hey, i'm trying to get Model.Next(), its going ok but how can i check if the node is also visible ? my lucky shot was trying Model.Next().Where("Visible") but it ain't working. anyone can help me please?
I noticed that it was nonsense as soon as I pressed submit but didn't know how to retract it, lack of caffiene I guess. You could do try something like this, not very nice though:
var node = Model.Next(); while (node != null) { if (node.Visible) { break; } node = node.Next(); }
i thought about, but what if the next node is also invisible, then i thought about making a for loop until node is null or visible, but i'm looking for a simpler solution.
In the code above if the next node is invisible it will keep looking until it either finds one that isn't or the finds that the node is null, in which case there isn't one.
Steven your code should work, but I had problems with .Next() not really working for me. Then again I was trying it on DynamicNode.
Anyway I ended up doing it like this. It is quick and dirty but it works.

// return next return siblings[index + 1]; }

private static int GetIndexOf(List<DynamicNode> siblings, DynamicNode current)
{
for (int i = 0; i < siblings.Count; i++)

if (siblings[i].Id == current.Id)
{
return i;
}
}
return -1; // some crazy error!
}
Get Next node where visible
hey, i'm trying to get Model.Next(), its going ok but how can i check if the node is also visible ?
my lucky shot was trying Model.Next().Where("Visible") but it ain't working. anyone can help me please?
Should be about right maybe try flipping the linq so:
Model.Where("Visible").Next()
Or else do:
var items = Model.Children.Where("Visible")
the first line of code doesn't makes any sense to me, the 2nd one just get all the items that are visible. not the next node.
I noticed that it was nonsense as soon as I pressed submit but didn't know how to retract it, lack of caffiene I guess. You could do try something like this, not very nice though:
i thought about, but what if the next node is also invisible, then i thought about making a for loop until node is null or visible, but i'm looking for a simpler solution.
In the code above if the next node is invisible it will keep looking until it either finds one that isn't or the finds that the node is null, in which case there isn't one.
If you find a nicer solution do let me know!
oh somehow i saw "if" instead of a "while" :)
hee hee, early for both of us I guess! Keep me posted.
Cheers,
Steve

Cool, thanks for sharing
thank you both ! i'll go with anthony solution :)
is working on a reply...
