It's called a property grid. I don't know if it's in the Toolbox by default, but you create objectos of type PropertyGrid. However, it is not as straightforward to use. Look around this site and you'll find great articles on how to use it:
This article, for one, might be of your liking:

Hi,
I'd like to make a cursor jump to the next text field when a user reach to the max length of the other in C# .Net.
Ex: when you enter the key code for software installation, the cursor keeps go to the next text field without using the tab button.
I'm a beginner for VS. Please help thanks.

Step 1. On the form, set the KeyPreview property to true.
Step 2. Make sure that the TabIndex is correct for each TextBox that will have this feature.
Step 3. Add a KeyUp event for each of the TextBox controls. You can make one function, and assign the same function to each of the TextBox controls. Note that in my example, I have have named my function SSNTextBox_KeyUp. In my program, I have three Textbox controls, used for entering a Social Security number.
Step 4. Write the KeyUp event function as follows:
private void SSNTextBox_KeyUp(object sender, System.Windows.Forms.KeyEventArgs e)<br />
{<br />
if (((TextBox)sender).Text.Length == ((TextBox)sender).MaxLength) <br />
{<br />
SendKeys.Send("{TAB}");<br />
}<br />
}
I hope this helps.
Roy.

Hey,
I was wondering if this is a bug or it is supposed to work this way.
Yesterday i was playing with some controls on my windows .NET application.
On one form I have List view Control, but it is disabled. Now eventhough it is disabled it is firig its GetFocus event. I did not understand it. It wasnt firing Click event but just GetFocus and LostFocus. Other controls like textboxes or labels do not fire any events if they are disabled.
It puzzled me...
Thanks

I don't understand the <i>value and innertext </i> property of a XMLNode used in .NET.
Ex:
<xml>
<element>ABC</element>
<element>ABC</element>
</xml>
code:
XmlElement root = doc.DocumentElement;
XmlNodeList nodeList = root.ChildNodes;
Console.Write(nodeList[0].InnerText);
for (int i = 1; i < nodeList.Count; i++)
{
Console.Write(","+nodeList[i].InnerText);
}
nodelist[0].Value = "" => what is nodelist[0].value??
Please explain for me!!!

I'm sure not the expert, but what I found is that ABC is a child of the element node. To retrieve the value I use
val = node.FirstChild.Value;
try that.

Your program works when i run it...
using System;
using System.IO;
using System.Xml;
public class Sample {
public static void Main() {
XmlDocument doc = new XmlDocument();
doc.LoadXml(@"<xml>
<element>ABC</element>
<element>ABC</element>
</xml>");
XmlElement root = doc.DocumentElement;
XmlNodeList nodeList = root.ChildNodes;
Console.Write(nodeList[0].InnerText);
for (int i = 1; i < nodeList.Count; i++)
{
Console.Write(","+nodeList[i].InnerText);
}
Console.ReadLine();
}
}

Hello.
I might be wrong, but InnerText will take all the text inside a node.
for examlple
<xml>
<element1>
<element2>ABC</element2>
</element1>
</xml>
the InnerText of element1 will be "<element2>ABC</element2>"
while value will only fork for childnodes
could this be right ?

That is what InnerXml does. InnerText get the values of the node and all child nodes.
I'm not sure if it ignores white space if the node only contains white space and children. The InnerText of element1 will either be "ABC" or "\r\n ABC\r\n".

Console.Write(".............");
x = Console.Read();
Console.Write(".............");
y = Console.Read();
When using above code, the second Console.Read() has been done automatically caused by the "Enter key" of the first one.
How can I solve this problem? How can I clear buffer of keyboard??
