Hi,

  Depending on the amount of bands depends on the complexity needed for the solution. Do you just have two bands, the root band, which is Band[0], and a child band, Band[1]. Are there more than that? If there are more, is it a simple hierarchy of Root, Child, GrandChild, Great GrandChild,... or are there sibling bands? IE Root, Child1, Child2, GrandChild1(Child of Child1), GrandChild2(Child of Child1), ... the grid has many possible data possibilities, and while it may be possible to create a means to work with all of them, the complexity would likely be far greater than you need.

   That being said, I will start off with the basic, and give you the general idea on how to build from there. For starters, most of the Grid actions use three basic parameters. RowPathArg, ColumnArg, and ColumnPathArg.

  The RowPathArg is typically the most complex, in most cases you will likely just use a simple numeric, for rows on the root band. It's when you start dealing in hierarchical data that it gets trickier to have all the possibilities be delineable by one parameter.  The parameters parsing structure looks like this

"iRowIndex0;[[iChildBandIndex1,]iRowIndex1][;[[iChildBandIndexN,]iRowIndexN];]..."

Seems rather complex but to simplify it by the following statements :
    Each generation level requires a iRowIndex
    Each generation level can have a sibling band specified, if not ChildBand 0 is assumed
    Each generation level, if an iChildBandIndex is needed, is listed first delimited from its row by a comma
    Each generation level is delimited by a semi-colon
    Each iIndex is for a zero based collection, where 0 is the first item

For simple rows you can use a numeric string such as "3" or simply the integer 3.

For simple hierarchical rows you need to use semi-colon delimited string "1;3" or "0;3;4" etc

For complex hierarchical rows with sibling bands "3;1,3"

ColumnArg is much simpler, its the zero based index or the ColumnKey.

ColumnPathArg, which is mostly ever used when dealing with a column by itself without a row, is a semi-colon delimited string of iBandIndex and sColumnKey or iColumnIndex. So something like "0;Name" or "1;2"

    That all being said, from how I interpret what you are asking is that you have two band, the root, Band[0] with one child band Band[1], and you want to select each row of the child band.  That can be done as follows:

SET grid = SwfWindow("Form1").SwfTable("ultraGrid1")

grid.ActivateRow "0"
iRowCount = grid.RowCount

FOR iRow = 0 TO iRowCount - 1
    iChildBandCount = grid.GetNAProperty("Rows["+CSTR(iRow)+"].ChildBands.Count")

    IF iChildBandCount > 0 THEN
        grid.ExpandRow CSTR(iRow)

        iChildRowCount = grid.GetNAProperty("Rows["+CSTR(iRow)+"].ChildBands[0].Rows.Count")

        IF iChildRowCount > 0 THEN
            FOR iChildRow = 0 TO iChildRowCount - 1
                rowPathArg = CSTR(iRow) +";" +CSTR(iChildRow)
                grid.SelectRow rowPathArg
            Next
           
        END IF   
    END IF
NEXT

I hope that answers your question,
