Issues loading different shapefiles in given sharp

Question

I am currently working on sharpmap project with the need to work on offline maps. As i am fresher in this field,I am following the sharpmap tutorial and facing a problem with loading new shape files in the given tutorial code.

For Example :\

SharpMap.Layers.VectorLayer("States");
    vlay.DataSource = new SharpMap.Data.Providers.ShapeFile("path_to_data\\states_ugl.shp", true);

At this line of code, if i pass a different shapefile, code builds with a blank background or no display. I have tried with different shape files with different sizes but the result is the same. It only works for the mentioned states_ugl.shp file given in the code. Please need help regarding this issue as I am a fresher in this field.
Thanks.

Try giving layer styling for your layer, something like below.

layer.DataSource = DBlayer;
layer.Style.Fill = new SolidBrush(Color.Transparent);
layer.Style.Outline = new Pen(Color.Black);
layer.Style.EnableOutline = true;
layer.MaxVisible = 13000;
