[Solved] Grouping with nested tables

[emidio rana]

When I have grouped a grid, with nested table, in columns and in the prerender event i hided some of gruped results happen that remain a spaces in the grid.
I'm try in all ways to remove that spaces but without success.
I see that the spaces disappear when I open and collapse a grouped row.
In the attached file can you see the result's grid.
This is the code.

For Each item As GridGroupHeaderItem In gridTelerik.MasterTableView.GetItems(GridItemType.GroupHeader)

item.Expanded = False

Dim groupDataRow As DataRowView = CType(item.DataItem, DataRowView)

If item.DataCell.Text.IndexOf("Partita:") > -1 Then

item.DataCell.Text = item.DataCell.Text.Replace(item.DataCell.Text.Substring(9, 8), "")

Dim StrdtReverse As String = item.DataCell.Text.Substring(item.DataCell.Text.Length - 10, 10)

Dim StrdtReverseConcat As String = String.Concat(StrdtReverse.Substring(6, 4), StrdtReverse.Substring(3, 2), StrdtReverse.Substring(0, 2))

Dim dtRowPartita() As DataRow = dataTableEstrattoConto.Select(String.Concat("Partita='", StrdtReverseConcat, item.DataCell.Text.Replace("Partita: ", ""), "'"))

For ik As Integer = 0 To dtRowPartita.Length - 1

totaleNettoPartita += Convert.ToDecimal(dtRowPartita(ik).Item("Importonetto"))

Next

item.DataCell.Text = String.Concat("Saldo partita: <b>", String.Format("{0:n2}", totaleNettoPartita), "</b>")

totaleNettoPartita = 0

End If

'item.DataCell.Text = "$" + groupDataRow("Cliente").ToString() + " (" + groupDataRow("Importonetto").ToString() + ")"

If item.DataCell.Text.IndexOf("Cliente:") > -1 Then

Dim dtRowCliente() As DataRow = dataTableEstrattoConto.Select(String.Concat("Cliente='", item.DataCell.Text.Replace("Cliente: ", ""), "'"))

For ik As Integer = 0 To dtRowCliente.Length - 1

totaleNetto += Convert.ToDecimal(dtRowCliente(ik).Item("Importonetto"))

totaleRitenuta += Convert.ToDecimal(dtRowCliente(ik).Item("Importoritenuta"))

totaleLordo += Convert.ToDecimal(dtRowCliente(ik).Item("Importolordo"))

totaleImponibileRitenuta += Convert.ToDecimal(dtRowCliente(ik).Item("Imponibileritenutaacconto"))

Next

item.DataCell.Text = String.Concat(groupDataRow("Cliente").ToString().TrimStart, "<br> <b>TOTALI: Importo lordo:</b> ", String.Format("{0:n2}", totaleLordo), _

" - <b>Imponibile ritenuta acconto:</b> ", String.Format("{0:n2}", totaleImponibileRitenuta), _

" - <b>Importo ritenuta:</b> ", String.Format("{0:n2}", totaleRitenuta), " - <b>Importo netto:</b> ", String.Format("{0:n2}", totaleNetto))

If totaleLordo = 0 Then

If (Request.QueryString("st") Is Nothing) Or _

(Not Request.QueryString("st") Is Nothing AndAlso Request.QueryString("St").ToString <> "1") Then

'se le partite si pareggiano tra di loro, perch ad es. c' una nota di credito in un altra partita

'non rendo visibile il tab

item.Visible = False

item.Display = False

item.Expanded = False

End If

End If

totaleGenerale += totaleNetto

totaleLordo = 0

totaleNetto = 0

totaleRitenuta = 0

totaleImponibileRitenuta = 0

End If

Next

Hello Emidio,

I was not able to reproduce the issue. I prepared a small sample and attached it to this thread. Please give it a try and let me know how it differs from your real setup.

Kind regards,
