I am trying to bind generic list to DropDownList an i am not sure how to continue.
here is my code:
protected void Page_Load(object sender, EventArgs e)
{
List<Paths> paths = new List<Paths>();
paths = GetOriginalPaths();
DropDownList1.DataSource = paths;
DropDownList1.DataTextField = "orignalPathName";
DropDownList1.DataValueField = "orignalPathId";
DropDownList1.DataBind();
}
public class Paths
{
public string orignalPathName;
public int orignalPathId;
public string newPathName;
}
public static List<Paths> GetOriginalPaths()
{
return PrepareOriginalPathsData();
}
public static List<Paths> PrepareOriginalPathsData()
{
List<Paths> objPaths = new List<Paths> {
new Paths{orignalPathName = "comp1", orignalPathId= 1} ,
new Paths{orignalPathName = "comp1", orignalPathId= 1} ,
new Paths{orignalPathName = "comp1", orignalPathId= 1} ,
new Paths{orignalPathName = "comp2", orignalPathId= 2} ,
new Paths{orignalPathName = "comp3", orignalPathId= 3} ,
new Paths{orignalPathName = "comp4", orignalPathId= 4}
};
return objPaths;
}
public static List<Paths> GetNewPaths(int orignalPathId)
{
List<Paths> lstNewPaths = new List<Paths>();
Paths objnewPaths = null;
var newPath = (from np in PrepareNewPathsData() where np.orignalPathId == orignalPathId select new { newpathname = np.newPathName, orgId = np.orignalPathId });
foreach (var np in newPath)
{
objnewPaths = new Paths();
objnewPaths.orignalPathId = np.orgId;
objnewPaths.newPathName = np.newpathname;
lstNewPaths.Add(objnewPaths);
}
return lstNewPaths;
}
public static List<Paths> PrepareNewPathsData()
{
List<Paths> objNewPaths = new List<Paths> {
new Paths{newPathName = "part1", orignalPathId= 1} ,
new Paths{newPathName = "part1", orignalPathId= 1} ,
new Paths{newPathName = "part1", orignalPathId= 1} ,
new Paths{newPathName = "part3", orignalPathId= 2} ,
new Paths{newPathName = "part4", orignalPathId= 3} ,
new Paths{newPathName = "part5", orignalPathId= 4} ,
};
return objNewPaths;
}
Fix it!
I had to add this:
public class Paths
{
public string orignalPathName { get; set; }
public int orignalPathId { get; set; }
public string newPathName { get; set; }
}
Your problem might be from the bind prospective you might bind only if not post back!!
If(!Page.IsPostBack)
{
List<Paths> paths = new List<Paths>();
paths = GetOriginalPaths();
DropDownList1.DataSource = paths;
DropDownList1.DataTextField = "orignalPathName";
DropDownList1.DataValueField = "orignalPathId";
DropDownList1.DataBind();
}
What problem are you encountering exactly?
By the way, the DataValueField should be unique. Aas it is it could cause an issue either with the bind, or on post-back.

I have some data in activity which I want to get it in RoutingSlipCompleted consume method. I know we can send data with CompletedWithVariables from a activity to b activity. But I was wondering how it is possible to get data from activity in RoutingSlipCompleted. so this is my activity:
public class CheckInventoryActivity : IActivity<ICheckInventoryRequest, CheckInventoryRequestCompensate>
{
private readonly IInventoryService _inventoryService;
private readonly IEndpointNameFormatter _formatter;
public CheckInventoryActivity(IInventoryService inventoryService, IEndpointNameFormatter formatter)
{
_inventoryService = inventoryService;
_formatter = formatter;
}
