I have 10 txt files . given below are 3 txt files named as "A.txt" ,"B.txt","c.txt",.likewise we have 10 txt files .

A  B1.asd
1   0.1
2   0.2
3   0.3

A   B2.asd
1   0.7
2   0.1
3   0.4

A   B3.asd
1   0.6
2   0.4
3   0.12

Now I have merged all these files and saved ouput in a new file where the data appears like this :

A   B1.asd
1   0.1
2   0.2
3   0.3
A   B2.asd
1   0.7
2   0.1
3   0.4
A   B3.asd
1   0.6
2   0.4
3   0.12

My question is : I want to import this data to datagridview where my output appears like this : as first field is common to all so we eliminate it .

B1.asd B2.asd B3.asd
0.1 0.7 0.6
0.2 0.1 0.4
0.3 0.4 0.12

anybody know answer/code pls reply
