Hello,Shehnaaz
While binding data to matrix u have to use datasources
Steps
1.Create one datasourece
Declare
assign ur matrix table like this
oDB_Row = oForm.DataSources.DBDataSources.Item("@VEDA_TC_DLN")
2. Give here loop
rs.MoveFirst()
        For I = 1 To rs.RecordCount
            oMatrix.AddRow()
            oDBs_Head.SetValue("LineID", oDBs_Head.Offset, oMatrix.VisualRowCount)
            oDBs_Head.SetValue("U_BobNo", oDBs_Head.Offset, rs.Fields.Item("U_BobNo").Value)
            oDBs_Head.SetValue("U_CovSze", oDBs_Head.Offset, rs.Fields.Item("U_CovSze").Value)
            oDBs_Head.SetValue("U_BrWid", oDBs_Head.Offset, rs.Fields.Item("U_BrWid").Value)
            oDBs_Head.SetValue("U_BrThi", oDBs_Head.Offset, rs.Fields.Item("U_BrThi").Value)
            oDBs_Head.SetValue("U_Flex", oDBs_Head.Offset, rs.Fields.Item("U_Flex").Value)
            oDBs_Head.SetValue("U_Adh", oDBs_Head.Offset, rs.Fields.Item("U_Adh").Value)
            oDBs_Head.SetValue("U_Elog", oDBs_Head.Offset, rs.Fields.Item("U_Elog").Value)
            oDBs_Head.SetValue("U_UTS", oDBs_Head.Offset, rs.Fields.Item("U_UTS").Value)
            oDBs_Head.SetValue("U_Hard", oDBs_Head.Offset, rs.Fields.Item("U_Hard").Value)
            oDBs_Head.SetValue("U_BDVRt", oDBs_Head.Offset, rs.Fields.Item("U_BDVRt").Value)
            oDBs_Head.SetValue("U_BDVEt", oDBs_Head.Offset, rs.Fields.Item("U_BDVEt").Value)
            oDBs_Head.SetValue("U_Scrap", oDBs_Head.Offset, rs.Fields.Item("U_Scrap").Value)
            oDBs_Head.SetValue("U_Aprvd", oDBs_Head.Offset, rs.Fields.Item("U_Aprvd").Value)
            oDBs_Head.SetValue("U_BsLineId", oDBs_Head.Offset, InsBaseRow)
            oDBs_Head.SetValue("U_BsDoc", oDBs_Head.Offset, InsBaseDoc)
            oMatrix.SetLineData(oMatrix.VisualRowCount)
            rs.MoveNext()
        Next
3.Try to under stand setline data is very important if did nt mension set line data means that will not display any data
Hope this will help u
