When Postback A Second Time Then The Page Will Be Updated With The Value I Set?
May 27, 2010
I'm using the following syntax to bind to a div element:
<div id="previewdiv"><%=Preview%></div>
Where Preview is a property on my page.The catch is that I'm creating this in Javascript on a new page in an onclick event. On the server side, I'm able to reference the new page via this property but for some reason when the page is postback the variable is getting set to the default initialized value and not to the value that I set in my page, i.e Preview = string. When I postback a second time then the page will be updated with the value I set.I could perhaps move the code to the Init but I need to get values from controls to Initialize this property.
I have an ASP.NET page using the AJAX library. There is a dropdownlist inside an UpdatePanel, which on index changing is supposed to update a different UpdatePanel to modify a grid control.But after the page first comes up, and you adjust the ddl, the entire page postbacks, followed by a (correct) partial postback. After this one time, every other usage of the ddl performs correctly, trigger partial postbacks.
Both the panel and the ddl are being added from code. The UP is Conditional updates and ChildrenAsTriggers = true. The dropdownlist is AutoPostBack true and has an event set up on SelectedIndexChanged.So what is going on? I've tried adjusting every setting I can think of and still the page completely refreshes once, then works fine after that.
I have a master page which contains a treeview and a linkbutton. i have used 3 different stylesheets for the same page and those are listed in dropdownlist on the same master page. on dropdownlist change() event stylesheet of the master page change, i have 1 default style sheet which will come as master page loads.
now the problem is when i changed stylesheet from dropdown list, stylesheet changes the master page , but after that when if i clicked on treeview or linkbutton the stylesheet is restored to default one.
i have written following code
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
I've got a repeater which is placed inside an updatepanel. When the user enters a new value, the repeater is updated without a postback. Is it possible to get the row that was updated in JQuery so that I can place an effect on it to make the change less subtle? For example, I'd like to fade a new color in on just the row that was changed.
I have a website and I want to include a "Last Compile Time: XX:XX:XX" in the footer of the website. Is there an automated way to alter the contents of an asp:label at compile time?
I have a ASP.NET 1.1 web application page which is built with .net framework 1.1 and in GridView the data is displayed.I want when they select multiple items then data is updated but without the complete postback of the page.
I have a grid view that is dynamically created.In which every cell in the girdview has a 2 textbox (cTxtboxQty,ctxtWorkOrder) and 2 label.
When user click on the cell, a pop up come out and user are able to change the text inside the cell and click save.After that the pop up close and changed data immediately reflected on the screen.
My problem is:
After my data are changed and updated to database on the pop up page and having it post back to the parent page , my dynamically created textbox in gridview retain old value even new value has been assigned to it.
This sound very weird but i have no idea how to solve this.
My client side code is as below :
[Code]....
[Code]....
[Code]....
[Code]....
I have tested many times and find out that it might be the page hold the old value in memory, so that even we have updated the textbox value, after postback, it still keep and show the old value?
I have a page with two updatepanels both which have thier triggers outside of the panels themselves - I am setting the triggers using in the pageload event. This is how it works - there is a repeater that holds a list of links which gets set when the page loads (this is outside of the update panel). The first udpatepanel has a trigger set to the itemcommand of this list of links - it then goes out and gets the sub links and fills a repeater that is located in the update panel. - so forgetting all about the second update panel on the page... If I set the panels updateMode="conditional" then it doesn't render till I click the link twice. If I put a breakpoint in the code I can clearly see that the code is executing and that there is no error but again... Nothing renders
- I click the link again it renders. If I take out the UpdateMode="conditional" statement all is well... But I don't want that cause I two update panels on the page.
The second one also has sort of the same problem - The trigger I have set for it the ItemCommand for the repeater in update panel one... when I click one of the linkButton's in the first updatepanel sure enougn I see the code execute return my results and all seems well however there is nothing rendered on the page. BUT!!! When I click one of the main links on top (remember these are trigger for updatepanel one) my second repeater inside of updatepanel2 is shows up on the page.
What is causing the partial postback not to render anything?
I know this is confusing so I hope I explained myself well enough. I will just post the ASPX so you can see how I am setting this up - I don't think you need to see the code behind... If anyone does then I will post it.
Again - all this is to with the updateMode - when I remove it (as I did in this code sample) it works and renders however I don't want both updatePanel to get updated at the same time.
I'm at my wits end on this one looked/Searched/Played/Experimented and I need your help if you can.This page is going to be primarily used on a mobile device using Win Mobile 5 Need to Accomplish:Prevent Postback(serverside) of Page using JavaScript (Postback's slow down the page on mobile device)
I have an asp.net intranet site hosted on IIS on my computer.
On one page you can enter two user id's and get a side by side comparison of their roles in our (custom app) system.
I often use it to add roles when I'm setting up new users. After running the query, if i change a role and run the query again it will not show updated results. It's being cached somehow. I have to go to another page and come back and them run the query to get updated results.
How can avoid having to navigate away to get the updated query results displayed.n
I have some asp.net pages that read and write cookie values. During the life cycle of a page it may update the cookie value and then need to read it again further in the code. What I've found is that it's not getting the latest value of the cookie until a page refresh. Is there a way around this? Here's the code I'm using to set and get the values.
public static string GetValue(SessionKey sessionKey) { HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiePrefix]; if (cookie == null) return string.Empty; return cookie[sessionKey.SessionKeyName] ?? string.Empty; } public static void SetValue(SessionKey sessionKey, string sessionValue) { HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiePrefix]; if (cookie == null) cookie = new HttpCookie(cookiePrefix); cookie.Values[sessionKey.SessionKeyName] = sessionValue; cookie.Expires = DateTime.Now.AddHours(1); HttpContext.Current.Response.Cookies.Set(cookie); }
I have a long running asynchronous process which returns a total of around 10-100 results over a 5 minute period. I want to update the page with the progress of the job and also show each result on the page in a list that grows dynamically as results are returned, all without any postback or page refresh.
When an asynchronous postback happened inside update panel, another postback happens also for MasterPagenot only update panel embedded page .I want to prevent this MasterPage postback . is this possible ?think like i have a MasterPage and another page which is test.aspx which is content page of MasterPagei have update panel at test.aspxwhen asynchronous postback happens at this test.aspx update panel it also loads MasterPage Page_Loadi want to prevent this (it should not also load MasterPage Page_Load)
I have a webpage with multiple updatepanels on. One of the panels takes a long time to load. I therefore start a timer on page load and the timer.tick event populates the accordion control within the panel. Because of the amount of data I have used a paged data source and have link buttons to scroll through the results.
I need to implement animation, both on the initial page load and each time the button is clicked to move through the pages. The animation is, show a loading icon and hide the accordion/grid, once the data is loaded, display the accordion/grid and hide the loading icon. I have tried both the PageRequestManager and AnimationExtender, which I fail to get working for both the initial page load and Updating/Updated events.
Is it possible to populate the updated data from the database to a repeater with out refreshing the page and with out using an update panel? This is my requirement.I have an option to save Name & Age to the database
Name <*textbox accepts name> : Age <*textbox accepts the name> Save Button
I run through some code in my debugger that is definitely changing the value of a label on a master page. But it's not changed on the page:
// set the label on the masterpage olbl.Text = Session["TestScriptCount"].ToString() + " Test Scripts"; Label olbl = (Label)Page.Master.FindControl("TestScriptCount"].ToString() + " Test Scripts";
