The value of the hidden digit in the GridView cannot be retrieved.

Only the rows originally set by the GridView and the DataGrid are a little different.
The hidden locations of the GridView before the bind data will not be affected by the DataBind ().
So it won't determine any information.
First, you can make all the bitwise parts visible.
Then, in the RowCreated event, use the program token to hide the hidden bit.

1	Public void GridView_OnRowCreated (object sender, GridViewRowEventArgs e)
2	{
3	E. Row [0]. Visible = false;
4	}
	Not clear | print | please refer

Public void GridView_OnRowCreated (object sender, GridViewRowEventArgs e) <br/>{< br/> e. Row [0]. Visible = false; <br/>}< br/>
Because the data generated by the RowCreated event has already been sent to the GridView by bind.
Therefore, you should be able to obtain information
