gridMappingproblem

hi all,

When a map the arraylist to the GridDataBoundGrid
which already have some value bind to it gives the "DuplicateMappingName" error.

I clear the datagrid by assigning its datasource = null,eventhough it produce the same Mapping error.What to do bind to bind new set of records to it.

please give me a solution

Thanks in advance,

Dhana

Hi Dhana,

Try calling the InternalColumns.Clear() method before restting the underlying datasource of the grid. Here is a code snippet.

this.gridDataBoundGrid.Binder.InternalColumns.Clear();
this.gridDataBoundGrid.DataSource = newArraylist;

hi haneef!

when My code is like this..

aCurrentList =new CLIList();
aCurrentList = ELActions.Session.BidSheet(ELActions.Session.CurrentProject); // arraylist
dgCurrentTransaction.DataSource =ELActions.Session.BidSheet(ELActions.Session.CurrentProject);//binding to grid.

i am getting error which i attached to u.

when i include code given by u before assigning arraylist like..

this.dgCurrentTransaction.Binder.InternalColumns.Clear();
aCurrentList =new CLIList();
aCurrentList = ELActions.Session.BidSheet(ELActions.Session.CurrentProject);
dgCurrentTransaction.DataSource =ELActions.Session.BidSheet(ELActions.Session.CurrentProject);

then it creates error "Input string in correct Format"

please suggest me a idea

Hi Dhana,

We are not sure of what be might be causing this strange behavior without a working sample. Are you setting any cellvalue of the cell dynamically using QueryCellInfo/PrepareViewStyle event? Please post us a sample showing this problem, which will help us to find the issue and resolve this.

Thanks for your patience.
