Hello here is the function through which you can interchange the row/ columns of the datatable
private DataTable GenerateTransposedTable(DataTable inputTable)
{
DataTable outputTable = new DataTable();
// Add columns by looping rows
// Header row's first column is same as in inputTable
outputTable.Columns.Add(inputTable.Columns[0].ColumnName.ToString());
// Header row's second column onwards, 'inputTable's first column taken
foreach (DataRow inRow in inputTable.Rows)
{
string newColName = inRow[0].ToString();
outputTable.Columns.Add(newColName);
}
// Add rows by looping columns
for (int rCount = 1; rCount <= inputTable.Columns.Count - 1; rCount++)
{
DataRow newRow = outputTable.NewRow();
// First column is inputTable's Header row's second column
newRow[0] = inputTable.Columns[rCount].ColumnName.ToString();
for (int cCount = 0; cCount <= inputTable.Rows.Count - 1; cCount++)
{
string colValue = inputTable.Rows[cCount][rCount].ToString();
newRow[cCount + 1] = colValue;
}
outputTable.Rows.Add(newRow);
}
return outputTable;
}
Just store the values in datatable and then just pass that datatable in above function you will get new table as transpose of that table
