DataTable row count

Hi,

How to count the numbers of rows in a DataTable?

Thanks,

CountRows(datasource)

HI,

I tried that but is says "Invalid Argument type(control)".

[Pripri804]

you have to create a label, and in the text field write the formula

can you post a screenshot ?

I suspect you're getting this error because you're passing the data table name to the CountRows function like so:

CountRows(DataTable1)

The trick is to provide the data source to the CountRows function, rather than the table name. You can find this by viewing the properties of your data table, and going to the Data section.

Hi,

I am using it in an "if" command "if (countrows(datatable2) > 0, navigate(blah), false)"

is this wrong?

Hi Gibert,

Yes, the value that you need to pass to the countrows function is the datasource, not the datatable.

In my example here, the value I would pass to the countrows function is highlighted.

So in your case, it would be:

"if (countrows(datasource) > 0, navigate(blah), false)"

one more question, i put filter on the datatable

Filter(ProjectHistory,Title= DataCardValue9.Text)

how will i use this?

@akosiwong

Try this -

If (Countrows( Filter(ProjectHistory,Title= DataCardValue9.Text) ) > 0, navigate(blah), false)

so basically it will count the rows for the filtered datasource .

I see that you are just checking if the table is empty of not, so you could also use the IsEmpty function.

Hope this helps!
