Web Forms :: Pageload Event Not Firing When Gridrow Button Is Clicked Second Time

Jun 11, 2010

Gridrow Button click loads aspx Page1 which is a Modal window(window.showmodaldialog). It has an ascx in it called UC1. In my Page1 following is added.

<head><base target ='_self'/></head>(this was added to solve the problem of losing session data on load of Page1) I cannot do away without this code.

I am assuming this is avoiding Pageload event of Page1 when the same gridrow button, who opens up Page1, is clicked the second time. Please note that after second click I can see the page1 with all it's controls but when I try to debug, I see that it does not raise the page load event the second time. It's as thought the page had been cached or the same frame is gettign loaded.

Problem is I want to raise the Page load event the second time also beacuse my dataload for Page1 happens only on page load. PS: Please note only the second click onwards page load doesn't happen. the first time pagelaod works. If I click a new row's button the first time it works.. later it stops doing a pageload

here is the code for my page

Linkbutton Not Firing RowCommand Gridview UpdatePanel UserControl?

Jun 23, 2010

I have a problem with my Linkbutton which is not firing the RowCommand of my gridview.

Just for an Idea what I am doing is a follows:

1. WebForm

WebForm hosts UserControl_A.

2. UserControl_A = UpdatePanel + Panels + Gridview1 + CollapsiblePanelExtender

Updatepanel of UserControl_A consists of multiple Panels.

Each Panel consists of a Gridview1.

Upon each Panel expand UserControl_B is loaded.

3. UserControl_B = Details View & a couple of Linkbuttons in GridView2

Upon clicking the Linkbutton, unexpectedly it makes a refresh for the entire UserControl_A.

But it does not fire the RowCommand of its parent GridView2.

Forms Data Controls :: RowCommand Not Firing Inside A Gridview ?

Sep 2, 2010

I'm trying to fire the RowCommand event on a DataGrid control. I've previously done that, but not in this precise case.

Actually I'm working on someone else code so I can't really change the structure of his page excepted if it's really necessary.

The code of the page is heavy, so I've summarized the problem in a small project and the page behaves the same way too.

Basically I have a GridView which I bind to a DataSet. According to those data, I sometimes need to add, at the end of a row, a "Details" button (a LinkButton).

By pushing this button, I want to show a second GridView containing those details.

Let's add to this that the columns number of the first GridView is variable, those LinkButton need to be added dynamically.

The first GridView is generated without any problem and when my mouse is over one of the LinkButton, I can see that the link is something like "javascript:__doPostBack('dataGridView$ctl02$lnkDetail','')". When I click on this link and debug step by step : Page_Init, Page_Load, OnPrerender, RowDataBound but no RowCommand, and I don't know why!

In the exemple, I've explicitly set the EnableViewState to true from what I've read here and there, but nothing's changed.

And the code of my .aspx :

AsyncPostBack Firing On Child Textbox Trigger, But TextChanged Event Not Firing?

Jan 22, 2010

I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:

[Code]....

Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.
