Web Forms :: Link Button With JavaScript / Window Updates But Does Not Refocus By Putting It Back On Top
Feb 12, 2010
I have a link button on my page which has both an Oncommand event and an OnclientClickevent.
The idea is that the oncommand updates some data via a postback and redisplays the page with the updates. The onclientclick event opens a new window.
The new window is named so there is only ever one instance of it.
What I'm trying to do is this.
Open a new window (if its not already opened) and ensure it is on top of the parent window. The new window is a smaller size so the parent window is still visible beneath. On the first occurance the new window opens above, however when I refocus on the parent to click again, the new window updates but does not refocus by putting it back on top.
I am trying to navigate it to another page using Link Button and in the .cs file, I am using Response.Redirect. But I want it to the open in a new window.
The reason why I cant use hyperlink is I cant use Command Arg and Command Name which I am using in the Link Button.
I tried the below Javascript, But it's coming as a pop up for the first time when it loads. I don't want it in that way also.
protected void GvInvoice_RowDataBound1(object sender, GridViewRowEventArgs e) { DService.IN_Invoices inv = e.Row.DataItem as DService.IN_Invoices; if (inv != null) { Label lblInvoice = (Label)e.Row.FindControl("lblInvoice"); if (lblInvoice != null) {
Here I am trying to get invoiceId throgh lblInvoice andmy invoices are atored as same as invoiceno.Pdf... ImUnable to open That InvoiceinnewWindowButIf i useBelowLineIts working fine.
I have a asp.net page that has a list of items. When one of the items from the list is clicked a details page is displayed. This details page has a link button to show a popup for history of the item. The details page also has a button with text 'Back'. The back button has onclick event set to "javascript:window.history.back();".
This back button works fine and goes back to the first page. However when the user is on the second page and opens the pop up by clicking on the link button, the back button stop working and displays Webpage has expired message.
In the page there are two links. When i click the first link it opens a window in a new page. I do this by using the above code.
I am clicking the second link in the page and navigating to another page. Now i am clicking the browser back button. Supprisingly its opening the first link.
How clicking back button is opening the link in the page. I am using c# .net 2005.
I have two pages A.aspx and B.aspx Page A.aspx opens B.aspx as modal popup by javascript function window.showModalDialog("B.aspx"); Page B.aspx has two text boxes (Login, Password), <asp:Button> control and button click event in server code. Problem is when I click on the submit button it opens me B.aspx page in new third window How is it possible to not open new window on submit button.
I've got an asp.net page that uses dynamically populated DropDownLists and OnSelectedIndexChanged events. A few days ago I found a defect where hitting the back button would load the previous page from the browser's cache, so the DropDownList would already have a selected index (hence the OnSelectedIndexChanged event would not fire properly as it didn't have the default selected index). I understood the issue and googled around. It's a well known issue that doesn't have an easy solution because of how the browser interacts with the page. After a bit of thought, I went with a trivial javascript solution to reset the ddls:
var gvTable = document.getElementById("foo"); if (gvTable != null) {
[code]...
This worked well and I was happy. Until I tested it in IE. In IE, it appears to run the script, THEN load the cached values of the DDL. That is, I observe the DDL snapping back to the 0 index, and then suddenly dropping down to the previously selected value. I'm sort of at a loss here, I typically debug in firebug, but this works perfectly in firefox and chrome.
I have an ASP.NET page that contains two div's. Both have search fields and a search button contained within each of them. When I first come to this page, Div A has the class 'SearchDiv' while Div B has 'SearchDivDisabled'. These classes change the appearance so the user knows which search type they currently have enabled.
When Div B is clicked, JavaScript changes it's class to 'SearchDiv', and changes Div A to 'SearchDivDisabled'. This all works like a charm. The problem I have is when a user changes to Div B, clicks Div B's search button (which obviously redirects to a results page), and then uses the browser's back button. When they return to the search page, Div A is enabled again, and Div B is Disabled, even though they last used Div B. In the search button event handler I set the class attribute of the Divs before I redirect, hoping this will update the page on the server so when the user returns, their last-enabled Div will still be enabled (regardless of which one was enabled when the page was first visited).I believe this involves the ViewState, but I'm unsure why the class attribute is not saved so when the user returns to the page it is restored.
