Multidimensional textbox?

[Ice725]

Can't seem to get this to work:

 

TextBox[][] txtGames = new TextBox[3][5];

 

Is it possible to do multidimensional arrays with TextBoxes?

[Bucky]

Using [][] does not define a multidimensional array; it defines a jagged array. Perhaps

the syntax you're looking for is:

 

TextBox[,] txtGames = new TextBox[3,5];

Works great. Thanks

Is there an easy way to add a TextChanged Event for all the first dimension in the array?

 

For instance, I'd like to update lblSeries[0] by adding the following at runtime:

txtGames[0,0] txtGames[0,1] txtGames[0,2]

 

same with lblSeries[1], would be updated when any of the following text values are changed:

txtGames[1,0] txtGames[1,1] txtGames[1,2]

 

Any ideas?

Use a for loop and add the handler in it.

[Ice725]

Never hard-coded handlers before. I tried this, but it gives me an error saying I'm missing a ' ) expected

 

for (int x = 0; x < 3; x++)
    this.txtGame[x,0].Leave += new System.EventHandler(this.txtGame[x,0]_Leave);

 

How should my Method look?

[Bucky]

You can't change the name of all the event handlers you're adding; they have to all

be the same method. This is okay, because you can discern between which TextBox

is firing the event by casting the sender object to a TextBox and retrieving its name.

 

So, here's what your loop should look like:

for (int x = 0; x < 3; x++)
   this.txtGame[x,0].Leave += new System.EventHandler(this.txtGame_Leave);

 

And here's your event handler:

private void txtGame_Leave(object sender, EventArgs e) {
   TextBox txt = (TextBox)sender;
   // Now just check the value of txt.Name to determine which textbox fired the event
}

 

You could consider setting each TextBox's Tag property to reflect the index of that

TextBox within the array; that way, in the event handler, you can just retrieve the

Tag to figure out which TextBox activated the event.
