I have inline script such as this, which toggles between an edit and a display divs. If it is inside the the UpdatePanel it requires two click before it works. If I remove the UpdatePanel it works fine with a single click.
The first time the page renders the script is executed. If I click the button to cause a postback it doesn't execute again. Is there a way to make it execute the scripts again?
lets say I've got a function that iterates over an array. The function is outside the updatepanel, the array is defined within the update panel. The items of the array are dynamically created. On the first try I've realized, that the values of the array do not update when the update panel loads again.
I cannot determine why this is happening, but I have narrowed it down to the javascript in one of the controls in an updatepanel.
ASP.NET 2.0 aspx structure:
A formview contains a large updatepanel. The updatepanel contains all the controls on the page. Only three controls are autopostback=true: two dropdowns and a checkbox.
The last three controls in the updatepanel are textboxes. Their autopostback=false. Each textbox has an anchor whose javascript launches a pop-up calendar window. The pop-up calendar selection populates the corresponding textbox. No problems there.
The bug happens whenever I fill in all three dates at once (I launch the calendar three times and select a date each time), and then I click Save. The form's save action fails because the code can no longer get to the controls in the formview. The formview.controls.count is zero.
It works if I fill in any two of the three dates *or* I fill in all three dates by typing the values into the textboxes (bypassing the pop-up calendar). I can fill them in random order, and any one or two are fine, but all three at once triggers the error.
I put the following javascript code inline but it doesn't trigger after the updatepanel is done with its postback:
function EndRequestHandler(sender, args) { alert("this should work"); } Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
Before I start to write my problem, I will excuse for my bad English and I hope you can understand me. I have in a ASP.NET Webapplication an AJAX Updatepanel. In this Updatepanel is a Textbox for dynamic search results. When I start to write in the Textbox, the results comes like Google suggest. Now, the focus must be always on the Textbox (inputn field), now metter whereto the User clicks. Currently the ASP.NET updatepanel refreshed after a few seconds when the User starts to type.
I have a pop-up CustomControl which I use in a large-scale web application. The pop-up works well everywhere other than when used inside an asp:UpdatePanel, the problem arises when controlling the visibility of the pop-up (the pop-up is nested in a table) with other controls:
When I click the button to open the window I get Error: Object expected and when I try to debug the error with IE 8 JSEditor I get ``Source Code is not available for this location.
I believe that the code of the pop-up is not being initialized completely, but it is just my guess and I don't know how to resolve this issue.
have found many solution for my issue but none doesn't work in my scenario. I have created a test project to demo my concept.Basically, there is a page that host a user control...
[Code]....
WebUserControl1 has a dropdownlist and two other webusercontrols (to be displayed based on the selection of dropdownlist element) inside updatepanel as below.
[Code]....
Code behind file for WebUserControl1 is .....
[Code]....
Now, the problem starts here...There is an external javascript file [JScript1.js] (embedded resource) which basically is used to display an alert box.
[Code]....
WebUserControl2.ascx.cs code behind is
[Code]....
Alert window doesn't get displayed when I change the dropdownlist value. Even the script is getting registered three times (look in the firebug) Need to use ScriptInclude instead of ScriptBlock as the original JS file is too big.
Is it possible to update an UpdatePanel manually using JavaScript or jQuery?
What I have is a TextBox at the top of my page. When a user leaves that TextBox I want to run some server code (it will add a record to my database) then at the bottom of the page I have an UpdatePanel which will get refreshed. The UpdatePanel has a GridView which will have an entry for the record added)
I'm trying to place a user control inside an UpdatePanel.
When the control is displayed, typing inside the TextBoxes has a large delay while in IE (6 & 8). FireFow has an excellent performance. Not only typing, but also scrolling etc experience a large delay up to a few secons.
The usercontrol(s) contain quite a lot of javascript functions that are re-registered using the ScriptManager.RegisterScriptBlock or RegisterStartupScript functions.
why typing becomes so very slow? I believe it has to do something with memory leaking due to the re-registering of the jQuery functions. But I'm unable to find the source of it.
It seems UpdateProgress will be displayed covering the entire area of the UpdatePanel. I want to replicate this behavior using plain javascript, as this behavior needs to be done for a windows client form. Are there any javascript libraries available? I am using a Browser control inside windows client form to get results and render them.
I am trying to register below mentioned javascript for using with GridView to add freeze functioality on GridView. When compiling an error is thrown Microsoft JScript runtime error: 'Sys' is undefined
How it can be fixed.
