Capture An Event In A ListView?
Jun 22, 2010
I have a ListView that has a Button in the item template. Is there a way for me to identify which Item had it's button clicked from my OnClick event?
I was able to do it with the code below but it seemed crufty. Is there a better way to do this?
((ListViewDataItem)((Button)sender).Parent.Parent)
UPDATE: Was able to implement using the NamingContainer method that one user suggested and then mysteriously removed his answer. Seems like a safer way to do than my original method:
((ListViewDataItem)((Button)sender).NamingContainer)

i am currently developing an asp.net project. there is a previous, next, and cancel button that the user can utilize, but the problem is that everything is broken into controls so that if they hit the browser's back button it will reset everything and take them to the very beginning. i would like to capture the onbeforeunload event and trigger the previous button click event (i.e. treating navigation like clicking the previous button).

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.

In my gridview when the tab button is pressed the RowDataBound event is fired and I can capture the tab event. But if there is no data in the gridview textbox and tab is pressed, the RowDataBound event is not triggered. Is there a way to capture that event?

I need to capture the 'Update' click event with jQuery in an asp.net GridView and have no way of knowing where to start. I'm still rather new to jQuery. My GridView is attached to a SQLDataSource and, naturally, has all the bells and whistles that that combination affords.

I have a custom hierarchical data source based on the msdn example [URL] An event can be raised in the DataSourceView. If that occurs, I want to display a message on the web page.
The example is that I have a page with a TreeView control which uses a custom hierarchical datasource. If the user selects a node that they are not allowed to select, the underlying datasource will throw and error.
I want to capture this and add a message to the page. The Page_Error event is raised, but there are no eventargs.
Anybody know how to capture such an event?
An alternative approach, although not quite specific enough, is to set a flag during the datasource load event (indicating the datasource is loading) and test for this flag in the Page_Error routine.

I have the following download request in javascript:
var exportWindow = window.open('Download.ashx?source=1', '');
exportWindow.onload = function() {
alert('finished');
};
My problem is that the above alert box does not appear. The download.ashx sets up the following response (which will be saved as a csv file), which works fine.
context.Response.ClearContent();
context.Response.ContentType = "application/text";
context.Response.AddHeader("content-disposition", "attachment; filename="" + fileName + """);
context.Response.Write(resultWriter.ToString());
context.Response.Flush();
context.Response.Close();
If I replace the download.ashx with a normal aspx page, then the alert appears. So my question would be: is it possible to know programatically when the dowload.ashx returned with a response?(using FF3)

I knwo how to capture a line number from en exception error...but I have a need to capture the line number that certain things occur wihtout having excpetion thrown. I guess one way would be to force an exception to occur and then trap the line number but I dont really want to do that because that seems clumsy to me.
What woudl be nice is if there were some way to just say "what line of code is this?" programmatically.
so that regarldess of any code changes when I need that information to be grabbed it alwasy grabs the right value.

I need to achieve an effect of a read-only textbox, where when the user clicks on the textbox a popup grid control appears, after the user has made a row selection the text box is populated.... Looking at the AJAX Toolkit model it seems like a CustomExtender would be the way to go, but I can find no documentation on how to build such a thing, so I am looking at improvising.
Here is my process (which is still not working):
Using either an ASP.NET TextBox or HTML <input type="text" runat="server"> control I need to able to trap on the onclick event and then set an ASP.NET Panel control Visible="true". I have tried placing my GridView control inside a <div> and using style properties to set it to hidden and using a client-side (javascript) event handler on <input type="text"> onclick event setting the style property to visible, this does not work correctly. It results in a empty place-holder like grid that popualtes on click (I suspect this is because the DataGridView lives inside a ASP.NET Panel)
I would like to be able to call a server-side method from inside my client-side JavaScript function. I seem to recall from Microsoft AJAX 1.0 docs a way to RegisterClientScript or some approach that allows this and can not find anything on this being supported with the ControlToolkit/MS AJAX 2. If I can do this I could set my ASP.NET Panel Visible property to true and then call Update() on it's UpdatePanel parent which should give me exactly what I'm looking for.

How can i capture Application pool recycle event in asp.net c# code so that when recycle event occurs i can make a post back or refresh the page in the code ?. Our Application sessionstate mode is StateServer which helps me in not loosing the session data but still i need to refresh the page at server side only on this particluar event.The reason is at the client side javascript webform_DoCallBack doesnot fire when there is application pool recycle and thus website stops getting updates.we have a timer set to 15 minutes when webform_DoCallBack fires and fecthes updates for the page and displays it.

I am developing a web site to display some data that is inside a database. To do this I've created an ASPX web page that opens a connection to a database and retrieves the desired data. After that it populates an asp:table object dynamically.
The problem is that some of the fields that are retrieved from the database are too large to be displayed on the web page, so I decided to make a popup that would be able to display just the desired field.
To do this I've added a button to the asp:table so that when the user clicks it the popup would appear with the contents of the field. However what is happening is that when the user clicks on the button, the page just gets reloaded and the Click event handler is never called.
Below is the code in which I add the button to a TableCell, and the TableCell to the TableRow collection:
[Code]....
note that the popupHandler is a delegate to the function below. I am using it as a the Click event handler for testing purposes.
[Code]....
Also you should be aware that the table is only populated when the user clicks on a "Query" button inside the main ASPX web page, this means that I only populate the table after the PageLoad event has occurred.

I have a gridview that receives data based on selection from a primary dropdownlist object. Works.
Within the gridview, there is a dropdownlist whose selected index is based on the query from the primary dropdownlist. Works.
Problem.
How do I force the used to change whatever value that the dropdownlist contains after they make their initial selection from the primary dropdownlist; except the default value of "make a selection".
Gridview, contains a checkbox which drives whether a selected row is inserted into the data base. The databind in done using an ObjectDataSource on the presentation page, not in the code behind.

Given the following InsertItemTemplate (simplified) I'm not getting anything back in the event object's Values collection.
[code]....
I'm binding the listview to a collection attached to my nHibernate model object (SearchObject.SearchItems). This collection doesn't have insert or update handling like an object datasource would, so I want to handle the insert/update events manually. Is there a way to get these values to come through automatically, or do I have to manually grab each value from its control when I handle this event?
