Hmm still kind of stumped.

I have

private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{
{
string DesertFile = "Z:\\Tibia Tool\\Quests\\DesertQuest.txt";
rchQuests.LoadFile(DesertFile, RichTextBoxStreamType.PlainText);
}
}

i need it so if Desert is clicked it loads the DesertQuests.txt into the box. Im not sure where im goofing it up

I now have

private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
{

try
{
// Look for a spacific text in the node
if (e.Node.Text.Contains("Desert Quest"))
{
string DesertFile = "Z:\\Tibia Tool\\Quests\\DesertQuest.txt";
rchQuests.LoadFile(DesertFile, RichTextBoxStreamType.PlainText);
}
}
// If the file is not found, inform the user.
catch
{
MessageBox.Show("File not found.");
}

}
the file doesn't load.

Solution 2

Handle the TreeView.NodeMouseClick event and use the e.Node property to select the node.
You can then read the file using File.ReadAllLines and set the TextBox.Lines property.

Even though OP writes "click", it's more likely selection events.

Solution 4

Even though you write "click", most likely you mean handling the node selection events, TreeView.BeforeSelect, TreeView.AfterSelect:
http://msdn.microsoft.com/en-us/library/system.windows.forms.treeview.beforeselect.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.forms.treeview.afterselect.aspx[^].

Besides, from your question it's not clear if you use WPF, Forms or something else. Please tag it, always. The idea is pretty much the same.

Solution 1

To react on an node click, you can use the TreeView.NodeMouseClick Event[^].

So in that event you can check which node was clicked and then if the node is the correct one you can use the RichTextBox.LoadFile Method (String)[^] to fill the rich text box.

Addition:

To identify the node, you can use for example the Text[^] or Tag[^] properties.

The event arguments of the NodeMouseClick include the node that was selected. See: TreeNodeMouseClickEventArgs Class[^]

Addition 2:
Instead of presuming that the file isn't found check what the exception says. So change the code to:

C#

private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
       {
           try
           {
               // Look for a  spacific text in the node
               if (e.Node.Text.Contains("Desert Quest"))
               {
                   string DesertFile = "Z:\\Tibia Tool\\Quests\\DesertQuest.txt";
                   rchQuests.LoadFile(DesertFile, RichTextBoxStreamType.PlainText);
               }
           }
           } catch (System.IO.FileNotFoundException) {
              MessageBox.Show("File not found");
           }
           catch (System.Exception exception)
           {
              MessageBox.Show(exception.Message);
           }
       }

That would give you the exact details also if the exception is something else than file not found.

Quite possible, but the examples OP has now refer to node click. Not sure about it though...

athenso 16-May-12 14:40pm

So the code doesnt throw errors but it doesnt work either.

athenso 16-May-12 14:44pm

I can have my friends teacher look at it. Like i said the code doesnt throw errors like it was when i was trying it, but it wont load the text file.

Wendelius 16-May-12 14:47pm

If you use the debugger, does the program ever go into loading the file, so is the condition

e.Node.Text.Contains("Desert Quest"))

true? If it isn't, using debugger, check the text of the node. Are there differences in capital letters etc.

athenso 16-May-12 14:54pm

Now i changed it up a tad bit to see if it would work perhaps this way.

if (e.Node.Text.Contains("DesertQuest"))
{
string DesertFile = "Z:\\Tibia Tool\\Quests\\A Pirates Death to Me.txt";
rchQuests.LoadFile(DesertFile, RichTextBoxStreamType.PlainText);
}
else
{
MessageBox.Show("Test");
}

but its still not. I double checked the spelling, the file location (if the file has text (lol) and yes it does).

Wendelius 16-May-12 14:59pm

ANd if you use the debugger id the LoadFile method executed succesfully?

athenso 16-May-12 15:02pm

Yes

Wendelius 16-May-12 15:09pm

That's odd. The only thing that comes in mind is that is rchQuests really the object in your window or is it a text box which is created in the code but not displayd on the screent. You could also check with the debugger does the Text property of rchQuests contain anything after the LoadFile call.

athenso 16-May-12 15:18pm

So if i put it like this

try
{
// Look for a spacific text in the node
if (e.Node.Text.Contains("DesertQuest"))
{
string DesertFile = "Z:\\Tibia Tool\\Quests\\Desert Quest.txt";
richTextBox3.LoadFile(DesertFile, RichTextBoxStreamType.PlainText);
}
else
{
MessageBox.Show("Why is it failing?!?!?");
}
}

If i change the why is it failing to load the document. It works. So it works in the else. Maybe im declairing it wrong? Any thoughts? Because now with the else there it works but it does the messagebox.show in the else statment

Wendelius 16-May-12 15:22pm

Do you mean that with this code it always goes to the else section? If that's the case then the node text doesn't contain "DesertQuest". Based on the picture you posted I thing the condition should be:

if (e.Node.Text == "Desert Quest")

athenso 16-May-12 15:22pm

It works now. Thanks much!

Wendelius 16-May-12 15:23pm

Glad to hear it got solved :)
