AJAX :: Javascript Change-state Toggle Button Inside An Updatepanel?
Oct 7, 2010
I've got a rather difficult one here. I have a JavaScript jquery toggle button inside an update panel. Right now i'm using <form body="onload"> to recall this javascript to re-apply the button state after each partial postback. It works, but it requires two clicks sometimes.
The problem is... after a few clicks, it is significantly slowing down the PC, and I can see the clicks trailing half a second to nearly a second. If I have a group of buttons, all those click events are just catching up to my clicks. It is rather amusing but I suppose it has to do with the fact that the postback is calling the <body onload=" event> each time after the button is clicked.
lets say you have the toggle buttons from this page: [URL]
and you put it in a UpdatePanel AJAX... so lets say on a partialpostback.. when you re-create teh controls on server-side, the state of whether or not those buttons were pushed is long-lost and gone.. so how then how do you remember those states?
Can I save each button state into viewstate or session state? regenerate each button then call the javascript function to change its color-state depending on the session state variable?
I have a rquirement thay in grdivew need to show the 2 custom ads and 3 google ads, so i have written an user control and inside that using the adsense script, and binding the gridview manually with 2 custom ads and then calling the user control with few functionality. But i have used ajax to ignore the post back So while clikging on paging the google ads are not loading as they are loading from javascript.I came to know that we cannot call javascript inside updaetpanel means Ajax, this is an urgent requirement for me,
I don't understand what the problem is with this. It should be a simple operation yet it doesn't work.
I found samples on how to do this, when I apply the sample, it doesn't work.
In my page I have this:
[code]....
When I run the page, after 5 seconds it switches from the first image to the second image and never switches back to the first image.
When I debug with a break in the code-behind, it looks like the timer ticks twice for every tick. So, when the image is sample2, it then changes back to sample1 and then immediately ticks again and switches back to sample2 with no update-panel refresh in between.
I have an updatepanel and in my updatepanel I have an button. OnClientClick property that; OnClientClick="return confirm('Can you delete this data?');return false;"
when I keystroke on enter key, button clientclick is work and there occur warning on my page .
I am having trouble with getting the Jscroller2 too work inside an updatepanel after I have added a marquee as a newsbanner. - (The marquee is running outside the updatepanel)Beforer the marquee was present I could trigger the JavaScript with:
[Code]....
Now the Jscroller2 only works when the page is loading the first time and not after the updatepanel has updated.So my question is how do I get the Javascript to fire after the updatepanel have updated when a marquee is present?
I have a asp.net listbox server control that is connected to a jquery plugin that can handle a client side click event for each of the checkboxes it renders.
Whenever I click on a checkbox the click event gets triggered and I make a call to
__doPostBack("UpdatePanel1", ""); so that i can update the updatepanel and rebind the checkboxlist inside it.
is it possible to do the rebind first, and then update the updatepanel? how do i do that? because now, the rebind happens on the second time i click on the checkbox.
I've a dropdown and a listview inside an updatepanel (Master/Child relationship) so based on value selected in dropdown the listview gets populated. The Listview allow user to perform Edit/Insert/delete of records. I have to implement a scenario when a user is editing/inserting a record and if he tries to navigate away/change the value in dropdown he should be prompted to save the data and if he choose yes in JS Confirm Dialogue then the currently edited/inserting record should be saved (for which i'm trying to mimic the click of the update/insert button using js). I've attached change eventhandler of dropdown using JQuery which is getting called properly bind. [Code]....
This code gets bind using Sys.Application.add_load(saveChanges); I also tried the following Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(saveChanges);Sys.WebForms.PageRequestManager.getInstance().add_endRequest(saveChanges). The eventhandler gets called correctly but the click() doesn't work! Also the reason I'm calling click() method of button is to perform the validations via RequireValidator/RangeValidators.
I am using UpdatePanel, and I include a gridview inside the updatepanel, I want the grid to be refreshed when button1 or button2 of gridview being pressed. But now when I click the button, the gridview disappeared and look likes the whole aspx is refreshed. I just want to refresh the gridview inside updatepanel. But now the gridview is disappeared. The following is
I have an update panel which is inside a Modal Popup Extender. When I click the Refresh Report button it always calls a postback. I need to stop it from posting back.
I'm using a searchoption on my website. (language = VB)
The user can choose a searchcriteria out of a dropdownlist (Artist name, Description, Price, Genre, Type) . If the user selects one of the options in the dropdownlist the correct textboxes are shown.
For example: if the user selects Price he gets two textboxes (one for the min price and one for the max price) if the user selects Artist Name he gets one textbox
The dropdownlist and the textboxes are put into an updatepanel. The searchbutton is outside the updatepanel.
