AJAX :: How To Add A Click Event Handler For DataPager Control
Jan 13, 2014
I have got most of this code online, which does not quite work, can something like this be done to produce a button click event to indicate that a built in button on the datapager control has been pressed ?
DataPager Pager1 = ListView1.FindControl("DataPager1") as DataPager;
{
foreach (Control cPagerControls in Pager1.Controls)
{
if (cPagerControls is Button)
{
Button OnClick = cPagerControls as Button;
OnClick += new EventHandler(OnClickMethod());
}
}
}

This event handler is not responding at all to the click event. On click, the pagination numbers disappear and I'm not able to trace it in the debugger because the event handle doesn't even fire so I have no idea what's going on.

I understand I need to load my dynmaic control on every postback and preferrably in Page_Init(). But my dyanmic controls are loaded from a dropdownlist selectedindexchanged event handler. Now after any postback, my dynamic controls are gone. How would I force it to load on every postback ?

I will describe my problem in simple way so it's not exactly what I'm trying to do but the idea is the same.Here is the problem:
I create dynamic buttons from code behind.I get some id from query string,create button with that id ,dynamic add event handler to click event,and add button to placeholder.I store the list of id-s in session and in page load method recreate these buttons and add to placeholder.One of the id-s is CurrentId and it's also stored in session.Buttons click handler do something like this
Button b=(Button)sender; Session["CurrentId"]=Convert.ToInt32(b.ID);
In page load when I create buttons I want to set button text property different from others if id==Convert.ToInt32(Session["CurrentId"]) when list of id-s are gotten from session.But problem is that click event handler is called after page load,and when I create buttons in page load ,CurrentId in session hasn't been channged by click event handler.Can you suggest any solution to this situation?

How can i add a click event to my entire table (not row or cell) that will trigger a server side method and not a JS method.I know i can add attribute which calls JS and then add post back as follows:
table.Attributes.Add("onClick", "return jsFunction(" + 111 + ");");
But, i want to trigger a server side method.
I'm looking for something like we do when adding a clickable event to a control, for example...
lable.Click += new EventHandler(onLabelClick);
And then add
private void onLableClick(object sender, EventArgs e) {//... }

Using vb.net/asp.net 2005.
I have a page books.aspx that has a control named authors.ascx.
Inside the authors control there is a "select" button I want to add some kind of listener or event handler (not sure of the correct terminology) so on the parent page (books.aspx) I can respond to the "select" button being clicked.
I have to pass the authorID from the user control to the parent page.
In my authors.ascx control I just created this event:
[Code]....
Now I need to write the function for SelectAuthorBtnClick and I think add some kind of listener in the parent page to listen and handle the event.

Is there a technical reason for the existence of Page.PreLoad or is this just convenience to have a place where you can neatly place code that always have to be executed before the Load code? Is there a difference between adding code in the PreLoad event handler and adding code at the top of the Load event handler? And what would be a typical scenario where you use PreLoad?

I have a scenario where...
1.) Have created a div with a dropdown list and ok, cancel button
2.) On document ready - registering div created on step 1 into a jQuery dialog
3.) on a javascript button click - I am opening this dialog box.
4.) Now, the problem is - the jQuery dialogbox which I have created, needs to be used by other button clicks as well on same page. Now, my div's (which is a dialog at runtime using jQuery) ok button click is already engaged with a javascript function (button1 click) and I can not associate other button's click events with it - thus stuck up here and have no clues or hit to resolve this.

I've found posts about making a click event with jQuery for a button, however I need a little more then that. When any postback occurs on a page, I need to fire off a jQuery click event. Based on a condition, I want to continue processing (including running the server-side event code after the jQuery code), or, perform a redirect. I'm not quite sure how to go about this.

