Increment Number in Power Apps Gallery
Here, we will discuss how to increment a Text Box number values into your Gallery when you click on the “Button” control.
For example, In Power Apps, there are some records in the gallery like Input Details-1, Input Details-2, Input Details-3, Input Details-4, Input Details-5, and so on. Next, When a user deletes one item from the gallery suppose Details-3, the next item will be replaced in the deleted item place.
Refer to the below gif to understand better.
To work around this example, follow the below steps. Such as:
1. Open Power Apps with your respective Microsoft credentials -> Create Power Apps Blank Canvas app -> Select Power Apps Screen -> Insert a Text input control, a Button input [Add] and set Its OnSelect property as:
OnSelect = Collect(
InputCollection,
{
Name: "Input Details-" & CountRows(InputCollection) + 1,
TextBoxValue: txt_IncrementValues
}
)
Where,
- InputCollection = Power Apps collection name
- Name, TextBoxValue = Header of the collection
- CountRows = This function helps to count the total number of items or records in a gallery control.
- txt_IncrementValues = Text input control name

2. Next, insert the Gallery control and apply the collection on its Items property as:
Items = InputCollection

3. Then, within the gallery, insert a Trash icon to help delete the item. Apply the below code on the OnSelect property of the Trash icon:
OnSelect = Remove(
InputCollection,
ThisItem
);
Clear(colIncrementNumber);
ForAll(
InputCollection,
Collect(
colIncrementNumber,
{
Name: "Details-" & CountRows(colIncrementNumber) + 1,
TextBoxValue: txt_IncrementValues
}
)
);
ClearCollect(
InputCollection,
colIncrementNumber
)
Where,
- InputCollection = Power Apps source collection name
- colIncrementNumber = This is a new collection name

4. Once it is done, Save, Publish, and Preview the app. When a user adds any value from the text input control and clicks on the button control, it will increment the number in the gallery control as in the below screenshot.
