i want to show a jQuery UI Dialog from Codebehind and need to refresh it after postbacks. The dialog is a control to filter and find data. So the user selects from DropDownLists and enters text in TextBoxes, clicks a "Apply-Button", an asynchronous postback happens, the data gets filtered according to the user's selection and the result will be shown in a GridView. Therefore i need to update the UpdatePanel around the GridView. The asynchronous postback works with help from these links: jQuery UI Dialog with ASP.NET button postback http://blog.roonga.com.au/2009/07/using-jquery-ui-dialog-with

I need to scrape query results from an .aspx web page. http://legistar.council.nyc.gov/Legislation.aspx The url is static, so how do I submit a query to this page and get the results? Assume we need to select "all years" and "all types" from the respective dropdown menus. Somebody out there must know how to do this. As an overview, you will need to perform four main tasks: to submit request(s) to the web site, to retrieve the response(s) from the site to parse these responses to have some logic to iterate in the tasks above, with parameters associated with the navigation (to "next" pages in

I have a simple form created using Ajax.BeginForm : <% using (Ajax.BeginForm("Update", "Description", new { id = Model.Id }, new AjaxOptions { UpdateTargetId = "DescriptionDiv", HttpMethod = "post" },new {id ='AjaxForm' })) {%> Description: <%= Html.TextBox("Description", Model.Description) %><br /> <input type="submit" value="save" /> <% }%> The controller is wired up and returns a partial view that updates the DescriptionDiv . And it all works neatly. Now I would like to be able to submit this form without having the submit button (via a clik on a link or on an image or whatever).

According to Microsoft the FileUpload control is not compatible with an AJAX UpdatePanel. I am aware that a PostBackTrigger can be added to the submit button of the form like this: <Triggers> <asp:PostBackTrigger ControlID="Button1" /> </Triggers> The problem is that this forces the form to perform a full post-back which voids out the whole point of using the UpdatePanel in the first place. Is there a workaround to this issue that does not cause the whole page to refresh? I know of a third party component that can do that. It's called " swfupload " and is free to use and open source, and uses

What is the best way to reset the scroll position to the top of page after the an asynchronous postback? The asynchronous postback is initiated from a ASP.NET GridView CommandField column and the ASP.NET update panel Update method is called in the GridView OnRowCommand. My current application is an ASP.NET 3.5 web site. EDIT: I have received excellent feedback from everyone, and I ended using the PageRequestManager method in a script tag, but my next question is: How do I configure it to only execute when the user clicks the ASP.NET CommandField in my GridView control?