<asp:DataPager ID="DataPager1" runat="server"
PagedControlID="ListView1">
<Fields>
<asp:NextPreviousPagerField

I would like to call a method and pass a value to it on a link button autogenerated from the database in a templatefield inside a datagrid. I don't know much about delegates
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
..
((LinkButton)e.Row.Cells[(int)eMessage.TitleColumn].FindControl("btnMessageTitle")).Click += new EventHandler(delegate { viewSelectedMessage(this, 35); });
}
void viewSelectedMessage(object sender, int messageID)
{
lblTest.Text = messageID;
}
running the website and viewing the page source, I have realised that there is an OnClick event created for the linkbutton, however, this may be generated anyways. By running my solution using VS debugging, I can see that my method won't fire by clicking any of thos generated linkbuttons.

I am trying to create a custom GridView with a header toolbar at the top that will contain icons to export the grid view to different formats like excel, word, etc.. The problem is, I cannot get the method to fire that is assigned to handle the click event for the corresponding Image Button. The page posts back, but the code I have in the method to handle the click event does not fire. I have followed examples in other posts and from what I can tell I have followed what others have done. Can somebody take a look at see if they can find something that I am doing wrong.

I am creating nested accordion using the object model and have created buttons in the inner accordion's accordion pane. The buttons look great but issue is that the buttons does not fire thier click event. They just do the postback of the page and ignore the event.
I want to show a pop-upextender on the pre_init event but all my panes are added dynamically so it does not give any rows.

I am creating a web control by addin the html in the code behind, like this:
Code:
Dim sb As New StringBuilder
Dim myDiv As HtmlGenericControl = Me.theContainer
sb.Append("<table width='100%' cellpadding='0' cellspacing='0' style='border:0px;'>" & vbCrLf)
sb.Append(" <tr class='mainRow1'>" & vbCrLf)
sb.Append("<td align='left' style='border:0px solid white;'>Main Menu</td>" & vbCrLf)
[Code] ....
This will generate the html for the table in the codebehind then inject it into the specified DIV element. My question is, if I create a control in this manner, how do i add an event that will fire a method in my codebehind? For example, if i want to create a image button i would do it this way in the code:
Code:
<asp:ImageButton CommandArgument='<%# (Container.DataItem.objectValue) %>'
ID='ImageButton1' runat='server' OnCommand='Button1_Click' ImageUrl='~/images/folder.gif' />
but in the code behind i would do this:
Code:
sb.Append("<input type='image' name='ctl00$ContentPlaceHolder1$importWizard1$folderControl1$folderRepeater$ctl04$ImageButton" & myCounter & "'")
sb.Append(" id='ctl00_ContentPlaceHolder1_importWizard1_folderControl1_folderRepeater_ctl04_ImageButton" & myCounter & "'")
sb.Append(" src='images/folder.gif' style='border-width:0px;' />" & vbCrLf)
But I cant add the OnCommand because it wont be rendered properly.

I've just taken my first stab at making a ListView, ObjectDataSource, and DataPager run in an AJAX panel.
I had trouble getting it to work until I removed the QueryStringField="page" attribute from the DataPager. This attribute causes the current page to be passed as a query argument in the URL. For obvious reasons, I guess that won't work when posting back using AJAX.
Now my question is if this hurts my SEO. When I used QueryStringField, the page links appeared as regular links with various query arguments. But now the links are just javascript. Haven't I hurt a search engine's ability to scan related pages?

I am wondering how to add a javascript event handler using asp.net ajax. I need to add event handlers after ajax update because Jquery plugin to sort tables doesn't work and the onload method to display a screen keyboard does not trigger as well. Is there a way to do that? Maybe I need to switch to some other ajax library or/and try Asp.Net MVC to accomplish?

I need to run a SELECT box [on]change handler after changing the selectedIndex.
I see the selectBox._events['change'][0].handler() method added by $addHandler, but what is the ASP.NET Ajax way to raise it as an event?
The backup plan is to set sel.onchange directly and skip ASP.NET Ajax events completely.
