I need the data to be added one after another with an intreval. Using setInterval(), at first the array is completely formed, and only then it is displayed as a whole. What can i do?

while(splitter[current].split(":")[0] != "Q")
	{
		dialogs.add({
			name:  splitter[current].split(":")[0],
			text: splitter[current].split(":")[1] 
		})
		current++;
	}

<ScrollView >
				<StackPanel>
					<Each Items="{dialogs}">
						<Panel  Height="50px">
							<AddingAnimation>
                            	                               <Move RelativeTo="Size" X="1" Duration="0.9" Easing="CircularIn" />
                        	                        </AddingAnimation>
							<Rectangle Color="Red" Opacity="0.5" Layer="Background"/>
							<Text Value="{texts}" TextColor="Black"/>
						</Panel>
					</Each>
				</StackPanel>
			</ScrollView>

You could use setTimeout to call a function recursively after a given delay.

Or look into using FuseJS/Timer.
