How to transpose the grid data in WinForms GridGroupingControl?
Transpose the grid data
By default,
separate property is not available to transpose the WinForms
GridGroupingControl, that is, displaying the row data as column data. But
the Grid data can be transposed by changing the DataSource structure from row
to column. This article explains how to transpose data for the GridDataBoundGrid and GridGroupingControl.
For GridControl, please refer to this link: GridControl.
Solution:
The row and column data can be transposed by customizing the DataSource as follows.
GridDataBoundGrid:
The row and column data can be retrieved by using the GridModel. In this customization, the new DataSource is created (transposed data) from these retrieved data and this DataSource is assigned to the Grid.
C#
//Creates the temporary DataTable.
DataTable _GdcTable = new DataTable();
//Creates the columns.
for (int i = 0; i < this.GDBC1Table.Rows.Count; i++)
{
_GdcTable.Columns.Add("Sample" + i);
}
int colCount = this.gridDataBoundGrid1.Model.ColCount;
//Generates the data for the transposed Grid.
for (int c = 1; c <= colCount; c++)
{
DataRow dr = _GdcTable.NewRow();
for (int rowIndex = 1; rowIndex < this.GDBC1Table.Rows.Count; rowIndex++)
{
dr[rowIndex - 1] = this.gridDataBoundGrid1.Model[rowIndex, c].CellValue;
}
_GdcTable.Rows.Add(dr);
}
//Assigns the DataSource.
this._GDBC2Table = _GdcTable;VB
'Creates the temporary DataTable.
Dim _GdcTable As New DataTable()
'Creates the columns.
For i As Integer = 0 To Me.GDBC1Table.Rows.Count - 1
_GdcTable.Columns.Add("Sample" & i)
Next i
Dim colCount As Integer = Me.gridDataBoundGrid1.Model.ColCount
'Generates the data for the transposed Grid.
For c As Integer = 1 To colCount
Dim dr As DataRow = _GdcTable.NewRow()
For rowIndex As Integer = 1 To Me.GDBC1Table.Rows.Count - 1
dr(rowIndex - 1) = Me.gridDataBoundGrid1.Model(rowIndex, c).CellValue
Next rowIndex
_GdcTable.Rows.Add(dr)
Next c
'Assigns the DataSource.
Me._GDBC2Table = _GdcTableGridGroupingControl:
The row and column data can be retrieved by using the Table Records. In this customization, the new DataSource is created (transposed data) from these retrieved data and this DataSource is assigned to the Grid.
C#
//Creates the temporary DataTable.
DataTable _GdcTable = new DataTable();
//Creates the columns.
for (int i = 0; i < this.GGC1Table.Rows.Count; i++)
{
_GdcTable.Columns.Add("Sample" + i);
}
//Generates the data for the transposed Grid.
foreach (GridColumnDescriptor column in this.gridGroupingControl1.TableDescriptor.Columns)
{
DataRow dr = _GdcTable.NewRow();
foreach (Record record in this.gridGroupingControl1.Table.Records)
{
dr[this.gridGroupingControl1.Table.Records.IndexOf(record)] = record.GetValue(column.Name).ToString();
}
_GdcTable.Rows.Add(dr);
}
//Assigns the DataSource.
this._GGC2Table = _GdcTable;VB
'Creates the temporary DataTable.
Dim _GdcTable As New DataTable()
'Creates the columns
For i As Integer = 0 To Me.GGC1Table.Rows.Count - 1
_GdcTable.Columns.Add("Sample" & i)
Next i
'Generates the data for the transposed Grid.
For Each column As GridColumnDescriptor In Me.gridGroupingControl1.TableDescriptor.Columns
Dim dr As DataRow = _GdcTable.NewRow()
For Each record As Record In Me.gridGroupingControl1.Table.Records
dr(Me.gridGroupingControl1.Table.Records.IndexOf(record)) =
record.GetValue(column.Name).ToString()
Next record
_GdcTable.Rows.Add(dr)
Next column
'Assigns the DataSource.
