Any Luck With TreeView Control in ASP.NET? Tim Rymer31-Jul-02 8:06 Tim Rymer 31-Jul-02 8:06  Hey, in the Microsoft.Web.UI.WebControls.TreeView Control (which i had to d/l from MSDN), i'm having trouble with the SelectedIndexChanged event which is supposed to go off when a new node is selected. Here's what i've read so far: Dynamically added nodes in Page_Load() won't have events, so just to be safe i create all nodes in the Page_Init(). Any advice other than this will be helpful! ~Timothy T. Rymer Re: Any Luck With TreeView Control in ASP.NET? SEAN MCCOY21-Aug-02 11:00 SEAN MCCOY 21-Aug-02 11:00  Is the AutoPostBack on the control set to True? Re: Any Luck With TreeView Control in ASP.NET? Tim Rymer22-Aug-02 3:51 Tim Rymer 22-Aug-02 3:51  I believe so, but I've had to put that on the backburner for now, i'll be sure to reply here if I start working on it again (which should be soon, i'm finishing up a more important project right now, so i'm sure i'll be stuck in asp.net land soon enough.) ~Timothy T.

Andy Smith31-Jul-02 11:11 Andy Smith 31-Jul-02 11:11  make sure you put the code which sets the focus, at the end of the page, so that the browser runs it after it has already parsed the control you want to affect. Re: ok ... going slightly mad... Chris Maunder31-Jul-02 17:13 Chris Maunder 31-Jul-02 17:13  ...or you can use the <script language=javascript defer> so that the script will run after the page is loaded, or fire the script on the onreadystatechange event cheers, Chris Maunder Re: ok ... going slightly mad...

Todd Smith31-Jul-02 7:09 Todd Smith 31-Jul-02 7:09  I went into IIS and set the directory security (IP address and domain name restrictions) to Denied Access and then added a group of computers using our ip and subnetmask. I also added my own ip as a single computer. When I did this I can no longer open up my project in .NET properly. It says Web Access Failed. Any suggestions? Todd Smith Re: IIS Directory Security? Todd Smith31-Jul-02 7:30 Todd Smith 31-Jul-02 7:30  I figured it out. Apparently IIS is using inverse subnet masking? All the documentation seems to show the other way around. I had to use IP Subnet Mask 24.24.32.0 0.0.0.255 instead of IP Subnet Mask 24.24.32.0 255.255.255.0 which is what all the docs seem to use. Did they change this?

Otherwise you may have to handle the OnDataBind or OnItemCreate and insert the images as neccessary.

Xervanik6-Aug-02 10:46 Xervanik 6-Aug-02 10:46  The session_end event is Notoriously unreliable. The session doesn't officially end some 20 minutes (depending on settings) after the window is closed. And even that's not guarenteed. A possible solution might be to use some javascript with the onunload event in the body tag, but that seems iffy at best too. Sorry I can't be of more help.

I want to add a .txt to the end of a variable so that I can point to it as a file name. namePrefix = "catalog" Filename = join(namePrefix, ".txt") this isn't working so I must not have the correct syntax. If any one knows what it is I'd be very greatful. __________________ Re: Joining text strings in ASP Bullschmidt30-Jul-02 21:17 Bullschmidt 30-Jul-02 21:17  Filename = namePrefix & ".txt" Best regards, J.

Display a message box in an ASP.NET page Naresh Karamchetty30-Jul-02 10:55 Naresh Karamchetty 30-Jul-02 10:55  I am developing an ASP.NET application where a user will enter some infomation in a form, the information will be written to a database, and then I want the application to signal the user that the entry was successful or failed. One way to do this is to have the application display a message box. This is easily done with some client-side script, but I don't know how to do it from the server side. I want the message box to display after some server-side processing has taken place. I know that client-side functions can be associated with controls, but I have found that the client-side function of a control is called before its server-side event handlers. So, is there a way to display a message box from an ASP.NET page? "What would this country be without this great land of ours?" -Ronald Reagan