RedirectToResults() is called from the actual button event handler with the enum representing the selected search panel and the results page url. SearchContainers is a dictionary mapping an integer to the search Div. The important code is the last line, where I'm updating the selected search container with the 'active' search class, rather than the disabled one (which I assign to the other div(s) )
Additional Update: I have been battling with this issue for the last couple days. I was sort of able to get the following code to work (in page_load):
But this really isn't a solution, as everything else that gets cached correctly is lost, which leaves me worse off than when I started. Everything else seems to persist fine, it is just the class of the div that is causing me struggles.
Edit: Just wanted to update this for anyone else that comes across this. While I believe there is a solution here with setting the cacheability of the page to force the browser to postback, I could not get it working 100% with all browsers (primarily Firefox was giving me fits, which is a documented bug). I do believe the cookie solution would work, but I felt that may be a bit more complex than necessary for just trying to store the state of a couple div's.
What I ended up doing was tying the div's class to the state of it's correlating radio button (there are radio buttons next to the div which allow the users a more visual way of enabling search panels). I noticed these radio buttons retained the correct checked value when the back button was used, so I could guarantee they would indicate the correct div to be enabled. So in JavaScript's onload I check which radio button is enabled, and then adjust the classes of the search div's accordingly. This is a pretty big hack, but has worked 100% across all browsers, and only took about 10 lines of JavaScript.
I am trying to open a file share link from the window.open ... but its adding the http://localhost/vdir/ before the path can any one say what is the problem?
I have one grid view that contains some template columns. In this, the first column contains check boxes named as Read, fourth and fifth column contains asp:link button. If the user clicks on the read check box, both link buttons should be enabled (Initially it is in disabled mode). I used this JavaScript code for disabling.
function EnablePermissoin(chkB, cellNumber1, cellNumber2) { var IsChecked = chkB.checked; if (IsChecked) { [code]....
I'm trying to enable a button through javascript when a checkbox is checked. This works fine in one of my pages, but on one page the button and checkbox in within a ModalPopup window, and there it doesn't work. How can I work around this?
Im using asp.net c# (webforms) I want to add a back button to my page. (you land on this page if you incorrectly fill in a form). if javascript is enabled i want to go back via javascript, but if it is disabled i'll just do a response.redirect("~/home.aspx"). how can i implement this? is it 2 buttons? how can i hide the other in the 2 different states if so.
so i have a lightbox in which pops up an aspx page with textboxes and two buttons (submit - disabled and cancel - enabled). I wanted to enable my submit button ontextchange. it works fine when opened separately (not as a lightbox) but when i let it run normally with the lightbox function everytime ontextchange gets triggered the whole page refreshes disabling the lightbox.
now if i take out the "autopostback=true" it then will not trigger the the ontextchanged. was wondering if is it better if javascript will be the way to go for enabling the button or is there a way where i can prevent the postback when ontextchanged is triggered?
I've got two linkbuttons on a masterpage. It works fine on all pages apart from page I have a form where if I click on one of the link buttons, then the wrong javascript event is fired. It is firing the button on the form if I click on the button on the masterpage.
In web application, i tried scrolling the window vertically by increasing a y axis height to 500 with a javascript that is attached to OnClientClick event of a asp.net button control with id Button1. The script i have used is
<script language="JavaScript"> function scrollToWindow() { window.scrollTo(0,500); } </script>
and the button code is as follows
<asp:Button ID="Button1" runat="server" Text="Scroll to bottom" OnClientClick="scrollToWindow()" />
If i run this page and click that button, the page scroll is not working properly. when i put alert inside that script and debug, i found that the page is actually scrolling to 0,500 but again its rendering to its normal position because of some reasons. Overcome this issue and let me know the reason behind that?
