Hi all!
Heres my problem - i have a gridview bound (via sqldatasource) to a simple table... The table consists of 2 columns, an ID column (auto increment primary key) and a NText column...
On the webpage im displaying the gridview and a simple button. When the user clicks the button a new row is created and inserted... For testing purposes, the NText field just contains a random GUID. The gridview is then rebound and it appears in the list, great, that works fine..... however, when the user clicks the "add random" button i want the row they just created to be selected!!...
so far i've got the ID of the last inserted using the Insert Indentity methodology and returning the ID field. The problem is dont seem to be able to set the SelectedKey or SelectedValue on the datagrid, all i can change is the index!!
What am i missing here??
Cheers!
Will

Perhaps you should try using the selectedIndex property. Both of the SelectedDataKey and SelectedValue are readonly setting them will not affect which line is selected.
Hope that helps.

Hello all,
I'm trying to develop a website that uses a mixed authentication system. In other words, I need to have multiple types of users. Some users will authenticate against the database (external users), while others will need to authenticate against Active Directory. Is there a clean way to do this?

Implementing forms authentication and either using AD or database as appropriate would be the simplest way to go. You could also create a custom HTTPModule that used but that is a little more difficult.

my problem is it always say the "StartAsyncCall" object is undefine..this following is my code. I wonder what i did wrong. I have a button in the aspx page, when click, it will call StartAsuncCall function
[Default.aspx]
[Default.aspx.cs]
public partial class _Default : CodeProject.ScriptPage, ICallbackEventHandler
{
private string text = "Create";
private string xmlString = null;
public string js;
protected void Page_Load(object sender, EventArgs e)
{
js = Page.ClientScript.GetCallbackEventReference(this, "arg", "CallBackReturnFunction", "ctx", true);
StringBuilder newFunction = new StringBuilder();
newFunction.Append("function StartAsyncCall(arg,ctx) { js }");
//Register
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "NewMethod", newFunction.ToString(), true);
}
public void RaiseCallbackEvent(string eventArgument)
{
XMLString = eventArgument;
}
public string GetCallbackResult()
{
return null;
}
public string Text
{
get { return text; }
set { text = value; }
}
public string XMLString
{
get { return xmlString; }
set { xmlString = value; }
}
[my javascipt file]
function XmlWriter()
{
return "testing";
}
function CallBackReturnFunction(arg,context)
{
alert("Got it :");
}

Here is link to a page in a book Ajax with ASP.NET[^] that seems to cover what you are doing.
FYI though, it is very rude to state urgent in your subject line. If you don't understand why read this[^].

I follow that book to do the coding, however, when I try to run it, it said "WebForm_DoCallback()" undefine...I really don't know where did I make mistake. so I wonder can you give me some suggestion?
|
|
|
|
|
The undefined error is javascript, Check to make sure you have defined WebForm_DoCallback() in your javascript code.

Don't put URGENT in your title. It is very annoying and will more likely be ignored by the ones who can answer the question.

In the menu Build/Build Solution compiles your codebehind pages into a dll in the bin folder.

is it only the dll i will upload to teh web server?
What about the Database? I am using sqlserver 2005.

Copy over the bin folder, it will have all of your assemblies in it.
Here is an article covering asp.net deployment. [^]
Regarding the Database, not something I've handled, might try posting on the sql message forum.

As to what files you need to copy, most everything but NOT the .cs, .suo, .sln, .proj, and .resx files

Actually I believe that with VS 2005 you must create a deployment project in order for the DLL to be built otherwise it does runtime compiling and utilizes a temporary DLL with all of the code and returns the ASPX page without.

How do you close an IE Window from server side asp.net script?
I have a page that opens a new window using javascript. The page that is display is an asp.net page. The page has a button that when clicked runs the asp.net onclick event server side.
After validating the data and all is well, I would like to close the window. My solution is to redirect to a page that on the body element has the onload event run the javascript command to close the window. This seems alittle messy and was wondering if there is a better way?

You can register a startup script which will use javascript to close the window.
If you are using .net 2.0 and C# this code would work:
Type cstype = this.GetType();
StringBuilder tmpSB = new StringBuilder();
tmpSB.Append("<script type=text/javascript>");
tmpSB.Append("window.close();");
tmpSB.Append("</script>");
ClientScript.RegisterClientScriptBlock(cstype, "close", tmpSB.ToString());
If you are using .net 1.1 the call is a little different.
Hope that helps.

You can't clode a browser window from server side code, so you have to return a page that contains a Javascript that does it.
You can get rid of the redirect by directly returning a page. Example:
Response.Write("<html><head></head><body><script type=\"text/javascript\">window.close();</script></body></html>");<br />
Response.End();

I have the following code:
IWshRuntimeLibrary.WshNetwork myWSHNet;<br />
myWSHNet=new IWshRuntimeLibrary.WshNetworkClass();<br />
myWSHNet.AddWindowsPrinterConnection(@"\\ZEUS\HEAD013", "", "");<br />
myWSHNet.SetDefaultPrinter(@"\\ZEUS\HEAD013");<br />
I get the WSH Network object fine, and the new printer is created without any problems. What doesn't work is setting it to be the default printer. Anyone any ideas why?

Hello,
Does anybody know of some good (and maybe quite simple  ) tutorials or examples of using ASP.NET 2.0 to make features from social networking sites like MySpace or Facebook? Things like adding/approving friends, joining groups, etc.
If anyone does, I will be very grateful!
Jack.
