Set values for buttonarray.

[MA]

Hi!

I have this code in a class called activity:

public Button[] getActivity(DateTime startDate, DateTime endDate)
{
TimeSpan ts = endDate-startDate;
int arraySize = ts.Days;
Button[] btnActivity = new Button[arraySize];
return btnActivity;
}

that I call with this:

activity objActivity = new activity();
Button[] btnActivity = objActivity.getActivity(DateTime.Today,
DateTime.Today.AddDays(6));


Is there a way to set for example onClick events, css, button text on each
button in the array before I call it (in getActivity)?

There would be if you were actually creating any buttons, but you're
not - just you're just creating an empty array.

Yes. But can I run thru this array with a loop (for), set all values and
send the array after that?

Hi Marre,

It is a little unclear what you are doing.
For one Button[] btnActivity = new Button[arraySize] will be filled with null references and not really buttons.
You need to initialize new buttons with

for(int i = 0; i < btnActivity.Length; i++)
{
btnActivity = new Button();
}

Then you can loop through the buttons a change the values in a foreach (or set them in the above loop)

foreach(Button b in btnActivity)
{
b.Text = "Click Me";
b.Click += new EventHandler(ActivityButton_Click);
}


Happy coding!

If you run through the array and create the buttons, you can then add
the event handlers to those buttons, yes.

Can I do like this:

public Button[] getActivity(DateTime startDate, DateTime endDate)
{
TimeSpan ts = endDate-startDate;
int arraySize = ts.Days;
Button[] btnActivity = new Button[arraySize];

for(int i=0; i<arraySize; i++)
{
//set all that I want here
}

//and then return the array with all this set
return btnActivity;
}


Ahh....I just try it out

Thanx
