[Solved] How to enable sorting / filter on custom GridViewColumn

[Jeffery]

I am trying to create cutom gridview column, like this:

    public class MyDataColumn : GridViewDataColumn
    {
        public override FrameworkElement CreateCellElement(GridViewCell cell, object dataItem)
        {
            var presenter = new TextBlock();

            var opp = dataItem as TestData;
            if (opp == null) return presenter;

            // Do something here ...

            return presenter;
        }
    }

I am able to add the column to grid before set ItemSource:

            Grid1.Columns.Add(new MyDataColumn
                                  {
                                      Header = "My Data Column",
                                      IsReadOnly = true,
                                      IsSortable = true,
                                      IsFilterable = true
                                  });

 

 

The column looks fine.  However, sorting and filter are not there for the column.  What should I do to enable them?  Also, what should I do to support export for the custom column?

Thanks in advance.

P.S. I have create a sample project for this.  Unfortunately, I could not attach a zip file with this post.  If you need it to understand what I am trying to achive here, I can eamil it to you.

Hi,

You need to set DataMemberBinding if you want sorting, filtering, grouping, etc.

Thanks for the quick replay.

However, I could not really do / do not really know how to do that.  The actual data shown in the cell is not in the ItemSource for the GridView.  I use a converter to set the content.  The code I have is quite like what mentioned in this post: http://www.telerik.com/community/forums/wpf/gridview/calculated-columns.aspx.

Could you please give me some idea?

Thanks.

Hi,

If you want dynamic objects binding you can check my DataTable for more info.