Now for the problem:
If the user doesn't fill in a textbox and presses the searchbutton, the backcolor of that empty textbox should be turned red. The searchbutton is set as a trigger and the panel is updated on the buttonclick, but the colors don't show.
In the clickevent of the button I've said the following code:
If txtCriteria.text = "" then txtCriteria.backcolor = Red Else txtCriteria.backcolor = White End if
Quite a simple piece of code. This works if I remove the updatepanel from my page, but I'd like to keep the updatepanel because it's really nice :p.
In Visual Studio 2008 ,in my application page 'TEST.aspx' have an 'Ajax TabContainer' inside update panel , and Tab Panel "Product Group Identification" containes textboxes ,DropDownlist and button like 'Save' and 'Cancel' , on clcik of 'save' or 'cancel' buttons only dropdownList Disappears for a second and reappears this is due to Update panel.
I'm currently building a simple chat application and I have everything working real smooth except for one thing, and this problem is only in IE as far as I know (in firefox there is no problem).
In my chat application I have the textbox where the user writes the messages to the chat and the button that sends this message togheter in an updatepanel (so that there is no visible postback when pressing the button). I also have in the form tag "defaultbutton=" set to the button. The problem is that when the user uses Internet explorer and presses Enter instead of pressing the button with the mouse that after the 2 first times he/she does this causes the textbox to stop focus on it, which it shouldnt do as in the end of the button the code says it should focus, which works the 2 first times for some reason.heres the code where the problem exists:
aspx:
form id="form1" runat="server" defaultbutton="Button1"> <asp:ScriptManager ID="scriptManager" runat="server">
I have a button that is inside of an updatepanel, I want it so that whenever the user clicks on the button it would update items in the updatepanel and after that it would activate the animationextender but I can't do that as of now because on the button I have OnClientClick="return false;".
i am using vs2008. 1/ i am placed a datagrid control, a textbox and a server side button are inside the CollapsiblePanelExtender.
2/ The collapsible panel Extender placed inside the updatepanel.
3/ outside of updatepanel i have another button("next page") to redirect to next page.
When the page is loading, i am displaying all the records in datagrid. For an example 100 rocords. if i entered some values in textbox and click the button it fetches searching result based on inputs and displaying it in datagrid (for example searched result 20).
Now, I click the button "next page" it redirect to next page. if the user click the browser back button, i need to keep the datagrid to show only searched result. but Instead of that, it displaying all the records(100 records). how to resolve this?
I have a webpage containing a link to open modal popup
In that web page i there is a label where i want to get the value from modal popup.
Suppose in modal popup i have text box and button when i worte any thing in that text box and submitting that text by popup button then entered text will be appear on the label of webpage.
I've got a page with 3 gridviews (well more than 3 but 3 main ones) on it, each includes a template field which uses a ToggleButtonExtender to display images instead of checkboxes. Each one works fine on it's own but if the index is changed on any of the gridviews the images stop displaying on the others
I have a multiview inside an updatepanel. in one of the views, I save a value in a session object like this:
Session["xyz"] = "some string value";
Then I switch to another view and try to pick it up the value in a button's OnClick event:
string x = Session["xyz"].ToString();
But I get a null reference error. Debugging it shows that Session["xyz"] is indeed null, yet other Session variables are still there. Is there something special about Session and AJAX?
I have a dropdownlist, that causes a postback. On the SelectedIndexChanged event, is it possible to force a placeholder that is within a different UpdatePanel to change it's visibility?
For example, when the SelectedItem.Value of DropDownList1 is "1" then show Placeholder1, otherwise hide it.
What I am most interested in is how to configure the UpdatePanels to allow this.
I'm trying to add and edit an image which is located in a detailsview which is inside an UpdatePanel. After I read relevant topics in the forum I installed the Ajax Control Toolkit. Below is my source code. When I used it only for insert new image it worked great. The problem caused when I tried to implement it on the Edit mode, i.e. when I tried to edit the image and upload a different image. Unfortunately it didn't work as I hoped. Nothing happend and the image hasn't been changed. I also tried to change the IDs (AsyncFileUpload ID) to be the same in both places but it didn't work either.
The javascript generated by the asp.net SciptManager control seems to have a bug and cant handle hidden UpdatePanels. A javascript error is thrown when a control within one updated panel tries to make another update panel visible. Is this a bug with ASP.Net ajax? And does anyone have any ideas how to get around this? heres is an example of what im trying to do
this is the javascript error that gets thrown when clicking on the "LinkButton1" link. This error comes from the javascript that is generated by the asp.net ScriptManager control
Error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ContentPlaceHolder1_UpdatePanel2'
