Hey ... who told you and didn't tell me ... once again I worship at the alter of the StrataFrame Gods.

You know what pisses me off ... I mean really pisses me off ... why does a sh*t product like DNN eclipse our user base in terms of seats ... I just don't freakin' get it.

Yep, Ivan nailed it.  There's 

YourBO.CurrentDatatable.AcceptChanges()

Well, I knock down on weed and another one grows in its place ... the reason I wanted to perform an ID lookup after the initial join was to prevent the slowdown of the query just for looking up the name of the Telemarketer.  So, I created a custom property, gave it a descriptor and bound that column to the XtraGrid.  The data shows up without incident.

However ...

since I'm placing a value into one of the fields of the business object the business object is now "dirty" and it screws up the maintenance form toolbar button states. 

Furthermore, each time the Undo button is pressed all of the Telemarketer names are erased from the column as they are in effect, changes to be rejected from the table.

How does one go about resetting the editing status of that particular field ... or ... keep it from registering a dirty business object altogether.

Thanks,

Yep ... that worked ... it is a good thing this is not 1692 in Winston, Salem ... if it were I'd have all of you burned as witches ... as this worked like magic.

Well ... I hate to be dense in public but would one of you please speak C#?  Here is my custom property ...

        [Browsable(false),
         BusinessFieldDisplayInEditor(),
         Description("DialRecalls.dir_RecallOn"),
         DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
        public DateTime lea_RecallOn
        {
            get
            {
                return (DateTime)this.CurrentRow["lea_RecallOn"];
            }

            set
            {
                this.CurrentRow["lea_RecallOn"] = value;
            }

        }

Hi Charles,

I was working outside yesterday and did not see your post until now.  I also use DevExpress grids a lot and with several Custom Field Properties (which is one of the most useful features of the SF BO).

Follow Ben's recommendation overriding the GetCustomBindablePropertyDescriptors() and you should be good to go.

Howdy CT,

After pounding my head on the desk for a while ... I went down and watched Hardball with Chris Matthews ... and came up with this.

There does not seem to be a performance hit with this solution and it does exactly what I want it to ... I just thought the BBS would be a bit more straight forward. 

The problem it seems is that DevExpress XtraGrid does not care about custom properties ... they don't show up in the designer when populating the grid either ... which is a clue.

This solution takes the lea_id out of the grid, which comes directly from the table and uses that to seek to the primary key of the business object and then pluck the value out of the custom property and push it into the unbound column.


        private void grvLeads_CustomColumnDisplayText(object sender,  DevExpress.XtraGrid.Views.Base.CustomColumnDisplayTextEventArgs e)
        {
            ColumnView view = sender as ColumnView;

            if (e.Column.FieldName == "lea_Phone")
            {
                string phone = (string)view.GetRowCellValue(e.RowHandle, view.Columns["lea_Phone"]);
                e.DisplayText = string.Format("{0###) ###-####}", Convert.ToDouble(phone));
            }

            if (e.Column.FieldName == "lea_RecallOn")
            {
                int leadID = (int)view.GetRowCellValue(e.RowHandle, view.Columns["lea_id"]);
                oLead.SeekToPrimaryKey(leadID);
                e.DisplayText = string.Format("{0:d}",oLead.lea_RecallOn);
            }
        }
