Hi Deepak, 
 
Thanks for using Syncfusion product.

By default, you can hide the columns by using VisibleColumns property and actual columns are maintaining in Columns(GridColumnDescriptorCollection). So, you can identify those hidden columns by iterating the GridColumnDescriptorCollection. Please refer to the below code example, 
 
Code example 





//To hide the columns 
this.gridGroupingControl1.TableDescriptor.VisibleColumns.Remove("Ship City"); 
this.gridGroupingControl1.TableDescriptor.VisibleColumns.Remove("Ship Country"); 
 
foreach (var column in this.gridGroupingControl1.TableDescriptor.Columns) 
{ 
    //To unhide the columns 
    if (!this.gridGroupingControl1.TableDescriptor.VisibleColumns.Contains(column.Name)) 
        this.gridGroupingControl1.TableDescriptor.VisibleColumns.Add(column.Name); 
} 
  
 
Please refer to the below UG and KB link,

Suggestion2 
If you hide the column by resizing at run time, column width will be getting 0. So, you can find those hidden columns by checking the Column.Width property. Please refer to the below code example, 
 
Code example 





foreach (var column in this.gridGroupingControl1.TableDescriptor.Columns) 
{ 
     if (column.Width == 0) 
        column.Width = this.gridGroupingControl1.TableControl.DefaultColWidth; 
}
