SQL - Pivoting on Column and Row Values - sql

Question

I'm trying to Pivot a Table on X and Y position. The table is in a format similar to below.
Each row has a value which is relative to its Row and Column Position.'AThing' and 'FileName' are to be ignored in the data set.
So if this was pivoted we would get:
Iv'e been trying for a while but can't seem to figure it out, any ideas?
EDIT: Number of Fields are dynamic per 'FileName'. I have managed to extract the column names but not the data using:
-- Construct List of Columns to Pivot
SELECT #PivotCols =
STUFF(
(SELECT ',' + QUOTENAME(FieldName)
FROM #Data
GROUP BY ColPos, FieldName
ORDER BY ColPos ASC
FOR XML PATH(''),TYPE).value('.', 'NVARCHAR(MAX)')
,1,1,'')
SET #PivotQuery =
SELECT ' + #PivotCols + N'
FROM
(
SELECT ColPos, FieldName
FROM #Data
GROUP BY ColPos, FieldName
) x
PIVOT
(
MIN(ColPos)
FOR FieldName IN (' + #PivotCols + N')
) p'
EXEC sp_executesql #PivotQuery

Please try this code:
DECLARE #columns NVARCHAR(MAX), #sql NVARCHAR(MAX);
SET #columns = N'';
SELECT #columns += N', p.' + QUOTENAME(FieldName)
FROM (SELECT distinct p.FieldName FROM Tablename AS p
) AS x;
SET #sql = N'
SELECT ' + STUFF(#columns, 1, 2, '') + '
FROM
(
SELECT p.Value, p.FieldName, p.RowPos
FROM Tablename AS p
) AS j
PIVOT
(
MAX(Value) FOR FieldName IN ('
+ STUFF(REPLACE(#columns, ', p.[', ',['), 1, 1, '')
+ ')
) AS p;';
PRINT #sql;
EXEC sp_executesql #sql;
