I have 2 link button in my page and every thing was working fine until i added window.onload() method on my page.
After adding window.onload() first link button is working but not the second button. I am using update panel in my page
I have a link button inside a template field of a gridview. The gridview is wrapped in an update panel. I want the link button to fire an async postback but it always fires a full postback. Why is this?
This is a similar problem to the one described in the link below. However, I have tried doing a RegisterAsyncPostbackControl in the gridview databound, but this did not work.

Here is my requirement -
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.
I have a link button with image and label inside it. After postback, the image and label is not visible.
< asp:LinkButton ID="AddNewRunLinkButton" runat="server" CssClass="Navigationlocalnav"
OnClick="AddNewRunLinkButton_Click" >
< img id="Img1" src="../../Images/add_newIcon.gif" runat="server" alt="Add New Run" />
< asp:Label ID="addText" Text=" Add New Run" runat="server">
< /asp:LinkButton>
This link button is used to import/export data. I have added an attribute on click of this link button(AddNewRunLinkButton) to display a progress bar using javascript - SetInterval function. If I remove this attribute, the image and label is getting displayed, otherwise only link button is getting displayed.
AddNewRunLinkButton.attributes.add("onclick","javascript:DisplayProgress()");
function DisplayProgress()
{
timeid = setInterval("addBlock",100)
}
function Addblock()
{
// Display a progress bar as follows - Increase the width of a div tag at this interval
}
I have one TextBox with RequiredFieldValidator control and LinkButton on my page.
May occur the following situation on this page:
I filled the texbox and clicked the linkbutton is make postback on the server - so all ok.When I not filled the textbox and clicked linkbutton it will show message "Please enter your first name." and no postback will happen but when I filled textbox and click linkbutton I got a PROBLEM : Message "Please enter your first name." goes away (correct), but it doesn't preventing posback.
I need to change a standard HTML Input button to a Link button but am running into problems because the existing
code calls a javascript function. The function basically does the same as the browser back button. When I add the code and
set the property runat="server" I get a "CS1026: ) expected".
Quite new to ASP,net (VS2010) so could be going about this the wrong way.

How do I conditionally trigger a full page postback from a link button inside of an update panel?
I have a custom control that contains its own updatepanel with a link button nested inside of it. When the link button is pressed I want its event handler to have the option of either letting the control update as normal or doing a full postback on the page.
Here is the control hierarchy:
Page
Custom Control
UpdatePanel
LinkButton
Event handler Pseudo code:
LinkButton Click Handler Begin
If is a partial post back AND a full postback is needed
Page.DoFullPostback
End If
End Handler
Note: I aways need the partial postback to happen. I was considering injecting a __DoPostback in the controls markup but this seems hacky to me.
how to style/position the pop up that appears when the 'new link' button is clicked. the pop up at the moment is showing at the far right of the screen - nowhere near the editor.
A previous post mentioned that this was a problem with a div with the style of position:relative - I do not have this, so this is not causing the problem.
how to fire a link button event which is there at ajax tab container?
View 1 RepliesI have gone through several posts on this forum about adding a linkbutton to an updatepanel dynamically. A lot of them say just give it a unique ID and some say you have to register add an AsyncPostBackTrigger to the triggers collection. I have tried both and neither work. I have this simple test that I created - the code is below - there is nothing else in this project but the code you see so I know nothing else is interfering with it.
I have also seem people complaining that the linkbutton causes the entire page to postback - in my case nothing happens... I have seen people talk about having to add the triggers on the page init however I can't do that - I am dynamically creating menus based on a selection in a listbox... (not in this simple test but in a larger project) I am using Visual web developer express 2010 if that makes any difference.

I have a main.aspx page, it contains several tabcontainers. In each tab container, there is an iframe with the src="myPage.aspx".
In the myPage.aspx, I have added two comboboxes. The buttons of the comboboxes do now show at all until a postback on the myPage.aspx.
want to do a page refresh when a button inside an update panel is clicked. Is it possible and how?
View 7 RepliesIn my Application I am using one Modal popup extender. I have one Grid View with Item Template containing Link button. I want to set Target Control Id of Popup extender to link Button of the Item Template. As it is inside the Item Template I can not access it directly in the page.
So Is there any alternative to achieve the same functionality.
I've created a dynamic button from another control outside of the update Panel. The button is given an ID and such. When the button is click, a postback occurs and I've re-created this button during Page_Init, Page_PreLoad, and Page_Onload and NONE of them is preserving the value.
The only way for me to find the control was to look at the Page.request.form's allkeys and compare the string with a any text string that contains: Button. Because I ID'd teh button as: ButtonRow_0Col0. But the actual ID is null. However, when traversing through page.request.form, the allkeys shows that ID with no problem.
So how come the actual ID is lost after a partial postback yet, the page.request.form's allkeys can pull out its allkey's value??
