Logic Question about Public Method I created.

[SouthSpawn]

I have the following situation.

I am creating my own user control.
This asp.net user control will have a method called "Read". When this
method is being called from the page. It will read line by line threw a
list dictionary. While reading line by line
it will be setting public properties that my page can access. So my user
control will look like this.

Usercontrol.ascx

public class clsUserControl
{
private string strMyPropertyValue;

public bool Read()
{
foreach(ListDictionary MyListRow in MyListDictionary)
{
strMyPropertyValue = (string)MyListRow.Value;
}
}

public string MyReturnedValue
{
set
{
MyReturnedValue = strMyPropertyValue;
}
}
}

Now, my webpage called webpage.aspx.
Will do the following.

public class clsMyWebPage
{
//This will reference my usercontrol on the webpage.
protected clsUserControl MyUserControl;

private void DoSomething()
{
string strGetValue;
while(MyUserControl.Read())
{
strGetValue = MyUserControl.MyReturnedValue;
}
}
}

My question is this. How do I get my ".Read" method to loop through each
row setting the public property for each new value it retrieves
from the ListDictionary? Also, meanwhile setting the .Read method to
"true" so the calling page while loop will keep looping? I hope this makes
sense.

Thanks,
Mark

Hello SouthSpawn,

Perhaps you are interested in doing something along the lines of an event...

public delegate void MyPropertyValueReceivedHandler(string value);

public class clsUserControl
{
public event MyProertyValueReceivedHandler MyPropertyValueReceived;

public void Read()
{
foreach(ListDictionary MyListRow in MyListDictionary)
{
if (MyPropertyValueReceived != null)
{
MyPropertyValueReceived((string)MyListRow.Value);
}
}
}
}

Your calling code then only wires up its interest in the MyPropertyValueReceived
event and does what it needs to...

public class clsMyWebPage
{
protected clsUserControl MyUserControl;

private void DoSomething()
{
MyUserControl.MyPropertyValueReceived += new MyPropertyValueReceivedHandler(HandleProperty);
MyUserControl.Read();
}

private void HandleProperty(string s)
{
// do something...
}
}

You can get more information about events by googling C# events.
