Hi Raul,
I apologies for the delay in responding to you.
Issue : Hide the first column in GDBG TreeLines Grid
You can achieve this using LayoutColumns() method of the GDBG. The ColumnName specified in the Array String will be displayed in the GDBG. Please refer to the code snippet given below:
this.dgrd.Binder.LayoutColumns(new String[] { "Package_Name", "Check" });
this.dgrd.Refresh();
Also have a look at the modified sample from the below link:
