Greetings, community. I have encountered a bug with the TextInput control where the OnSelect property doesn't get fired when a user clicks/drags to select text inside of the control before editing. It works fine if a user clicks and then clears/edits text.

Another user reported this issue for data cards in a form previously (OnSelect doesn't fire when highlighting text (powerplatform.com), but I have now identified this is down to the specific controls. In my example, that's the TextInput.

For any Microsoft personnel who see this, I am guessing the issue could be down to a missing EventListener (W3 Schools Link) on the control object in the backend code. I obviously don't know what the code is behind-the-scenes, but I'd guess a mousedown/mouseup event combo is needed. Same for touch movement for mobile interactions.

Glad someone else has found this issue.

Just to specify the problem a bit more for when (or if) a Microsoft person comes to see this: the problem occurs when the user left clicks down within the text input and then moves their cursor outside the bounds of the text input before releasing their left click. 99% of the time this will occur when the user is attempting to highlight text already in the text input to replace it; but, thought I'd highlight this as it is actually possible to have the OnSelect trigger when highlighting the text, as long as you keep the cursor with the text input box when you release left click.

Hi,

It looks like you’re using a Text Input control inside the gallery. If this is correct, please update your collection in the OnSelect property of the Text Input control.

For your reference, check the formula below:

UpdateIf(
MyCollection,
ID = ThisItem.ID, // Condition to match the item in the collection
{
InputValue: TextInput1.Text // Field to update with the new value
}
)
