To perform an action only when an object is not null, you can use:

If Not object Is Nothing
' do your thing
End If

Thanks,I did it.But if datasorce has got some NULL values,the xml created by createnavigator is just skipping that field.

Ex:lets say, i am Retriving A,B,C values from datasource.If B is Null then,createnavigator is returning only A and C values only.It is not even showing B as empty attribute.

My code is still searching for B field.If it is dataset,i could try IsDBnull.How to handle in this case for NULL values.

Thanks,

Aditya.

use

this.DataSources["your_Secondar_datasource"].CreateNavigator();

to get handle to your data of secondary data connection, loop over it and populate your repeating table.

Hi Qazi,

Thanks for your reply.I need bit more help fom u.I would like to connect to my Datasource(which is a webmethod) to retrive data and then i want to populate all the rows of repeating table with that data.I think i couldn't do this auto population of repeating table through Form settings.So i thought of writing some code in Button onclick or dropdown changed event.

Ex:If i get 4 rows from dataset,i would like to populate repeating table 4 times.if 2 rows returned from datatable .I would like to repeat repeating table 2 time.I hope u will understand my task.

this is c# code, i hope you will be able to convert it into vb

XPathNodeIterator listItemNav = this.MainDataSource.CreateNavigator().Select("xpath of your repeating table" this.NamespaceManager);

for (int i = 0; i < listItemNav.Count; i++, listItemNav.MoveNext()) ;

listItemNav.Current.Clone().InsertAfter(listItemNav.Current);
