Set focus into a listgrid

[phpDave]

Hello Isomorphic.

I know how to set focus to a dynamic form but can not figure out how to set focus into a listgrid. The goal is to set focus to the grid after a search/fetch operation.

By the way I am getting fantastic results using PHP to return JSON sesponses.

Hi Dave,
If you're trying to focus in the ListGrid as part of the callback from a fetch or filter operation, the problem is probably that the operation prompt is still showing when your callback fires -- and you can't focus (or otherwise interact with widgets) while the prompt is up.
You can use delayCall() to delay your focus call and ensure it executes in a separate thread, after the prompt has been cleared.

For example, try modifying the Showcase Application to do a delayed focus as the callback for the filter operation:

    itemList.filterData(findValues, "itemList.delayCall('focus');");

Let us know if this doesn't work for you

Thanks

Thank You Isomorphic.

I still do not understand how to set focus to a grid - say to the
bottom row or top row with a button. (I do understand the delay
issue.)

mylistGrid.focus() ????

Hi Dave
Yes - calling "focus()" on the listGrid gives it keyboard focus. This means that pressing up/down arrow keys on the keyboard will shift the selection within the grid (see arrowKeyAction for more on this.
If you want to "put focus on a specific row", select the row using the listGrid.selection object APIs then call 'myListGrid.focus()' [or to workaround the delay issue 'myListGrid.delayCall("focus");']
