I have included the code. My problem is that I am always getting the error exception thrown and not caught despite adding cftry/cfcatch blocks. If I don't set selectmode="edit" and include OnChange my grid displays except I get the word false displayed instead of a checkbox. <cfgrid format="html" name="grid_Tables" pagesize="10" autowidth="true" striperows="yes" width = "99%" selectmode="edit" bind="CFC:qry_GetUser.getAllUsers({cfgridpage},{cfgridpagesize},{cfgridsortcolumn},{c fgridsortdirection})"onchange="cfc:qry_GetUser.editData({cfgridaction},{cfgridrow},{cfgridchanged})"> <cfgridcolumn name="UserID" display="No"/> <cfgridcolumn name="opt" header="" type="boolean" width="46"/> <cfgridcolumn name="Name" header="Name" width="150" type="string_nocase" select="no" /> <cfgridcolumn name="Email" header="EMail" width="150" type="string_nocase" select="no" /> <cfgridcolumn name="RegistrationDate" header="Registration Date" width="150" type="string_nocase" select="no" /> </cfgrid> <cffunction name="editData" access="remote"> <cfargument name="gridaction" required="yes"> <cfargument name="gridrow" required="yes" type="Struct"> <cfargument name="gridchanged" required="yes" type="Struct"> </cffunction> The problem is that in edit mode I get an error thrown so the grid doesn't display at all. I am wondering if I have a problem with: onchange="cfc:qry_GetUser.editData({cfgridaction},{cfgridrow},{cfgridchanged}) Right now the editData function does nothing it is empty yet an error is still being thrown. I haven't been able to figure out where the error is being thrown. I have added catch/try blocks around the cfgrid as well as in the editData function but nothing is caught.
