AJAX :: ListView Refresh With New Data
Apr 8, 2010
I have a ListView and Calendar on the same page. When somen selects a day on the calandar, I want the ListView to be refreshed with new data. However, when I go through the Calendar_SelectionChanged nothing happens until the next page refresh. The function does execute as I have verified through debugging. Going through the code behind everything looks fine, but the ListView just does not change. I can put a timer on the page with no code, and the ListView will not refresh on the calendar event, but does refresh when the timer click event occurs.

I'm trying to combine nested listviews, updatepanel and asyncfileupload, but have run into some problems. I'm having a main listview listing some projects, and in each project I have a nested listview listing some images in that project. I also have an insertitemtemplate, for inserting new images. This template contains an asyncfileupload control. Everthing is contained in one large UpdatePanel, to enable smooth editing of the images and their associated information.
Problem 1:
The fileupload is complete now, and the file uploads as I expect. In the AsyncUploadCompleted event I'm also inserting the uploaded image to the database. So far so good. But when the upload is done, I want to be able to see the newly updated record in my nested listview. But this is not the case. I'm not able to DataBind the listview in the AsyncUploadCompleted, because that throws an exception saying "The control collection cannot be modified....". So, how do I manage to do an async update of the nested listview, showing the new record?
Problem 2:
When deleting items from my nested listview, after the async update the listview shows up without any items except the InsertItem. The items are not removed, a refresh of the page brings them back. Why is the databinding lost during the async postback?

I have a problem when I try to pass in paramaters for a report in my report viewer. I have set up the ObjectDataSource and set the paramaters for 3 text boxes that are on the page. The only way I have found to set the paramaters for the report is the user must fill in the paramaters and hit the refresh button on the Report Viewer toolbar ,but I would like to have the user click a asp.net button insted. Is there anyway to call the refresh method from codebehind?

i my futur webpage i wan't to use ajax. First i tough to use a panel to hold my controls and turn in visible/invisible with buttons. But if i use ajax and i refresh the page and show other controls.
I have a page with 3 different kind of data. in the first you can't type a name, you function, ... in the other more specific and the last one an evaluation. but if i refresh my page to a other what hapends with the data i typed in the first, can it be saved at temporary place. Because at the end all the data will be saved in a SQL database, but it still needs to be possible before it goes into the database to change it.

I have a page that displays data depending upon the date range entered by the user into two textboxes. I have added the CalendarExtender control from the Ajax Toolbox to each of these two textboxes, and I would like the associated updatePanel to refresh with new data whenever either of the two dates is changed. Sounds simple enough, but I have not been able to manage it so far.

I am facing a strange issue while adding some dynamic data in my two divs. First div only contains single grid, while other has grouping grid with collapsible panel. When i add dynamic data in my first div, then after adding data, my div and its scroll automatically refresh, but when i add some data dynamically in my group grids then div content refresh, but its scroll do not refresh. This behavior is producing in Firefox and chrome. It is perfectly working fine in IE. One thing that can help you to solve my issue is that i am implementing continuous scrolling on my grids and adding data dynamically using jquery. Interesting point is that when i click some item and then scroll down, then both div content and scroll refreshes, but when i do not click on any item and simple scroll down to load dynamic data then div content refreshes but not its scroll. Link that i use to implement continuous scrolling is

I have a ListView1 control that his <ItemTempleae> has a another ListView2. ListView2 is surrounded by <UpdatePanel> with trigger and also UpdateMode="Conditional". But, I don't know why ListView2 is not being update as it should, I need to refresh all the page to see the new data enter to ListView2 only. What is the problem? How can it be fixed? I think that the problem is something in the structure. There are about 10 ListView2 with updatepanel surronded them, so when I am looking to update a specific ListView2, it doesn't know which one to update because there are lots of them. What to do in order to solve that problem?

I have an AJAX tab container with 2 panels within aspx page. Each panel hosts an ascx control. Each control contains GridView and FormView that are databound - 1st control to the parent table and 2nd - to the child. The 2nd control/tab contains standard DropDownList that is bound to the parent values so the user can select a parent to create "child" for. everything works fine except when the parent (on the 1st tab control) is created/updates the ObjectDataSource on the 2nd tab does not getting refreshed. Only after refreshing the hole page I can see the new "parent" value in the ddl on "child" page. I use strongly typed dataset. How I can programmatically refresh the DataSource? Simple rebinding didn't make a dent. Do I need to refresh page, the tab container, tab panel?

I have a ListView, I've setup to use an ObjectDataSource, I've created my Layout and Item templates, and I'm able pull and view a list of my data no problem. However I want to add delete capabilities to my
ListView and my reference material tells me to go into the "Configure ListView..." option under the ListView's smart tag, the only problem is I don't have that option, the only three options in my smart tag are "Choose DataSource", "Configure DataSource..." and "Refresh Schema", what am I doing wrong?

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?

Does anyone have an example for how to create a Dynamically Templated Listview with prefernces page to specify which columns & column order)? Also the listview would also have Edit, delete and insert options if possible. And uses the n-tier approach with Bus Layer and does NOT use LINQ.
