GCanvas | lightweight cross-platform graphics rendering engine | Graphics library

My project is based on WPF. I have created a canvas Container. Under that container, I have two grids (gSettings and gGrid).

I have used GroupBox. Under Canvas Container (gCanvas), I have created two grids (gSettings and gGrid). Under gGrid, I am using Tab Controls (tabCtrlDevice). First time when the Window is loading, it's showing data correctly in both grids, but when I am changing the tab item of tab controls, the second grid i.e. gGrid then, gSettings is disappears.

Please help to sort out this issue.

Thanks in advance.

However, what I'm trying to do is have it so that when i type a team name in it won't return a number, but rather it's respective row on the table. The numbers that are currently called in the function are just placeholders for now. As you can see i tried to call a row at the end of the function using an ID I assigned to the Celtics row but what it returns is [object HTMLTableRowElement]. Any help is appreciated, Thanks!!
