Help! I''m using a GGC and have the grid populated with some rows. I also have the blank "add new row" row at the top (the row with the asterisk). My grid is bound to an IBindingList populated with IEditableObjects. My question is....How do I use the "add new row" row - the asterisk row? How do I validate the user''s entries, move the data down into the grid, etc. Are there any samples available for me to look at? Or similar posts? Or documentation? Thanks, eric

Hi Eric, The add new record row can be set on the top/bottom using the following code. this.gridGroupingControl1.TopLevelGroupOptions.ShowAddNewRecordAfterDetails = true; this.gridGroupingControl1.TopLevelGroupOptions.ShowAddNewRecordBeforeDetails = true; On enter key the data in this row is moved to the grid, also when moving out of this row. To validate, you can try TableControlCurrentCellValidating setting TableCellType as AddNewRecordFieldCell and CurrentRecordContextChange handler. See if this helps Best regards, Stanley

thanks Stanley! A couple more questions for you.... Each of my GGC rows is bound to an object. The object has 6 properties, but only 4 of these properties are visible grid columns, 2 columns/properties are hidden. Of the 4 visible columns, 2 columns are not editable (date/time and user), and 2 are editable. How can I get the 2 non-editable columns to display default values when the user begins typing in the editable fields. I want the date/time column to show the Now() value, and the user field to display a string value. Also, at what point do these 4 column values become an object? I just don''t want the 4 values to move down into the grid, I need to create a new object, add it to the array list, and populate the other 2 non-visible object properties. Thanks! Eric

currently when i type something in the new row and then hit ENTER, the row gets moved to the grid, but when it shows up in the grid the entire row is blank.

Nevermind the part about getting an object added to the array list. I figured that part out. The only thing I need to know now is how to set default values in the empty row. thanks for all of your help!

Yes, thank you, that helped. Actually though, I came across a snipet of code in these forums that you actually suggested which works much better.... private void CurrentRecordContextChange(object sender, CurrentRecordContextChangeEventArgs e) { if(e.Action == CurrentRecordAction.BeginEditComplete && e.Record is GridAddNewRecord) { GridAddNewRecord rec = e.Record as GridAddNewRecord; rec.SetValue("Timestamp", System.DateTime.Now); rec.SetValue("User", "JOHN SMITH"); } }
