Forms Data Controls :: LinkButton On Repeater Stops Posting Back After Client Side JavaScript Executes?
Dec 31, 2010
I have a repeater that has a LinkButton in the Item Template. The LinkButton displays a UserControl that consists of a FormView. The UserControl has an HTML Element that when clicked hides the UserControl by simply change the display of the control from 'block' to 'none'. If the 'Close' span is clicked, the UserControl is successfully hidden, but afterward, the 'Edit' linkbuttons no longer postback.
I am trying to find a way in whihc I CAN Move the columns of nested repeaters from one to another. Like I have three caegories of products say A,B,C and I will have X,Y,Z products within each categories and I am trying to find a way of I can find a way that on client side the user can drag items from one category to another like the drag functionality of Ajax control kit ReOrder List.
I am loading an aspx page into a div using jquery.load(). The aspx page loaded into the div has a datalist. Each datalist item has a linkbutton. My problem is that the linkbutton is not causing a postback though. Strangely, if I change the linkbutton to a button, it does postback. Also, when loading the page normally (not from a jquery.load event), the linkbutton performs correctly. What is it that causes the linkbutton to not cause a postback when loaded this way? And is there a better way to handle this?
I am looking for a method to format gridview bound data using javascript.
I know you can have custom formating in Eval using:
[Code]....
But I am looking for a way to perform this task on client side, rather than doing it on the server.
For example if I want to format a date field being bound in a custom way, something like emails date received in gmail. (Only show time if it is today's date [15:30] and only show day and month if it is this year date [14 Jan] and show the full date if it is not this year [10/10/2009].
So, how I use javascript to format a field (ie. custom date format or setting a control visibility)?
I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript"> function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
[code]... Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
I have a list of items on an ASP.net page. That list is selectable in that whenever the user clicks on one, the page does a postback and the server code stores the index or some unique identifier of the picture in a ViewState property indicating that it is currently selected.
I would like to minimize the load on the server and therefore I would like to store the index or unique identifier representing the image in some way on the client side. The best way I can think to do this is to store said information in a hidden field ), however I had two questions about this before I go crazy:
Is this a security risk in any way, shape or form (i.e., exposing implementation details of the page)? Is there a better/best way to do this that is more industry-standard? Does ASP.net provide a framework to do this that is cleaner than my idea? Seems like this would be a fairly common requirement to me...
I have a keyboard-controlled menu which I did with jquery (When I press down, it marks second option and so on...)
But after I select the option I need, I want to click enter to call the button's OnClick method as if the user really clicked it. Which means I have to do a postback.
I have an ASP dropdownlist with AutoPostBack="true" and I want to do some javascript client side which can stop the postback if necessary. However, I can't get it to stop the postback.
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 am using Fabric.Js ... its returning XML file .. i need to save this file. after googling i found that we can save XML files using Activex Control but it will not work other than IE. So i am trying to pass that XML file to server side.. I tried to assign xml data to var and use alert for display its displying all xml File data.. but unable save that file. is it possible to save that xml file to disk or pass that to sever side so that i can save .
I have an asp.net button, that when clicked calls a code behind function. The function does some evaluation, and then I want to call javascript from within this asp.net function.
I basically want to show a dialog box with confirm or cancel options on it.
Confirm should allow the partial postback to take place, cancel should not. I have tried using a trigger and calling __doPostBack() as advised here but it posts back the full page not just the panel.
$('#buttonInUpdatePanel').live('click', function (event) { event.preventDefault(); var item = this; var title = 'Confirm'; var msg = 'Please confirm something'; var $dialog = $("<div id='myDialog'></div>") .html(msg) .dialog({ modal: true, buttons: { "Confirm": function () { $(this).dialog("close"); __doPostBack('Button1', null); //tried this and .submit() on the button //return true; }, "Cancel": function () { $(this).dialog("close"); //return false; } }, title: title }); });
I have changed the doPostBack to use the button ID now and commented out the return true and false lines. When I click the button it calls the confirmation dialog but when you click on confirm it appears to do nothing. I was expecting a call to the method AddExtraVehicle_Click but the breakpoint didn't trigger.
Is there any way to add a confirmation dialog to a submit button when the form already has other validation controls and a summary control using "showmessagebox=true"? I tried adding
OnClientClick="return confirm('Are you sure?');" to the submit button, but that seems to block all of the other validation?
I have a simple question - I use update panel with custom server control inside. I call __doPostBack from javascript and RaisePostBackEvent on the server fires (I implement IPostBackEventHandler).This is client to server call. Could I return data back to the client (after this partial postback)? What is the best way to achieve this?
I have a linkbutton control in gridview. The linkbutton shows multiple names seperated by comma. When i click on names i want to get the nameID which i can pass to sproc. I am not sure how do i bind the name and name ID to the gridview linkbutton?
I need to have a Repeater with the letters of the Alphabet, when the letter is clicked on it returns all the "names" that start with the corresponding letter in a gridview.
I have got a basic repeater below working but when I tried to change it to a LinkButton I seem to have problems with the CommandArgument.
I am very confused about this problem, and i have tried a lot of things to fix it, but for some reason it rejects finding my LinkButton..aspx page:
[Code]....
I have tried the following things and still getting the message the the object reference not set to an instance:
[Code]....
[Code]....
[Code]....
And still it tells me that the object reference is not set to an instance. I find this very strange and hopefully there's someone who can tell me where i make a mistake?
I have Repeater, which consists of LinkButon and Literal. LinkButon and Literal are whole thing by implication. I want get value from Literal, when user click on corresponding LinkButton.
