I think you will need a new DataView for the export then re-assign the original DataSet as DataSource after the export. If you wrap the Export process inside BeginUpdate() and EndUpdate() then the user will not see that you are replacing the UltraGrid's Datasource.

hi,

I am facing the same problem .

 I have a parent grid having data as 

Parent header : Header1  Header2  Header3

Parent data     : HData1    HData2    HData 3

Child Header :  Childheader1    Childheader2 

Child data    : data1                data2

                    data11               data22

I want to display it in excel sheet as :

Header1  Header2 Header3 Childheader1 Childheader2 

HData1    HData2  HData3   data1                data2    

                                        data11               data22  

Can you please give a sample code having the same scenario , as i am unable to fulfill this .

The headers of the Parent grid are getting repeated every time the data of the child grid is displayed along with blank rows.

Please help me in this .

Thanks in advance.

Then pass the grid to UltraGridExcelExporter.  However no data got exported.  I think by creating an UltraGrid on the fly does not do the job as the grid is not visible.

You probably need to add the grid to the form's Controls collection so that it has a BindingContext. Or, you could just set the grid's BindingContext to the form's BindingContext.

I have managed to move the cells by using events HeaderExporting and CellExporting( please see code sample below).   But after moving the cells I have blank lines left by band 1 data.  I cannot figure out a way to remove them.  Is there any library in infragistics or .Net would allow me to open up the spreadsheet and remove the blank liines in one go?

There's no way to remove lines. You would have to stop those lines from being created in the first place. You should be able to do this by setting the CurrentRowIndex inside the event of the UltraGridExcelExporter.

Hi Mike

Yes I have only 1 child row per parent.  I have tried to below:

UltraGrid grid = new UltraGrid();

grid.DataSource = data <--single band data

Then pass the grid to UltraGridExcelExporter.  However no data got exported.  I think by creating an UltraGrid on the fly does not do the job as the grid is not visible.

Many thanks

void excelExporter_CellExporting(object sender, CellExportingEventArgs e)

{

//moving the cell value in band[1] to the same level as band[0]

//setting the format of the cell to which it has moved to the same format cell before it.

Hi Lan,

So... you only have one child row for each parent row?

How are you changing the export so that it comes out this way in Excel?

There are a couple of ways you could acheive what you want.

One way would be to create a new grid and a new UltraDataSource with a single band and then copy the data into the UltraDataSource which is bound to the new grid. Then you could export this new grid so it would all be one band.

Another option would be to try to handle this using the events of the UltraGridExcelExporter. Events like RowExporting/RowExported and HeaderExporting/HeaderExported all have proeprties on the event args for CurrentRowIndex and CurrentColumnIndex. So you could change these numbers so that the export occurs at a particular place within the excel document. It might be a bit tricky to work out the numbers. I guess you would have to store the row and column index of the last header and the last cell that was exported in the parent row and then use those numbers to place the child row to the right of it.
