Re: Need some help loading a treeview - C# Discussion Boards

10-Dec-08 8:33

I'm still not able to get this going. Because the items are in no specific order I still am getting duplicates.

ne1 have any suggestions???

I have a text string like this coming out of a database....

string nodeText = "name1:name2/name3.name4.name5.name6.name7";

that i want to load into a treeview. The first, second and third item will always be singular (just one on them) but all the other items will have multiple entrys. In a way you can look at it like name 1 and name 2 are the grandfather and grandmother. name 3 is the mother's name, name4 is 1 of her siblings. The sibling (name4) has children etc. This list can go on for generations.
I can parse the string to break the names up but I'm not sure how to recursivly add these to the treeview.

Any help would be greatly appreciated...

You don't need recursion here. Once you have a string array that contains name3, name4, etc, step through them. At each step, search for te node with that name, if it exists, step in, if not, create it.

I am reading a couple of thousand entrys at a time from a database. I'm not adding to an existing tree I am building a new one on the fly.

I was trying to..

once i added name3 i wanted to add all if the name4 items that belonged to it.

Then all the name5's that belong to name4 etc.

I'm thinking recursion is the only efficient way of doing this. But I have been wrong before. Smile | :)

Recursion is a waste of time when you know in advance the number of steps you need to take.

Problem is...I don't know ahead of time the number of steps I need to take.

I am a new to use Chart Control, I have the following two questions:

1: How to select the object such as line in Chart with multiple Series, it seems that Chart Forum also has these questions, but no reply so far, anyone can give one idea for it?

2: It seems current Chart Control can not be used to plot true 3D charts, such as f(x,y,z), am I right? The so called 3D charts in the help files are not true 3D charts, I think.

thanks.

I am also new to the chart control but I have found out that you can have multiple series using the y axis.
If you look at the samples of code that came with the chart control there are many examples of doing what you are talking about.

Have a look at this site and download the samples.

Hi,

the only way I am aware of is through P/Invoke, using

[DllImport("user32.dll")]
public static extern int EnumDisplaySettings (string deviceName,
    int modeNum, ref DEVMODE1 devMode );

I did provide you with some pointers and useful code.

For the details they invented a thing called documentation[^] which google will be happy to locate for you.