public async Task<ExecutionResult> Execute(ExecuteContext<ICheckInventoryRequest> context)
{
CheckInventoryRequest model = new CheckInventoryRequest()
{
PartCode = context.Arguments.PartCode
};
var response = await _inventoryService.CheckInventory(model);
var checkInventoryResponse = new CheckInventoryResponse()
{
PartCode = response.Data.PartCode ?? model.PartCode,
Id = response.Data.Id ?? 0,
InventoryCount = response.Data.InventoryCount ?? 0
};
var checkInventoryCustomActionResult = new CustomActionResult<CheckInventoryResponse>()
{
Data = checkInventoryResponse,
IsSuccess = true,
ResponseDesc = "success",
ResponseType = 0
};
var result = response.IsSuccess;
if (!result)
return context.CompletedWithVariables<CheckInventoryRequestCompensate>(
new
{
Result = result,
LogDate = DateTime.Now,
MethodName = "CheckInventoryActivity",
}, new
{
Result = result,
LogDate = DateTime.Now,
MethodName = "CheckInventoryActivity",
CheckInventoryCustomActionResult = checkInventoryCustomActionResult
});
var queueName = _formatter.ExecuteActivity<CallSuccessActivity, ISuccessRequest>();
var uri = new Uri($"queue:{queueName}");
return context.ReviseItinerary(x => x.AddActivity("CallSuccessActivity", uri, new
{
LogDate = DateTime.Now,
MethodName = "CheckInventoryActivity",
CheckInventoryCustomActionResult = checkInventoryCustomActionResult
}));
}
so by the following line of codes I can get data in CallSuccessActivity:
return context.ReviseItinerary(x => x.AddActivity("CallSuccessActivity", uri, new
{
LogDate = DateTime.Now,
MethodName = "CheckInventoryActivity",
CheckInventoryCustomActionResult = checkInventoryCustomActionResult
}));
}
so I can get this data here:
public class CallSuccessActivity : IExecuteActivity<ISuccessRequest>
{
private readonly IRequestClient<ISuccessRequest> _requestClient;
public CallSuccessActivity(IRequestClient<ISuccessRequest> requestClient)
{
_requestClient = requestClient;
}
public async Task<ExecutionResult> Execute(ExecuteContext<ISuccessRequest> context)
{
var iModel = context.Arguments;
var model = new SuccessRequest()
{
LogDate = iModel.LogDate,
MethodName = iModel.MethodName,
CheckInventoryCustomActionResult = iModel.CheckInventoryCustomActionResult
};
//CustomActionResult< CheckInventoryResponse > CheckInventoryResponse = new ();
var rabbitResult = await _requestClient.GetResponse<CustomActionResult<SuccessResponse>>(model);
return context.Completed();
}
}
I want to get this iModel.CheckInventoryCustomActionResult in RoutingSlipCompleted :
public async Task Consume(ConsumeContext<RoutingSlipCompleted> context)
{
var requestId =
context.Message.GetVariable<Guid?>(nameof(ConsumeContext.RequestId));
var checkInventoryResponseModel = context.Message.Variables["CheckInventoryResponse"];
var responseAddress =
context.Message.GetVariable<Uri>(nameof(ConsumeContext.ResponseAddress));
var request =
context.Message.GetVariable< ICheckInventoryRequest > ("Model");
throw new NotImplementedException();
}
Instead of putting the value into the activity arguments, add it as a variable:
return context.ReviseItinerary(x =>
{
x.AddActivity("CallSuccessActivity", uri, new
{
LogDate = DateTime.Now,
MethodName = "CheckInventoryActivity"
});
x.AddVariable("CheckInventoryCustomActionResult", checkInventoryCustomActionResult);
});
Using xamarin I would like to add a few pins to map to make a route.
