.net - Finding Control In Winforms Panel?
Jun 3, 2010I need to find a child control in a winforms panel. I was wondering if there is a method similar to Panel.FindControl() of the asp.net webforms panel in the .net winforms version

How can i create a window that holds Patient data in it? The 2 records that you see is in List View. I would then using ContextMenuStrip for text "View Details". When View Details is clicked i need to show the context. For web development this could be done via Javascript,div and panels. How that should be WinForms?
Consider the following code, adding 2 textboxes with the same ID (oops):
protected void Page_Load(object sender, EventArgs e)
{
string TextBoxName = "TextBox1";
Panel p = new Panel();
TextBox t = new TextBox();
t.ID = TextBoxName;
p.Controls.Add(t);
if (p.FindControl(TextBoxName) == null) // <-------*******
{
TextBox t2 = new TextBox();
t2.ID = TextBoxName;
p.Controls.Add(t2);
}
Page.Form.Controls.Add(p);
}
The code is designed to stop adding the same ID twice. However, the Panel.FindControl() method is not finding a control that was added in the previous line of code.
Am I using this in the wrong way?
I mean - sure - I could manually iterate through the controls in the next level, like:
string TextBoxName = "TextBox1";
Panel p = new Panel();
TextBox t = new TextBox();
t.ID = TextBoxName;
p.Controls.Add(t);
TextBox t2 = new TextBox();
t2.ID = TextBoxName;
bool duplicateFound = false;
foreach( Control c in p.Controls )
{
if(c.ID == TextBoxName)
{
duplicateFound = true;
break;
}
}
if( duplicateFound )
{
t2.ID = TextBoxName + "__0";
p.Controls.Add(t2);
}
But I don't understand why this isn't working, whereas Placeholder controls and UserControls work fine.
The reason I am using Panels is for CSS styling. body > div > input - but still - it isn't working.
I need to know whether there will be any problem using win forms control as a custom control in my web app. Problems can be anything related to display, environment where the site is run.
Reason for using is I am not getting the treeview events in web which are there in win app. I need to implement drag drop of treeview nodes to a listbox.

I have an ASP.Net site using Forms authentication. One of the aspx pages loads a WinForms user control hosted in IE. That control must connect with a WCF service located in the same ASP.Net web site.How can I make the WCF service secure? Currently I have set the WCF service to use AspNetCompatibilityRequirements mode but the user control hosted in IE can't connect to the WCF service as it isn't logged in.

Why is there a need to explicitly call GridView.DataBind() to render the gridview. Why wouldn't it render by itself automatically like how it happens in Window Forms?
View 2 RepliesWe have an ASP.net application but some screens are deemed too slow to use by our users.As a result, we are trying to provide a WinForms-based alternative to those data-input centric screens so we can use richer controls like Grids with immediate screen updates and feedback for the user.
Ideally, I would like the users to login to the WinForms application using the same credentials they use in the ASP.net application?
Is it possible?I've found this post ( http://stackoverflow.com/questions/1172069/net-authentication-for-both-web-and-winforms ) but it isn't really answering the question from my point of view... We are not using WebServices, or WCF at the moment and do not plan to use it unless it is really the only way to achieve this.
I work with many diverse technologies, and don't possess the time to evaluate every single UI framework, so I'd appreciate hearing other coders' experiences with various frameworks.
The stuff I've worked with so far (and my perceptions):
WinForms: DevExpress (love the looks, hate the API and bloat), Krypton (free!, looks good, but limited), Telerik (don't like the looks)WPF: have only used WPF Themes pack. Asp.Net: Telerik MVC Controls (love it), jQuery UI (looks great)
I know S#arp architecture is built for ASP.NET MVC. But I'm wondering if it can be used in classic ASP.NET (WebForms) or even desktop applications like WinForms or WPF.

The resource you are looking for does not have a handler associated with it.
in asp.net we can handle the RowDataBound event of the GridView control. this event fires when every row is added to the gridview.
i want to be able to handle this event in the gridview in a winforms application but i cannot find a similar event. my question is what is the event name that allows me to do the same as RowDataBound in asp.net?
