Web Forms :: Add Event Handler To User Control And Capture Event On Parent Page?
Apr 24, 2010Using 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.
Web Forms :: Firing Click Event On A User-control That Is Created From Another Event?
Mar 1, 2011I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.
Learning The Basics Of Event-driven Programming?
Dec 27, 2010My task for today is to fully understand event-driven programming and how it works. Now there are several ways this can be achieved. The first one is to actually program a basic program that covers the key concepts, and the second approach is to watch a video that explains the key concepts in a way I can understand. Which approach do people recommend?
Does anyone have videos/program demos they found useful and could recommend to me? My major experiences are with ASP.NET MVC, so it would be best if the tutorial were with WebForms ASP.NET.
User Driven Web Query Interface?
May 6, 2010I have several tables in a database (6-7 tables and ~200,000 records, MS SQL) that I'd like users to be able to use a web based query form and return information/datagrid/download csv/excel files. I'd like the user to be able to query the table they want and fields they want, time they want (maybe datepicker)or by selecting a field and perform a GT/LT operation on it. Has anyone done this and if so are there any resources/templates for this type of thing?Here is an example:I have a 'weather' table with 20 variables in it. I'd like a user to be able to select the fields they want to export (radio/check box) by using a date picker A user could select the variable "Temperature" and use GT/LT, etc. some value they enter. in a perfect world, the user could select a checkbox to include all other fields in the output.

View 7 RepliesBuilding User Driven Query Interface?
May 6, 2010I am somewhat of a novice at ASP.NET, but have a lot of database experience. I want to build a web query interface to allow users to get data back from a database. The idea would be to choose various fields (I have about 20+ fields and 200,000 records in the database, and use either the checkbox, listpicker, radio, etc. to select the fields they want). Then the person could search by date, or search by greater than/less than statements in a particular field.
For example: the user could select: Temerature as the variable, and then Greater than and then enter a value and hit submit. I'd like the option to be able to include all the other fields from the table as well (maybe with a check box or something).
User Control To Raise An Event That Is Handled By Another User Control?
Jan 19, 2011Is there any way for one user control to raise an event that is handled by another user control without going through the page? I am using Umbraco and do not have access to the page object.
--Edit--
Umbraco has the idea of Macro's (user controls) that it loads into pages. I can't access the page directly as this is part of the framework.
There is a publish subscribe (pubsub) pattern that I know would fit my needs well (2 user controls that need to talk to each other) but am unsure how to hook it up in ASP.Net without the page object.

Web Forms :: User Control - Run Before Page Load Event?
Mar 3, 2010I have a user control that will basically be a header in most of my pages, but not all.

Is there a way around this?
View 3 RepliesWeb Forms :: Rewiring Up Event Handler Of User Control?
Jul 16, 2010I have a web page where I'm dynamically loading one of a series of user controls. In each user control I call a general-purpose event to inform the web page that data on the user control has changed and/or new data is available. On the user control I define the Event Handler like this: public override event EventHandler DataOut_Handler; and then I force the event to occur like this:
DataOut_Handler(sender, e); On the web page I reload the previously loaded user control and wire up the event handler like this:
protected void Page_Init(object sender, EventArgs e)
{
DataEntryUserControlBase userControl = (DataEntryUserControlBase)LoadUserControl();
if (userControl != null)
userControl.DataOut_Handler += new EventHandler(UserControl_DataOut_Handler);
}
Note: It's "DataEntryUserControlBase" rather than "UserControl" because I constructed an intermediary base class to making casting simpler. Everything seems to work fine but I do have a question: When I step through my code, after the last line in Page_Init is executed I move the mouse cursor over top of userControl.DataOut_Handler but it reads null. The code is working fine but I'm most curious why I don't see any object associated with that item immediately after wiring up the event handler?
