Query results to table

JamesMitchell4 — Wed, 14 Jun 2017 22:49:07 GMT

Hello,

Please could somebody point me in the direction of an example to show the results of a query task in a table?

I have used the find task example and it is returning results but i dont think they are in the correct format.

I will add further information tomorrow but if there is a sample code somewhere it would be great.

Thank you!

James,

Sure here is a sample that takes the find task sample and makes it work with QueryTask instead:

Thank you so much. This worked!

My next questions are...
How do i change the styling of the table? Font, heading colour, text size, column width etc...

Howe can i make the row selectable so when it is clicked on the colour changes and i can retrieve the value which i will then use for another query allowing the user to zoom to a feature....

Thank you

James,

Well if you have started with that info I would have given a different sample.

Here is one using dojo dgrid:

Now that you question has been answered twice, be sure to mark this thread as answered and start a new one for further questions.
