Hi, I have a map with a few pin of locations :

but the route from 1 location to next location is not showing. I want the map to display like this :

I store the latitude and longitude inside a textbox:
"https://dev.virtualearth.net/REST/v1/Imagery/Map/Road/Routes?wp.0="& Seq1_Lat_1.Text & "," & Seq1_Long_1.Text & ";66;1&wp.1=" & Seq2_Lat_1.Text & "," & Seq2_Long_1.Text & ";66;2&wp.2=" & Seq3_Lat_1.Text & "," & Seq3_Long_1.Text & ";66;3&wp.3=" & Seq4_Lat_1.Text & "," & Seq4_Long_1.Text & ";66;4&wp.4=" & Seq5_Lat_1.Text & "," & Seq5_Long_1.Text & ";66;5&key=" & txtBingMapsKey_2.Text

how can I get the map to show the blue line like in the image 2.

Hi @NurNina ,

Do you mean you only want to show the route between Location1 and location2, show pushpins on other locations?
From the Get Statics Map API of BingMap, we can know that If you want to show route, the parameter should start with wp.n, if you want to show pushpins, the parameter should start with pp.
So, try to modify your URL as below.
"https://dev.virtualearth.net/REST/v1/Imagery/Map/Road/Routes?wp.0="& Seq1_Lat_1.Text & "," & Seq1_Long_1.Text & ";66;1&wp.1=" & Seq2_Lat_1.Text & "," & Seq2_Long_1.Text & ";66;2&pp=" & Seq3_Lat_1.Text & "," & Seq3_Long_1.Text & ";66;3&pp=" & Seq4_Lat_1.Text & "," & Seq4_Long_1.Text & ";66;4&pp=" & Seq5_Lat_1.Text & "," & Seq5_Long_1.Text & ";66;5&key=" & txtBingMapsKey_2.Text
Test Reust:
Hope this helps.

@v-siky-msft I want the blue line of the route to show. But when I put the latitude and longitude inside text label,the blue route line doesn't show. When I put the latitude and longitude straight away inside the link, the blue route line is shown. Why is that?

Hi @NurNina
I made a test just now, and the code can work well.
Please ensure all the Text input box names are correct.

I think mine is not showing because the value inside the textbox does not have double quote. If a textbox has a lookup value, how do I put the value inside a double quote?

Hi @NurNina ,

What does it mean that a textbox has a lookup value?
If the values reference from the Text of Textbox, there is no need to use double quote around them.
Could you share some detailed steps about how do you implement this?

@v-siky-msft what im having right now is :

"https://dev.virtualearth.net/REST/v1/Imagery/Map/Road/Routes?wp.0="& Seq1_Lat.Text & "," & Seq1_Long.Text & ";66;1&wp.1=" & Seq2_Lat.Text & "," & Seq2_Long.Text & ";66;2&wp.2=" & Seq3_Lat.Text & "," & Seq3_Long.Text & ";66;3&wp.3=" & Seq4_Lat.Text & "," & Seq4_Long.Text & ";66;4&wp.4=" & Seq5_Lat.Text & "," & Seq5_Long.Text & ";66;5&key=" & txtBingMapsKey.Text

and the map does not show the route, only the pushpin:

I use lookup function to get the latitude and longitude and put it inside textbox. for example:

Textbox Seq1_Lat :
LookUp(
RouteTables,
RouteID = ddRouteID.Selected.Result && WalkingSequence = "1" && EmployeeID = EmpID.Text,
Latitude_1
)

Textbox Seq1_Long:
LookUp(
RouteTables,
RouteID = ddRouteID.Selected.Result && WalkingSequence = "1" && EmployeeID = EmpID.Text,
Longitude_1
)

Hi @NurNina ,

To debug your issue, please try to create a label and set Text property of label to ImageName.Image to show the Map link URL.
It is easier for us to find out the issue, you can also check to see if there are any differences from hardcoded latitude and longitude links.
Hope this helps.

Hi @NurNina ,

Thanks, I finally reproduce your issue.
You must enter the latitude and longitude of all five waypoints before it shows the route.
As an alternative workaround, I add the condition before each waypoint to check if the text box is blank. Please try this code:

"https://dev.virtualearth.net/REST/v1/Imagery/Map/Road/Routes?"& If(!IsBlank(Seq1_Lat_1.Text)&&!IsBlank(Seq1_Long_1.Text),"wp.0="& Seq1_Lat_1.Text & "," & Seq1_Long_1.Text & ";66;1&") & If(!IsBlank(Seq2_Lat_1.Text)&&!IsBlank(Seq2_Long_1.Text),"wp.1=" & Seq2_Lat_1.Text & "," & Seq2_Long_1.Text & ";66;2&") & If(!IsBlank(Seq3_Lat_1.Text)&&!IsBlank(Seq3_Long_1.Text),"wp.2=" & Seq3_Lat_1.Text & "," & Seq3_Long_1.Text & ";66;3&") & If(!IsBlank(Seq4_Lat_1.Text)&&!IsBlank(Seq4_Long_1.Text),"wp.3=" & Seq4_Lat_1.Text & "," & Seq4_Long_1.Text & ";66;4&") & If(!IsBlank(Seq5_Lat_1.Text)&&!IsBlank(Seq5_Long_1.Text),"wp.4=" & Seq5_Lat_1.Text & "," & Seq5_Long_1.Text & ";66;5&") & "key="&txtBingMapsKey_2.Text
