Foreach Loop invalidates after screen change

eldorado25 · Post by **eldorado25** » Wed Mar 11, 2020 5:30 pm

I know this is by design,

but is there any work around wherein which I can have it not invalidate itself?

I thought it would be the case of this thread: https://www.ranorex.com/forum/foreach-l ... t6285.html
But I cannot seem to get the Find function working

Any help?

Thanks

Hi,

Could you please post your code, so we can eventually suggest a solution? Usually, it should be enough to simply reset the list, with new instance of looped object. But without seeing exact code, it's impossible to tell what you should do.

Code: Select all

IList<Ranorex.TdTag> AuthCells = repo.LinkedScreens.TableCellInfo.Find<Ranorex.TdTag>("");
			int counter = AuthCells.Count;
			Report.Info("Cells in list " + counter.ToString());
			if(counter>0)
			{
				for(int i = 1; i <=counter; i++)
				{
					AuthCells = repo.LinkedScreens.TableCell.Find<Ranorex.TdTag>();
					foreach(Ranorex.TdTag Cell in AuthCells)
				{
				Validate.Exists(Cell);
				if(Cell.InnerText != null)
				{
					Report.Info(Cell.ToString());
					//Do Stuff (it's basically if contains this, do this, else if contains that, do that)
				}
			}
		}

What I have is a dynamic table that contains a maximum of 3 records based on certain circumstances. Each one of these rows has a view button in a cell next to a Summary cell for that row. When the user clicks on each view button it will take them to a document which needs to be processed by that user, but each one of these has a specific workflow.

What I want to do is access these rows if they exist and carry out the workflow based on the text inside the summary cell, I know a more simple solution exists but this would demand hardcoding some stuff in, which I am not fond of.

Hi,

So if I understand it right, after you "do stuff", the AuthCells is no longer valid, right? In this case, it should be enough to simply refill the AuthCells with new (refreshed) content?...

Code: Select all

IList<Ranorex.TdTag> AuthCells = repo.LinkedScreens.TableCellInfo.Find<Ranorex.TdTag>("");
int counter = AuthCells.Count;
Report.Info("Cells in list " + counter.ToString());
if(counter>0)
{
    for(int i = 1; i <=counter; i++)
    {
        AuthCells = repo.LinkedScreens.TableCell.Find<Ranorex.TdTag>();
        foreach(Ranorex.TdTag Cell in AuthCells)
        {
            Validate.Exists(Cell);
            if(Cell.InnerText != null)
            {
                Report.Info(Cell.ToString());
                //Do Stuff (it's basically if contains this, do this, else if contains that, do that)
                AuthCells = repo.LinkedScreens.TableCell.Find<Ranorex.TdTag>();
            }
        }
    }
}

Hi, no you are not. I found it "the hard way" too in the past
