Web Forms :: LinkButton Not Causing Validation Inside UpdatePanel (normal Button Does Though)
Jan 30, 2011
I am using a MultiView inside an UpdatePanel with several views within it and a button on each that is supposed to validate the controls on the current view before moving onto the next view in the sequence (a bit like the Wizard control except I wanted more freedom).
I am using an LinkButton but the problem is that the LinkButton is not causing validation -- I have also tested with an ImageButton which isn't causing validation either. However, when I use a normal Button, the validation does work. I have grouped my validation controls into a ValidationGroup and made sure that CausesValidation is turned on.
I have a form that when you click a button, an ajax RadWindow opens with a text box and a button so it can scrape information from another web page. I have set the button that causes the postback to CausesValidation="False", but after it does the postback after loading the scraped information into other controls, it still causes validation to fire.
So, I have a MasterPage, in which I have an ImageButton and an UpdatePanel. Inside the UpdatePanel I have a LinkButton.
[Code]....
As you can see, both components are asociated to the same OnClick event, which should open said PDF document in a new window using javascript (Code Behind of the MasterPage):
[Code]....
I build the path using the toolTip of the component that has been clicked,which has the name of the file that should load in the
new window.
When I run the application, and click the ImageButton, the new window opens and the file loads correctly. However, when I click the LinkButton, nothing happens (it should do exactly the same as the ImageButton).
If I set a breakpoint, and debug, when I click the LinkButton, it goes to the LnkRelease1 event (as it should), everything looks fine, but it doesnt open the new window, It doesn't execute the javascript window.open.
I have a page with two ajax toolkit popupcontrol extenders, both have a Linkbutton inside the popup window, which is inside a panel and updatepanel. The difference is the second one (Linkbutton2) is inside a Gridview, which is also inside a Updatepanel.
The first one works fine, but the second one does not fire when click on it. The code is as follows:
I have a LinkButton inside an UpdatePanel that I do not want the client to click more than once before the UpdatePanel refreshes its contents. Right now the link button initiates a partial postback for every client side click until the update panel has time to refresh. This particular link fires off a very expensive process which I'd rather not have run unnecessarily. Is there a .NET standard way of doing this? Whats a good solution for this?
I have a UpdatePanel which is having a Datalist inside it , and in datalist i have a country dropdownlist whose autopostback = true , now it is causing postback which i want to trigger , but i am unable to set it as AsyncPostBackTrigger inside update panel because update panel won't find the dropdownlist as it is in datalist.
I have put my gridView inside an UpdatePanel with Timer control for auto refresh.The gridView has a linkButton column which is bounded to referenceNo column from database.
On click of this link button i want a panel to get visible. This Panel contains details corresponding to the referenceNo shown in differnt controls (mostly texboxes). Do i necessarily need to put the panel inside the Update Panel.If not how do i do it?
I have tried putting panel outside UpdatePanel, but it doesn't show panel on clicking the linkbutton nor does the values are updated inside this panel (if panel's visibility is set to true by default for testing purpose).
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've an UpdatePanel with a LoginView inside, now, inside the AnonymousTemplate i've a Button (btnLogin), the problem is that the Triggers tag don't see the button. here is the code:
i have two nested gridview inside an update panel. there is a button called btnPhoneEdit inside the child grid view. when the button gets clicked, it do cause partial post back as expected but it fails to invoke btnPhoneEdit_Click.
here is how my grid view looks like and how i add my custom data source to both parent and child grid view. [Code]....
var TargetBaseControl = null; window.onload = function() { try {[code].... //get target base control. w hen i run the page and click the button then no more further processing just button has been click nothing happan......
Buttons inside UpdatePanels are automatically registered as triggers for that UpdatePanel. Is there a way to make the UpdatePanel ignore one of it's inside buttons? That is, to make it so that clicking this button does NOT trigger any sort of postback?
This works fine (when you push enter, another function is called) unless the page has a FormView control on it.
In this case, pushing Enter in the textbox above attempts to validate the form on the page. It will still correctly call the onEnter function, but I need the Enter keypress to not cause Validation of any other forms on this page.
All input fields in the FormView are part of a ValidationGroup, but this doesn't seem to affect anything.
What is the best way to keep the .Net validation from happening when I push Enter in my HTML textbox?
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.
Has anyone encountered while using Context.RewriteUrl in global.asax causes this error: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster ?
Here is the scenario, let's say I have a url
http://mysite.com/admin/login.aspx instead typing the whole url in address, user can type either http://mysite.com/admin/ or http://mysite.com/admin which all end up at http://mysite.com/admin/login.aspx. When a user type http://mysite.com/admin and entered correct login info, and press login button it gets the error above. How can I resolve this? Tried setting EnableValidateRequest to false and EnableViewstateMac to false also even I do not want to use this approach and still does not work.
i have one master page and the ContentPlaceHolder that are inside UpdatePanel. I have too, buttons in master page thad feed the ContentPlaceHolder e update the UpdatePanel.

Obs: I tried sign dynamically the button, but dont works. And when i click on button, the unload method of UserControl begin called.
i have a usercontrol inside an updatepanel. when i click some button this usercontrol will be loaded. and the usercontrol itself has anither button in it. the problem is that the usercontrol code behind is never executed and when the button is clicked the usercontrol disappears.
