the page_load I kept like this:
===========================================
LinqDS.Selecting += new EventHandler<LinqDataSourceSelectEventArgs>(LinqDS_Selecting);
protected void LinqDS_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{
e.Result = ObjectDS;
}
=============================================
This works fine but this happens on page load,i want this binding to happen on button click?is there a way to do this?
I got an event handler like this, in this event, i wanted to call another button click event. How can I do that?

i have a listview (inside an update panel) in a user control with two columns in each row. the list view is bound to a datatable via a stored procedure. i use the control on a web page and on the click of a button (which is not inside the listview, but in the user control) i want to add a new row at the end of the listview which should add a row with two empty text boxes (one for each column) at the end of the listview.
i am currently able to achieve that, but only on clicking the Add button TWICE.
here's my html code for the listview in the user control
[Code]....
and this is the c# code behind

I would like to change the listview template on a button click event. for example if your in edittemplate i would like to switch to ItemTemplate.i am trying to do this because im writing my own custom update function for the list view. so after i successfully update the row, it doesn't switch back to the default view.
View 1 RepliesOn the items in my listview, I have a button to allow for editing. The strange thing is, that the button only changes to editmode on the second click of the button, and then it doesn't load the data from the item. I have tried to debug this issue, and it does cause a postback on the first click, but nothing happens. Then on the second click, it fires a postback again and changes to the edittemplate, but without any data.
I databind my listview on
if(!IsPostback)

I have a listvieiw with url's in some of the cells. When I click on them they do nothing. I formated the cells to be "hyperlinks" but still nothing.
View 8 Repliesi have a listview which contains a text box and a drop down control (which makes it kind of a layout ...a text box along side a drop down control in each row). there can be any number of rows in the listview depending upon a user entry (an integer).
after i have filled all the text boxes and changed the drop down controls to their associated values (for each text box), i want to save everything that i have filled. i have a SAVE button OUTSIDE the listview, and i want to (probably) iterate through all the rows of the listview and save all the contents in the textboxes to a collection object, where each collection item will be a row with textbox's text and dropdown's selected index value.
I've some webpage with listview control, and double click event on each row on it.
The problem is, that when I double click the row, event is fired, that's fine, but all of the page is selected (dark blue marked, you know...).
Is there some solution to prevent select all in the whole page, or whole aplication itself?

The ItemInserted is the code which is executed twice as shown by debug. There are other events which execute twice also.
One of my webpages has an asp.net ListView control, with an insertitem template defined. I would like to allow the users of the page to enter data in a text field in the insertitem template, press the enter key, and trigger the insert event (which normally happens when you click the 'insert' button). I've tried simulating the button click event in javascript, but that doesn't seem to be working.
View 2 RepliesI 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 ListView control that makes use of a DataPager. In each row of the ListView there is a text box where the user will enter some notes relevant to that particular record. Then they use the DataPager to navigate to the second page of records. If they then return back to the first page in the ListView the text they entered is gone.
Question: Is there a way (through use of a paging event or databound event maybe?) to retain the textbox values between paging events ?
I would like the user to be able navigate backward or forward and still see the text heshe has entered.
I stumbled into a problem which is that FindControl will only return a control in the ListView after the listview has been databound. Here is the code which is not working, and I'm getting the "Object reference not set to an instance of an object error" when I try to add the attribute to the control:
[Code]....
Any ideas on how I can elegantly fix this?

View 4 RepliesI am populating an asp.net listview control from my page_load event. Unfortunately, due to my projects requirements, I have to use a third party control within my listviews ItemTemplate that needs to have database values written to its attributes before my listview control is bound, if this is not the case my control flags a null reference exception error. From some investigation into the listview control, it seems that the only way to do this is through my listviews ItemDataBound event as my thrid party control will hold different value depending on each row.was wondering if it's at all possible to force my listviews ItemDataBound event to fire before I call mylistview.databind();?
View 27 RepliesI have a User Control that contains a ListView. In the user control's code is this event handler:
protected void listView1_ItemCommand(object source, ListViewCommandEventArgs e)
{
Button_ClickHandler(source, e);
}
What's occurring is that I'm explicitly firing an event so that the parent web page can monitor this and take appropriate actions. Thus when the user clicks on a different ListViewItem it triggers the population of associated data elsewhere on the web page.
This all works fine except for one thing: When I first load the control I'm pre-setting the first ListViewItem. Unfortunately, just setting the ListView's SelectedIndex = 0 doesn't fire the aforementioned event handler.
So I started investigating how to call "listView1_ItemCommand" but couldn't figure out how to instantiate the "e" parameter.
I have a listview that has been constructed using tables. I have set the DataKeyNames="SomeTextField" among others. This column is currently not visible in the ListView.
I'd like to populate a textbox on the click of any listview record with the contents "SomeTextField" column.
I'm using VS2008. When a dataset is bound to the DataSource of a ListView, SelectedIndexChanged event does not fire. If I used DataSourceID instead, it has no problem. But SelectedIndexChanging event fires for both.
why and how I can get SelectedIndexChanged event fired when DataSource is used?
using a listView control... I'm trying to use the ItemDataBound event to map a field's native value to a more 'friendly' name... so far I have the code to access the underlying data so the decision can be made for the actual mapping, but I don't know how to actually change the data displayed?
View 4 RepliesI have a ListView (table inside) and it's first row are some TextBoxes for filtering actions.
In the last column I have a button that calls my Search function and filters the records according to the inputs.
[Code]....
My Search function for now only displays a text inside a Label at the top of the page.
When I load the page, I'm using ListViewPesquisa.DataBind() so it shows it's EmptyDataTemplate, but when I click the button inside the event isn't called at all. If I do put some data (any data) in the ListView and it shows it's LayoutTemplate instead, the event is called properly.
I can get around this issue by moving the filter line out of the table, but I'd like to know why is that the button inside the EmptyDataTemplate doesn't work.
I have a list view. Its OnItemCreated event works when page loads and items are displayed successfuly. However when, page index changed it says
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index Followings are my methods:
protected void listview_ShowroomItems_OnPagePropertiesChanging(object sender, PagePropertiesChangingEventArgs e)
{
pager_ShowroomItems.SetPageProperties(e.StartRowIndex, e.MaximumRows, false);
MembershipUser currUser = Membership.GetUser(User.Identity.Name);

I have discovered something strange when using a ListView. I have a listview contained inside an uodate panel and everything works OK until I edit the editItemTemplate to use a LinkButton instead of a Button.When i use a LinkButton then the Page_Load event is fired.