<script language="javascript" type="text/javascript"> // This Script is used to maintain Grid Scroll on Partial Postback var scrollTop; //Register Begin Request and End Request Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler); Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler); //Get The Div Scroll Position function BeginRequestHandler(sender, args) { var m = document.getElementById('divGrid'); scrollTop=m.scrollTop; } //Set The Div Scroll Position function EndRequestHandler(sender, args) { var m = document.getElementById('divGrid'); m.scrollTop = scrollTop; } </script>
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'
I have a updatepanel which contains of a few dynamically created ImageButtons (the ImageButtons are placed in a panel inside the updatepanel) Since the imagebuttons are children of the updatepanel they automatically triggers a callback to server, fine. But I want the user to be able to cancel the callback after clicking on the imgbutton, preferably through a javascript window.confirm.
I have managed to make it work with a jquery function returning false (i dont know why it works, dont really understand asp.net ajax functionality) but it only works until a callback is done, then I guess I have to rebind the jquery to the controls in the updatepanel or?this turned out to be a jquery question. How do I rebind the recently loaded controls in my updatepanel to my jqyery function? the controls all have the same class and I use that to trigger the jquery function.
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 am trying to add validation on my form. I am using AJAX controls in my form fields. When I remove the Update panel and AJAX control, my validation starts working, but when keeping both the things together, my validation is not working. How could I make them work together?
<script type="text/javascript"> function Validate() { var QuestionTextArea = document.getElementById("ctl00_ctl00_cphBody_midbox_fvInsert_txtQuestion"); varError = ""; if (!IsTextBoxEmpty(QuestionTextArea, " Question Text Area not be Empty.")) { alert(varError); document.getElementById("ctl00_ctl00_cphBody_midbox_fvInsert_txtQuestion").focus(); return false; } return true; } </script> <asp:UpdatePanel ID="UpdatePanel2" runat="server"> <ContentTemplate> <asp:TextBox ID="txtQuestion" runat="server" MaxLength="1000" Columns="50" Rows="5" Style="width: 380px; float: none" Text='<%# Bind("Description") %>' TextMode="MultiLine" /> <AjaxControl:TextBoxWatermarkExtender runat="server" TargetControlID="txtQuestion" WatermarkCssClass="water" WatermarkText="Type your Question Here."> </AjaxControl:TextBoxWatermarkExtender> </ContentTemplate> </asp:UpdatePanel>
When I removes ajax extender and Update Panel. My textbox gets validated and when using UpdatePanel. No javascript function created by me is called.
on my page I have a GridView that displays a bunch of people from different parts of the world. I display their names, email addresses, etc. I also wanted to display the local time of their location but I didn't want this to be a snap shot of the time when the page gets rendered so I decided to use JavaScript to display the time and have the clock keep ticking.
I found a nice jQuery plug-in called jClock which is very simple to use and implement. I simply place a <span class="timeZoneID"></span> and it works like a clock -- except if I place my GridView in an UpdatePanel.
It wasn't working and I kept troubleshooting to no avail. I thought it was the GridView's TemplateField somehow throwing some junk in there. Then I tried removing UpdatePanel and everything started working fine.
Why is UpdatePanel preventing this JavaScript from functioning?
I am using the javascript alert in code behind but after click the Button i trigers the javascript,it's working fine with the update panel but if i using update panel now action work on my program
I wanna assign a JavaScript CallBack function to an UpdatePanel which will be gets called when the UpdatePanel finishes its tasks. After, the UpdatePanel will be sending a string as a result. This JavaScript CallBack function will have to process this resulting string.
I have a piece of inline java script which is within an AJAX updatepanel. The code works perfectly on 1st load but not when the updatepanel is updated.
and then call a JS function. This is because I have more than one update panels and I'll have to write all the condions to check which UpdatePanel was actually called and then do something. Can something be done using Triggers in UpdatePanel. Kindly let me know how this can be done.
It would be great of you could post a sample code too.
In the first Page_Load, I am activating a javascript function to make an ImageButton change between 2 images with an interval.
This works fine.
Now when pressing this imagebutton, the Page_Load event will fire the second time and all this is happening in an updatepanel which means a partial postback.
The question is how to execute the javascript function stopbk() in the Page_Load event in this scenario as I cant just put it in the "Onload". How can I make that work?
