How to select the first item in gallery after filtering the sharepoint list

I have a question, where I have a gallery that is (a filter of) a sharepoint list. When the Gallery's items result is changed after the filter is applied and there are results, I want to "OnSelect" the first result. I haven't found a consistent way to achieve this. It looks like the first item is selected but without triggering the commands in the OnSelect of the gallery ?


Kindest regards,

hi @bouillons im not entirely sure i understand your request but can offer this with an example.


assume you have a combobox that filter a gallery and that gallery filter another gallery. when you filter the fisrt gallery by selecting a new value, the values in the gallery change but they secon gallery still shows the previous selection's results. do get around this you can add to the combobox's OnChange = Reset(Gallery1) this way the gallery is empty and the second gallery is cleared. then when the first gallery is populated the second gallery is filter by the first record.


consider the selection


Without resetting the gallery: (the filter applies the 5 to the first gallery but the second gallery still shows the results of the previous selection, visitor 2)


With the reset of the gallery: (the second gallery goes back to visitor 1 which is the first row)


hope this helps

Thanks, I'll try this. I have a follow-up question: assuming the gallery is loaded already in memory, does the reset cause the data to be refetched from the data source ?

I still don't get the result I wanted. What I want is that whenever the content of the gallery changes, I want the OnSelect of the first item to be executed. So my question is how can I programmatically "click" the gallery's first item in the onchange event of the controls that influence the items selection of the gallery.
