GCC set tooltip with cellvalue by a hidden column

[Lorenzo Grassi]

I have a GGC with couple of column, one visible and one hidden. In the hidden column I have a description, and I want to set the tooltip of the visible column with the description taken from the hidden column.

I can set the tooltip on the ActivateToolTip event, but how can I get the value of the adiacent hidden cell?

There is another way to obtain a similar effect?

Thank you

The grid has support for cell tips through its GridTableZCellStyleInfo.CellTip property. You can provide these tips dynamically by handling the QueryCellStyleInfo event. Here is code that displays the value of a cell Col1 one when the user hovers over a cell in Col2.

//subscribe to the event
            this.gridGroupingControl1.QueryCellStyleInfo += new GridTableCellStyleInfoEventHandler(gridGroupingControl1_QueryCellStyleInfo);


//the event handler
        void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
        {
            if (e.TableCellIdentity.Column != null
                && e.TableCellIdentity.Column.Name == "Col2")
            {
                GridRecord rec = e.TableCellIdentity.DisplayElement.GetRecord() as GridRecord;
                if (rec != null)
                {
                    object val = rec.GetValue("Col1");
                    e.Style.CellTipText = val.ToString();
                }
            }
        }
