C# - Is There Equivalent Of WPF OriginalSource Event Property In Winform?
Jan 23, 2011
From:
[URL]
The OriginalSource property of the object identifies the original object that received/initiated the event. Consider a custom control (called CustomControl1 in this example) that is composed of a TextBlock. When a MouseDown event is raised on the TextBlock, the OriginalSource property will be the TextBlock, but in CustomControl1's handler, the Source will be changed to the CustomControl1 object so that other elements along the event's route will know that CustomControl1 received a MouseDown.
Is there equivalent of WPF OriginalSource event property in Winform and ASP.NET ? If not how to emulate this ?

The dependency property framework is a general UI Framework that can be needed outside WPF. So is there a way to use it for Winforms or ASP.NET UI for example ?
Update: I mean can I declare a few namespaces and use dependency property framework in winforms and asp.net ?

I created a control where other developers can create an instance and use. There is a button click in the control. How do I allow developers to plug in their own code in a certain part of my control? I am not sure if or how exactly to use a delegate or event in this scenario.
[code].....
How to I update MyControl to allow this?

I've an ASP.NET application running for reporting purposes. This is done for the management. The persons on the production floor have
a windows application running. Some of them needs to view the ASP.NET reporting page. To avoid writing twice the same reporting tools
(ASP.NET and Windows application) I want to import the ASP.Net pages into a windows form. I don't want to have the ASP.NET pages running
outside the windows application.

Situation: I have a web application which shows errors and where you can accept those error messages. I also have a service, which checks errors from a system and sets the error messages in the database. When I accept an error in the web application, i would like the service to know which error message has been accepted, so that it can do some other actions. My guess is that this could be done through some sort of trigger, but i can't figure out how.

Assuming i have a winform that has a button called "Create a Quote". Once user clicks it, a PDF File gets created on desktop. The PDF File has a fixed design/structure e.g. the logo is at the top left corner, the headers are fixed, etc. However, the data it self is pulled from a database.
As you see above, Quotation #, Description, Qty, U.P (USD), T.P (USD) records should be fetched from the db and dumped in the pdf template then create the pdf for user.

I have a web form with two RadioButtons, both use the same GroupName, both have AutoPostback enabled and both have an event handler for CheckChanged. I use tem to show/hide a Panel further down the form which is contained in an UpdatePanel with Conditional Update set and with both CheckedChanged events in the Triggers collection:
[Code]....
Now, the problem arises when I set the Checked property of either RadioButton in Page_Load, which results in the even not firing for the button which was marked as Checked (the event for the radio button whose property was not assigned does get fired). In fact, upon inspecting the source there was no 'onclick' attribute declared for the input element that was marked as checked in the Page_Load, whereas the other RadioButton did have the 'onclick' attribute properly set.
The layout of the form doesn't allow me to place the radio buttons within the UpdatePanel, so that is out of the question. Is the behavior explained above normal? am I missing anything? Both events fire once the assignment to the Checked property is removed from Page_Load.

I've developed a very simple ASP.NET (jQuery) application. The RDBMS is MS Sql Server but I could easily convert it in MS Access. My client would like to have it available on a CD, ready to run. I was thinking to convert it in a WinForm app but, still, I have to install the framework on the client. Is there any other "possible" solution?

I developped a light WinForm Control that run like an ActiveX in a Web Page. No problem yet.However, when i want to access System.IO I got a Security Exception. It seems that I have to sign my assembly, so that's what I did. When my assembly is signed, my Web Browser can't show the Winform. I set IE to download any ActiveX in the Security tab ... Nothing happens. Uncheck "Sign Assembly" ... works fine ...

I wanted to get the total row count in a GridView's databound event handler, so I tried the following:
protected void grid_DataBound(object sender, EventArgs e)
{
GridView grid = (GridView)sender;
DataSet data = grid.DataSource as DataSet;
if (data == null)
return;
int totalRows = data.Tables[0].Rows.Count;
}
The problem is that the grid.DataSource property is null. The DataSourceID property is not null, so does that mean that I can't access the DataSource object in the DataBound event handler unless I assign the DataSource property directly?
Edit1: Here is the code in my GridHelper class for adding rowcount to the BottomPagerRow. I would like to get rid of the requirement to pass in the ObjectDataSource, but can't because I need to use the Selected event to get total row count. Hence the reason for the question. I also think this might be better in a custom control where I can access ViewState, and/or create child controls during the Init event (I still have a problem to resolve with the way the pager renders with an extra cell), but then I'd still have the problem of how to get to the total row count when the DataSource itself doesn't appear to be available in any GridView events.
Edit 2: Not really relevant to the specific problem, but I resolved the problem I was having with the pager rendering so i've updated the code posted. I found the trick here: [URL]
