This problem can be solved by setting the DrawingMarginPercentage property of a layer.
wellsLayer.DrawingMarginPercentage = 50;
As you see, the map is drawn by tile. So there is a possibility that a text is drawing at the edge and part of the text is outside the tile, which will be gone after we clip it. To solve this problem, we can draw larger area than the tile and in this way, we can show the text properly.
Here is a sample how it works. Image 1 and image 2 are 2 tiles next to each other. If there is no margin drawing, the first tile will only get the “Lawr” and the 2nd tile does not have anything related to Lawrence, so the final result you can see is the text being cut. While if we enable the margin drawing, the map will draw a larger tile first (Green Tile) and then cut it to the standard one, so for this case, tile 2 will get “ence” for Lawrence and when merged with Tile 1, the text is complete.
You can also see the larger marginePercentage you set, the fewer possible a text will be cut, and the less performance it will have.
I hope it make sense. And let us know for more queries.
