how to hide column on mouse right button click

I need to hide/unhide column on mouse click on menu.

How to do?

In a GridControl or GridDataBoundGrid, you can you code like:

grid.Model.Cols.Hidden[colIndex] = true;

to hide a column.

In a GridGroupingControl, you use code like:

 grid.TableDescriptor.VisibleColumns.Remove("columnName");

Actually i want 2 functionalities hide columns and delete columns from the grid...
User can unhide the earlier hiden column but should not get deleted column back....

How to achieve these 2 functionalities and unhide the column

Hi,

Issue 1: Hide/Unhide the column:

In a GridControl or GridDataBoundGrid, A column can be hidden or unhidden by just setting the this.gridControl1.Cols.Hidden[colIndex] = true;
and this.gridControl1.Cols.Hidden[colIndex] = false; respectively.

In a GridGroupingControl, you use the VisibleColumns property of the GridTableDescriptor to show / hide the columns in the grid. Below is a code snippet

//For hide the "Col0" column
this.grid.TableDescriptor.VisibleColumns.Remove("Col0");

//For show the "Col0" column
this.grid.TableDescriptor.VisibleColumns.Add("Col0");

Issue 2: Remove the column from the grid.

In a GridControl, the column can be removed by calling the gridControl1.Model.Cols.RemoveRange(from,to);

In a GridDataBoundGrid or GridGroupingControl, column can be removed by using the underlying datasource of the grid. Here is a code.

DataTable dt = grid.DataSource as DataTable;
dt.Columns.Remove("Col1");
dt.AcceptChanges();
