I would like to serialize the properties of the HttpBrowserCapibilities object so that it may be returned via a web method call. Currently the object cannot be serialized:Cannot serialize member System.Web.Configuration.HttpCapabilitiesBase.Capabilities of type System.Collections.IDictionary, because it implements IDictionary. ...which is understandable. However, I would like to simply copy out the properties and their values to a hierarchy, i.e.
<HttpBrowserCapabilities>
<IsMobile>true</IsMobile>
</HttpBrowserCapabilities>
I'm starting to think I would need to use reflection to copy this object, but I haven't reached a conclusion. Does anyone have any suggestions to keep this simple?
I am confused about how to reference objects in session, how to update, and copy.
if I create
MyObject obj = new Object ();
then
Session["object"] = obj;
MyObject temp = (MyObject)Session["object"];
If i change something on temp, will the object in session be updated? do i need to follow changes with Session["object"] = temp?
I am building an ASP.NET application that needs dynamic tables. That's another issue that I've already posted about (and gotten a pretty good response!). Now, I'm running into another issue - I want to add new rows to my table, but given that I will have 10-12 tables on one page, each containing different objects in their rows (text boxes, check boxes, etc.) I need a way of simply generically adding a new row that has the same objects as the first row in the table. Here's my code:
Private Sub AddTableRow(ByRef originalTable As System.Web.UI.WebControls.Table)
Dim originalRow As System.Web.UI.WebControls.TableRow = originalTable.Rows(1)
Dim insertingRow As New System.Web.UI.WebControls.TableRow
Dim insertingCells(originalRow.Cells.Count) As System.Web.UI.WebControls.TableCell
Dim index As Integer = 0

View 4 RepliesAm currently working on my first ASP.NET projects. I have a requirement for a page where a user can enter their current address, and then add as many previous addresses as they like. I have created a Panel with the required text boxes in, and also an 'Add' button which will allow them to add another address. How could I make a copy of that Panel and add it to the page at runtime ... assuming that it is possible!!!
View 14 RepliesI followed the instructions from the release notes, except for one thing. I did not include the following in my web.config. Thas the the "bindingRedirect oldversion 1.0.0.0 to newVersion 2.0.0.0". I got an error message to the effect that I could not have 2 configuration sections in the web.config. I was told that as long as I had the system.web.mvc 2.0.0.0 in my BIN and, I was refereincing this same version dll that I should be fine? I am wondering if I should just create a new MVC2 project and copy my MVC1 relevent files into this MVC2 project, not sure.
View 1 Replies I have created a script with pulish to provider button on VS 2010 and I need to deploy my database to my sql server.How can I do that ?
I cannot create a copy of my database on sql server with sql script file.
I have a folder on my server say:
MasterArt
in that folder there is 4 folders
pics
videos
music
other
in the pics folder is jpg's that are the buttons for a web page, the web page is in the MasterArt folder and is named default.aspx upon a user creating an account, i have my program create a folder under a subfolder named ARTIST
I got that part but now what I need to learn how to do is to have at run time, when a new user creates an account, that my program creates a subdirectory under the ARTIST subdirectory and then I copy the default.aspx from the MasterArt folder into their folder, then copy the folders and contents of the 4 subfolders (pics, videos, music, other) so that they now have the direcotries and its contents.
Example: I create a user account and my artist name is Kevin
a subdirectory is created called Kevin, the folder Kevin should now have the default.aspx page, and 4 sub folders, pics, videos, music, and other.
can you please help me to brainstorm the possible causes of this error. I've got a paged repeater with localisation bound programitcally to an sqldatasource using a stored proc.

View 6 RepliesI need to copy a cached treeview control to the treeview control in use.
I know i cannot directly assign the server control to another control.
But, Can anyone come up with a work around to do the same. I dont want to loop through each node of the control and copy it.
i have this method in asp.net for clone my control :
public static Control Clone( Control ctrlSource )
{
Type t = ctrlSource.GetType();
Control ctrlDest = ( Control )t.InvokeMember( "" , BindingFlags.CreateInstance , null , null , null );
foreach( PropertyInfo prop in t.GetProperties() )
{
if( prop.CanWrite )
{
if( prop.Name == "ID" )
{
ctrlDest.ID = ctrlSource.ID + "cloned" + Security.Cryptography.Cryptography.generateRandomPrivateKey( 5 );
}
else
{
prop.SetValue( ctrlDest , prop.GetValue( ctrlSource , null ) , null );
}
}
}
return ctrlDest;
}

I would like to be able to copy one row and five columns from an Excel spreadsheet to a table like structure on a ASP.NET web form. The idea is keeping the data in the exact row and column from Excel to the table like control on the ASP.NET web-form. Then I want to be able to save to the contents of the ASP.NET control to a database by a buttoon command click. What ASP.NET control would allow me to do this? Gridviews and datagrids don't seem to allow me to do this.
