Good day Telerik Team,

I've seen your sample demos and forums about saving/loading gridview settings and  it works fine. But your RadGridViewSettings.cs does not support hide columns functionality which i really need to save as part of the gridview setting(s). 

I do need this one, can anyone help me with this functionality or maybe give me sample code(s) for this.  

Hoping for reply
Aubrey :')

Hi aubrey,

You may expose a new property IsVisible for example in the ColumnSettings class and use it for keeping the corresponding property of the columns.

Hi aubrey,

Defining a IsVisible property would be exactly the same as the others in that class:

public class ColumnSetting : PropertySetting
   {
       bool _IsVisible;
       public bool IsVisible
       {
           get
           {
               return _IsVisible;
           }
           set
           {
               _IsVisible= value;
           }
       }      
       }
   }

Setting and getting its value will be again similar to those of the other properties for the column - in the SaveState() method:
foreach (GridViewColumn column in grid.Columns)
                    {
                        if (column is GridViewDataColumn)
                        {
                            GridViewDataColumn dataColumn = (GridViewDataColumn)column;
 
                            ColumnSetting setting = new ColumnSetting();
                            setting.PropertyName = dataColumn.DataMemberBinding.Path.Path;
                            setting.UniqueName = dataColumn.UniqueName;
                            setting.Header = dataColumn.Header;
                            setting.Width = dataColumn.ActualWidth;
                            setting.DisplayIndex = dataColumn.DisplayIndex;
                            setting.IsVisible = dataColumn.IsVisible;
 
                            Settings.ColumnSettings.Add(setting);
                        }
                    }

and LoadState():
column.IsVisible= currentSetting.IsVisible;
 

Best wishes,
Maya
