updatepanel

问题 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:

问题 I have a form that is being dynamically built depending on user selection using Ajax (built in .NET Ajax with UpdatePanel). how can I insert a "standard" ajax loading icon (maybe have it attached to the mouse pointer) while the postback is happening then remove it when the post back is finished? I do have the AjaxToolKit installed if that helps. 回答1: use updateprogress of tool kit :hope this will help you <asp:updatepanel id="ResultsUpdatePanel" runat="server"> <contenttemplate> <div style=

问题 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? 回答1: I know of a

问题 I have a Textbox that changes the content of a dropdown in the OnTextChanged event. This event seems to fire when the textbox loses focus. How do I make this happen on the keypress or keyup event? Here is an example of my code <asp:TextBox ID="Code" runat="server" AutoPostBack="true" OnTextChanged="Code_TextChanged"> <asp:UpdatePanel ID="Update" runat="server"> <ContentTemplate> <asp:DropDownList runat="server" ID="DateList" /> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID

问题 I have a pageLoad function which sets some css on an .ascx control that I cannot change. On page load everything is fine, but when an update panel updates the control, my css is no longer applied. How can I rerun my function after the page updates? $(function() { $("textarea").attr("cols", "30"); $("input.tbMarker").css({ "width": "100px" }).attr("cols","25"); }); This obviously only runs on the initial page load. How can I run it after an update? 回答1: Adding an add_pageLoaded handler can

问题 I have a search page with parameters at the top and a search button with results at the bottom. The entire thing is wrapped in an update panel inside the master page. After clicking the search button it shows the first page. However if you click the next button on the DataPager it does not show the second page. It shows no results for the second page. Any help would be greatly appreciated. 回答1: I think Nick has the right idea. It sounds like you are performing your search and populating your

问题 I'm using bootstrap popover in a update panel in my asp page that it doesn't work. when I put it out of update panel it's OK, please help me. 回答1: There's not a lot to go on here, but when I've run into similar issues in the past it's been because the update panel does a partial postback for an update and the javascript isn't getting bound because the markup changed or was added after the page load. You will need to rebind the trigger (initialize the popover) when the AJAX panel updates using

问题 Probably this is an ignorance of Async postbacks, so let me lob a softball out there. I have three cascading dropdowns in an updatepanel, using these you can pick your Store->Department->Product. A fourth DDL sits outside the updatepanel, and using this you pick your competitor. Different stores match with different competitors. A gridview (also outside) then displays the join of Store->Department->Product->Competitor Price. This works fine when you first load and if you switch to a different

问题 I've got multiple UpdatePanel's on a page and i'm updating 2 of them manually by calling __doPostBack. However the problem is the first call seems to be reset when the second call is made (it never updates the panel that i requested to update first). I've got these calls wrapped in setTimeout, but it does not seem to help. Any suggestions on how to make both calls work? 回答1: You could probably do this on the server side of things: UpdatePanel1.Update(); UpdatePanel2.Update(); This causes the