My API for adding pins:
{"Id":1,"X":1.0,"Y":2.0,"RouteId":1,"Route":null}
My API for adding routes:
{"Id":1,"Name":"dd","Description":"fff"}
"RouteId:1" is associated with "Id:1"
I would like to create a route by pressing the button(OnNewRouteClicked)
My code:
public partial class CreatorPage : ContentPage
{
private CustomPin pin;
public CreatorPage()
{
InitializeComponent();
customMap.MoveToRegion(MapSpan.FromCenterAndRadius(new Position(53.010281, 18.604922), Distance.FromMiles(1.0)));
}
private void OnClearClicked(object sender, EventArgs e)
{
customMap.Pins.Clear();
customMap.MapElements.Clear();
}
private async void OnMapClicked(object sender, MapClickedEventArgs e)
{
if (String.IsNullOrWhiteSpace(nazwaEntry.Text))
{
await DisplayAlert("Błąd", "Podaj nazwę punktu", "Ok");
return;
}
CustomPin pin = new CustomPin
{
Type = PinType.SavedPin,
Position = new Position(e.Position.Latitude, e.Position.Longitude),
Label = nazwaEntry.Text,
Address = opisEntry.Text,
Name = "Xamarin",
Url = "http://xamarin.com/about/",
Question = zagadkaEntry.Text,
Answer = odpowiedzEntry.Text
};
pin.MarkerClicked += async (s, args) =>
{
args.HideInfoWindow = true;
string pinName = ((CustomPin)s).Label;
// string pytanie = ((CustomPin)s).Question;
string opis = ((CustomPin)s).Address;
// string odpowiedz = ((CustomPin)s).Answer;
await DisplayAlert($"{pinName}", $"{opis}", "Quiz");
// await DisplayAlert("Quiz", $"{pytanie}", "Przejdź do odpowiedzi");
await Navigation.PushAsync(new QuestionPage(new Question()));
};
customMap.CustomPins = new List<CustomPin> { pin };
customMap.Pins.Add(pin);
var json = JsonConvert.SerializeObject(new { X = pin.Position.Latitude, Y = pin.Position.Longitude });
var content = new StringContent(json, Encoding.UTF8, "application/json");
HttpClient client = new HttpClient();
var result = await client.PostAsync("URL to points", content);
if (result.StatusCode == HttpStatusCode.Created)
{
await DisplayAlert("Komunikat", "Dodanie puntku przebiegło pomyślnie", "Anuluj");
}
}
private void OnNewRouteClicked(object sender, EventArgs e)
{
}
}
I wrote an example and hope it will help you. In the OnNewRouteClicked method, get all the points which routeId = 1 and draw a polyline with them:
public partial class MainPage : ContentPage
{
List<Points> myPoints { get; set; }
Routes myRoute { get; set; }
public MainPage()
{
InitializeComponent();
//Some data you get from your apis
myRoute = new Routes() { Id = 1 };
myPoints = new List<Points>();
myPoints.Add(new Points() { Id = 1, X = 55.6666, Y = 66.4444, RouteId = 1 }); ;
myPoints.Add(new Points() { Id = 2, X = 52.6666, Y = 68.4444, RouteId = 1 }); ;
myPoints.Add(new Points() { Id = 3, X = 53.6666, Y = 62.4444, RouteId = 1 }); ;
myPoints.Add(new Points() { Id = 1, X = 55.6666, Y = 61.4444, RouteId = 2 }); ;
myPoints.Add(new Points() { Id = 2, X = 51.6666, Y = 65.4444, RouteId = 2 }); ;
myPoints.Add(new Points() { Id = 4, X = 54.6666, Y = 67.4444, RouteId = 1 }); ;
myPoints.Add(new Points() { Id = 5, X = 59.6666, Y = 69.4444, RouteId = 1 }); ;
}
private void OnNewRouteClicked(object sender, EventArgs e)
{
List<Position> positions = new List<Position>();
//Get all the points which RouteId = 1
foreach (var item in myPoints)
{
Points tempPoint = item as Points;
if (tempPoint.RouteId == myRoute.Id)
{
Position tempPosition = new Position(tempPoint.X,tempPoint.Y);
positions.Add(tempPosition);
}
}
//your map
Map map = new Map
{
// ...
};
// instantiate a polyline
Polyline polyline = new Polyline
{
StrokeColor = Color.Blue,
StrokeWidth = 12,
};
//add your positions to polyline.Geopath
foreach (var item in positions)
{
polyline.Geopath.Add(item);
}
// add the polyline to the map's MapElements collection
map.MapElements.Add(polyline);
}
}

SurfaceSignDBAccess.CreateSigningRequest(Request);
upon calling this function, gives error saying that "use of unassigned local variable 'Request'."
What should be the right way to call this function?
NewSigningRequest Request; - is never initialized in the method, before calling
SurfaceSignDBAccess.CreateSigningRequest(Request);
try this:
var request = new NewSigningRequest();// in the first line of code of the second code snippet.
And in the static method, remove the following code.
Request = new NewSigningRequest();

Now here are my queries:
1.In the aspx page if i try to replace the templateFile with my own template(same as the sample)it gives me an error "Object reference not set to an instance of an object" at this line Where(sh => sh.NonVisualShapeProperties.NonVisualDrawingProperties.Title.Value == "TableHolder") under AddTable.Otherwise it works fine.
2.Also in the second slide i am getting the required table but with the word "image" written 5 times on top of the page.
3.Also in the powerpoint file generated,the template style is not displayed on the slides except the first and the last slide(i.e the slides which are there in the template).
Thank you.
