checkbox CheckedChanged event not firing after conversion to .net 3.5

I have a gridview that is in a webpart, , one column is a checkbox column.
in the grid_row created event I set the proberties for the check box like so:

    private void Grid_RowCreated(object sender, GridViewRowEventArgs args)<br />
		    {   TableCell cell;<br />
			    CheckBoxField column;<br />
			    CheckBox checkBox;<br />
				if (args.Row.RowType == DataControlRowType.DataRow)<br />
			    {   for (int i = 0; i < args.Row.Cells.Count; i++)<br />
				    {   cell = args.Row.Cells[i];<br />
					    column = Grid.Columns[i] as CheckBoxField;<br />
<br />
					    if (column != null)<br />
					    {   foreach (System.Web.UI.Control ctl in cell.Controls)<br />
						    {   checkBox = ctl as CheckBox;<br />
							    if (checkBox != null)<br />
							    {	CaseCategory dataObj = args.Row.DataItem as CaseCategory;<br />
								    if (dataObj != null)<br />
								    {<br />
									    checkBox.ID = dataObj.CategoryId.ToString(System.Globalization.CultureInfo.InvariantCulture);<br />
								    }<br />
								    checkBox.AutoPostBack = true;<br />
									checkBox.EnableViewState = true;<br />
								    checkBox.CheckedChanged +=new EventHandler(checkBox_CheckedChanged);<br />
										    checkBox.Enabled = true;    <br />
	}   }   }   }   }   }

before converting this code worked perfectly, after the event does not get fired. I have removed the scriptmanager and related controls from the page, with no effect.

does anyone have any ideas what is going wrong, or how to fix it?

Hi,

The shipped version of VS2005 did not come with the standard ASP.Net Web Application project template as found in previus versions. In order to have this template included you will need to either install VS2005 SP1, which among other things includes this template. Or you can install just the required components to install this template. See below:

VS2005 SP1 Details:
http://msdn2.microsoft.com/en-gb/vstudio/bb265237.aspx

Components to install template (Need to be installed in this order):
1) http://www.microsoft.com/downloads/details.aspx?familyid=8b05ee00-9554-4733-8725-3ca89dd9bfca&displaylang=en
2) http://download.microsoft.com/download/9/0/6/906064ce-0bd1-4328-af40-49dca1aef87c/WebApplicationProjectSetup.msi

Hope this helps...

how to display a file browser dialog in an ASP.NET user control in design time [modified]

Hello, I have created an ASP.NET web user control which has only one ImageButton. I have added 2 new properties to the class called OnMouseOverImage, OnMouseOutImage, these are both strings with getters and setters. Is it possible to make the designer open the file browser dialog when i click on these properties in the designer? Do I have to add some code, set some properties?..i don't know. I want them to behave like the PostbackURL or NavigateURL or ImageURL in the standard ASP classes for example. If this is possible, then please tell me how. Smile | :)

Uh...isn't there anybody who knows it? i didn't find anything about this problem.

Hi,

You should be able to accomplish this by marking your property with the required Editor attributes. By default all properties appear as straight text editable fields within the designer. By associating your property with an Editor that inherits from UITypeEditor, you should be able to achieve this. For example:

Reference the following namespaces within your class:

using System.ComponentModel;<br />
using System.Windows.Forms.Design;<br />
using System.Design;<br />
using System.Drawing.Design;

Mark your public property with the following:
Editor(typeof(FileNameEditor), typeof(UITypeEditor))

There are a number of pre-built editors that you could utilise so it may be worth having a play and seeing which works best.

do you have to write something like this?

[Editor(typeof(FileNameEditor), typeof(UITypeEditor))]
public string PostbackURL
{
    get
    {
        return ImageButton.PostBackUrl;
    }
    set
    {
        ImageButton.PostBackUrl = value;
    }
}

It doesn't work, probably i'm doing something wrong.

ASP.NET works on the server and sends HTML to the browser. It don't have any access to the printer.

It's java script and won't send print command directly to printer. It will open the print dialog box.

should be able to share it.

I have already read that article but was not sure on a couple of things

What virtual directory do I need to right click on, where is this located?

"To resolve it, Right Click on the virtual directory - select properties and then click on "Create" next to the "Application" Label and the textbox. It will
automatically create the "application" using the virtual directory's name. Now the application can be accessed." -

Hi.

I need to get the user's IP address (C#) of the machine they will be using to access my website.

I tried:
HttpContext.Current.Request.UserHostAddress;
Request.ServerVariables("REMOTE_ADDR");

I do not think I am using it correctly.

Any advice/help will be greatly appreciated.

Thanks
