There's a surprise. Try a sensible header, they actually work better.

I find it hard to believe that this is super urgent. What do you mean by 'selected' ?

Hi,

What is wrong with the following:

Dim nodesArray() As String
Dim i As Integer = 0

For Each node As RadTreeNode In nodes
nodesArray(i) = node.Value
i = i + 1
Next

I'm trying to populate an array, but I keep on getting the following error:

Object reference not set to an instance of an object.

Please can some one help?

Regards

You have not initialized your array. Try

Dim nodesArray() As New String

VB.NET I don't know. C# you can instantiate array's like

string[] Arr = new string[10];

On Enter move to next field..?

16-Aug-07 1:39

Instead of an array ( which is empty, because you've not called new on it ), try using a List of string. Or just call new on the array, so that it has the space to add the values you're adding.

Of course not. Why do people keep asking questions in this forum and saying 'without using javascript'. You have NO other options on the client side, unless you want to support IE only and use VBScript.

A gridview supports in place adding and editing of rows. Deleting is also easy to add. There are tons of tutorials on the web, there's no way I could explain it as well as an article could, in a forum reply.

Do a postback, and generate your image using GDI+, just draw them based on the values in question. You can then use Response.BinaryWrite to send the image back down, or write it to the local file system and generate an img tag. Or you can just send it as a download.

Hi,

In your web.config add:

<configuration>
<system.web>
<customErrors mode="Off" />
</system.web>
</configuration>

The extra line to web.config i wrote would get you trough this part as then you will see the error occuring.
