How do we do this with gridboundgrid. http://support.microsoft.com/default.aspx?scid=kb;en-us;318581 Basically, i want to intercept the value coming from the datasource, do some processing, then display a new value. Thanks Trevor

Hi Trevor, you can use DrawDisplayText Event for appending a string with a numeric value. Here is the code snippet. private void gridDataBoundGrid1_DrawCellDisplayText(object sender, Syncfusion.Windows.Forms.Grid.GridDrawCellDisplayTextEventArgs e) { if(e.Style.CellIdentity.ColIndex == 1 && e.Style.CellIdentity.RowIndex > 0) e.DisplayText = "$" + e.DisplayText; } Refer to sample for more details. Let me know, if you need futher assistance. Regards, Madhan.

What i actually want to do is take the data coming from the column in the data source, use this data as a key for a lookup in a hashtable, then display the corresponding value from the Hashtable. Is this event a suitable place to do this? Thanks Trevor

Hi Trevor, To format the Cell Text ,you need to handle either QueryCellFormattedText Eventhandler/ DrawCellDisplayText Event Handler. Refer to modified sample for more details For DrawCellDisplayText Event Handle: private void gridDataBoundGrid1_DrawCellDisplayText(object sender, Syncfusion.Windows.Forms.Grid.GridDrawCellDisplayTextEventArgs e) { GridModel model = this.gridDataBoundGrid1.Model; if(e.Style.CellIdentity.RowIndex > 0 && e.Style.CellIdentity.ColIndex == 1) { int keyColIndex = model.NameToColIndex("ParentID"); string key = model[e.Style.CellIdentity.RowIndex, keyColIndex].Text; e.Style.Description = key; if (key != null) { object value = celltable[key]; if (value != null) e.DisplayText = value.ToString()+ e.DisplayText; } } } For QueryCellFormattedText Event Handler: Refer this KB article - http://www.syncfusion.com/support/kb/grid/Default.aspx?ToDo=view&questId=333 Let me know if you need futher assistance, Regards, Madhan.
