Index of column

[Frank]

Does the IndexOf() method from GridColumnCollection return a zero based index? 

What will be returned if the column wasn´t found?

Thanks,

Frank

 

Remark to: http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/columns/reordering

...

GridColumnCollection cols = grid.MasterTableView.Columns;

GridColumn c = cols.FindByUniqueName(columnName);

if (c != null)

...

 

FindByUniqueName throws a GridException if the column wasn´t found.

So why testing c for null?

 

 

...

Hello Frank,

The GridColumnCollection is a zero-based collection. Thus, the first item in the collection will have 0 as index.

Thank you for noting that the FindByUniqueName() method will throw an exception if the column is not found. In order to avoid the exception you can use the FindByUniqueNameSafe() method.
