Hi Telerik,

I think we have found a minor bug in the Pivot Table Sample for RadGrid where the PivotTable() method skips the first column of the table when it converts a vertical table structure to a horizontal structure.

Here is the code:

Please redeem us some points if we are first to report this :).

Regards,

Amir

public DataTable PivotTable(DataTable source)
{
DataTable dest = new DataTable("Pivoted" + source.TableName);

dest.Columns.Add(" ");

foreach (DataRow r in source.Rows)
dest.Columns.Add(r[0].ToString());

for (int i = 0; i < source.Columns.Count - 1; i++)      // Columns count should not be decreased by one
{
dest.Rows.Add(dest.NewRow());
}

for (int r = 0; r < dest.Rows.Count; r++)
{
for (int c = 0; c < dest.Columns.Count; c++)
{
if (c == 0)
dest.Rows[r][0] = source.Columns[r + 1].ColumnName; // Row index should not be increased by one
else
dest.Rows[r][c] = source.Rows[c - 1][r + 1]; // Row index should not be increased by one
}
}
dest.AcceptChanges();
return dest;
        }

Hello Amir,

I review the mentioned demo and I can confirm data is displayed properly there. Can you specify what how data is displayed in regular and pivot grid in your case so we can check it further?

All the best,
